     THIS AMENDMENT NO. 2 (this "Amendment"), dated as of July 25, 2000, to the
Third Amended and Restated Investor Agreement, dated as of September 9, 1997, as

"Company"), and Security Capital Group Incorporated, a Maryland corporation

     WHEREAS, pursuant to a Purchase and Sale Agreement, dated as of July 19,
2000 (the "Purchase and Sale Agreement"), between the Company and SCG, SCG has
agreed to sell to the Company certain Common Shares in exchange for the
consideration described therein; and

     WHEREAS, as a condition to the closing of the transactions contemplated by
the Purchase and Sale Agreement, the parties have agreed to amend the Agreement

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained in this Amendment and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereby
amend the Agreement as follows:

     (a)  Section 5(b) of the Agreement is hereby amended and restated in its
entirety as follows:

     "    (b)  File Reports. For so long as SCG shall continue to Beneficially

     quarterly and other reports required to be filed by it under Sections 13
     and 15(d) of the Exchange Act, and the Rules and Regulations of the
     Commission thereunder, as amended from time to time; provided, however,
     that for so long as SCG Beneficially Owns at least 10% of the outstanding
     Common Shares, the Company shall use its best efforts to file such reports
     at least two (2) business days prior to the day on which such reports would
     otherwise be required to be filed under Sections 13 and 15(d) of the
     Exchange Act, and the Rules and Regulations of the Commission thereunder,
     as amended from time to time."

     (b)  The following new subsections (j) and (k) are hereby added to the end
of Section 5 of the Agreement:

     "    (j)  Board Committees. For so long as SCG shall continue to be
               ----------------
     entitled to designate one or more Nominees, the Company shall use its best
     efforts to cause one of such Nominees as designated by SCG to serve on each

          (k)  Reports. For so long as SCG shall continue to Beneficially Own at
               -------
     least 10% of the outstanding Common Shares, the Company shall provide SCG,
     on a timely basis, monthly operating and financial reports prepared in the
     Company's customary form."

     (c)  Section 7(a) of the Agreement is hereby amended by adding the
following sentence to the end thereof:

     "Without limiting the generality of the foregoing, SCG may request
     registration of all or any part of its Registrable Securities, which
     Registrable Securities are proposed to be sold or transferred by SCG upon
     conversion or exchange of convertible or exchangeable securities of SCG to
     be issued by SCG in a transaction registered under the Securities Act, and
     the Company will use its reasonable efforts to effect the registration of
     such Registrable Securities under the Securities Act, to the extent that
     such registration is permitted under the Securities Act and the Rules and
     Regulations of the Commission thereunder."

     (d)  Sections 7(b)(i) and (b)(ii) are hereby amended and restated in their
entirety as follows:

          "    (i)  prepare and file with the Commission a registration
          statement with respect to such securities and use its reasonable
          efforts to cause such registration statement to become effective and
          remain effective for as long as shall be necessary to complete the
          distribution of the Registrable Securities so registered;

               (ii) prepare and file with the Commission such amendments and
          supplements to such registration statement, and the prospectus used in
          connection therewith, as may be necessary to keep such registration
          statement effective for so long as shall be necessary to complete the
          distribution of the Registrable Securities so registered and to comply
          with the provisions of the Securities Act with respect to the sale or
          other disposition of all securities covered by such registration
          statement whenever SCG shall desire to sell or otherwise dispose of
          the same within such period;"

     (e)  Section 7(i) of the Agreement is hereby amended by adding the
following provisions to the end thereof:

     "SCG may assign without the consent of the Company, all or any portion of,
     its rights under this Section 7 with respect to any Registrable Securities
     to one or more Persons (each, a "Transferee" and together "Transferees") to
     whom SCG has issued or sold, in a transaction not registered or required to
     be registered under the Securities Act, any security convertible into or
     exchangeable for at least $100 million in Value of Registrable Securities.
     If SCG assigns its rights under this Section 7 with respect to Registrable
     Securities having an aggregate offering value of at least $100 million to
     one or more Transferees, the Transferees may request one registration of

                                     -2-
<PAGE>

     all or part of the Registrable Securities having an aggregate offering
     value of at least $100 million on Form S-3 (or any successor form) under
     the Securities Act by delivering written notice to the Company specifying
     the number of Registrable Securities that the Transferees desire to sell
     and the Company shall use its reasonable efforts to effect the registration
     of such Registrable Securities under the Securities Act in accordance with
     and subject to the provisions of this Section 7. For the avoidance of
     doubt, and notwithstanding anything contained herein, any rights under this
     Section 7 not expressly assigned by SCG shall deemed to be retained by SCG,
     and SCG shall continue to be entitled to registration rights hereunder with
     respect to Registrable Securities Beneficially Owned by it, subject to the
     terms hereof."

     (f)  "Executive and Investment Committee" shall mean the committee of the
Board primarily responsible for acting on behalf of the entire Board between
regular Board meetings, reviewing and making recommendations regarding strategic
actions; pricing securities to be issued by the Company and reviewing and
approving proposed investments and property dispositions, including any such
successor or replacement committee.

          "Management Development and Executive Compensation Committee" shall
mean the committee of the Board primarily responsible for reviewing and
approving the Company's executive compensation arrangements and plans including
any such successor or replacement committee.

     (g)  Capitalized terms used in this Amendment but not specifically defined
herein shall have the meanings ascribed thereto in the Agreement.

     (h)  Except as otherwise specifically modified hereby, the Agreement shall
remain in full force and effect.

     (i)  This Amendment shall be governed by, and construed and enforced in
accordance with, the laws of the State of Maryland.

     (j)  This Amendment may be executed in any number of counterparts, each of
which may be deemed an original and all of which together shall constitute one
and the same instrument.

     (k)  The miscellaneous provisions of Section 8 of the Agreement shall apply
equally to this Amendment, and to the Agreement as modified hereby.

                           *     *     *     *     *

branch or Affiliate of such Lender to make such Loan, provided that any exercise
                                                      --------
of such option shall not (A) affect the obligation of the applicable Borrower to

any reimbursement or other payment to be made to such Lender or its Affiliates
pursuant to Section 2.20 in an amount in excess of the amounts that would have
            ------------
been payable thereunder to such Lender had such Lender not exercised such
option. Borrowings of more than one Type may be outstanding at the same time;
provided, however, that the Borrowers shall not be entitled to request any
--------  -------
Borrowing that, if made, would result in an aggregate of more than fifteen
separate Eurodollar Loans and five B/A Borrowings of any Lender being
outstanding hereunder at any one time. For purposes of the foregoing, Loans
having different Interest Periods or Contract Periods or denominated in
different currencies, regardless of whether they commence on the same date,
shall be considered separate Loans.

     (c) Subject to paragraph (e) below, each Lender shall make a Loan in the
amount of its pro rata portion, as determined under Section 2.17, of each
                                                    ------------
Borrowing hereunder on the proposed date thereof by wire transfer of immediately
available funds to the Administrative Agent in New York, New York (or to the
Canadian Administrative Agent in Toronto, Ontario, in the case of any Loan
denominated in Canadian Dollars), not later than 2:00 p.m., Standard Time, and
the Administrative Agent shall promptly credit the amounts so received to the
general deposit account of the Borrower or, if a Borrowing shall not occur on
such date because any condition precedent specified herein shall not have been
met, return the amounts so received to the respective Lenders. Unless the
Administrative Agent shall have received notice from a Lender prior to the date
of any Borrowing (or, in the case of an ABR Revolving Borrowing or Canadian
Prime Rate Borrowing, prior to 2:00 p.m., Standard Time, on the date of such
Borrowing) that such Lender will not make available to the Administrative Agent
such Lender's portion of such Borrowing, the Administrative Agent may assume
that such Lender has made such portion available to the Administrative Agent on
the date of such Borrowing in accordance with this paragraph (c) and the
                                                   -------------
Administrative Agent may, in reliance upon such assumption, make available to
the applicable Borrower on such date a corresponding amount. If and to the
extent that such Lender shall not have made such portion available to the
Administrative Agent, such Lender and such Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to such Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of such Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Effective Rate or, in the case of a Revolving Credit Borrowing
denominated in Canadian Dollars, the rate determined by the Administrative Agent
to represent its cost of obtaining overnight Canadian Dollars. If such Lender
shall repay to the Administrative Agent such corresponding amount, such amount
shall be deemed to constitute such Lender's Loan as part of such Borrowing for
purposes of this Agreement.

     (d) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Interest Period (or Contract Period in the
case of a B/A Borrowing) with respect to any Revolving Credit Borrowing that
would end after the Revolving Credit Maturity Date.

     (e) If the  Facing  Agent  has not  received  from  Canco  the  payment
required by paragraph (d) of Article III within two hours after Canco shall have

payment of a drawing presented under any Letter of Credit will be made or, if
Canco shall have received such notice later than 10:00 a.m., Standard Time, on
any Business Day, not later than 10:00 a.m., Standard Time, on the immediately
following Business Day, as provided in paragraph (a) of Article III, the Facing
Agent will promptly notify the Canadian Administrative Agent of the LC
Disbursement and the Administrative Agent will promptly notify each Revolving
Lender of such LC Disbursement and its Applicable Percentage thereof. Each
Revolving Lender will pay to the Canadian Administrative Agent not later than
4:00 p.m., Standard Time on such date (or, if the Revolving Lenders shall have
received such notice later than 2:00 p.m., Standard Time, on any day, not later
than 10:00 a.m., Standard Time, on the immediately following Business Day) an
amount equal to such Revolving Lender's Applicable Percentage of such LC
Disbursement (it being understood that such amount shall be deemed to constitute
an ABR Revolving Loan or Canadian Prime Rate Revolving Loan, as the case may be,
of such Revolving Lender), and the Canadian Administrative Agent will promptly
pay such amount to the Facing Agent. The Canadian Administrative Agent will
promptly remit to each Revolving Lender its Applicable Percentage of any amounts
subsequently received by the Canadian Administrative Agent from the Borrower in
respect of such LC Disbursement. If any Lender shall not have made its
Applicable Percentage of such LC Disbursement available to the Facing Agent as
provided above, such Lender agrees to pay interest on such amount, for each day
from and including the date such amount is required to be paid in accordance
with this subsection to but excluding the date an amount equal to such amount is
paid to the Canadian Administrative Agent for prompt payment to the Facing Agent
at, for the first such day, the overnight Canadian interbank rate for U.S.
Dollars or Canadian Dollars, as the case may be, and for each day thereafter,
the Alternate Base Rate or the Canadian Prime Rate, as the case may be.

-------------
such notice, then the requested Borrowing shall be an ABR Borrowing if
denominated in U.S. Dollars and a Canadian Prime Rate Borrowing if denominated
in Canadian Dollars. If no Interest Period with respect to any Eurodollar
Borrowing (or Contract Period, with respect to a B/A Borrowing) is specified in
any such notice, then the Borrower shall be deemed to have selected an Interest
Period (or Contract Period in the case of a B/A Borrowing) of one month's (or 30
days', in the case of a B/A Borrowing) duration. The Administrative Agent shall
promptly advise the Lenders of any notice given pursuant to this Section, and of
each Lender's portion of the requested Borrowing, but in any event prior to
12:00 noon, Standard Time, for same day Borrowings.

     SECTION 2.04.  Repayment of Loans; Evidence of Debt. (a) Canco hereby

Except for any B/A Loan (the compensation for which is set forth in Section
                                                                    -------

     (b) Each Lender shall maintain in accordance with its usual practice an

not in any manner affect the obligation of either Borrower to repay the Loans in
accordance with their terms.

     (e) Any Lender may request from time to time that its Revolving Loans,
Tranche G Loans or Tranche H Loans be evidenced by a promissory note. In
response to any such request, the applicable Borrower shall prepare, execute and
deliver to such Lender a promissory note payable to such Lender and its
registered assigns, substantially in the form of Exhibit I-1, in the case of a

in the event that any Lender shall request and receive such a promissory note,
the Loans evidenced by such promissory note and interest payable on such Loans
shall at all times (including after assignment pursuant to Section 11.04) be
                                                           --------------
represented by one or more promissory notes payable to the payee named therein
and its registered assigns.

     SECTION 2.05.  Fees. (a) Canco agrees to pay to each Revolving Lender, in
respect of the Revolving Credit Commitments of such Lender to such Borrower,

Commitments of such Lender during the preceding quarter (or other period
commencing on the Closing Date or ending with the Revolving Credit Maturity Date

terminated). The Commitment Fee due to each Lender shall commence to accrue on
and including the Closing Date and shall cease to accrue on, but excluding, the

to unreimbursed LC Disbursements) during the preceding quarter (or shorter
period commencing with the Closing Date or ending with the Revolving Credit
Maturity Date or the date on which all Letters of Credit have been canceled or
have expired and the Revolving Credit Commitments of all Lenders shall have been
terminated) at a rate equal to the greater of (x) the Applicable Rate from time
to time used to determine the interest rate on Eurodollar Revolving Credit
Borrowings pursuant to Section 2.06 minus 0.50% and (y) 1.00%, (ii) to the

     SECTION 2.06.  Interest on Loans. (a) Subject to the provisions of Section
                                                                        -------
2.07, the Loans comprising each ABR Borrowing shall bear interest (computed on
----
the basis of the actual number of days elapsed over a year of 365 or 366 days,
as the case may be, when the Alternate Base Rate is determined by reference to
the Prime Rate or the U.S. Base Rate and over a year of 360 days at all other
times) at a rate per annum equal to the Alternate Base Rate plus the Applicable
Rate in effect at such time with respect to such Loans.

     (b) Subject to the provisions of Section 2.07, the Loans comprising each
                                      ------------
Eurodollar Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 360 days) at a rate per annum equal to the
Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
                                                                        ----
Applicable Rate in effect at such time with respect to such Loans.

     (c) Subject to the provisions of Section 2.07, the Loans comprising each
                                      ------------
Canadian Prime Rate Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be) at a rate per annum equal to the Canadian Prime Rate plus the Applicable
Rate in effect at such time with respect to such Loans.

     (d) Subject to the provisions of Section 2.07, the Loans comprising each
                                      ------------
B/A Borrowing shall be subject to an Acceptance Fee, payable by Canco on the
date of acceptance of the relevant B/A and calculated as set forth in the
definition of the term "Acceptance Fee" in Section 1.01.
                                           ------------

     (e) Interest on each Loan (other than pursuant to a B/A Borrowing) shall be
payable on the Interest Payment Dates applicable to such Loan, except as
otherwise provided in this Agreement. The Applicable Rate for each Interest
Period or day within an Interest Period, as the case may be, shall be determined
by the Administrative Agent or the Canadian Administrative Agent, as applicable,
and such determination shall be presumptively correct absent manifest error.

     (f) For the purposes of the Interest Act (Canada) and disclosure
thereunder, whenever any interest or fee to be paid hereunder or in connection
herewith is to be calculated on the basis of any period of time that is less
than a calendar year, the yearly rate of interest to which the rate used in such
calculation is equivalent is the rate so used multiplied by the actual number of
days in the
<PAGE>

                                                                              39

calendar year in which the same is to be ascertained and divided by 360, 365 or
366, as applicable. 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 2.07. Default Interest. If either Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder or under any Loan Document, by acceleration or otherwise, the
applicable Borrower shall on demand from time to time pay interest, to the
extent permitted by law, on such defaulted amount to but excluding the date of
actual payment (after as well as before judgment or bankruptcy) at a rate per
annum (the "Default Rate") equal to (a) in the case of any Loan, the rate that
            ------------
would be applicable under Section 2.06 to such Loan plus 2.00% per annum and (b)
                          ------------              ----
in the case of any other amount, the rate that would be applicable under Section
                                                                         -------
2.06 to an ABR Revolving Loan plus 2.00% per annum.
----

     SECTION 2.08.  Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined that dollar deposits in the principal amounts of the Loans comprising
such Borrowing are not generally available in the London interbank market, or
that the rates at which such dollar deposits are being offered will not
adequately and fairly reflect the cost to Lenders having outstanding Loans and
unused Commitments representing at least 20% of the aggregate outstanding Loans
and unused Commitments in respect of the affected Credit Facility of making or
maintaining their Eurodollar Loans during such Interest Period, or that
reasonable means do not exist for ascertaining the Adjusted LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to each Borrower and the Lenders. In the
event of any such determination, any request by either Borrower for a Eurodollar
Borrowing pursuant to Section 2.03 or 2.10 shall, until the Administrative Agent
                      ------------    ----
shall have advised the Borrowers and the Lenders that the circumstances giving
rise to such notice no longer exist, be deemed to be a request for an ABR
Borrowing. Each determination by the Administrative Agent hereunder shall be
conclusive absent manifest error.

     SECTION 2.09.  Termination and Reduction of Commitments. (a) The Term Loan
Commitments shall terminate at 5:00 p.m., Standard Time, on the Closing Date.
The Revolving Credit Commitments shall terminate at 5:00 p.m., Standard Time, on
the Revolving Credit Maturity Date.

     (b) Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, (x) Stone may at any time in whole
permanently terminate, or from time to time in part permanently reduce, the
Tranche G Commitments and (y) Canco may at any time in whole permanently
terminate, or from time to time in part permanently reduce, the Tranche H
Commitments and/or the Revolving Credit Commitments; provided, however, that (i)
                                                     --------  -------
each partial reduction of such Commitments shall be in an integral multiple of
U.S.$1,000,000 and in a minimum principal amount of U.S.$5,000,000 and (ii)
Canco shall not be permitted to terminate or reduce the Revolving Credit
Commitments if, as the result of such termination or reduction, the Revolving
Credit Utilization would exceed the aggregate remaining Revolving Credit
Commitments.

     (c) The Revolving Credit Commitments shall be permanently reduced by the
amount of any mandatory prepayments applied to Revolving Credit Borrowings
pursuant to Section 2.13(f).
            ---------------

     (d) Each reduction in the Commitments hereunder shall be made ratably among
the applicable Lenders in accordance with their respective applicable
Commitments.

     (e) The applicable Borrower shall pay to the Administrative Agent for
account of the applicable Lenders, on the date of each termination or reduction,
the Commitment Fees on the amount of the Commitments so terminated or reduced
accrued to, but excluding, the date of such termination or reduction.

     (f) Nothing in this Section 2.09 shall prejudice any rights that either
                         ------------
Borrower may have against any Lender that fails to lend as required hereunder
prior to the date of termination of any Commitment.

     SECTION 2.10. Conversion and Continuation of Borrowings. Each Borrower
shall have the right at any time upon prior irrevocable notice to the
Administrative Agent (i) not later than 11:00 a.m., Standard Time, on the day of
the proposed conversion, to convert any Eurodollar Borrowing into an ABR
Borrowing or to convert any B/A Borrowing to a Canadian Prime Rate Borrowing,
(ii) not later than 11:00 a.m., Standard Time, three Business Days prior to

          (a) each conversion or continuation shall be made pro rata among the
     Lenders in accordance with the respective principal amounts of the Loans
     comprising the converted or continued Borrowing;

          (b) if less than all the outstanding principal amount of any Borrowing
     shall be converted or continued, then each resulting Borrowing shall
     satisfy the limitations specified in Sections 2.02(a) and (b) and, if
                                          ----------------     ---
     applicable, Section 2.22, regarding the principal amount and maximum number
                 ------------
     of Borrowings of the relevant Type;

          (c) each conversion shall be effected by each Lender and the
     Administrative Agent by recording the particulars thereof in their
     respective records, and no new Loan shall be considered to have been made
     as a result thereof; accrued interest on any Eurodollar Loan (or portion
     thereof) being converted shall be paid by the applicable Borrower at the
     time of the conversion;
<PAGE>

                                                                              41

          (d) if any Eurodollar Borrowing or B/A Loan is converted at a time
     other than the end of the Interest Period applicable thereto, the
     applicable Borrower shall pay, upon demand, any amounts due to the Lenders
     pursuant to Section 2.16;
                 ------------

          (e) any portion of a Borrowing maturing or required to be repaid in

     Borrowing or a B/A Borrowing;

          (f) any portion of a Eurodollar Borrowing or a B/A Borrowing that
     cannot be converted into or continued as a Eurodollar Borrowing or a B/A
     Borrowing by reason of paragraph (e) above shall be automatically converted
     at the end of the Interest Period or Contract Period in effect for such
     Borrowing into an ABR Borrowing or a Canadian Prime Rate Borrowing, as the
     case may be; and

          (g) no Interest Period may be selected for any Eurodollar Term
     Borrowing that would end later than any applicable Term Loan Repayment Date
     occurring on or after the first day of such Interest Period if, after
     giving effect to such selection, the aggregate outstanding amount of (i)
     the Eurodollar Term Borrowings with Interest Periods ending on or prior to
     such Term Loan Repayment Date and (ii) the ABR Term Borrowings would not be
     at least equal to the principal amount of Term Borrowings to be paid on
     such Term Loan Repayment Date.

         Each notice pursuant to this Section 2.10 shall be irrevocable and
                                      ------------
shall refer to this Agreement and specify (i) the identity, amount and Class of
the Borrowing that the Borrower requests be converted or continued, (ii) whether
such Borrowing is to be converted to or continued as a Eurodollar Borrowing, an
ABR Borrowing, a B/A Borrowing or a Canadian Prime Rate Borrowing, (iii) if such
notice requests a conversion, the date of such conversion (which shall be a
Business Day) and (iv) if such Borrowing is to be converted to or continued as a
Eurodollar Borrowing or a B/A Borrowing, the Interest Period or Contract Period,
respectively, with respect thereto. If no Interest Period or Contract Period is
specified in any such notice with respect to any conversion to or continuation
as a Eurodollar Borrowing or B/A Borrowing, respectively, the applicable
Borrower shall be deemed to have selected an Interest Period or Contract Period
of one month's or 30 days', as the case may be, duration. The Administrative
Agent shall advise the other Lenders of any notice given pursuant to this
Section 2.10 and of each Lender's portion of any converted or continued
------------
Borrowing. If the applicable Borrower shall not have given notice in accordance
with this Section 2.10 to continue any Borrowing into a subsequent Interest
          ------------
Period or Contract Period (and shall not otherwise have given notice in
accordance with this Section 2.10 to convert such Borrowing), such Borrowing
                     ------------
shall, at the end of the Interest Period applicable thereto (unless repaid
pursuant to the terms hereof), automatically be continued into a new Interest
Period as an ABR Borrowing or a Canadian Prime Rate Borrowing, as applicable.

shall pay or prepay so much of the then-outstanding Revolving Credit Borrowings

Borrowers shall prepay outstanding Loans in accordance with Section 2.13(f) in

Flow that is in excess of U.S.$100,000,000 for the fiscal year then ended.

         (d) Subject to Section 2.13(j), in the event that either Borrower or
                        ---------------
any Subsidiary shall receive Net Cash Proceeds from the issuance or other
disposition of Indebtedness for money borrowed of either Borrower or any
Subsidiary (other than Indebtedness for money borrowed permitted pursuant to
Section 7.01), the Borrowers shall substantially simultaneously with (and in any
event not later than the third Business Day next following) the receipt of such
Net Cash Proceeds by either Borrower or any Subsidiary, apply an amount equal to
100% of such Net Cash Proceeds to prepay outstanding Loans in accordance with
Section 2.13(f).

         (e) If on any date, as a result of fluctuations in the Exchange Rate,
the Administrative Agent determines that the aggregate Revolving Credit
Utilization shall have exceeded for more than three consecutive Business Days an
amount equal to 105% of the total Revolving Credit Commitments, the
Administrative Agent shall notify Canco of such occurrence and Canco shall on
the next succeeding Business Day prepay Revolving Credit Loans is an amount

(b), (c) or (d) above, a certificate signed by a Financial Officer of such
---  ---    ---
Borrower setting forth in reasonable detail the calculation of the amount of

prepayment required under this Section 2.13, a notice of such prepayment. Each

notice of prepayment shall specify the prepayment date, the Class and Type of
each Loan being prepaid and the principal amount of each Loan (or portion

         (h) To the extent possible consistent with paragraph (f) above, amounts

to be applied pursuant to this Section 2.13 to the prepayment of Loans shall be
                               ------------
applied first to reduce outstanding ABR Loans and, if applicable, Canadian Prime
Rate Loans. Any amounts remaining after each such application shall, at the
option of the applicable Borrower, be applied to prepay Eurodollar Loans
immediately and/or shall be deposited in the Prepayment Account (as defined
below). The Administrative Agent shall apply any cash deposited in the
Prepayment Account (i) allocable to Term Loans to prepay Eurodollar Term Loans
and (ii) allocable to Revolving Loans to prepay Eurodollar Revolving Loans, in
each case on the last day of their respective Interest Periods (or, at the
direction of the applicable Borrower, on any earlier date) until all outstanding
Term Loans or Revolving Loans, as the case may be, have been prepaid or until
all the allocable cash on deposit with respect to such Loans has been exhausted.
For purposes of this Agreement, the term "Prepayment Account" shall mean an

account established by the applicable Borrower with the Administrative Agent and
over which the Administrative Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal for application in accordance with
this paragraph (h). The Administrative Agent will, at the request of the
     -------------
Borrowers, invest amounts on deposit in the Prepayment Account in Permitted
Investments that mature prior to the last day of the applicable Interest Periods
of the Eurodollar Borrowings to be prepaid; provided, however, that (i) the
                                            --------  -------
Administrative Agent shall not be required to make any investment that, in its
sole judgment, would require or cause the Administrative Agent to be in, or
would result in any, violation of any law, statute, rule or regulation and (ii)
the Administrative Agent shall have no obligation to invest amounts on deposit
in the Prepayment Account if a Default or Event of Default shall have occurred
and be continuing. The Borrowers shall indemnify the Administrative Agent for
any losses relating to the investments so that the amount available to prepay
Eurodollar Borrowings on the last day of the applicable Interest Period is not
less than the amount that would have been available had no investments been made
pursuant thereto. Other than any interest earned on such investments, the
Prepayment Account shall not bear interest. Interest or profits, if any, on such
investments shall be deposited in the Prepayment Account and reinvested and
disbursed as specified above. If the maturity of the Loans has been accelerated
pursuant to Article VIII, the Administrative Agent may, in its sole discretion,
            ------------
apply all amounts on deposit in the Prepayment Account to satisfy any of the
Obligations. Each Borrower hereby grants to the Administrative Agent, for its
benefit and the benefit of the Facing Agent and the Lenders, a security interest
in the Prepayment Account to secure the Obligations.

than 20 Business Days prior to the date specified therein for such prepayment
(the "Mandatory Prepayment Date"), provide to each Lender a written notice
      -------------------------

applicable Lender (each, a "Prepayment Lender") will be entitled to receive if

it accepts such mandatory prepayment in accordance with this paragraph (i), (ii)
                                                             -------------
request such Prepayment Lender to notify the Borrowers and the Administrative
Agent in writing no later than the Business Day prior to the Mandatory
Prepayment Date of such Prepayment Lender's acceptance or rejection (in each
case, in whole and not in part) of its share of the Prepayment Amount and (iii)
inform such Prepayment Lender that failure by such Prepayment Lender to accept
in writing its share of the Prepayment Amount on or before the Business Day
prior to the Mandatory Prepayment Date shall be deemed a rejection of such
amount. On the Mandatory Prepayment Date, the Borrowers shall apply the
aggregate amount necessary to prepay that portion of the Prepayment Amount in
respect of which such Prepayment Lenders have accepted prepayment as described
above (such Prepayment Lenders, the "Accepting Lenders") pro rata against the
                                     -----------------
remaining installments of principal due in respect of the Term Loans of the
Accepting Lenders under Section 2.11(a). So long as no Default or Event of
                        ---------------
Default shall have occurred and be continuing, the Borrowers shall apply any
remaining portion of the Prepayment Amount to the repayment of Indebtedness
maturing prior to the Term Loan Maturity Date. In the event that any provision
of this Section 2.13 requires prepayment of the Term Loans prior to the selected
        ------------
Mandatory Prepayment Date, the Borrowers shall deposit the entire amount of the
Prepayment Amount into an account under the exclusive control and dominion of
the Administrative Agent.

         (j)  Notwithstanding anything to the contrary contained in this
Agreement, no prepayments are required to be made with respect to the Tranche H
Loans under Section 2.11(a)(ii) or Section 2.13(c) or (d) to the extent that
            ------------------     --------------     ---
such prepayment or the obligation to make such prepayment would result in Canco
under any circumstances being obliged to pay more than 25% of the original
principal amount of the Tranche H Loans (the "Threshold Amount") prior to the
                                              ----------------
fifth anniversary of the Closing Date. The amount of such prepayments in excess
of the Threshold Amount (the "Excess Amount") will be allocated to the further
                              -------------
prepayment of the Tranche G Loans and allocated pro rata against the remaining
scheduled installments of principal due in respect of the Tranche G Loans under
Section 2.11(a)(i) until the Tranche G Loans have been paid in full. On the
------------------
Business Day immediately after the fifth anniversary of the Closing Date, the
Excess Amount not allocated to the further payment of the Tranche G Loans will
be paid to the Tranche H Lenders and allocated pro rata against the remaining
scheduled installments of principal due in respect of the Tranche H Loans under
Section 2.11(a)(ii).

         SECTION 2.14. Reserve Requirements; Change in Circumstances; Increased
Costs. (a) Notwithstanding any other provision herein, if after the Closing Date
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law)

                                                                              48

shall change the basis of taxation of payments to any Lender or the Facing
Agent of the principal of or interest on any Loan made by such Lender or any
Letter of Credit obligations, Fees or other amounts payable hereunder (other
than changes in respect of income and franchise taxes imposed on such Lender or
the Facing Agent by the jurisdiction in which such Lender or the Facing Agent is
organized or has its principal or lending office or by any political subdivision
or taxing authority thereof or therein), or shall 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 such Lender or the
Facing Agent (except any such reserve requirement that is reflected in the
Adjusted LIBO Rate, the Alternate Base Rate or the Canadian Prime Rate) or shall
impose on such Lender or the Facing Agent or the London or Canadian interbank
market any other condition affecting this Agreement or Loans made by such
Lender, and the result of any of the foregoing shall be to increase the cost to
such Lender of making or maintaining any Loan or to reduce the amount of any sum
received or receivable by such Lender or the Facing Agent hereunder (whether of
principal, interest or otherwise) by an amount deemed by such Lender or the
Facing Agent to be material, then the applicable Borrower will pay to such
Lender or the Facing Agent following receipt by such Borrower of a certificate
of such Lender or the Facing Agent to such effect in accordance with Section
                                                                     -------
2.14(c) such additional amount or amounts as will compensate such Lender or the
-------
Facing Agent on an after-tax basis for such additional costs incurred or
reduction suffered; provided, however, that no Lender or the Facing Agent shall
                    --------  -------
be entitled to demand compensation pursuant to this paragraph (a) if it shall
                                                    -------------
not be the general practice of such Lender or the Facing Agent, as applicable,
to demand such compensation in similar circumstances under comparable provisions
of other comparable credit agreements.

         (b) If any Lender or the Facing Agent shall have determined that the
adoption after the Closing Date of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or the Facing Agent or any Lender's or the Facing
Agent's holding company, if any, with any request or directive regarding capital
adequacy issued under any law, rule, regulation or guideline (whether or not
having the force of law) of any such Governmental Authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on such Lender's or the Facing Agent's capital or on the capital of such
Lender's or the Facing Agent's holding company, if any, as a consequence of this
Agreement or the Loans made by such Lender or the Letters of Credit issued by
the Facing Agent pursuant hereto to a level below that which such Lender or the
Facing Agent or such Lender's or the Facing Agent's holding company, if any,
could have achieved but for such applicability, adoption, change or compliance
(taking into consideration such Lender's or the Facing Agent's policies and the
policies of such Lender's or the Facing Agent's holding company, if any, with
respect to capital adequacy) by an amount deemed by such Lender or the Facing
Agent to be material, then from time to time the applicable Borrower shall pay
to such Lender or the Facing Agent following receipt by such Borrower of a
certificate of such Lender or the Facing Agent to such effect in accordance with
Section 2.14(c) such additional amount or amounts as will compensate such Lender
---------------
or the Facing Agent or such Lender's or the Facing Agent's holding company, if
any, on an after-tax basis for any such reduction suffered; provided, however,
                                                            --------  -------
that no Lender or the Facing

Agent shall be entitled to demand compensation pursuant to this paragraph (b) if
                                                                ---------
it shall not be the general practice of such Lender or the Facing Agent, as
applicable, to demand such compensation in similar circumstances under
comparable provisions of other comparable credit agreements.

         (c) A certificate of each Lender or the Facing Agent setting forth such
amount or amounts as shall be necessary to compensate such Lender or the Facing
Agent or its holding company, if any, as specified in paragraph (a) or (b)
                                                      -------------    ---
above, as the case may be, and setting forth in reasonable detail an explanation
of the basis of requesting such compensation in accordance with paragraph (a) or
                                                                -------------
(b) above, including calculations in reasonable detail, shall be delivered to
---
the applicable Borrower and shall be conclusive absent manifest error. The
applicable Borrower shall pay each Lender or the Facing Agent the amount shown
as due on any such certificate delivered by it within 10 days after its receipt
of the same.

         (d)  Failure on the part of any Lender or the Facing Agent to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital with respect to any period shall
not constitute a waiver of such Lender's or the Facing Agent's right to demand
compensation with respect to such period or any other period, except that no
Lender or the Facing Agent shall be entitled to compensation under this Section
                                                                        -------
2.14 for any costs incurred or reduction suffered with respect to any date
----
unless such Lender or the Facing Agent, as applicable, shall have notified the
applicable Borrower that it will demand compensation for such costs or
reductions under paragraph (c) above, not more than six months after the later
                 -------------
of (i) such date and (ii) the date on which such Lender or the Facing Agent, as
applicable, shall have become aware of such costs or reductions. The protection
of this Section 2.14 shall be available to each Lender or the Facing Agent
        ------------
regardless of any possible contention of the invalidity or inapplicability of
the law, rule, regulation, guideline or other change or condition that shall
have occurred or been imposed.

         SECTION 2.15. Change in Legality. (a) Notwithstanding any other
provision herein, if after the Closing Date any change in any law or regulation
or in the interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or Revolving Loan denominated in U.S.
Dollars or to give effect to its obligations as contemplated hereby with respect
to any Eurodollar Loan or Revolving Loan denominated in U.S. Dollars, then, by
written notice to the applicable Borrower and to the Administrative Agent, such
Lender may:

                  (i)  declare that Eurodollar Loans or Revolving Loans
         denominated in U.S. Dollars will not thereafter be made by such Lender
         hereunder, whereupon any request by the applicable Borrower for a
         Eurodollar Revolving Credit Borrowing or a Borrowing denominated in
         U.S. Dollars shall, as to such Lender only, be deemed a request for an
         ABR Loan or a Revolving Loan denominated in Canadian Dollars,
         respectively, unless such declaration shall be subsequently withdrawn;
         and

                  (ii) require that all outstanding Eurodollar Loans or
         Revolving Loans denominated in U.S. Dollars made by it be converted to
         ABR Loans or Revolving Loans denominated in Canadian Dollars,
         respectively, in which event all such Eurodollar Loans or Revolving
         Loans
<PAGE>

                                                                              50

         denominated in U.S. Dollars, as the case may be, shall be automatically
         converted to ABR Loans and Revolving Loans denominated in Canadian
         Dollars, respectively, as of the effective date of such notice as
         provided in paragraph (b) below.
                     -------------

In the event any Lender shall exercise its rights under clause (i) or (ii)
                                                        ----------    ----
above, all payments and prepayments of principal that would otherwise have been
applied to repay the Eurodollar Loans or the Revolving Loans denominated in U.S.
Dollars that would have been made by such Lender or the converted Eurodollar
Loans or Revolving Loans denominated in U.S. Dollars of such Lender shall
instead be applied to repay the ABR Loans or Revolving Loans denominated in
Canadian Dollars made by such Lender in lieu of, or resulting from the
conversion of, such Eurodollar Loans or Revolving Loans denominated in U.S.
Dollars, as the case may be.

         (b) For purposes of this Section 2.15, a notice to the applicable
                                  -------------
Borrower by any Lender shall be effective as to each Eurodollar Loan or
Revolving Loan denominated in U. S. Dollars if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan or Revolving Loan
denominated in U. S. Dollars, as the case may be; in all other cases, such
notice shall be effective on the date of receipt by such Borrower.

         SECTION 2.16.  Indemnity. Each Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur with respect
to Eurodollar Loans as a consequence of (a) any failure by any Borrower to
fulfill on the date of any Borrowing hereunder the applicable conditions set
forth in Article V, (b) any failure by such Borrower to borrow or to refinance,
         ---------
convert or continue any Loan hereunder after irrevocable notice of such
borrowing, refinancing, conversion or continuation has been given pursuant to
Section 2.03 or 2.10, (c) any payment, prepayment or conversion of a Eurodollar
------------    ----
Loan or B/A Loan required or permitted by any other provision of this Agreement
or otherwise, or any assignment of a Eurodollar Loan or B/A Loan required by
Section 2.21(b), in each case made or deemed made on a date other than the last
---------------
day of the Interest Period or Contract Period, as the case may be, applicable
thereto, (d) any purchase of a participation pursuant to Article X of a
                                                         ----------
Eurodollar Loan or a B/A Loan of such Borrower otherwise made or deemed made on
a date other than the last day of the Interest Period or Contract Period
therefor, or (e) any default in payment or prepayment of the principal amount of
any Loan or any part thereof or interest accrued thereon, as and when due and
payable (at the due date thereof, whether at scheduled maturity, by
acceleration, irrevocable notice of prepayment or otherwise), including, in each
such case, any loss or reasonable expense sustained or incurred or to be
sustained or incurred in liquidating or employing deposits from third parties
acquired to effect or maintain such Loan or any part thereof as a Eurodollar
Loan or B/A Loan, as the case may be. Such loss or reasonable expense shall be
equal to the sum of (a) such Lender's actual costs and expenses incurred (other
than any lost profits) in connection with, or by reason of, any of the foregoing
events and (b) an amount equal to the excess, if any, as reasonably determined
by such Lender of (i) its cost of obtaining the funds for the Loan being paid,
prepaid, converted or not borrowed, converted or continued (assumed to be the
Adjusted LIBO Rate or the Discount Rate, as applicable, applicable thereto) for
the period from and including the date of such payment, prepayment, conversion
or failure to borrow, convert or continue to but excluding the last day of the
Interest Period or Contract Period, as the case may be for such Loan (or, in the
case of a failure to borrow, convert or continue, the Interest Period for such
Loan
<PAGE>

                                                                              51

that would have commenced on the date of such failure) over (ii) the amount of
interest (as reasonably determined by such Lender) that would be realized by
such Lender in reemploying the funds so paid, prepaid, converted or not
borrowed, converted or continued for such period, Interest Period or Contract
Period, as the case may be. A certificate of any Lender setting forth any amount
or amounts, including calculations in reasonable detail, that such Lender is
entitled to receive pursuant to this Section 2.16 shall be delivered to the
                                     ------------
applicable Borrower and shall be conclusive absent manifest error.

         SECTION 2.17. Pro Rata Treatment. Except as required under Section 2.15
                                                                    ------------
or permitted under Section 2.13(h), each Borrowing, each payment or prepayment
                   ---------------
of principal of any Borrowing, each payment of interest on the Loans, each
payment of the Commitment Fees, each payment of the LC Participation Fees, each
reduction of the Commitments and each refinancing of any Borrowing with,
conversion of any Borrowing to or continuation of any Borrowing as a Borrowing
of any Type shall be allocated pro rata among the Lenders in accordance with
their respective applicable Commitments (provided that in the event that such
                                         --------
Commitments shall have expired or been terminated, such pro rata allocation
shall be based on the respective principal amounts of the outstanding Loans).
Each Lender agrees that in computing such Lender's portion of any Borrowing to
be made hereunder, the Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing, computed in accordance with Section 2.01,
                                                                   ------------
to the next higher or lower whole U.S. Dollar or Canadian Dollar amount, as
applicable. In addition, each Lender agrees that the Administrative Agent may,
in its sole discretion, increase or reduce any Revolving Lender's portion of a
B/A Loan to the extent provided in Section 2.22(e).

         SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
any Loan Party, or pursuant to a secured claim under any applicable Insolvency
Law or other security or interest arising from, or in lieu of, such secured
claim, received by such Lender under any applicable Insolvency Law or otherwise,
or by any other means, obtain payment (voluntary or involuntary) in respect of
any Loan or Loans or LC Exposure as a result of which the unpaid principal
portion of its Loans or its LC Exposure shall be proportionately less than the
unpaid principal portion of the Loans of any other Lender or any other Lender's
LC Exposure, such Lender shall be deemed simultaneously to have purchased from
such other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Loans of such other Lender or the LC
Exposure of such other Lender, so that the aggregate unpaid principal amount of
the Loans, LC Exposure and participation in Loans and LC Exposure held by each
Lender shall be in the same proportion to the aggregate unpaid principal amount
of all Loans and LC Exposure then outstanding as the principal amount of such
Lender's Loans and LC Exposure prior to such exercise of banker's lien, setoff
or counterclaim or other event was to the principal amount of all Loans and LC
Exposure outstanding prior to such exercise of banker's lien, setoff or
counterclaim or other event; provided, however, that if any such purchase or
                             --------  -------
purchases or adjustments shall be made pursuant to this Section 2.18 and the
                                                        ------------
payment giving rise thereto shall thereafter be recovered, such purchase or
purchases or adjustments shall be rescinded to the extent of such recovery and
the purchase price or prices or adjustment restored without interest. Each
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding a participation in a Loan or LC Exposure deemed to have been so
purchased may

                                                                              52

exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Loan Parties to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to the applicable
Borrower in the amount of such participation.

         SECTION 2.19. Payments. (a) Each Borrower shall make each payment
(including principal of or interest on any Loan or any Fees or other amounts)
hereunder and under any other Loan Document not later than 12:00 noon, Standard
Time, on the date when due in immediately available U.S. Dollars or Canadian
Dollars, as applicable, without defense, setoff or counterclaim. Each such
payment (other than (i) the payments specified in Sections 2.05(c)(ii) and (iii)
                                                  --------------------     -----
and paragraph (d) of Article III, which shall be paid directly to the Facing
    -------------    -----------
Agent) shall be made to such account of the Administrative Agent or the Canadian
Administrative Agent, as applicable, as such Agent shall specify by notice to
the applicable Borrower. Payments made directly to the Facing Agent shall be
made to such account of the Facing Agent as the Facing Agent shall specify by
notice to Canco. Any payments received by the Administrative Agent, the Canadian
Administrative Agent or the Facing Agent after the specified time for receipt of
such payment on any day shall be deemed to have been received on the next
Business Day. The Administrative Agent or the Canadian Administrative Agent, as
applicable, shall distribute to the applicable Lenders all payments received by
it for their respective accounts, promptly following receipt thereof.

         (b)  Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by the Loan Parties
hereunder shall be made, in accordance with Section 2.19, free and clear of and
                                            ------------
without deduction for any and all current or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding taxes imposed on the net income of the Administrative Agent or the
---------
Facing Agent or any Lender (or any transferee or assignee thereof, including a
participation holder (any such entity being called a "Transferee")), and
                                                      ----------
franchise taxes imposed on the Administrative Agent or the Facing Agent or any
Lender (or Transferee), by the United States, Canada or any jurisdiction under
the laws of which the Administrative Agent or the Facing Agent or any such
Lender (or Transferee) is organized or in which the Administrative Agent or the
Facing Agent or any such Lender (or Transferee) has its principal office or
lending office or any political subdivision or taxing authority thereof or
therein (all such nonexcluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "Taxes"). If any
                                                               -----
Taxes are required to be deducted from or in respect of any sum payable
hereunder to any Lender (or any Transferee), the Administrative Agent or the
Facing Agent, (i) the sum payable shall be increased by the amount necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.20) such Lender (or Transferee),
                                   ------------
the Administrative Agent or the Facing Agent (as the case may be) shall receive
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Borrowers shall make such deductions and (iii) the Borrowers
shall pay the full amount deducted to the relevant taxing authority or other
Governmental Authority in
<PAGE>

                                                                              53

accordance with applicable law; provided, however, that no Transferee of any
                                --------  -------
Lender shall be entitled to receive any greater payment under this paragraph (a)
                                                                   -------------
than such Lender would have been entitled to receive with respect to the rights
assigned, participated or otherwise transferred unless (x) such assignment,
participation or transfer shall have been made at a time when the circumstances
(including a Change of Law) giving rise to such greater payment did not exist or
had not yet occurred, (y) such assignment, participation or transfer shall have
been at the request of the Borrowers or (z) such assignment, participation or
transfer shall have been made pursuant to Section 2.18 or Article X.
                                          ------------    ---------

         (b) Each Borrower agrees to pay any current or future stamp, intangible
or documentary taxes or any other excise or property taxes, charges or similar
levies (including, without limitation, mortgage recording taxes and similar
fees) that arise from any payment made hereunder or from the execution, delivery
or registration of, or otherwise with respect to, this Agreement, any Assignment
and Acceptance entered into at the request of either Borrower or any other Loan
Document (hereinafter referred to as "Other Taxes").
                                      -----------

         (c) Each Borrower will indemnify each Lender (or Transferee), the
Administrative Agent and the Facing Agent for the full amount of Taxes and Other
Taxes (including any Taxes or Other Taxes on amounts payable under this Section
                                                                        -------
2.20) paid by such Lender (or Transferee), the Administrative Agent or the
----
Facing Agent, as the case may be, and any liability (including penalties,
interest and reasonable expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant taxing authority or other Governmental Authority. Such
indemnification shall be made within 30 days after the date any Lender (or
Transferee), the Administrative Agent or the Facing Agent, as the case may be,
makes written demand therefor (which demand shall identify the nature and amount
of Taxes and Other Taxes for which indemnification is being sought and shall
include a copy of the relevant portion of any written assessment from the
relevant taxing authority demanding payment of such Taxes or Other Taxes, unless
the Lender (or Transferee), the Administrative Agent or the Facing Agent, as the
case may be, determines, in its sole discretion, that such portion of any such
assessment is confidential). If a Lender (or Transferee), the Administrative
Agent or the Facing Agent shall become aware that it is entitled to receive a
refund in respect of Taxes or Other Taxes as to which it has been indemnified by
the applicable Borrower pursuant to this Section 2.20, it shall promptly notify
                                         ------------
such Borrower of the availability of such refund and shall, within 30 days after
receipt of a request by the applicable Borrower, apply for such refund at such
Borrower's expense. If any Lender (or Transferee), the Administrative Agent or

it shall promptly notify such Borrower of such refund and shall, within 30 days

such Borrower under this Section 2.20 with respect to such refund and not

previously reimbursed) to such Borrower, net of all reasonable out-of-pocket
expenses of such Lender, the Administrative Agent or the Facing Agent and

event such Lender (or Transferee), the Administrative Agent or the Facing Agent
is required to repay such refund.

     (d) Within 30 days after the date of any payment of Taxes or Other Taxes
withheld by either Borrower in respect of any payment to any Lender (or
Transferee), the Administrative Agent or the Facing Agent, such Borrower will
furnish to the Administrative Agent, at the addresses referred to in Section

herein, the agreements and obligations contained in this Section 2.20 shall
                                                         ------------
survive the payment in full of the principal of and interest on all Loans made
hereunder.

Lender (or Transferee thereof) that is not incorporated or otherwise formed
under the laws of the United States of America or a state thereof (a "Non-U.S.
                                                                      --------

the Administrative Agent or the Facing Agent hereunder, deliver to Stone and the
Administrative Agent (x) one duly completed copy of United States Internal
Revenue Service Form 1001 or 4224 (or replacement or successor forms thereto),
or (y) in the case of Tranche G Lenders (or Transferees thereof) exempt from
United States Federal withholding tax pursuant to Sections 871(h) or 881(c) of
the Code, one duly completed copy of a United States Internal Revenue Service
Form W-8 (or successor form) (including Form W-8BEN (Certificate of Foreign
Status of Beneficial Owner for United States Tax Withholding) and Form W-8ECI
(Certificate of Foreign Person's Claim for Exemption From Withholding or Income
Effectively Connected with the Conduct of a Trade or Business in the United
States)) and a certificate representing that such Non-U.S. Person is not a bank
for purposes of Section 881(c) of the Code, or any successor applicable form of
any thereof, certifying in each case that such Tranche G Lender (or Transferee
thereof), the Administrative Agent or the Facing Agent is entitled to receive
payments hereunder payable to it without deduction or withholding of any United
States Federal income taxes, or subject to a reduced rate thereof. Each of the
Administrative Agent or the Facing Agent or any Tranche G Lender (or Transferee
thereof) that delivers to Stone and the Administrative Agent any such form or
certification further undertakes to deliver to Stone and the Administrative
Agent further copies of any such form or certification or other manner of
certification reasonably satisfactory to Stone on or before the date that any
such form or certification expires or becomes obsolete or of the occurrence of
any event requiring a change in the most recent forms or certifications
previously delivered by it to Stone or the Administrative Agent, and such
extensions or renewals thereof as may reasonably be requested by Stone or the
Administrative Agent, certifying that the Administrative Agent, Facing Agent or
such Tranche G Lender (or Transferee thereof), as the case may be, is entitled
to receive payments hereunder without deduction or withholding of any United
States Federal income taxes, or subject to a reduced rate thereof. If at any
time there has occurred, on or prior to the date on which any delivery of any
such form or certification would otherwise be required, any change in law, rule,
regulation, treaty, convention or directive, or any change in the interpretation
or application of any thereof ("Change of Law"), that renders all such forms or

prevent the Administrative Agent, Facing Agent or such Tranche G Lender (or
Transferee thereof), as the case may be, from duly completing and delivering any
such form or certification with respect to it, the Administrative Agent, Facing
Agent or such Tranche G Lender (or Transferee thereof), as the case may be,
shall advise Stone that under applicable law it shall be subject to withholding
of United States Federal income tax at the full statutory rate, a reduced rate
of withholding or without deduction or withholding. A Non-U.S. Person shall be
required to furnish any such form or certification only if it is entitled to
claim an exemption from, or a reduced rate of, withholding. Each of the
Administrative Agent, the Facing Agent and any Tranche G Lender that is a Non-
U.S. Person and that is a party hereto as of the Closing Date hereby represents
and warrants that, as of the Closing Date, all payments made to it hereunder are
exempt from withholding of United States Federal income taxes (x) because such
payments are effectively connected with a United States trade or business
conducted by such Non-U.S. Person; (y) pursuant to the terms of an income tax
treaty between the United States and such Non-U.S. Person's country of
residence; or (z) because such payments are portfolio interest exempt pursuant
to Section 871(h) or 881(c) of the Code. Notwithstanding any provision of
paragraph (a) above to the contrary, Stone shall not have any obligation to pay
-------------
any Taxes or Other Taxes or to indemnify any Tranche G Lender (or Transferee
thereof), the Administrative Agent or the Facing Agent for such Taxes or Other
Taxes pursuant to this Section 2.20 to the extent that such Taxes or Other Taxes
                       ------------
result from (x) the failure of any Tranche G Lender (or Transferee thereof), the
Administrative Agent or the Facing Agent to comply with its obligations pursuant
to this paragraph (f) or (y) any representation made on any such form or
        -------------
certification (or successor applicable form or certification) by the Tranche G
Lender (or Transferee thereof), the Administrative Agent or the Facing Agent
incurring such Taxes or Other Taxes proving to have been incorrect, false or
misleading in any material respect when so made or deemed to be made. Nothing
contained herein shall require the Administrative Agent, the Facing Agent or any
Tranche G Lender (or Transferee thereof) to make its tax returns (or any other
information relating to its taxes which it deems confidential) available to
Stone or any other person.

     (g) Each of the Administrative Agent, the Facing Agent, and any Tranche H
Lender (or Transferee thereof) that is entitled to an exemption from or
reduction of withholding tax under the laws of Canada, or any treaty to which
Canada is a party, with respect to payment in connection with the Tranche H
Loans under this Agreement shall, upon request by the Administrative Agent,
deliver to Canco (with a copy to the Administrative Agent), such properly
completed and executed documentation prescribed by applicable law or reasonably
requested by Canco as will permit such payments to be made without withholding
or at a reduced rate. Notwithstanding any provision of paragraph (a) above to
                                                       -------------
the contrary, Canco shall have no obligation to pay any Taxes or Other Taxes or
to indemnify any Tranche H Lender or Revolving Lender (or Transferee thereof),
the Administrative Agent or the Facing Agent for such Taxes or Other Taxes
pursuant to this Section 2.20 to the extent that such Taxes or Other Taxes
                 ------------
result from (x) the failure of any Tranche H Lender or Revolving Lender, the
Administrative Agent or the Facing Agent to comply with its obligations pursuant
to this paragraph (g) (provided, however, that no Tranche H Lender shall be
        -------------  --------  -------
required to provide any documentation that it is not legally able to provide) or
(y) any representation made in any such documentation by the Tranche H Lender,
Revolving Lender, the Administrative Agent or the Facing Agent incurring such
Taxes or Other Taxes proving to have been incorrect, false or misleading in any
material respect when so made or deemed to be made. Nothing contained herein

shall require the Administrative Agent, the Facing Agent or any Tranche H Lender
or Revolving Lender (or Transferee thereof) to make its tax returns (or any
other information relating to its taxes which it deems confidential) available
to Canco or any other Person.

     SECTION 2.21. Duty to Mitigate; Assignment of Commitments under Certain
Circumstances. (a) Any of the Administrative Agent, the Facing Agent or any
Lender (or Transferee) claiming any additional amounts payable pursuant to
Section 2.14 or Section 2.20 or exercising its rights under Section 2.15 shall
------------    ------------                                ------------
use reasonable efforts (consistent with legal and regulatory restrictions) to
file any certificate or document requested by either Borrower or to change the
jurisdiction of its applicable lending office if the making of such filing or
change would avoid the need for or reduce the amount of any such additional
amounts that may thereafter accrue or avoid the circumstances giving rise to
such exercise and would not, in the sole determination of such Lender (or
Transferee), the Administrative Agent or the Facing Agent, as the case may be,
require it to incur additional costs or be otherwise disadvantageous to such
Lender (or Transferee), the Administrative Agent or the Facing Agent.

     (b)  In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.14 or 2.15, or either Borrower shall be
                        ------------    ----
required to make additional payments to any Lender under Section 2.20, the
                                                         ------------
applicable Borrower shall have the right, but not the obligation, at its own
expense (including with respect to the processing and recordation fee referred
to in Section 11.04(b)), upon notice to such Lender and the Administrative
      -----------------
Agent, to replace such Lender with an assignee (in accordance with and subject
to the restrictions contained in Section 11.04(b)) approved by the
Administrative Agent (which approval shall not be unreasonably withheld), and
such Lender hereby agrees to transfer and assign without recourse (in accordance
with and subject to the restrictions contained in Section 11.04(b)) all its
                                                  -----------------
interests, rights and obligations under this Agreement to such assignee;
provided, however, that no Lender shall be obligated to make any such assignment
--------  -------
unless (i) such assignment shall not conflict with any law or any rule,
regulation or order of any Governmental Authority, (ii) such assignee shall pay
to the affected Lender in immediately available funds on the date of such
assignment the principal of the Loans made by such Lender hereunder and (iii)
the applicable Borrower shall pay to the affected Lender in immediately
available funds on the date of such assignment the interest accrued to the date
of payment on the Loans made by such Lender hereunder and all other amounts
accrued for such Lender's account or owed to it hereunder.

     (c)  If, in connection with any proposed amendment, modification, change,
waiver, discharge or termination to any of the provisions of this Agreement as
contemplated by Section 11.08(b), the consent of the Required Lenders is
                ----------------
obtained but the consent of one or more of such other Lenders whose consent is
required is not obtained, then the Borrower shall have the right, but not the
obligation, at its own expense (including with respect to the processing and
recordation fee referred to in Section 11.04(b)) upon notice to such Lender and
                               -----------------
the Administrative Agent, so long as all non-consenting Lenders whose individual
consent is required are treated as described below, to replace each such non-
consenting Lender or Lenders (or, at the option of the Borrower if the
respective Lender's consent is required with respect to less than all Loans, to
replace only the respective Loans of the respective non-consenting Lender which
gave rise to the need to obtain such Lender's individual consent) with an
assignee (in accordance with and subject to the restrictions contained in

                                                                              57

Section 11.04(b)) approved by the Administrative Agent (which approval shall not
be unreasonably withheld) so long as at the time of such replacement, each such
assignee consents to the proposed amendment, modification, change, waiver,
discharge or termination; provided, however, that no Lender shall be obligated
to make any such assignment unless (i) such assignment shall not conflict with
any law or any rule, regulation or order of any Governmental Authority, (ii)
such assignee shall pay to the non-consenting Lender in immediately available
funds on the date of such assignment the principal of the Loans made by such
Lender hereunder and subject to such assignment and (iii) the Borrower shall pay
to the non-consenting Lender in immediately available funds on the date of such
assignment the interest accrued to the date of payment on the Loans made by such
Lender hereunder and subject to such assignment and all other amounts accrued
for such Lender's account or owed to it hereunder with respect to such Loans.

     SECTION 2.22.  Bankers' Acceptances. (a) Subject to the terms and
conditions of this Agreement, Canco may request a Revolving Credit Borrowing
denominated in Canadian Dollars by presenting drafts for acceptance and, if
applicable, purchase as B/A's by the Revolving Lenders.

     (b)  No Contract Period with respect to a B/A to be accepted and, if
applicable, purchased as a Revolving Loan shall extend beyond the Revolving
Credit Maturity Date. All B/A's and B/A Loans shall be denominated in Canadian
Dollars.

     (c)  To facilitate availment of B/A Loans, Canco hereby appoints each
Revolving Lender as its attorney to sign and endorse on its behalf (in
accordance with a notice of Borrowing relating to a B/A Loan pursuant to Section
2.03 or Section 2.10), in handwriting or by facsimile or mechanical signature as
and when deemed necessary by such Revolving Lender, blank forms of B/A's in the
form requested by such Revolving Lender. In this respect, it is each Revolving
Lender's responsibility to maintain an adequate supply of blank forms of B/A's
for acceptance under this Agreement. Canco recognizes and agrees that all B/A's
signed and/or endorsed by a Revolving Lender on behalf of Canco shall bind Canco
as fully and effectually as if signed in the handwriting of and duly issued by
the proper signing officers of Canco. Each Revolving Lender is hereby authorized
(in accordance with a notice of Borrowing relating to a B/A Loan) to issue such
B/A's endorsed in blank in such face amounts as may be determined by such
Revolving Lender; provided that the aggregate amount thereof is equal to the
aggregate amount of B/A's required to be accepted and purchased by such
Revolving Lender. No 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 for the gross negligence or wilful misconduct of the Revolving Lender or
its officers, employees, agents or representatives. Each Revolving Lender shall
maintain a record, which shall be made available to Canco upon its request, with
respect to B/A's (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. On request by or on behalf of Canco, a Revolving
Lender shall cancel all forms of B/A's which have been pre-signed or pre-
endorsed on behalf of Canco and that are held by such Revolving Lender and are
not required to be issued in accordance with Canco's irrevocable notice.
Alternatively, Canco agrees that, at the request of the Canadian Administrative
Agent, Canco shall deliver to the Canadian Administrative Agent a "depository
note" which complies with the requirements of the Depository Bills and Notes Act
(Canada), and consents to the deposit of any such depository note in the book-
based debt clearance system maintained by the Canadian Depository for
Securities.

     (d) Drafts of Canco to be accepted as B/A's hereunder shall be signed as
set forth in this Section 2.22. Notwithstanding that any Person whose signature
                  ------------
appears on any B/A may no longer be an authorized signatory for any Lender or
Canco 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
Canco.

     (e) Promptly following the receipt of a notice of borrowing specifying a
Revolving Credit Borrowing by way of B/A's, the Canadian Administrative Agent
shall so advise the Revolving Lenders and shall advise each Revolving Lender of
the aggregate face amount of the B/A's to be accepted by it and the applicable
Contract Period (which shall be identical for all Revolving Lenders). In the
case of Revolving Loans comprised of B/A Loans, the aggregate face amount of the
B/A's to be accepted by a Revolving Lender shall be in a minimum aggregate
amount of Cdn.$100,000 and shall be a whole multiple of Cdn.$100,000, and such
face amount shall be in the Revolving Lenders' pro rata portions of such
Revolving Borrowing, provided that the Administrative Agent may in its sole
                     --------
discretion increase or reduce any Revolving Lender's portion of such B/A Loan to
the nearest Cdn.$100,000 without reducing the aggregate Revolving Credit
Commitments.

     (f) Canco may specify in a notice of borrowing pursuant to Section 2.03 or
                                                                ------------
Section 2.10 that it desires that any B/A's requested by such notice of
------------
borrowing be purchased by the Revolving Lenders, in which case the Revolving
Lenders shall, upon acceptance of a B/A by a Revolving Lender, purchase, or
arrange for the purchase of, each B/A from Canco at the Discount Rate for such
Revolving Lender applicable to such B/A accepted by it and provide to the
Canadian Administrative Agent the Discount Proceeds for the account of Canco.
The Acceptance Fee payable by Canco to a Revolving Lender under Section 2.06(d)
                                                                ---------------
in respect of each B/A accepted by such Revolving Lender shall be set off
against the Discount Proceeds payable by such Revolving Lender under this
Section 2.22.
------------

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

     (h) If a Revolving Lender is not a chartered bank under the Bank Act
(Canada) or if a Revolving Lender notifies the Canadian Administrative Agent in
writing that it is otherwise unable to accept Bankers' Acceptances, such
Revolving Lender will, instead of accepting and, if applicable, purchasing
Bankers' Acceptances, make an advance (a "B/A Equivalent Loan") to Canco in the
                                          -------------------
amount and for the same term as the draft that such Revolving Lender would
otherwise have been required to accept and purchase hereunder. Each such
Revolving Lender will provide to the Canadian Administrative Agent the Discount
Proceeds of such B/A Equivalent Loan for the account of Canco. Each such B/A
Equivalent Loan will bear interest at the same rate that would result if such
Lender had accepted (and been paid an Acceptance Fee) and purchased (on a
discounted basis at the Discount Rate) a Bankers' Acceptance for the relevant
Contract Period (it being the intention of the parties that each such B/A
Equivalent Loan shall have the same economic consequences for the Lenders and
Canco as the Bankers' Acceptance which such B/A Equivalent Loan replaces). All
such interest shall be paid in advance on the date such B/A Equivalent Loan is
made, and will be deducted

                                                                              59

from the principal amount of such B/A Equivalent Loan in the same manner in
which the Discount Proceeds of a Bankers' Acceptance would be deducted from the
face amount of the Bankers' Acceptance.

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

     (j) Except as required by any Revolving Lender upon the occurrence of an
Event of Default, no B/A Loan may be repaid by Canco prior to the expiry date of
the Contract Period applicable to such B/A Loan; provided, however, that any B/A
                                                 --------  -------
Loan may be defeased as provided in the proviso to Section 2.12(a).

                               Letters of Credit

     Subject to the terms and conditions set forth herein, Canco may request the
issuance of Letters of Credit denominated in U.S. Dollars or Canadian Dollars
for its own account, in a form reasonably acceptable to the Administrative Agent
and the Facing Agent, at any time and from time to time prior to the date that
is 30 days before the Revolving Credit 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 Canco to, or entered into by Canco with, the Facing Agent relating
to any Letter of Credit, the terms and conditions of this Agreement shall
control. Each Letter of Credit is subject to the following terms and conditions:

     (a)  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), Canco shall hand deliver or
telecopy (or transmit by electronic communication, if arrangements for doing so
have been approved by the Facing Agent) to the Facing Agent, the Administrative
Agent and the Canadian 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 (b) of this
                                                       -------------
Article III), the amount and currency 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 Facing Agent, Canco also shall submit a letter of credit application on
the Facing Agent'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
Canco 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 U.S.$50,000,000 and (ii) the Revolving Credit Utilization shall not
exceed the aggregate Revolving Credit Commitments.

     (b) Expiration Date. Each Letter of Credit shall expire at or prior to the
close of business on the earliest of (i) the date one year after the date of the
issuance of such Letter of Credit (or, in the case of any renewal or extension
thereof, one year after such renewal or extension) and (ii) the date that is 30
days prior to the Revolving Maturity Date.

     (c) 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 Facing Agent or the Lenders, the Facing Agent hereby
grants to each Revolving Lender, and each Revolving Lender hereby acquires from
the Facing Agent, a participation in such Letter of Credit equal to such
Lender's Applicable Percentage of the aggregate amount available to be drawn
under such Letter of Credit. In consideration and in furtherance of the
foregoing, each Revolving Lender hereby absolutely and unconditionally agrees to
pay to the Canadian Administrative Agent, for the account of the

                                                                              61

Facing Agent, such Lender's Applicable Percentage of each LC Disbursement made
by the Facing Agent and not reimbursed by Canco on the date due as provided in
paragraph (d) of this Article III, or of any reimbursement payment required to
-------------         -----------
be refunded to Canco for any reason. Each Lender acknowledges and agrees that
its obligation to acquire participations pursuant to this paragraph (c) 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 Revolving Credit Commitments, and that each
such payment shall be made without any offset, abatement, withholding or
reduction whatsoever.

     (d) Reimbursement. If the Facing Agent shall pay any drawing presented
under a Letter of Credit, Canco shall pay to the Facing Agent an amount equal to
the amount of such drawing not later than two hours after Canco shall have
received notice from the Facing Agent that payment of such drawing will be made
or, if Canco shall have received such notice later than 10:00 a.m., Standard
Time, on any Business Day, not later than 10:00 a.m., Standard Time on the
immediately following Business Day, provided that Canco may, subject to the
                                    --------
conditions to borrowing set forth herein, request in accordance with Section
                                                                     -------
2.03 that such payment be financed with an ABR Revolving Borrowing or, if such
----
LC Disbursement is denominated in Canadian Dollars, a Canadian Prime Rate
Borrowing (or failing such request, such LC Disbursement may be financed as an
ABR Revolving Borrowing or a Canadian Prime Rate Borrowing, as the case may be,
pursuant to Section 2.02(e)) in an equivalent amount and, to the extent so
            ----------------
financed, Canco's obligation to make such payment shall be discharged and
replaced by the resulting ABR Revolving Borrowing or Canadian Prime Rate
Borrowing, as the case may be. If Canco fails to make such payment when due, the
Facing Agent shall notify the Canadian Administrative Agent, which shall in turn
notify each Revolving Lender of the applicable LC Disbursement, the payment then
due from Canco in respect thereof and such Lender's Applicable Percentage
thereof. Promptly following receipt of such notice, each Revolving Lender shall
pay to the Canadian Administrative Agent its Applicable Percentage of the
payment then due from Canco, in the same manner as provided in Section 2.02(c)
                                                               ---------------
with respect to Loans made by such Lender, and the Canadian Administrative Agent
shall promptly pay to the Facing Agent the amounts so received by it from the
Revolving Lenders. Promptly following receipt by the Canadian Administrative
Agent of any payment from Canco pursuant to this paragraph (d), the Canadian
                                                 -------------
Administrative Agent shall distribute such payment to the Facing Agent or, to
the extent that Revolving Lenders have made payments pursuant to this paragraph
                                                                      ---------
(d) to reimburse the Facing Agent, then to such Lenders and the Facing Agent as
---
their interests may appear. Any payment made by a Revolving Lender pursuant to
this paragraph (d) to reimburse the Facing Agent for any LC Disbursement (other
     -------------
than the funding of ABR Revolving Loans or Canadian Prime Rate Loan as
contemplated above) shall not constitute a Loan and shall not relieve Canco of
its obligation to reimburse such LC Disbursement.
<PAGE>

     (e)  Obligations Absolute. Canco's obligation to repay the Facing Agent for
LC Disbursements made by the Facing Agent under the outstanding Letters of
Credit for the account of Canco shall be absolute, unconditional and irrevocable
under any and all circumstances and irrespective of:

          (i)   any lack of validity or enforceability of any Letter of Credit;

          (ii)  the existence of any claim, setoff, defense or other right that
     Canco or any other Person may at any time have against the beneficiary or
     any transferee under any Letter of Credit, the Facing Agent, the
     Administrative Agent, any Lender or any other Person (other than the
     defense of payment in accordance with the terms of this Agreement or a
     defense based on the gross negligence or wilful misconduct of the Facing
     Agent) in connection with this Agreement or any other agreement or
     transaction;

          (iii) any draft or other document presented under a Letter of Credit
     proving to be forged, fraudulent, invalid or insufficient in any respect or
     any statement therein being untrue or inaccurate in any respect, provided
     that payment by the Facing Agent under such Letter of Credit against
     presentation of such draft or document shall not have constituted gross
     negligence or wilful misconduct of the Facing Agent;

          (iv)  payment by the Facing Agent 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, provided that such payment shall not have
     constituted gross negligence or wilful misconduct of the Facing Agent; and

          (v)   any other circumstance or event whatsoever, whether or not
     similar to any of the foregoing, provided that such circumstance or event
     shall not have been the result of gross negligence or wilful misconduct of
     the Facing Agent.

     It is understood that in making any payment under a Letter of Credit (i)
the Facing Agent's exclusive reliance on the documents presented to it under
such Letter of Credit as to any and all matters set forth therein, including
reliance on the amount of any draft presented under such Letter of Credit,
whether or not the amount due to the beneficiary equals the amount of such draft
and whether or not any document presented pursuant to such Letter of Credit
proves to be insufficient in any respect, if such document on its face appears
to be in order, and whether or not any other statement or any other document
presented pursuant to such Letter of Credit proves to be forged or invalid or
any statement therein proves to be inaccurate or untrue in any respect
whatsoever, and (ii) any noncompliance in any immaterial respect of the
documents presented under a Letter of Credit with the terms thereof shall, in
each case, not be deemed wilful misconduct or gross negligence of the Facing
Agent.

     (f)  Disbursement Procedures. The Facing Agent shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Facing Agent shall promptly notify the
Canadian Administrative Agent and Canco by telephone
<PAGE>

                                                                              63

(confirmed by telecopy) of such demand for payment and whether the Facing Agent
has made or will make a LC Disbursement thereunder, provided that any failure to
give or delay in giving such notice shall not relieve Canco of its obligation to
reimburse the Facing Agent and the Revolving Lenders with respect to any such LC
Disbursement.

     (g) Interim Interest. If the Facing Agent shall make any LC Disbursement,
then, unless Canco 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 Canco reimburses such LC Disbursement, at the rate per annum then
applicable to ABR Revolving Loans or, if such LC Disbursement is denominated in
Canadian Dollars, Canadian Prime Rate Loans, provided that, if Canco fails to
                                             --------
reimburse such LC Disbursement when due pursuant to paragraph (d) of this
                                                    -------------
Article III, then Section 2.07 shall apply. Interest accrued pursuant to this
-----------       ------------
paragraph (g) shall be for the account of the Facing Agent, except that interest
-------------
accrued on and after the date of payment by any Revolving Lender pursuant to
paragraph (d) of this Article III to reimburse the Facing Agent shall be for the
-------------         -----------
account of such Lender to the extent of such payment.

     (h) Cash Collateralization. If any Event of Default shall occur and be
continuing, on the Business Day that Canco receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Revolving Lenders with LC Exposure representing greater
than 50% of the total LC Exposure) demanding the deposit of cash collateral
pursuant to this paragraph (h), Canco shall deposit in an account with the
                 -------------
Canadian Administrative Agent, in the name of the Canadian Administrative Agent
and for the benefit of the Lenders, an amount in cash equal to the LC Exposure
as of such date plus any accrued and unpaid fees and 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 Canco described in paragraph (g) or (h) of Article VIII. Each
                                   -------------    ---    ------------
such deposit shall be held by the Canadian Administrative Agent as collateral
for the payment and performance of the obligations of Canco under this
Agreement. The Canadian 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 Canadian Administrative
Agent and at Canco'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 Canadian Administrative
Agent to reimburse the Facing Agent 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 Canco for the LC Exposure at
such time or, if the maturity of the Loans has been accelerated (but subject to
the consent of Revolving Lenders with LC Exposure representing greater than 50%
of the total LC Exposure), be applied to satisfy other obligations of Canco
under this Agreement. If Canco is required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, such
amount (to the extent not applied as aforesaid) shall be returned to Canco
within three Business Days after all Events of Default have been cured or
waived.

     (i)  Replacement of the Facing Agent. The Facing Agent may be replaced at
any time by written agreement among Canco, each Agent, the Administrative Agent,
the replaced Facing Agent and the successor Facing Agent. Any such successor
Facing Agent shall be resident in Canada for purposes of the ITA. The
Administrative Agent shall notify the Lenders of any such replacement of the
Facing Agent. At the time any such replacement shall become effective, Canco
shall pay all unpaid fees accrued for the account of the replaced Facing Agent
pursuant to Section 2.05(c). From and after the effective date of any such
            ---------------
replacement, (i) the successor Facing Agent shall have all the rights and
obligations of the Facing Agent under this Agreement with respect to Letters of
Credit to be issued thereafter and (ii) references herein to the term "Facing
Agent" shall be deemed to refer to such successor or to any previous Facing
Agent, or to such successor and all previous Facing Agents, as the context shall
require. After the replacement of a Facing Agent hereunder, the replaced Facing
Agent shall remain a party hereto and shall continue to have all the rights and
obligations of a Facing Agent 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)  Additional Facing Agents. Canco may, at any time and from time to time
with the consent of the Agents (which consent shall not be unreasonably
withheld) and such Lender, designate one or more additional Revolving Lenders to
act as a Facing Agent under the terms of this Agreement. Any Revolving Lender
designated as a Facing Agent pursuant to this paragraph (j) of Article III shall
be deemed to be the "Facing Agent" (in addition to being a Lender) in respect of
Letters of Credit issued or to be issued by such Lender, and, with respect to
such Letters of Credit, such term shall thereafter apply to the Facing Agent and
such Lender.

     (k)  Notification by Facing Agents. On the first Business Day of each week,
each Facing Agent shall report to the Administrative Agent and the Canadian
Administrative Agent the aggregate face amount of Letters of Credit issued by it
and outstanding as of the last Business Day of the preceding week. The Canadian
Administrative Agent shall promptly notify the Revolving Lenders, in writing, of
the issuance of or any amendment to a Standby Letter of Credit, and if any
Revolving Lender so requests, the Canadian Administrative Agent shall provide
such Revolving Lender with copies of any such issuance or amendment.

                                  ARTICLE IV

                        Representations and Warranties

     Each of Stone and Canco represents and warrants to each of the Lenders, the
Agents, the Administrative Agent and the Facing Agent that:

     SECTION 4.01.  Organization; Powers. Each of the Loan Parties (a) is a

of the jurisdiction of its organization, (b) has all requisite power and

<PAGE>

                                                                              65

jurisdictions in which the failure so to qualify, in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect, and (d) has the
corporate power and authority to execute, deliver and perform its obligations
under each of the Loan Documents and each other agreement or instrument
contemplated thereby to which it is or will be a party and, in the case of the
Borrowers, to borrow hereunder.

proceeds of the Loans and the Letters of Credit, the creation of the security
interests contemplated by the Security Documents, the consummation of the
Acquisition and the other transactions contemplated by the Loan Documents and
the SLP Acquisition Documents (all the foregoing, collectively, the
"Transactions") (a) have been duly authorized by all requisite corporate and, if
 ------------
required, stockholder action and (b) will not (i) violate (A) any provision of
law, statute, rule or regulation, other than any law, statute, rule or
regulation the violation of which could not reasonably be expected to result in
a Material Adverse Effect, or of the certificate of incorporation or other
constitutive documents or by-laws of any Loan Party or any of their respective
Subsidiaries, (B) any order of any Governmental Authority, the violation of
which, solely with respect to the consummation of the Acquisition and the
transactions contemplated by the SLP Acquisition Documents, could not reasonably
be expected to result in a Material Adverse Effect, or (C) any provision of any
indenture or other material agreement or other material instrument to which any
Loan Party or any of their respective Subsidiaries is a party or by which any of
them or any of their property is or may be bound, the violation of which, solely
with respect to the consummation of the Acquisition and the transactions
contemplated by the SLP Acquisition Documents, could not reasonably be expected
to result in a Material Adverse Effect, (ii) constitute (alone or with notice or
lapse of time or both) a default under any such indenture, agreement or other
instrument where such default, solely with respect to the consummation of the
Acquisition and the transactions contemplated by the SLP Acquisition Documents,

result in the creation or imposition of any Lien (other than any Lien created
hereunder or under the Security Documents) upon or with respect to any property
or assets now owned or hereafter acquired by any Loan Party or any of their
respective Subsidiaries.

     SECTION 4.03.  Enforceability. This Agreement has been duly executed and
delivered by each Borrower and constitutes, and each other Loan Document when
executed and delivered by each Loan Party thereto will constitute, a legal,
valid and binding obligation of each Borrower and the Loan Parties, as
applicable, enforceable against each of them in accordance with its terms (a)
except as the enforceability thereof may be limited by bankruptcy, insolvency or
similar laws affecting creditors' rights generally and (b) subject to general
principles of equity.

     SECTION 4.04.  Governmental Approvals. No action, consent or approval of,
registration or filing with or any other action by any Governmental Authority is
or will be required in connection with the Transactions, except for (a) the
filing of Uniform Commercial Code financing statements, and similar security or
collateral filings and registrations under applicable laws in other

<PAGE>

                                                                              66

Office and the Ministry of Natural Resources under the Forest Act (Quebec) (in
respect of the Canco Hypothec only) and (d) such actions, consents, approvals,
registrations and filings as have been made or obtained and are in full force
and effect or the failure of which to make or obtain, solely with respect to the
consummation of the Acquisition and the transactions contemplated by the SLP
Acquisition Documents, could not reasonably be expected to result in a Material
Adverse Effect.

     SECTION 4.05.  Financial Statements. (a) Stone has delivered to the Lenders
(i) its audited financial statements and the audited financial statements of
Canco for the fiscal year ended December 31, 1999, together with its annual
report on Form 10-K and Canco's annual report on Form 20-F filed with the
Securities and Exchange Commission with respect to such fiscal year, and (ii)
its unaudited financial statements and the unaudited financial statements of
Canco for the fiscal quarter ended March 31, 2000, together with its quarterly
report on Form 10-Q filed with the Securities and Exchange Commission with
respect to such fiscal quarter. All financial statements set forth or referred
to in the materials specified in the preceding sentence were prepared in
conformity with U.S. GAAP or Canadian GAAP, as applicable, except with respect
to unaudited financial statements for the absence of footnote disclosure and for
year-end audit adjustments. All such financial statements fairly present in all
material respects the consolidated financial position of Stone and its
subsidiaries or Canco and its subsidiaries, as the case may be, as at the date
thereof and the consolidated results of operations and changes in financial
position of Stone and its subsidiaries or Canco and its subsidiaries, as the
case may be, for each of the periods covered thereby. Except as disclosed in
such financial statements, neither Stone nor Canco nor any of their respective
subsidiaries had, at the date of such financial statements or on the Closing
Date, as the case may be, any material contingent obligation, material
contingent liability or material liability for taxes, long-term lease or unusual
forward or long-term commitment or obligations to retired employees for medical
or other employee benefits that is not reflected in the foregoing financial
statements or the notes thereto.

     (b)  Stone has delivered to the Lenders its unaudited pro forma
consolidated balance sheet and statements of income as of December 31, 1999,
prepared giving effect to the Transactions as if they had occurred, with respect
to such balance sheet, on such date and, with respect to such other financial
statements, on the first day of the 12-month period ending on such date. Such
pro forma financial statements have been prepared in good faith by Stone, based
on the assumptions used to prepare the pro forma financial information contained
in the Confidential Information Memorandum (which assumptions are believed by
Stone on the Closing Date to be reasonable), present fairly on a pro forma basis
the estimated consolidated financial position of Stone and its consolidated
Subsidiaries as of such date and for such period, assuming that the Transactions
had actually occurred at such date or at the beginning of such period, as the
case may be.

     SECTION 4.06.  No Material Adverse Change. There has been no material
adverse change in the business, assets, operations, properties, prospects or
condition (financial or otherwise) of Stone and its consolidated Subsidiaries,
taken as a whole, since December 31, 1999.

     SECTION 4.07. Title to Properties; Possession Under Leases. (a) Except as
set forth on Schedule 4.07, each Borrower and the Subsidiaries have good and
             -------------
marketable title to, or valid leasehold interests in, all their respective
material properties and assets, except for minor defects in
<PAGE>

                                                                              67

title that do not interfere in any material respect with its ability to conduct
its business as currently conducted. All such title to, or leasehold interest
in, material properties and assets are free and clear of Liens, other than Liens
expressly permitted by Section 7.02 and Liens with respect to which BTCo, as
                       ------------
Collateral Agent, has received on or prior to the Closing Date duly executed
releases and termination statements in connection therewith.

     (b)  Each Borrower and the Subsidiaries have complied with all obligations
under all material leases to which it is a party and enjoys peaceful and
undisturbed possession under all such material leases necessary in any material
respect for the operation of their respective properties and assets.

     SECTION 4.08. Subsidiaries. Schedule 4.08 sets forth as of the Closing Date
                                 -------------
a list of all the Subsidiaries of each Borrower, their jurisdiction of
organization and the percentage ownership interest of each of them and any other
Subsidiary therein. The capital stock of each of the Subsidiaries is duly
authorized, validly issued, fully paid and nonassessable and, except as set
forth on Schedule 4.08, is owned free and clear of all Liens other than
         -------------
nonconsensual Permitted Liens arising other than as a result of a voluntary act
of the Borrowers. No authorized but unissued treasury shares of capital stock of
either Borrower or any such Subsidiary are subject to any option, warrant, right
to call or commitment of any kind or character except as set forth on Schedule
                                                                      --------
4.08.
----

     SECTION 4.09. Litigation; Compliance with Laws. (a) Except as set forth in
Schedule 4.09, there are not any actions, suits or proceedings at law or in
-------------
equity or by or before any Governmental Authority now pending or, to the
knowledge of either Borrower, threatened against or affecting either Borrower or
any of the Subsidiaries or any business or property of any such Person that (i)
involve any Loan Document or the Transactions or (ii) could reasonably be
expected to, individually or in the aggregate, result in a Material Adverse
Effect.

     (b)  Neither Borrower nor any of the Subsidiaries nor any of their
respective properties or assets is (i) in violation of, nor will the continued
operation of their properties and assets as currently conducted violate, any
law, rule, regulation, statute (including any zoning, building, environmental
and safety law; ordinance, code or approval or any building permits) or any
restrictions of record or agreements affecting the Mortgaged Properties, where
such violations could reasonably be expected to have a Material Adverse Effect
or (ii) in default with respect to any judgment, writ, injunction, decree or
order of any Governmental Authority, where such defaults, individually or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect.

     SECTION 4.10.  Agreements. Neither Borrower nor any of the Subsidiaries is
in default under any provision of any indenture or other agreement or instrument
evidencing Indebtedness, or any other agreement or instrument to which it is a
party or by which it or any of its properties or assets are or may be bound,
where such default could reasonably be expected to result in a Material Adverse
Effect.

     SECTION 4.11.  Federal Reserve Regulations. (a) Neither Borrower nor any of
the Subsidiaries is engaged principally, or as one of its important activities,
in the business of extending credit for the purpose of purchasing or carrying
Margin Stock.
<PAGE>

                                                                              68

     (b) No part of the proceeds of any Letter of Credit or Loan has been used,
whether directly or indirectly, and whether immediately, incidentally or
ultimately, (i) to purchase or carry Margin Stock or to extend credit to others
for the purpose of purchasing or carrying Margin Stock or to refund indebtedness
originally incurred for such purpose or (ii) for any purpose that entails a
violation of, or is inconsistent with, the provisions of the Regulations of the
Board, including Regulation T, U or X.

     SECTION 4.12.  Investment Company Act; Public Utility Holding Company Act.
Neither Borrower nor any of the Subsidiaries (a) is an "investment company" as
defined in, or is subject to regulation under, the Investment Company Act of
1940 or (b) is a "holding company" as defined in, or is subject to regulation
under, the Public Utility Holding Company Act of 1935.

     SECTION 4.13.  Tax Returns. Each of the Borrowers and the Subsidiaries has
filed or caused to be filed all Federal, foreign, state and local income and
other material tax returns required to have been filed by it or with respect to
it and has paid or caused to be paid all taxes shown to be due and payable on
such returns or on any assessments received by it or with respect to it, except
taxes that are being contested in good faith by appropriate proceedings and for
which it has set aside on its books adequate reserves in accordance with U.S. or
Canadian GAAP, as applicable.

     SECTION 4.14. No Material Misstatements. The information provided by or on
behalf of the Borrowers and contained in the Confidential Information Memorandum
(including all attachments and exhibits thereto), as supplemented, and as
supplemented further by information heretofore provided in writing by or on
behalf of the Borrowers to the Lenders and any other materials, documents and
information that the Borrowers or any of their Affiliates may have furnished to
the Lenders, was as of the date of such Confidential Information Memorandum, the
dates otherwise specified therein or the dates upon which such information was
provided, when taken as a whole, accurate in all material respects and does not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, when taken as a whole, not materially misleading,
provided that to the extent any such information therein was based upon or
constitutes a forecast or projection, each Borrower represents only that it
acted in good faith and utilized reasonable assumptions, due and careful
consideration and the information actually known to Responsible Officers of each
Borrower at the time in the preparation of such information.

     SECTION  4.15.  Employee Benefit Plans. (a) Each Borrower and their
respective ERISA Affiliates is in compliance in all material respects with the
applicable provisions of ERISA and the Code and the regulations and published
interpretations thereunder. No Reportable Event has occurred in respect of any
Plan of either Borrower or any ERISA Affiliate. The present value of all
actuarial accrued liabilities under each Plan (based on those assumptions used
to fund such Plan) did not, as of the last annual valuation date applicable
thereto, exceed by more than U.S.$25,000,000 the value of the assets of such
Plan, and the present value of all actuarial accrued liabilities of all
underfunded Plans (based on those assumptions used to fund each such Plan) did
not, as of the last annual valuation dates applicable thereto, exceed by more
than U.S.$25,000,000 the value of the

assets of all such underfunded Plans. Neither Borrower nor any ERISA Affiliate
has incurred any Withdrawal Liability that could result in a Material Adverse
Effect. Neither Borrower nor any ERISA Affiliate has received any notification
that any Multiemployer Plan is in reorganization or has been terminated within
the meaning of Title IV of ERISA and no Multiemployer Plan is reasonably
expected to be in reorganization or to be terminated where such reorganization
or termination has resulted or could reasonably be expected to result, through
increases in the contributions required to be made to such Plan or otherwise, in
a Material Adverse Effect.

     (b) The Canadian Pension Plans are duly registered under the ITA and any
other applicable laws which require registration, have been administered in all
material respects in accordance with the ITA and such other applicable laws and
no event has occurred which could reasonably be expected to cause the loss of
such registered status. All material obligations of Canco and each of its
Subsidiaries required to be performed by Canco or its Subsidiaries in connection
with the Canadian Pension Plans and the funding agreements therefor have been
performed on a timely basis. As of the Closing Date, there are no outstanding
disputes concerning the assets of the Canadian Pension Plans or the Canadian
Benefit Plans. No promises of benefit improvements under the Canadian Pension
Plans or the Canadian Benefit Plans have been made except where such improvement
could not reasonably be expected to have a Material Adverse Effect. All
contributions or premiums required to be made or paid by Canco and each of its
Subsidiaries to the Canadian Pension Plans or the Canadian Benefit Plans have
been made on a timely basis in accordance with the terms of such plans and all
applicable laws. There have been no improper withdrawals or applications of the
assets of the Canadian Pension Plans or the Canadian Benefit Plans. None of the
Canadian Pension Plans or the Canadian Benefit Plans has any unfunded actuarial
liabilities or solvency deficiencies (within the meaning of the Quebec
Supplemental Pension Plans Act) in an aggregate amount in excess of
U.S.$25,000,000.

          (b)  Each Borrower and each of the Subsidiaries is in compliance with
     all material terms and conditions of the permits, licenses and

     that it has been identified as a potentially responsible party under CERCLA
     or any comparable state law, nor has either Borrower or any of the

     constituents, hazardous materials, asbestos or asbestos containing
     material, polychlorinated biphenyls, petroleum, including crude oil and any
     fractions thereof, or other wastes, chemicals, substances or materials
     regulated by any Environmental Laws (collectively, "Hazardous Materials")
                                                         -------------------
     that it or any of their respective predecessors in interest has used,
     generated, stored, tested, handled, transported or disposed of, has been
     found at any site at which any Governmental Authority or private party is
     conducting a remedial investigation or other action pursuant to any
     Environmental Law, except in each case for any such notices that,
     individually or in the aggregate, could not reasonably be expected to
     result in a Material Adverse Effect.

          (e) There have been no releases or threatened releases (in each case
     as defined in CERCLA) of Hazardous Materials by either Borrower or any of
     the Subsidiaries on, upon, into or from any of the Real Properties, which

     Material Adverse Effect. To the best knowledge of each Borrower and each of
     the Subsidiaries, there have been no such releases or threatened releases
     on, upon, under or into any real property in the vicinity of any of the
     Real Properties that, through soil, surface water or groundwater migration
     or contamination, may be located on, in or under such Real Properties and
     which could reasonably be expected to result in a Material Adverse Effect.

          (f) To the best knowledge of each Borrower and each of the
     Subsidiaries, there is no asbestos in, on, or at any Real Properties or any
     facility or equipment of either Borrower or any of the Subsidiaries except
     to the extent that the presence of such material could not reasonably be
     expected to result in a Material Adverse Effect.

          (g) None of the Mortgaged Properties and, to the best knowledge of
     each Borrower and each of the Subsidiaries after due inquiry, none of the
     other Real Properties of either Borrower or any of the Subsidiaries are (i)
     listed or proposed for listing on the National Priorities List under CERCLA
     or (ii) listed in the Comprehensive Environmental Response, Compensation,
     Liability Information System List promulgated pursuant to CERCLA, or on any
     comparable list maintained by any Governmental Authority.

          (h) There are no past or current events, conditions, circumstances,
     activities, practices, incidents, actions or plans that could reasonably be
     anticipated to interfere with or prevent compliance with any Environmental
     Law, or which may give rise to liability under any Environmental Law, or
     otherwise form the basis of any claim, action, demand, suit, proceeding,
     hearing or notice of violation, study or investigation, based on or related
     to the manufacture, processing, distribution, use, generation, treatment,
     storage, disposal, transport, shipping or handling, or the emission,
     discharge, release or threatened release into the environment, of any
     Hazardous Material that could reasonably be expected to result in a
     Material Adverse Effect.

     SECTION 4.17.  Solvency. After giving effect to the Transactions to occur
on the Closing Date, (a) the fair salable value of the assets of Stone and the
Subsidiaries, on a consolidated basis, will exceed the amount that will be
required to be paid on or in respect of the existing debts and other liabilities
(including contingent liabilities) of Stone and the Subsidiaries, on a
consolidated basis, as they mature, (b) the assets of Stone and the
Subsidiaries, on a consolidated basis, will not constitute unreasonably small
capital to carry out their businesses as conducted or as proposed to be
conducted, including the capital needs of Stone and its Subsidiaries, on a
consolidated basis (taking into account the particular capital requirements of
the businesses conducted by such entities and the projected capital requirements
and capital availability of such businesses) and (c) neither Borrower intends
to, nor does it intend to permit any of the Subsidiaries to, and does not
believe that it or any such Subsidiary will, incur debts beyond its ability to
pay such debts as they mature (taking into account the timing and amounts of
cash to be received by each of them or any such Subsidiary and the amounts to be
payable on or in respect of its obligations).

to any other Person other than with respect to Permitted Liens. 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 registered Intellectual Property
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 Permitted
Liens (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).

     (ii) The Canadian Security Agreement creates in favor of BTCo, as
Collateral Agent, for the ratable benefit of the beneficiaries named therein, a
legal, valid and enforceable security interest in the Collateral (as defined in
the Canadian Security Agreement) and proceeds thereof, and when financing

and interest of the Loan Parties in the registered Intellectual Property (as
defined in the Canadian 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 Canadian Intellectual Property Office,

-------------
Borrowers have not been in violation of the Fair Labor Standards Act or any
other applicable Federal, state, local or foreign law dealing with such matters,
where such violations could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect. The consummation of the
Transactions will not give rise to a right of termination or right of
renegotiation on the part of any union under any collective bargaining agreement
to which either Borrower or any of the Subsidiaries is a party or by which
either Borrower or any of the Subsidiaries is bound on the Closing Date.

     SECTION 4.20.  Location of Real Property. (a) Schedule 4.20 sets forth

completely and correctly as of the Closing Date all material real property owned

with respect to Canco and its Subsidiaries, Canada, and the addresses thereof.
All the real property set forth on Schedule 4.20 is owned in fee by a Borrower

respect to the foregoing that are (a) used in or necessary for the conduct of
their respective businesses as currently conducted and (b) material to the
business, assets, operations, properties, prospects or condition (financial or
otherwise) of the Borrowers and the Subsidiaries taken as a whole. The use of
such patents, trademarks, trade names, copyrights, technology, know-how,
processes and rights with respect to the foregoing by the Borrowers and the
Subsidiaries does not infringe on the rights of any Person, subject to such
claims and infringements as do not, in the aggregate, give rise to any liability
on the part of either Borrower and the Subsidiaries that is material to the
Borrowers and the Subsidiaries, taken as a whole. To the best knowledge of each
Borrower, its rights and the rights of the Subsidiaries to sell, franchise or
license

contained in this Agreement and the other Loan Documents shall survive the
effectiveness of this Agreement and such other Loan Documents as the case may

documents, financing statements, agreements and instruments, and take all
further action (including filing Uniform Commercial Code and other financing
statements, mortgages, hypothecs and deeds of trust), that may be required under

contemplated by the Loan Documents and in order to grant, preserve, protect and
perfect the validity and first priority of the security interests created or
intended to be created by the Security Documents.

     (b)  Cause (i) each Subsidiary that is or becomes a Material Subsidiary and
(ii) each Domestic Subsidiary of SLP US or Canadian Subsidiary of Canco (in each
case, other than any Inactive Subsidiary) to undertake the obligation of, and to

Stone Subsidiary Guarantee Agreement, as applicable; provided, however, that no

perfected (or, in the case of assets or properties located in the Province of
Quebec, published) security interests with respect to such of the assets and
properties of SLP US and its wholly owned Domestic Subsidiaries and of Canco and
its wholly owned Canadian Subsidiaries as either Agent or the Required Lenders
shall reasonably request (it being understood that it is the intent of the
parties that to the extent not prohibited by any Specified Senior Indenture, (x)
the Obligations of Stone shall be secured by substantially all of the assets of
SLP US and its wholly owned Domestic Subsidiaries and (y) the Obligations of
Canco shall be secured by substantially all of the assets of SLP US and its
wholly owned Domestic Subsidiaries and by substantially all of the assets of
Canco and all wholly owned Canadian Subsidiaries of Canco (other than assets
owned directly or indirectly by Stone prior to the Acquisition)). Such security
interests and Liens will be created under the Security Documents and other
security agreements, mortgages,

deeds of trust and other instruments and documents in form and substance
reasonably satisfactory to the Collateral Agent, and the Borrowers shall deliver
or cause to be delivered to the Lenders all such instruments and documents
(including customary legal opinions, title insurance policies or title opinions
and lien searches) as the Collateral Agent shall reasonably request to evidence
compliance with this Section. The Borrowers agree to provide such evidence as
the Collateral Agent shall reasonably request as to the perfection and priority
status of each such security interest and Lien. Notwithstanding the foregoing,
no after-acquired real property having a value of less than U.S.$500,000 shall
be required to be mortgaged or pledged to secure all or any part of the
Obligations. To the extent that the assets and/or properties of any Subsidiary
of SLP US or Canco existing on the date hereof are not pledged because (x) of a
legal or other restriction impeding such pledge or (y) such Subsidiary is not
wholly owned, if such restriction subsequently becomes inapplicable or such
Subsidiary subsequently becomes wholly owned, the Borrowers will, at their cost
and expense, promptly cause the assets and/or properties of such Subsidiary to
be pledged and the security interest therein perfected or published, as
applicable.

     (d)  In the event that any survey of Mortgaged Property discloses any
matter (including any encroachment or violation of an existing servitude, right
of way, reservation made in the grant from the Crown easement or restrictive
covenant) the effect of which is to detract materially from the value of the
property subject thereto or to interfere in any material respect with the
ordinary conduct of the business of either Borrower or any of the Subsidiaries,
the applicable Borrower shall, reasonable upon request by any Agent or the
Administrative Agent, use reasonable efforts (or cause the Subsidiary that is
the user or owner of the Mortgaged Property in question to use reasonable
efforts) to cause such matter to be corrected or otherwise resolved to the
reasonable satisfaction of the Agents.

     (e)  Cause the Canadian Amalgamations and the Post Closing Distributions to
occur as promptly as practicable (and in any event within 10 days) following the
Closing Date, and provide reasonably satisfactory evidence thereof to the
Agents.

     SECTION 6.11.  Material Contracts. Maintain in full force and effect
(including exercising any available renewal option), and without amendment or
modification, each Material Contract, unless the failure so to maintain any such
Material Contract (or any amendment or modification thereto) could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     SECTION 6.12.  Environmental Matters. (a) Promptly give notice to the
Administrative Agent upon becoming aware of (i) any violation of any
Environmental Law, (ii) any claim, inquiry, proceeding, investigation or other
action, including a request for information or a notice of potential
environmental liability, by or from any Governmental Authority or any third
party claimant or (iii) the discovery of the release of any Hazardous Material
at, on, under or from any of the Real Properties or any facility or equipment
thereat in excess of reportable or allowable standards or levels under any
Environmental Law, or in a manner or amount that could reasonably be expected to
result in liability under any Environmental Law, in each case that could
reasonably be expected to result in a Material Adverse Effect.

     (b)  Upon discovery of the presence on any of the Real Properties of any
Hazardous Material that is in violation of, or that could reasonably be expected
to result in liability under, any Environmental Law, in each case that could
result in a Material Adverse Effect, take all necessary steps to initiate and
expeditiously complete all remedial, corrective and other action to eliminate
any such adverse effect, and keep the Administrative Agent informed of such
actions and the results thereof.

          SECTION 6.13 Surveys.  Within 120 days after the Closing Date, for
each Mortgaged Property identified on Schedule 6.13 attached hereto having a
                                      -------------
fair market value of U.S.$1,000,000 or more, deliver or cause to be delivered
(i) an A.L.T.A. survey or (ii) a perimeter survey as indicated on such Schedule,

Administrative Agent and endorsements to the title policies required by Section
                                                                        -------

Lenders shall otherwise consent in writing, it will not, and will not cause or

          The Agents, the Administrative Agents and the Facing Agent

     In order to expedite the transactions contemplated by this Agreement, (a)
each of The Chase Manhattan Bank and Bankers Trust Company is hereby appointed

Company is hereby appointed to act as Administrative Agent and Collateral Agent
for the Facing Agent and the Lenders and (c) Deutsche Bank Canada  is hereby

and the Canadian Administrative Agent for purposes of this Article IX are
                                                           ----------
collectively referred to as the "Agents").  Each of the Lenders and the Facing
                                 ------
Agent hereby irrevocably authorizes each Agent to take such actions on its
behalf and to exercise such powers as are specifically delegated to such Agent
by the terms and provisions hereof and of the other Loan Documents, together
with such actions and powers as are reasonably incidental thereto.  Each of the
Agents is expressly authorized by the Lenders and the Facing Agent, without
limiting any implied authority, to receive all Loan Documents on the Closing
Date.  The Administrative Agent is expressly authorized by the Lenders and the
Facing Agent, without limiting any implied authority, (a) to receive on behalf
of the Lenders and the Facing Agent all payments of principal of and interest on
the Loans, all payments in respect of LC Disbursements and all other amounts due
to the Lenders and the Facing Agent hereunder, and promptly to distribute to
each Lender and the Facing Agent its proper share of each payment so received,
(b) to give notice on behalf of each of the Lenders to the Borrowers of any
Event of Default specified in this Agreement of which the Administrative Agent
has actual knowledge acquired in connection with its agency hereunder and (c) to
distribute to each Lender and the Facing Agent copies of all notices, financial
statements and other materials delivered by the Loan Parties pursuant to this
Agreement as received by the Administrative Agent (including notices of an
occurrence of any Event of Default). BTCo, as Collateral Agent, is expressly
authorized to execute any and all documents (including releases) with respect to
the Collateral and the Program Receivables and the rights of the Lenders with
respect thereto and to act as Collateral Agent on behalf of the Lenders, in each
case as contemplated by and in accordance with the terms and provisions of this
Agreement and the Security Documents, including the right to be the sole
bondholder of the Bonds and to hold them as pledgee for the benefit of the
Tranche H Lenders, the Revolving Lenders, the Agents, and the Facing Agent.

     For greater certainty and without limiting the powers of the Collateral
Agent herein and for purposes of constituting security on any of the Collateral,
present or future, of any of Canco or any of its Subsidiaries located or deemed
located in the Province of Quebec, as security for the due payment of the Bonds,
Canco and its Subsidiaries, the Tranche H Lenders, the Revolving Lenders, the
Agents and the Facing Agent hereby acknowledge and agree that the Trustee is,
for the purposes of holding any security granted by any of Canco or any of its
Subsidiaries pursuant to the laws of the Province of Quebec, the holder of an
irrevocable power of attorney for all present and future Bondholders.  By the
execution of any Assignment and Acceptance, any future Tranche H Lender or
Revolving Lender shall be deemed to ratify the power of attorney granted to the
Trustee hereunder.  Furthermore, the Collateral Agent hereby agrees to act in
the capacity of the collateral

agent and depositary of the Bonds for the benefit of all present and future
Tranche H Lenders, Revolving Lenders, Agents and Facing Agent. Any future
Tranche H Lenders or Revolving Lenders shall be deemed to reconfirm the above
mandate of the Collateral Agent. Canco and its Subsidiaries, the Agent, the
Facing Agent, the Tranche H Lenders and the Revolving Lenders agree that (a)
notwithstanding the provisions of Section 32 of the Act Respecting Special
Powers of Legal Persons (Quebec), the Trustee may acquire any title or
indebtedness secured by the Hypothecs, and that (b) the Bonds constitute "titles
of indebtedness" within the meaning of such term in Article 2692 of the Civil
Code of Quebec.

     None of the Agents or the Facing Agent or any of their respective
directors, officers, employees or agents shall be liable as such for any action
taken or omitted by any of them except for its, his or her own gross negligence
or wilful misconduct, or be responsible for any statement, warranty or
representation herein or the contents of any document delivered in connection
herewith, or be required to ascertain or to make any inquiry concerning the
performance or observance by the Loan Parties of any of the terms, conditions,
covenants or agreements contained in any Loan Document.  None of the Agents
shall  be responsible to the Lenders or the Facing Agent for the due execution,
genuineness, validity, enforceability or effectiveness of this Agreement, any
other Loan Document or any other instruments or agreements.  Each Agent shall in
all cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders (and the Facing Agent,
with respect to Letters of Credit) and, except as otherwise specifically
provided herein, such instructions and any action or inaction pursuant thereto
shall be binding on all the Lenders and the Facing Agent.  Each Agent shall, in
the absence of knowledge to the contrary, be entitled to rely on any instrument
or document believed by them in good faith to be genuine and correct and to have
been signed or sent by the proper Person or Persons.  None of the Agents or the
Facing Agent or any of their respective directors, officers, employees or agents
shall have any responsibility to the Loan Parties on account of the failure of
or delay in performance or breach by any Lender (or, in the case of the Agents,
by the Facing Agent) of any of its obligations hereunder or to any Lender (or,
in the case of the Agents, the Facing Agent) on account of the failure of or
delay in performance or breach by any other Lender (or, in the case of the
Agents, the Facing Agent) or the Loan Parties or any Guarantor of any of their
respective obligations hereunder or under any other Loan Document or in
connection herewith or therewith.  Each Agent and the Facing Agent may execute
any and all duties hereunder by or through agents or employees and shall be
entitled to rely upon the advice of legal counsel selected by any of them with
respect to all matters arising hereunder and shall not be liable for any action
taken or suffered in good faith by any of them in accordance with the advice of
such counsel.

     The Lenders and the Facing Agent hereby acknowledge that none of the Agents
or the Facing Agent shall be under any duty to take any discretionary action
permitted to be taken by it pursuant to the provisions of this Agreement unless
it shall be requested in writing to do so by the Required Lenders.

     Subject to the appointment and acceptance of a successor Agent as provided
below, any Agent may resign at any time by notifying the other Agents, the
Lenders, the Facing Agent and the Borrowers.  Upon any such resignation, the
Required Lenders (or, in the case of the resignation of

the Canadian Administrative Agent, a majority in interest of the Revolving
Lenders) shall have the right to appoint a Lender as the successor. If no
successor shall have been so appointed by the Required Lenders or the Revolving
Lenders, as the case may be, 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 Facing Agent, appoint a successor
Agent, which shall be a bank with an office in New York, New York (or, in the
case of the Canadian Administrative Agent, Toronto, Ontario), having a combined
capital and surplus of at least U.S.$500,000,000 or an Affiliate of any such
bank. Upon the acceptance of any appointment as Agent hereunder by a successor
bank, 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. After any Agent's
resignation hereunder, the provisions of this Article IX and Section 11.05 shall
                                              ----------     -------------
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

     With respect to the Loans made by it hereunder, each Agent and the Facing
Agent, in its individual capacity and not as Agent or Facing Agent, as the case
may be, shall have the same rights and powers as any other Lender and may
exercise the same as though it were not an Agent or the Facing Agent, as the
case may be, and each Agent and its Affiliates and the Facing Agent and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Loan Parties or any of their respective Subsidiaries
or other Affiliates as if it were not an Agent or the Facing Agent, as the case
may be.

     Each Lender agrees (a) to reimburse each Agent and the Facing Agent, on
demand, in the amount of such Lender's pro rata share (based on its Commitments
hereunder (provided that (x) in the case of the Tranche G Loans or Tranche H
           --------
Loans or (y) in the event that such Commitments shall have expired or been
terminated, such pro rata share shall be based on the respective principal
amounts of the outstanding Loans)) of any expenses incurred for the benefit of
the Lenders by such Agent or the Facing Agent, including fees, disbursements and
other charges of counsel and compensation of agents paid for services rendered
on behalf of the Lenders, that shall not have been reimbursed by the Loan
Parties and (b) to indemnify and hold harmless each Agent and the Facing Agent
and any of their respective directors, officers, employees or agents, on demand,
in the amount of such pro rata share, from and against any and all liabilities,
taxes, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by or asserted against it in its capacity as an Agent or
the Facing Agent, as the case may be, or any of them in any way relating to or
arising out of this Agreement or any other Loan Document or any action taken or
omitted by it or any of them under this Agreement or any other Loan Document, to
the extent the same shall not have been reimbursed by the Loan Parties;
provided, however, that (i) no Lender shall be liable to any Agent or the Facing

Agent for any portion of such liabilities, obligations, losses, damages,

from the gross negligence or wilful misconduct of such Agent or the Facing
Agent, as the case may be, or any of their respective directors, officers,
employees or agents and (ii) each Lender that does not have a Revolving Credit
Commitment (other than through the expiration or termination thereof) shall be
under no obligation to reimburse or indemnify the Facing Agent under clauses (a)
                                                                     -----------

     Each Lender acknowledges that it has, independently and without reliance
upon any Agent, any other Lender or the Facing Agent 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, any other Lender or the
Facing Agent 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 or any other Loan Document, any
related agreement or any document furnished hereunder or thereunder.

                                   ARTICLE X

                        Collection Allocation Mechanism

     SECTION 10.01.  Implementation of CAM. (a) On the CAM Exchange Date, the
Lenders shall automatically and without further act (and without regard to the
provisions of Section 11.04) 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 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 Borrower 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 Borrower agrees from time to time to execute and deliver
to the Agents all instruments and documents as either Agent shall reasonably
request to evidence and confirm the respective interests of the Lenders after
giving effect to the CAM Exchange.

     (b)  As a result of the CAM Exchange, upon and after the CAM Exchange Date,
each payment received by the Administrative Agent or the Collateral Agent
pursuant to any Loan Document in respect of the Designated Obligations, and each
distribution made by the Collateral Agent pursuant to any Security Document 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
Administrative Agent 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 Canco or with the proceeds of a Revolving Credit Borrowing,
each Revolving Lender shall promptly pay over to the Administrative Agent, in
immediately available funds in the same currency as such Letter of Credit, in
the case of any undrawn amount, and in U.S. Dollars, in the case of any
unreimbursed amount, an amount equal to such
<PAGE>

                                                                             105

Revolving Lender's Applicable Percentage of such undrawn face amount or (to the
extent it has not already done so) such unreimbursed drawing, as the case may
be, together with interest thereon from the CAM Exchange Date to the date on
which such amount shall be paid to the Administrative Agent at the rate that
would be applicable at the time to an ABR Revolving Loan or Canadian Prime Rate
Loan, as the case may be, in a principal amount equal to such amount. The
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
Administrative Agent shall deposit in each Lender's LC Reserve Account such
Lender's CAM Percentage of the amounts received from the Revolving Lenders as
provided above. The 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 L/C Reserve Account until withdrawn as provided in
paragraph (b), (c), (d) or (e) below.  The 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 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 outstanding L/C 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 either
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 Article III.
                                             -----------

     (b)  In the event that after the CAM Exchange Date any drawing shall be
made in respect of a Letter of Credit, the Administrative Agent shall, at the
request of the Facing Agent, 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 Facing Agent in satisfaction of the reimbursement
obligations of the Revolving Lenders under subsection (c) of Article III (but
                                                      ---    -----------
not of Canco under subsection (d) of Article III).  In the event any Revolving
                              ---    ------------
Lender shall default on its obligation to pay over any amount to the
Administrative Agent in respect of any Letter of Credit as provided in this
Section 10.02, the Facing Agent shall, in the event of a drawing thereunder,
-------------
have a claim against such Revolving Lender to the same extent as if such Lender
had defaulted on its obligations under subsection (c) of Article III, but shall
                                                  ---    -----------
have no claim against any other Lender in respect of such defaulted amount,
notwithstanding the exchange of interests in Canco's reimbursement obligations
pursuant Section 10.01.  Each other Lender shall have a claim against such
         -------------
defaulting 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 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 Administrative Agent and the
Facing Agent (not to be unreasonably withheld), any Lender may withdraw the
amount held in its LC Reserve Account
<PAGE>

                                                                             106

in respect of the undrawn amount of any Letter of Credit. Any Lender making such
a withdrawal shall be unconditionally obligated, in the event there shall
subsequently be a drawing under such Letter of Credit, to pay over to the
Administrative Agent, for the account of the Facing Agent, 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 Administrative
Agent will, at the direction of such Lender and subject to such rules as the
Administrative Agent may prescribe for the avoidance of inconvenience, invest
such amounts in Permitted Investments. Each Lender which 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
Administrative Agent, to withdraw the earnings on investments so made by the
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 any currency other than U.S.
Dollars (other than, for the avoidance of doubt, obligations in respect of
undrawn Letters of Credit denominated in Canadian Dollars) shall, automatically
and with no further act required, be converted to obligations of the same Loan
Parties denominated in U.S. Dollars. Such conversion shall be effected based
upon the Exchange Rates in effect with respect to the relevant currencies 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
U.S. 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 Borrowers and the 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 their
original currencies.

not be considered an assignment of such Borrower's duties hereunder and would
instead be subject to the restrictions of Section 7.05).

notice being expressly waived by each Borrower), to exercise its banker's lien
or right of setoff 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 such Lender to or for the credit or the account of any Loan Party
against any of and all the obligations of the Borrowers now or hereafter

as Collateral Agent, to release, or to cause the Trustee to release, any Lien
held by it under the Security Documents under the following circumstances:

          (a)  upon final and indefeasible payment in full in cash of the Loans
     and Obligations (other than unasserted contingent and indemnification
     obligations which expressly survive termination) and termination of all
     Commitments and termination hereof, BTCo, as Collateral Agent, is

     created under the Loan Documents;

          (c)  upon consent by the Required Lenders, BTCo, as Collateral Agent,
     is authorized to release, or to cause the Trustee to release, such Liens on
     any part of the Collateral which release does not require the consent of
     all of the Lenders as set forth in Section 11.08;
                                        -------------

provided, however, that (i) the Collateral Agent shall not be required to
--------  -------
execute any such document on terms which, in its opinion, would expose it to
liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty, and (ii) such release shall
not in any manner discharge, affect or impair the Obligations or any Liens upon
(or obligations of either Borrower or any of the Subsidiaries in respect of) all
interests retained by the Borrowers or any of the Subsidiaries.

     SECTION 11.10.  Interest Rate Limitation.  Notwithstanding anything herein
to the contrary, if at any time the applicable interest rate, together with all
fees and charges that are treated as interest under applicable law
(collectively, the "Charges"), as provided for herein or in any other document
                    -------
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by any Lender, shall exceed the maximum lawful rate (the

"Maximum Rate") that may be contracted for, charged, taken, received or reserved
-------------
by such Lender in accordance with applicable law, the rate of interest payable
to such Lender hereunder, together with all Charges payable to such Lender,
shall be limited to the Maximum Rate.

     SECTION 11.11.  Entire Agreement.  This Agreement, the other Loan
Documents and any separate letter agreements with respect to fees payable to any
Agent, the Administrative Agent or the Facing Agent constitute the entire
contract between the parties relative to the subject matter hereof.  Any
previous agreement among the parties with respect to the subject matter hereof
is superseded by this Agreement and the other Loan Documents.  Nothing in this
Agreement or in the other Loan Documents, expressed or implied, is intended to
confer upon any party other than the parties hereto and thereto any rights,
remedies, obligations or liabilities under or by reason of this Agreement or the
other Loan Documents.

     SECTION 11.12.  Waiver of Jury Trial.  Each party hereto hereby waives, to
the fullest extent permitted by applicable law, any right it may have to a trial
by jury in respect of any litigation directly or indirectly arising out of,
under or in connection with this Agreement or any of the other Loan Documents.
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 and the other Loan Documents, as applicable, by, among other
things, the mutual waivers and certifications in this Section 11.12.
                                                      -------------

     SECTION 11.13.  Severability.  In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby.  The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions, the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

     SECTION 11.14.  Headings.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

     SECTION 11.15.  Confidentiality.  (a)  Each Lender agrees not to disclose
to any Person the Information (as defined below) in accordance with such
Lender's customary procedures for non-disclosure of confidential information of
third parties of this nature and in accordance with safe and sound lending
practices without the prior written consent of the Borrowers, which consent
shall not be unreasonably withheld, except that any Lender shall be permitted to
disclose Information (i) to its and its Affiliates' officers, directors,
employees, agents and representatives (including its auditors and counsel) or to
any direct or indirect contractual counterparty in swap agreements or such
contractual counterparty's professional advisor (so long as such contractual
counterparty or professional advisor to such contractual counterparty agrees in
writing to be bound by the provisions of this Section 11.15); (ii) to the extent
                                              -------------
(A) required by applicable laws and regulations or by any subpoena or similar
legal process or (B) requested or required by any regulatory authority or The
National Association of Insurance Commissioners or any similar organization, or
any nationally recognized rating agency that requires access to information
about a Lender's investment portfolio; (iii) to the extent such Information (A)
becomes publicly available other than as a result of a breach of this Agreement,
(B) becomes available to such Lender on a non-confidential basis from a source
other than a Loan Party or its Affiliates or (C) was available to such Lender on
a non-confidential basis prior to its disclosure to such Lender by a Loan Party
or its Affiliates; (iv) to any actual or prospective assignee of, or prospective
purchaser of a participation in, the rights of such Lender hereunder, in each
case subject to paragraph (c) below; or (v) in connection with any suit, action
                -------------
or proceeding relating to the enforcement of rights hereunder or under any other
Loan Document or in connection with the transactions contemplated hereby.  As
used in this Section 11.15, as to any Lender, the term "Information" shall mean

materials, documents and information that either Borrower or any of its
Affiliates may have furnished or may hereafter furnish to any Lender in
connection with this Agreement.

     (b)  Each Lender agrees that it will use the Information only for purposes
related to the transactions contemplated hereby and by the other Loan Documents,
provided that (i) if the conditions referred to in any of subclauses (A) through
--------                                                  --------------
(C) of clause (iii) of paragraph (a) above are met, such Lender may otherwise
---    ------------    -------------
use the Information and (ii) if such Lender or any of its Affiliates is
otherwise a creditor of a Loan Party, such Lender or any such Affiliate may use
the Information in connection with its other credits to such Loan Party.

     (c)  Each Lender agrees that it will not disclose any of the Information to
any actual or prospective assignee of such Lender or participant in any rights
of such Lender under this Agreement unless such actual or prospective assignee
or participant first executes and delivers to such Lender or the Borrowers a
confidentiality letter containing substantially the undertakings set forth in
this Section 11.15.
     -------------

     SECTION 11.16.  Jurisdiction; Consent to Service of Process.  (a) Each
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such 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 shall affect any right that any
Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against any Loan Party or its properties
in the courts of any jurisdiction.

     (b)  Each Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that 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 the other Loan Documents in any
New York State or Federal court.  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.

     (c)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 11.01.  Nothing in this
                                              -------------
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

     SECTION 11.17.  Judgment Currency.  (a)  Except as otherwise provided in
Section 10.03, the Borrowers' obligations hereunder and the Borrowers' and the
--------------
other Loan Parties' obligations under the other Loan Documents to make payments
in U.S. Dollars or in Canadian Dollars (the
<PAGE>

                                                                             117

"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 applicable Administrative
Agent, the Collateral Agent or a Lender of the full amount of the Obligation
Currency expressed to be payable to the applicable Administrative Agent, the
Collateral Agent or such Lender under this Agreement or the other Loan
Documents. If, for the purpose of obtaining or enforcing judgment against either
Borrower 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
                                                                    --------
Currency") an amount due in the Obligation Currency, the conversion shall be
--------
made, at the Exchange Rate, in the case of Canadian Dollars or U.S. Dollars,
and, in the case of other currencies, the rate of exchange (as quoted by the
Administrative Agent or if the Administrative Agent does not quote a rate of
exchange on such currency, by a known dealer in such currency designated by the
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 amount of any payment in the
Obligation Currency under this Section, the rate of exchange used shall take
into account any premium and costs payable in connection with the purchase of
the Obligation Currency.

     SECTION 11.18.  Certain Relationships.  Nothing contained in this
Agreement and no action taken by any Agent, the Administrative Agent or any
Lender pursuant hereto shall be deemed to constitute the Agents, the
Administrative Agent or the Lenders a partnership, an association, a joint
venture or other entity.  None of the Agents, the Administrative Agent or the
Lenders has any fiduciary relationship with or any fiduciary duty to either
Borrower arising out of or in connection with this Agreement or any of the other
Loan Documents, and the relationship between the Agents, the Administrative
Agent and the Lenders, on the one hand, and the Borrowers, on the other hand, in
connection herewith or therewith is solely that of debtor and creditor.
