28
-22-

acceptance and purchase of a Bankers' Acceptance hereunder shall constitute a
representation and warranty by the applicable Borrower(s) that the conditions
set forth in Section 11 and Section 12, as the case may be, have been satisfied
on the date of such request. Any unpaid Reimbursement Obligation shall be a
Base Rate Loan, Canadian Prime Rate Loan or Canadian Base Rate Loan hereunder,
as applicable, as set forth in Section 4.2(a).

SECTION 2.2. FACILITY FEE. The Company agrees to pay to the
Administrative Agent for the account of the Banks a fee (the "Facility Fee") on
the Total Commitment equal to the Applicable Facility Rate multiplied by the
Total Commitment. The Facility Fee shall be payable for the period from and
after the Closing Date quarterly in arrears on the first day of each calendar
quarter for the immediately preceding calendar quarter commencing on April 1,

SECTION 2.3. REDUCTION OF TOTAL COMMITMENT; INCREASE OF TOTAL
CANADIAN COMMITMENT.

(a) The Borrowers shall have the right at any time and from time to
time upon three (3) Business Days' prior written notice to the
Administrative Agent to reduce by $25,000,000 or a greater amount or
terminate entirely, the Total Commitment, whereupon each Bank's Commitment
shall be reduced pro rata in accordance with such Bank's Total Commitment
Percentage of the amount specified in such notice or, as the case may be,
terminated. Each of the Total Domestic Commitment and the Total Canadian
Commitment shall be reduced ratably in the event of such a reduction so that
no such reduction shall change the ratio of the Total Domestic Commitment to
the Total Canadian Commitment in effect immediately prior to such reduction
provided that at no time may (i) the Total Domestic Commitment be reduced to
an amount less than the sum of (A) the Maximum Drawing Amount of all
Domestic Letters of Credit, and (B) all Domestic Loans then outstanding, or
(ii) the Total Canadian Commitment be reduced to an amount less than the sum
of (A) the Maximum Drawing Amount of all Canadian Letters of Credit, (B) all
Canadian Loans then outstanding, and (C) the face amount of all outstanding
Bankers' Acceptances.

(b) No reduction or termination of the Total Commitment, the Total
Domestic Commitment or the Total Canadian Commitment once made may be
revoked; the portion of the Total Commitment, the Total Domestic Commitment
or the Total Canadian Commitment reduced or

29
-23-

terminated may not be reinstated; and amounts in respect of such reduced or
terminated portion may not be reborrowed.

(c) Subject to the satisfaction of the conditions precedent set
forth in paragraph (d) below, the Canadian Borrowers may increase the Total
Canadian Commitment in accordance with the following procedures; provided
that no reallocation of the Commitments of the Banks shall be permitted
unless (i) each Increased Bank and each Reduced Bank (each such term as
defined below) shall have agreed to such reallocation in writing, (ii) such
reallocation would not have the effect, together with any previous
reallocations hereunder, of increasing the Total Canadian Commitment to an
amount greater than U.S. $100,000,000, and (iii) the amount of the Total
Commitment shall not be increased by such reallocations. In the case of any
such reallocation, the Total Domestic Commitment shall be reduced by the
amount of the increase in the Total Canadian Commitment. Any such
reallocation shall be subject to execution of appropriate documentation with
respect thereto by the Borrowers, the Bank Agents, the Domestic Banks whose
Domestic Commitments are reduced pursuant to such reallocation (the "Reduced
Banks") and the Canadian Banks that will assume the increased Total Canadian
Commitment resulting from such reallocation (the "Increased Banks"). Each
Reduced Bank shall be an affiliate of an Increased Bank (with the increase
of such Increased Bank's Canadian Commitment being equal to the decrease of
its affiliate's Domestic Commitment). The Administrative Agent shall notify
the Banks of any such reallocation. The Canadian Commitments of the other
Canadian Banks which are not Increased Banks and the Domestic Commitments of
the other Domestic Banks which are not Reduced Banks shall not be changed by
any such reallocation.

(d) The consummation of any reallocation pursuant to paragraph (c)
above shall be subject to satisfaction of the following conditions on the
date of such consummation:

(i) in the case of the initial increase in the Total
Canadian Commitment, the Canadian Banks and the Canadian Borrowers, as
applicable, shall have executed appropriate joinders to this Agreement
and Canadian Notes, and delivered any other documentation requested by
the Canadian Agent, including without limitation an opinion of Canadian
counsel to the Canadian Borrowers if so requested;

(ii) all of the conditions to borrowing set forth in
Section 12 shall have been satisfied;

30
-24-

(iii) the Borrowers shall have given notice of such proposed
reallocation to the Bank Agents at least ten (10) Business Days in
advance of the requested date therefor;

(iv) such reallocation shall not result in the prepayment of
the Competitive Bid Loans, and, after giving effect to such
reallocation, (A) the aggregate principal amount of the Domestic Loans
outstanding plus the Maximum Drawing Amount of the outstanding Domestic
Letters of Credit shall not exceed the reduced Total Domestic
Commitment, (B) the aggregate principal amount of the Canadian Loans
outstanding plus the Maximum Drawing Amount of the outstanding Canadian
Letters of Credit and the aggregate face amount of all Bankers'
Acceptances (in each case expressed in U.S. Dollars) shall not exceed
the increased Total Canadian Commitment, and (C) the sum of the total
of clauses (A) and (B) (expressed in U.S. Dollars) shall not exceed the
Total Commitment; and

(v) each Increased Bank shall have received from the
Canadian Borrowers an applicable fee (the "Reallocation Fee") equal to
the greater of $2,500 or 1/16% of the amount of the increase in its
Canadian Commitment, as applicable.

(e) Subject to paragraph (d) above, the Canadian Agent shall
adjust the respective proportions of one or more of the Canadian Loans
funded by the Canadian Banks on or after the date of consummation of any
such reallocation in such a manner so that the sum of the outstanding
principal amount of all Canadian Loans of any Increased Bank plus such
Increased Bank's participations in the Canadian Letters of Credit plus the
aggregate face amount of all outstanding Bankers' Acceptances accepted by
such Canadian Bank shall equal such Canadian Bank's Canadian Commitment
Percentage (as modified) times the total outstandings under the Canadian
facility (as modified); provided that if the Canadian Agent shall not have
been able to achieve such equality within three months of said date of
consummation of any such reallocation for any reason, the Canadian Borrowers
shall forthwith prepay, subject to Section 6.8, one or more Canadian Loans,
and reborrow by way of one or more Canadian Loans, as the case may be, so as
to immediately achieve such equality.

(f) Subject to paragraph (d) above, the Administrative Agent shall
adjust the respective proportions of one or more of the Syndicated Loans
funded by the Domestic Banks on or after the date of consummation of any
such reallocation in such a manner so that the sum of the outstanding
principal amount of all Syndicated Loans of any Increased Bank plus such
Increased Bank's participations in the Domestic Letters of

31
-25-

Credit shall equal such Domestic Bank's Domestic Commitment Percentage (as
modified) times the total outstandings under the domestic facility (as
modified); provided that if the Administrative Agent shall not have been
able to achieve such equality within three months of said date of
consummation of any such reallocation for any reason, the Company shall
forthwith prepay, subject to Section 6.8, one or more Syndicated Loans, and
reborrow by way of one or more Syndicated Loans, as the case may be, so as
to immediately achieve such equality.

(g) The Administrative Agent will notify the Banks promptly after
receiving any notice delivered by the Borrowers pursuant to this Section 2.3
and will distribute to each Bank a revised schedule of Commitments, Domestic
Commitment Percentages and Canadian Commitment Percentages.

SECTION 2.4. THE SYNDICATED NOTES; THE CANADIAN NOTES.

(a) The Syndicated Loans shall be evidenced by separate promissory
notes of the Company in substantially the form of Exhibit A hereto (each, a
"Syndicated Note"), dated as of the Closing Date and completed with
appropriate insertions. One Syndicated Note shall be payable to the order
of each Domestic Bank in an amount equal to its Domestic Commitment, and
shall represent the obligation of the Company to pay such Domestic Bank such
principal amount or, if less, the outstanding principal amount of all
Syndicated Loans made by such Domestic Bank, plus interest accrued thereon,
as set forth herein.

(b) The Canadian Loans shall be evidenced by separate promissory
notes of the Canadian Borrowers in substantially the form of Exhibit C

Borrowers to pay such Canadian Bank such principal amount or, if less, the
outstanding principal amount of all Canadian Loans made by such Canadian
Bank, plus interest accrued thereon, as set forth herein.

(c) The applicable Borrower(s) irrevocably authorize each Bank to
make, or cause to be made, in connection with a Drawdown Date of any
Syndicated Loan or Canadian Loan, as the case may be, and at the time of
receipt of any payment of principal on any such Note, an appropriate
notation on such Bank's records or on the schedule attached to such Bank's
Note or a continuation of such schedule attached thereto reflecting the
making of such Loan, or the receipt of such payment (as the case may

32
-26-

be) and each Bank may, prior to any transfer of its Syndicated Note or
Canadian Note, as the case may be, endorse on the reverse side thereof the
outstanding principal amount of such Loans evidenced thereby. The
outstanding amount of the Loans set forth on such Bank's records shall be
prima facie evidence of the principal amount thereof owing and unpaid to
such Bank, but the failure to record, or any error in so recording, any such
amount shall not limit or otherwise affect the obligations of the applicable
Borrower(s) hereunder or under such Notes to make payments of principal of
or interest on any such Notes when due.

Default has occurred and is then continuing, the applicable Borrower(s) may
(i) elect to convert any Base Rate Loan or Canadian Base Rate Loan or a
portion thereof to a Eurodollar Loan, (ii) at the time of any Syndicated
Loan Request or Canadian Loan Request, specify that such requested Loan
shall be a Eurodollar Loan, or (iii) upon expiration of the applicable
Interest Period, elect to maintain an existing Eurodollar Loan as such,
provided that the applicable Borrower(s) give notice to the Administrative
Agent, in the case of Syndicated Loans, or the Canadian Agent, in the case
of Canadian Loans, pursuant to Section 2.7(b) hereof. Upon determining any
Eurodollar Rate, the Administrative Agent, in the case of Syndicated Loans,
and the Canadian Agent, in the case of Canadian Loans, shall forthwith
provide notice thereof to the applicable Borrower(s) and Bank(s), and each
such notice to such Borrower(s) shall be considered prima facie correct and
binding, absent manifest error.

(b) Three (3) Eurodollar Business Days prior to the making of any
Eurodollar Loan or the conversion of any Base Rate Loan to a Eurodollar
Loan, or, in the case of an outstanding Eurodollar Loan, the expiration date

the case of Syndicated Loans, or the Canadian Agent, in the case of Canadian
Loans, not later than 11:00 a.m. (New York time) of their election pursuant

or the Canadian Agent shall specify the aggregate principal amount of the
Syndicated Loans or Canadian Loans to be borrowed or maintained as or
converted to Eurodollar Loans and the requested duration of the Interest
Period that will be applicable to such Eurodollar Loan, and shall be
irrevocable and binding upon such Borrower(s). If the applicable
Borrower(s) shall fail to give the Administrative Agent or the Canadian
Agent, as applicable, notice of their

35
-29-

election hereunder together with all of the other information required by
this Section 2.7(b) with respect to any Syndicated Loan or Canadian Loan,
whether at the end of an Interest Period or otherwise, such Syndicated Loan
or Canadian Loan shall be deemed a Base Rate Loan or Canadian Base Rate
Loan, as the case may be. The Administrative Agent or the Canadian Agent,
as the case may be, shall promptly notify the applicable Bank(s) in writing
(or by telephone confirmed in writing or by facsimile) of such election.

(c) Notwithstanding anything herein to the contrary, the Borrowers
may not specify an Interest Period that would extend beyond the Maturity
Date.

(d) No conversion of Loans pursuant to this Section 2.7 may result
in Eurodollar Loans that are less than $5,000,000. In no event shall the
Borrowers have more than eight (8) different Interest Periods for borrowings
of Eurodollar Loans outstanding at any time.

(e) Subject to the terms and conditions of Section 6.8 hereof, if
any affected Bank demands compensation under Section 6.5(c) or (d) with
respect to any Eurodollar Loan, the applicable Borrower(s) may at any time,
upon at least three (3) Business Days' prior written notice to the
applicable Bank Agent, elect to convert such Eurodollar Loan into a Base
Rate Loan or Canadian Base Rate Loan, as applicable (on which interest and
principal shall be payable contemporaneously with the related Eurodollar
Loans of the other Banks). Thereafter, and until such time as the affected
Bank notifies the applicable Bank Agent that the circumstances giving rise
to the demand for compensation under Section 6.5(c) or (d) no longer exist,
all requests for Eurodollar Loans from such affected Bank shall be deemed to
be requests for Base Rate Loans or Canadian Base Rate Loans, as the case may
be. Once the affected Bank notifies the applicable Bank Agent that such
circumstances no longer exist, the Borrower(s) may elect that the principal
amount of each such Loan converted hereunder shall again bear interest as
Eurodollar Loans beginning on the first day of the next succeeding Interest
Period applicable to the related Eurodollar Loans of the other Banks.

SECTION 2.8. FUNDS FOR SYNDICATED LOANS AND CANADIAN LOANS. Not later
than 1:00 p.m. (New York time) on the proposed Drawdown Date (a) in the case of
Syndicated Loans, each of the Domestic Banks will make available to the
Administrative Agent or (b) in the case of Canadian Loans, each of the Canadian
Banks will made available to the Canadian Agent, at its respective Head Office,
in immediately available funds, the amount of its Domestic Commitment Percentage
or Canadian Commitment Percentage, as the case may be, of the amount of the
requested Loan. Upon receipt from each Bank of such amount,

36
-30-

and upon receipt of the documents required by Section 11 and Section 12 and the
satisfaction of the other conditions set forth therein, to the extent
applicable, the Administrative Agent will make available to the Company the
aggregate amount of such Syndicated Loans made available by the Domestic Banks,
and the Canadian Agent will make available to the Canadian Borrowers the
aggregate amount of such Canadian Loans made available by the Canadian Banks.
The failure or refusal of any Bank to make available to the applicable Bank
Agent at the aforesaid time and place on any Drawdown Date the amount of its
Domestic Commitment Percentage of the requested Syndicated Loan or its Canadian
Commitment Percentage of the requested Canadian Loan, as the case may be, shall
not relieve any other Bank from its several obligations hereunder to make
available to the applicable Bank Agent the amount of such Bank's Domestic
Commitment Percentage or Canadian Commitment Percentage, as the case may be, of
any requested Loan.

SECTION 2.9. MATURITY OF THE LOANS AND REIMBURSEMENT OBLIGATIONS. The
Loans shall be due and payable on the Maturity Date. The Company promises to
pay on the Maturity Date all Domestic Loans and all unpaid Reimbursement
Obligations on such date relating to Domestic Letters of Credit, and each of the
Canadian Borrowers, jointly and severally, promises to pay on the Maturity Date
all Canadian Loans, all unpaid Reimbursement Obligations relating to Canadian
Letters of Credit and all amounts owing with respect to Bankers' Acceptances.
All such payments shall be made together with any and all accrued and unpaid
interest thereon and any fees and other amounts owing hereunder.

SECTION 2.10. OPTIONAL PREPAYMENTS OR REPAYMENTS OF LOANS. Subject to
the terms and conditions of Section 6.8, the Borrowers shall have the right, at
their election, to repay or prepay the outstanding amount of the Loans, as a
whole or in part, at any time without penalty or premium. The applicable
Borrower(s) shall give the Administrative Agent or the Canadian Agent, as the
case may be, no later than 11:00 a.m. (New York time) (a) on the proposed date
of prepayment or repayment of Base Rate Loans, Canadian Base Rate Loans, and
Canadian Prime Rate Loans, and (b) one (1) Business Day prior to the proposed
date of prepayment or repayment of all other Loans, written notice (or
telephonic notice confirmed in writing or by facsimile) of any proposed
prepayment or repayment pursuant to this Section 2.10, specifying the proposed
date of prepayment or repayment of Loans and the principal amount to be paid.
Notwithstanding the foregoing, the Company may not prepay any Competitive Bid
Loans. The Administrative Agent shall promptly notify each Domestic Bank and
the Canadian Agent shall promptly notify each Canadian Bank by written notice
(or telephonic notice confirmed in writing or by facsimile) of such notice of
payment.

SECTION 2.11. SWING LINE LOANS; SETTLEMENTS.

(a) Solely for ease of administration of the Syndicated
Loans, MGT may, but shall not be required to, fund Base Rate Loans
made in accordance with the provisions of this Agreement ("Swing Line
Loans"). The Swing Line Loans shall be evidenced by a promissory note
of the Company in substantially the form of Exhibit B hereto (the
"Swing Line Note") and, at the discretion of MGT may be in amounts
less than $10,000,000 provided that the outstanding amount of Swing
Line Loans advanced by MGT hereunder shall not exceed $10,000,000 at
any time. Each Domestic Bank shall remain severally and
unconditionally liable to fund its pro rata share (based upon each
Domestic Bank's Domestic Commitment) of such Swing Line Loans on each
Swing Line Settlement Date and, in the event MGT chooses not to fund
all Base Rate Loans requested on any date, to fund its Domestic
Commitment Percentage of the Base Rate Loans requested, subject to
satisfaction of the provisions hereof relating to the making of Base
Rate Loans. Prior to each Swing Line Settlement, all payments or
repayments of the principal of, and interest on, Swing Line Loans
shall be credited to the account of MGT.

(b) The Domestic Banks shall effect Swing Line
Settlements on (i) the Business Day immediately following any day
which MGT gives written notice to the Administrative Agent to effect a
Swing Line Settlement, (ii) the Business Day immediately following the
Administrative Agent's becoming aware of the existence of any Default
or Event of Default, (iii) the Maturity Date and (iv) the Business Day
immediately following any day on which the outstanding amount of Swing
Line Loans advanced by MGT exceeds $10,000,000 (each such date, a
"Swing Line Settlement Date"). One (1) Business Day prior to each
such Swing Line Settlement Date, the Administrative Agent shall give
telephonic notice to the Domestic Banks of (A) the respective
outstanding amount of Syndicated Loans made by each Domestic Bank as
at the close of business on the prior day, (B) the amount that any
Domestic Bank, as applicable (a "Swing Line Settling Bank"), shall pay
to effect a Swing Line Settlement (a "Swing Line Settlement Amount")
and (C) the portion (if any) of the aggregate Swing Line Settlement
Amount to be paid to each Domestic Bank. A statement of the
Administrative Agent submitted to the Domestic Banks with respect to
any amounts owing hereunder shall be prima facie evidence of the
amount due and owing. Each Swing Line Settling Bank shall, not later
than 1:00 p.m. (New York time) on each Swing Line Settlement Date,
effect a wire transfer of immediately available funds to the
Administrative Agent at its Head Office in the amount of such Domestic
Bank's Swing Line Settlement Amount. The Administrative Agent shall,
as promptly as practicable during normal business hours on each Swing
Line Settlement Date, effect a wire transfer

38
-32-

of immediately available funds to each Domestic Bank of the Swing Line
Settlement Amount to be paid to such Domestic Bank. All funds advanced
by any Domestic Bank as a Swing Line Settling Bank pursuant to this
Section 2.11(b) shall for all purposes be treated as a Base Rate Loan
made by such Swing Line Settling Bank to the Company, and all funds
received by any Domestic Bank pursuant to this Section 2.11(b) shall
for all purposes be treated as repayment of amounts owed by the Company
with respect to Base Rate Loans made by such Domestic Bank.

(c) The Administrative Agent may (unless notified to the
contrary by any Swing Line Settling Bank by 12:00 noon (New York time)
one (1) Business Day prior to the Settlement Date) assume that each
Swing Line Settling Bank has made available (or will make available by
the time specified in Section 2.11(b)) to the Administrative Agent its
Swing Line Settlement Amount, and the Administrative Agent may (but
shall not be required to), in reliance upon such assumption, make
available to each applicable Domestic Bank its share (if any) of the
aggregate Swing Line Settlement Amount. If the Swing Line Settlement
Amount of such Swing Line Settling Bank is made available to the
Administrative Agent by such Swing Line Settling Bank on a date after
such Swing Line Settlement Date, such Swing Line Settling Bank shall
pay the Administrative Agent on demand an amount equal to the product
of (i) the average, computed for the period referred to in clause
(iii) below, of the weighted average annual interest rate paid by the
Administrative Agent for federal funds acquired by the Administrative
Agent during each day included in such period times (ii) such Swing
Line Settlement Amount times (iii) a fraction, the numerator of which
is the number of days that elapse from and including such Swing Line
Settlement Date to but not including the date on which such Swing Line
Settlement Amount shall become immediately available to the
Administrative Agent, and the denominator of which is 365. Upon
payment of such amount such Swing Line Settling Bank shall be deemed
to have delivered its Swing Line Settlement Amount on the Swing Line
Settlement Date and shall become entitled to interest payable by the
Company with respect to such Swing Line Settling Bank's Swing Line
Settlement Amount as if such share were delivered on the Swing Line
Settlement Date. If such Swing Line Settlement Amount is not in fact
made available to the Administrative Agent by such Swing Line Settling
Bank within three (3) Business Days of such Swing Line Settlement
Date, the Administrative Agent shall be entitled to recover such
amount from the Company, with interest thereon at the Base Rate.

(d) After any Swing Line Settlement Date, any payment by
the Company of Swing Line Loans hereunder shall be allocated among the
Domestic Banks, in amounts determined so as to provide that after such
application and the related Swing Line Settlement, the outstanding

39
-33-

amount of Syndicated Loans of each Domestic Bank equals, as nearly as
practicable, such Domestic Bank's Domestic Commitment Percentage of
the aggregate amount of Syndicated Loans.

Section 3. BANKERS' ACCEPTANCES.

SECTION 3.1. ACCEPTANCE AND PURCHASE. Subject to the terms and
conditions hereof, each Canadian Bank severally agrees to accept and purchase
Bankers' Acceptances drawn upon it by the Canadian Borrowers denominated in
Canadian Dollars. The Canadian Borrowers shall notify the Canadian Agent by
irrevocable written notice (each a "Bankers' Acceptance Notice") by 10:00 a.m.
(New York time) two (2) Business Days prior to the date of any borrowing by way
of Bankers' Acceptances. Each borrowing by way of Bankers' Acceptances shall be
in a minimum aggregate face amount of C$1,000,000 and integral multiples of
C$100,000 in excess thereof. The face amount of each Bankers' Acceptance shall
be C$100,000 or any integral multiple thereof. Each Bankers' Acceptance Notice
shall be in the form of Exhibit H. In no event shall the Dollar Equivalent of
the aggregate face amount of all outstanding Bankers' Acceptances exceed the
Total Canadian Commitment minus the sum of the outstanding principal amount of
all Canadian Loans (expressed in its Dollar Equivalent thereof), plus the
Maximum Drawing Amount (expressed in its Dollar Equivalent thereof) of all
outstanding Canadian Letters of Credit.

(a) Term. Bankers' Acceptances shall be issued and shall
mature on a Business Day. Each Bankers' Acceptance shall have a term
of 30, 60, 90 or 180 days and shall mature no later than five (5) days
prior to the Maturity Date and shall be in form and substance
reasonably satisfactory to the Canadian Bank which is accepting such
Bankers' Acceptance.

(b) Bankers' Acceptances in Blank. To facilitate the
acceptance of Bankers' Acceptances under this Agreement, the Canadian
Borrowers shall, upon execution of this Agreement and from time to
time as required, provide to the Canadian Agent drafts, in form
satisfactory to the Canadian Agent, duly executed and endorsed in
blank by the Canadian Borrowers in quantities sufficient for each
Canadian Bank to fulfill its obligations hereunder. In addition, the
Canadian Borrowers hereby appoint each Canadian Bank as its attorney
to sign and endorse on its behalf, in handwriting or by facsimile or
mechanical signature as and when deemed necessary by such Canadian
Bank, blank forms of Bankers' Acceptances. The Canadian Borrowers
recognize and agree that all Bankers' Acceptances signed and/or
endorsed on their behalf by a Canadian Bank shall bind the Canadian
Borrowers as fully and effectually as if signed in the handwriting of
and duly issued by the proper signing officers of the Canadian
Borrowers. Each Canadian Bank is hereby authorized to issue such
Bankers' Acceptances endorsed in blank

40
-34-

in such face amounts as may be determined by such Canadian Bank
provided that the aggregate amount thereof is equal to the aggregate
amount of Bankers' Acceptances required to be accepted by such Bank
pursuant to clause (d) below. No Canadian Bank shall be responsible or
liable for its failure to accept a Bankers' Acceptance if the cause of
such failure is, in whole or in part, due to the failure of the
Canadian Borrowers to provide duly executed and endorsed drafts to the
Canadian Agent on a timely basis nor shall any Canadian Bank or the
Canadian Agent be liable for any damage, loss or other claim arising by
reason of any loss or improper use of any such instrument except loss
or improper use arising by reason of the gross negligence or willful
misconduct of such Bank or the Canadian Agent, its officers, employees,
agents or representatives. Each Canadian Bank shall maintain a record
with respect to Bankers' Acceptances (A) received by it from the
Canadian Agent in blank hereunder, (B) voided by it for any reason, (C)
accepted by it hereunder, (D) purchased by it hereunder and (E)
cancelled at their respective maturities. Each Canadian Bank further
agrees to retain such records in the manner and for the statutory
periods provided in the various Canadian provincial or federal statutes
and regulations which apply to such Bank.

(c) Execution of Bankers' Acceptances. Drafts of the
Canadian Borrowers to be accepted as Bankers' Acceptances hereunder
shall be duly executed by one or more duly authorized officers on
behalf of the Canadian Borrowers. Notwithstanding that any person
whose signature appears on any Bankers' Acceptance as a signatory for
the Canadian Borrowers may no longer be an authorized signatory for
the Canadian Borrowers at the date of issuance of a Bankers'
Acceptance, such signature shall nevertheless be valid and sufficient
for all purposes as if such authority had remained in force at the
time of such issuance and any such Bankers' Acceptance so signed shall
be binding on the Canadian Borrowers.

(d) Issuance of Bankers' Acceptances. Promptly following
receipt of a Bankers' Acceptance Notice, the Canadian Agent shall so
advise the Canadian Banks of the face amount of each Bankers'
Acceptance to be accepted by it and the term thereof. The aggregate
face amount of Bankers' Acceptances to be accepted by a Canadian Bank
shall be determined by the Canadian Agent by reference to the
respective Canadian Commitments of the Canadian Banks, except that, if
the face amount of a Bankers' Acceptance, which would otherwise be
accepted by a Canadian Bank, would not be C$100,000 or an integral
multiple thereof, such face amount shall be increased or reduced by
the Canadian Agent in its sole and unfettered discretion to the
nearest integral multiple of C$100,000.

41
-35-

(e) Acceptances of Bankers' Acceptances. Each Bankers'
Acceptance to be accepted by a Canadian Bank shall be accepted at such
Bank's office shown on Schedule 2 hereof or as otherwise designated by
said Canadian Bank from time to time.

(f) Purchase of Bankers' Acceptances. On the relevant
date of borrowing, each Canadian Bank severally agrees to purchase
from the Canadian Borrowers, at the face amount thereof discounted by
the Applicable BA Discount Rate, any Bankers' Acceptance accepted by
it and provide to the Canadian Agent, for the account of the Canadian
Borrowers, the BA Discount Proceeds in respect thereof after deducting
therefrom the amount of the Acceptance Fee payable by the Canadian
Borrowers to such Bank under Section 3.3 in respect of such Bankers'
Acceptance.

(g) Sale of Bankers' Acceptances. Each Canadian Bank may
at any time and from time to time hold, sell, rediscount or otherwise
dispose of any or all Bankers' Acceptances accepted and purchased by
it.

(h) Waiver of Presentment and Other Conditions. Each of
the Canadian Borrowers waives presentment for payment and any other
defense to payment of any amounts due to a Canadian Bank in respect of
a Bankers' Acceptance accepted by such Canadian Bank pursuant to this
Agreement which might exist solely by reason of such Bankers'
Acceptance being held, at the maturity thereof, by such Bank in its
own right. The Canadian Borrowers shall not claim or require any days
of grace or require the Canadian Agent or any Canadian Bank to claim
any days of grace for the payment of any Bankers' Acceptance.

3.2. REFUNDING BANKERS' ACCEPTANCES. With respect to each Bankers'
Acceptance, the Canadian Borrowers, prior to the occurrence and continuation of
an Event of Default, may give irrevocable telephone or written notice (or such
other method of notification as may be agreed upon between the Canadian Agent
and the Canadian Borrowers) to the Canadian Agent at or before 2:00 p.m. (New
York time) two (2) Business Days prior to the maturity date of such Bankers'
Acceptance followed by written confirmation electronically transmitted to the
Canadian Agent on the same day, of the Canadian Borrowers' intention to issue
one or more Bankers' Acceptances on such maturity date (each a "Refunding
Bankers' Acceptance") to provide for the payment of such maturing Bankers'
Acceptance (it being understood that payments by the Canadian Borrowers and
fundings by the Canadian Banks in respect of each maturing Bankers' Acceptance
and each related Refunding Bankers' Acceptance shall be made on a net basis
reflecting the difference between the face amount of such maturing Bankers'
Acceptance and the BA Discount Proceeds (net of the applicable Acceptance Fee)
of such Refunding Bankers' Acceptance). Any funding on

42
-36-

account of any maturing Bankers' Acceptance must be made at or before 12:00 noon
(New York time) on the maturity date of such Bankers' Acceptance. If the
Canadian Borrowers fail to give such notice, the Canadian Borrowers shall be
irrevocably deemed to have requested and to have been advanced a Canadian Prime
Rate Loan in the face amount of such maturing Bankers' Acceptance on the
maturity date of such maturing Bankers' Acceptance from the Canadian Bank which
accepted such maturing Bankers' Acceptance, which Canadian Prime Rate Loan shall
thereafter bear interest as such in accordance with the provisions hereof and
otherwise shall be subject to all provisions of this Agreement applicable to
Canadian Prime Rate Loans until paid in full.

SECTION 3.3. ACCEPTANCE FEE. An acceptance fee (the "Acceptance Fee")
shall be payable by the Canadian Borrowers to each Canadian Bank and each
Canadian Bank shall deduct the amount of such Acceptance Fee from the BA
Discount Proceeds (in the manner specified in Section 3.1(f) in respect of each
Bankers' Acceptance), said fee to be calculated at a rate per annum equal to the
Applicable L/C Rate calculated on the face amount of such Bankers' Acceptance
and computed on the basis of the number of days in the term of such Bankers'
Acceptance and a year of 365 days.

SECTION 3.4. CASH COLLATERAL. Subject to Section 30, upon the
occurrence and during the continuance of any Event of Default, and in addition
to any other rights or remedies of any Canadian Bank and the Canadian Agent
hereunder, any Canadian Bank or the Canadian Agent as and by way of collateral
security (or such alternate arrangement as may be agreed upon by the Canadian
Borrowers and such Canadian Bank or the Canadian Agent, as applicable) shall be
entitled to deposit and retain in an account to be maintained by the Canadian
Agent (bearing interest at the Canadian Agent's rates as may be applicable in
respect of other deposits of similar amounts for similar terms) amounts which
are received by such Canadian Bank or the Canadian Agent from the Canadian
Borrowers hereunder or as proceeds of the exercise of any rights or remedies of
any Canadian Bank or the Canadian Agent hereunder against the Canadian
Borrowers, to the extent such amounts may be required to satisfy any contingent
or unmatured obligations or liabilities of the Canadian Borrowers to the
Canadian Banks or the Canadian Agent, or any of them hereunder.

SECTION 4. LETTERS OF CREDIT.

SECTION 4.1. LETTER OF CREDIT COMMITMENTS.

(a) Subject to the terms and conditions hereof and the
receipt of a Letter of Credit Application by the Issuing Bank, with a
copy to the Administrative Agent in the case of Domestic Letters of
Credit and to the Canadian Agent in the case of Canadian Letters of
Credit, reflecting the Maximum Drawing Amount of all Domestic Letters
of Credit or Canadian

43
-37-

Letters of Credit, as applicable (including the requested Letter of
Credit), the Issuing Bank, on behalf of the Domestic Banks in the case
of Domestic Letters of Credit or the Canadian Banks in the case of
Canadian Letters of Credit, and in reliance upon the representations
and warranties of the Borrowers contained herein and the agreement of
the Banks contained in Section 4.1(b) hereof, agrees to issue Domestic
Letters of Credit for the account of the Company or Canadian Letters of
Credit for the account of the Canadian Borrowers, as applicable (which
may incorporate automatic renewals for periods of up to twelve (12)
months), in such form as may be requested from time to time by such
Borrower(s) and agreed to by the Issuing Bank; provided, however, that,
after giving effect to such request, (i) the aggregate Maximum Drawing
Amount of all Domestic Letters of Credit issued at any time shall not
exceed the lesser of (A) $500,000,000 or (B) the Total Domestic
Commitment minus the aggregate outstanding amount of the Domestic
Loans, and (ii) the aggregate Maximum Drawing Amount of Canadian
Letters of Credit issued at any time shall not exceed the Total
Canadian Commitment less the sum of all outstanding Canadian Loans and
the aggregate face amount of all outstanding Bankers' Acceptances, and
provided further, that no Letter of Credit shall have an expiration
date later than the earlier of (x) eighteen (18) months after the date
of issuance (which may incorporate automatic renewals for periods of up
to twelve (12) months), or (y) five (5) Business Days prior to the
Maturity Date. The letters of credit listed in Schedule 4.1(a) issued
by Issuing Banks under the Original Credit Agreement shall be Letters
of Credit under this Agreement.

(b) Each Domestic Letter of Credit shall be denominated
in Dollars, and each Canadian Letter of Credit shall be denominated in
Canadian Dollars or Dollars, at the option of the Canadian Borrowers.
With respect to any request for a Canadian Letter of Credit
denominated in Canadian Dollars, the Canadian Agent shall calculate
the U.S. Dollar Equivalent of the Maximum Drawing Amount of such
requested Canadian Letter of Credit and shall notify the Canadian
Borrowers and the Administrative Agent of the results of such
calculation. Such U.S. Dollar Equivalent of the Maximum Drawing
Amount shall be used to determine compliance with the provisions of
Section 4.1(a) and in any other calculation of compliance with
Canadian Commitments and the Total Canadian Commitment.

(c) Each Domestic Bank with respect to Domestic Letters
of Credit and each Canadian Bank with respect to Canadian Letters of
Credit severally agrees that it shall be absolutely liable, without
regard to the occurrence of any Default or Event of Default, the
termination of the Total Commitment pursuant to Section 13.2, or any
other condition precedent whatsoever, to the extent of such Bank's
Domestic Commitment

44
-38-

Percentage or Canadian Commitment Percentage, as applicable, to
reimburse the Issuing Bank on demand for the amount of each draft paid
by the Issuing Bank under each Domestic Letter of Credit or Canadian
Letter of Credit, as applicable, to the extent that such amount is not
reimbursed by the applicable Borrower(s) pursuant to Section 4.2 (such
agreement for a Bank being called herein the "Letter of Credit
Participation" of such Bank). Each Bank agrees that its obligation to
reimburse the Issuing Bank pursuant to this Section 4.1(c) shall not be
affected in any way by any circumstance other than the gross negligence
or willful misconduct of the Issuing Bank.

(d) Each such reimbursement payment made by a Bank to the
Issuing Bank shall be treated as the purchase by such Bank of a
participating interest in the applicable Reimbursement Obligation
under Section 4.2 in an amount equal to such payment. Each Bank shall
share in accordance with its participating interest in any interest
which accrues pursuant to Section 4.2.

SECTION 4.2. REIMBURSEMENT OBLIGATION OF THE BORROWERS. In order to
induce the Issuing Banks to issue, extend and renew each Letter of Credit, (i)
the Company hereby agrees to reimburse or pay to each Issuing Bank, with respect
to each Domestic Letter of Credit issued, extended or renewed by such Issuing
Bank hereunder, and (ii) each of the Canadian Borrowers hereby jointly and
severally agrees to reimburse or pay to each Issuing Bank, with respect to each
Canadian Letter of Credit issued, extended or renewed by such Issuing Bank
hereunder, as follows:

(a) if any draft presented under any Letter of Credit is
honored by such Issuing Bank or such Issuing Bank otherwise makes
payment with respect thereto, the sum of (i) the amount paid by such
Issuing Bank under or with respect to such Letter of Credit, and (ii)
the amount of any taxes, fees, charges or other costs and expenses
whatsoever incurred by such Issuing Bank in connection with any
payment made by such Issuing Bank under, or with respect to, such
Letter of Credit, provided however, if the applicable Borrower(s) do
not reimburse such Issuing Bank on the Drawdown Date, such amount
shall become automatically a Syndicated Loan which is a Base Rate Loan
or a Canadian Loan which is a Canadian Base Rate Loan or Canadian
Prime Rate Loan, as applicable, advanced hereunder in an amount equal
to such sum; and

(b) upon the Maturity Date or the acceleration of the
Reimbursement Obligations with respect to all Letters of Credit in
accordance with Section 13, an amount equal to the then Maximum
Drawing Amount of (i) all Domestic Letters of Credit shall be paid by
the Company to the Administrative Agent and (ii) all Canadian Letters
of Credit shall

45
-39-

be paid by the Canadian Borrowers to the Canadian Agent, in each case
to be held as cash collateral for the applicable Reimbursement
Obligations.

SECTION 4.3. OBLIGATIONS ABSOLUTE. The Borrowers' respective
obligations under this Section 4 shall be absolute and unconditional under any
and all circumstances and irrespective of the occurrence of any Default or Event
of Default or any condition precedent whatsoever or any setoff, counterclaim or
defense to payment which the Borrowers may have or have had against any Issuing
Bank, any Bank or any beneficiary of a Letter of Credit, and each of the
Borrowers expressly waives any such rights that it may have with respect
thereto. The Borrowers further agree with each Issuing Bank and the Banks that
such Issuing Bank and the Banks (i) shall not be responsible for, and the
Borrowers' respective Reimbursement Obligations under Section 4.2 shall not be
affected by, among other things, the validity or genuineness of documents or of
any endorsements thereon, even if such documents should in fact prove to be in
any or all respects invalid, fraudulent or forged (unless due to the willful
misconduct of such Issuing Bank or any other Bank), or any dispute between or
among the Borrowers and the beneficiary of any Letter of Credit or any financing
institution or other party to which any Letter of Credit may be transferred or
any claims or defenses whatsoever of the Borrowers against the beneficiary of
any Letter of Credit or any such transferee, and (ii) shall not be liable for
any error, omission, interruption or delay in transmission, dispatch or delivery
of any message or advice, however transmitted, in connection with any Letter of
Credit except to the extent of their own willful misconduct. The Borrowers
agree that any action taken or omitted by any Issuing Bank or any Bank in good
faith under or in connection with any Letter of Credit and the related drafts
and documents shall be binding upon the applicable Borrower(s) and shall not
result in any liability on the part of such Issuing Bank or any Bank (or their
respective affiliates) to the Borrowers. Nothing herein shall constitute a
waiver by the Borrowers of any of their rights against any beneficiary of a
Letter of Credit.

SECTION 4.4. RELIANCE BY THE ISSUING BANKS. To the extent not
inconsistent with Section 4.3, each Issuing Bank shall be entitled to rely, and
shall be fully protected in relying, upon any Letter of Credit, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, facsimile, telex or teletype message, statement, order or other
document believed by such Issuing Bank in good faith to be genuine and correct
and to have been signed, sent or made by the proper Person or Persons and upon
advice and statements of legal counsel, independent accountants and other
experts selected by such Issuing Bank.

SECTION 4.5. NOTICE REGARDING LETTERS OF CREDIT. One (1) Business Day
prior to the issuance of any Letter of Credit or amendments or extensions
thereof, the applicable Issuing Bank shall notify the Administrative Agent or
the Canadian

46
-40-

Agent, as applicable, of the terms of such Letter of Credit, amendment or
extension. On the day of any drawing under any Letter of Credit, such Issuing
Bank shall notify the Administrative Agent or the Canadian Agent, as applicable,
of such drawing under any Letter of Credit.

SECTION 4.6. LETTER OF CREDIT FEE. The Company, in the case of Domestic
Letters of Credit, and the Canadian Borrowers jointly and severally, in the case
of Canadian Letters of Credit, shall pay a fee (the "Letter of Credit Fee")
equal to the Applicable L/C Rate on the Maximum Drawing Amount of applicable
Letters of Credit issued hereunder to the Administrative Agent or the Canadian
Agent, as applicable, for the account of the Banks, to be shared pro rata by
each of such Banks in accordance with their respective Domestic Commitment
Percentages or Canadian Commitment Percentages, as applicable. The Letter of
Credit Fee shall be payable quarterly in arrears on the first day of each
calendar quarter for the quarter just ended, commencing April 1, 1997, and on
the Maturity Date. In addition, an issuing fee (the "Issuance Fee") to be
agreed upon annually between the applicable Borrower(s) and an Issuing Bank
shall be payable to such Issuing Bank for its account.

SECTION 5. COMPETITIVE BID LOANS.

SECTION 5.1. THE COMPETITIVE BID OPTION. In addition to the
Syndicated Loans made pursuant to Section 2 hereof, the Company may request
Competitive Bid Loans pursuant to the terms of this Section 5. The Domestic
Banks may, but shall have no obligation to, make such offers and the Company
may, but shall have no obligation to, accept such offers in the manner set forth
in this Section 5. Notwithstanding any other provision herein to the contrary,
at no time shall the aggregate principal amount of Competitive Bid Loans
outstanding at any time exceed the lesser of (i) the Total Domestic Commitment
minus the sum of (a) the aggregate outstanding principal amount of Syndicated
Loans (including the Swing Loans), plus (b) the Maximum Drawing Amount of
Domestic Letters of Credit outstanding at such time, or (ii) $500,000,000.

SECTION 5.2. COMPETITIVE BID LOAN ACCOUNTS: COMPETITIVE BID NOTES.

(a) The obligation of the Company to repay the
outstanding principal amount of any and all Competitive Bid Loans,
plus interest at the applicable Competitive Bid Rate accrued thereon,
shall be evidenced by this Agreement and by individual loan accounts
(the "Competitive Bid Loan Accounts" and individually, a "Competitive
Bid Loan Account") maintained by the Administrative Agent on its books
for each of the Domestic Banks, it being the intention of the parties
hereto that, except as provided for in paragraph (b) of this Section
5.2, the Company's obligations with respect to Competitive Bid Loans
are to be evidenced only as stated herein and not by separate
promissory notes.

47
-41-

(b) Any Domestic Bank may at any time, and from time to
time, request that any Competitive Bid Loans outstanding to such
Domestic Bank be evidenced by a promissory note of the Company in
substantially the form of Exhibit D hereto (each, a "Competitive Bid
Note"), dated as of the Closing Date and completed with appropriate
insertions. One Competitive Bid Note shall be payable to the order of
each Domestic Bank in an amount equal to $500,000,000, and
representing the obligation of the Company to pay such Domestic Bank
such principal amount or, if less, the outstanding principal amount of
any and all Competitive Bid Loans made by such Domestic Bank, plus
interest at the applicable Competitive Bid Rate or Competitive Bid
Margin accrued thereon, as set forth herein. Upon execution and
delivery by the Company of a Competitive Bid Note, the Company's
obligation to repay any and all Competitive Bid Loans made to it by
such Domestic Bank and all interest thereon shall thereafter be
evidenced by such Competitive Bid Note.

(c) The Company irrevocably authorizes (i) each Domestic
Bank to make or cause to be made, in connection with a Drawdown Date
of any Competitive Bid Loan or at the time of receipt of any payment
of principal on such Domestic Bank's Competitive Bid Note in the case
of a Competitive Bid Note, and (ii) the Administrative Agent to make
or cause to be made, in connection with a Drawdown Date of any
Competitive Bid Loan or at the time of receipt of any payment of
principal on such Domestic Bank's Competitive Bid Loan Account in the
case of a Competitive Bid Loan Account, an appropriate notation on
such Domestic Bank's records or on the schedule attached to such
Domestic Bank's Competitive Bid Note or a continuation of such
schedule attached thereto, or the Administrative Agent's records, as
applicable, reflecting the making of the Competitive Bid Loan or the
receipt of such payment (as the case may be) and such Domestic Bank
may, prior to any transfer of a Competitive Bid Note, endorse on the
reverse side thereof the outstanding principal amount of Competitive
Bid Loans evidenced thereby. The outstanding amount of the
Competitive Bid Loans set forth on such Domestic Bank's record or the
Administrative Agent's records, as applicable, shall be prima facie
evidence of the principal amount thereof owing and unpaid to such
Domestic Bank, but the failure to record, or any error in so
recording, any such amount shall not limit or otherwise affect the
obligations of the Company hereunder to make payments of principal of
or interest on any Competitive Bid Loan when due.

SECTION 5.3. COMPETITIVE BID QUOTE REQUEST; INVITATION FOR COMPETITIVE
BID QUOTES.

(a) When the Company wishes to request offers to make
Competitive Bid Loans under this Section 5, it shall transmit to the

has notified the Administrative Agent of its acceptance or
non-acceptance of the Competitive Bid Quotes relating to any
outstanding Competitive Bid Quote Request.

(b) Promptly upon receipt of a Competitive Bid Quote
Request, the Administrative Agent shall send to the Domestic Banks by
telecopy or facsimile transmission an Invitation for Competitive Bid

SECTION 5.4. ALTERNATIVE MANNER OF PROCEDURE. If, after receipt by the
Administrative Agent and each of the Domestic Banks of a Competitive Bid Quote
Request from the Company in accordance with Section 5.3, the Administrative
Agent or any Domestic Bank shall be unable to complete any procedure of the
auction process described in Sub Section 5.5 through 5.6 (inclusive) due to
the inability of such Person to transmit or receive communications through the
means specified therein, such Person may rely on telephonic notice for the
transmission or receipt of such communications. In any case where such Person
shall rely on telephone transmission or receipt, any communication made by
telephone shall, as soon as possible thereafter, be followed by written

SECTION 5.5. SUBMISSION AND CONTENTS OF COMPETITIVE BID QUOTES.

(a) Each Domestic Bank may, but shall be under no
obligation to, submit a Competitive Bid Quote containing an offer or
offers to make Competitive Bid Loans in response to any Competitive

case of an Absolute Competitive Bid Loan, provided that Competitive
Bid Quotes may be submitted by the Administrative Agent in its
capacity as a Domestic Bank only if it submits its Competitive Bid
Quote to the Company not later than (x) one hour prior to the deadline
for the other Domestic Banks, in the case of a LIBOR Competitive Bid
Loan or (y) 15 minutes prior to the deadline for the other Domestic
Banks, in the case of an Absolute Competitive Bid Loan. Subject to

Bid Quote so made shall be irrevocable except with the written consent
of the Administrative Agent given on the instructions of the Company.

(b) Each Competitive Bid Quote shall be in substantially the
form of Exhibit M hereto and shall in any case specify:

(i) the proposed Drawdown Date;

(ii) the principal amount of the Competitive Bid

or a larger multiple of $1,000,000, (y) may not exceed the
aggregate principal amount of Competitive Bid Loans for which
offers were requested and (z) may be subject to an aggregate

for which offers being made by such quoting Domestic Bank may

(iii) the Interest Period(s) for which Competitive
Bid Quotes are being submitted;

(iv) in the case of a LIBOR Competitive Bid Loan,
the margin above or below the applicable LIBOR Rate (the

Rate;

50
-44-

(v) in the case of an Absolute Competitive Bid Loan,
the rate of interest per annum (specified to the nearest
1/10,000th of 1%) (the "Competitive Bid Rate") offered for
each such Absolute Competitive Bid Loan; and

(vi) the identity of the quoting Domestic Bank.

A Competitive Bid Quote may include up to five separate offers by the
quoting Domestic Bank with respect to each Interest Period specified
in the related Invitation for Competitive Bid Quotes.

(i) is not substantially in the form of Exhibit M
hereto;

(ii) contains qualifying, conditional or similar
language;

(iii) proposes terms other than or in addition to
those set forth in the applicable Invitation for Competitive
Bid Quotes; or

(iv) arrives after the time set forth in Section
5.5(a) hereof.

SECTION 5.6. NOTICE TO COMPANY. The Administrative Agent shall
promptly notify the Company of the terms (x) of any Competitive Bid Quote
submitted by a Domestic Bank that is in accordance with Section 5.5 and (y) of
any Competitive Bid Quote that amends, modifies or is otherwise inconsistent
with a previous Competitive Bid Quote submitted by such Domestic Bank with
respect to the same Competitive Bid Quote Request. Any such subsequent
Competitive Bid Quote shall be disregarded by the Administrative Agent unless
such subsequent Competitive Bid Quote is submitted solely to correct a manifest
error in such former Competitive Bid Quote. The Administrative Agent's notice
to the Company shall specify (A) the aggregate principal amount of Competitive
Bid Loans for which offers have been received for each Interest Period specified
in the related Competitive Bid Quote Request, (B) the respective principal
amounts and Competitive Bid Margins or Competitive Bid Rates, as the case may
be, so offered, and the identity of the respective Domestic Banks submitting
such offers, and (C) if applicable, limitations on the aggregate principal
amount of Competitive Bid Loans for which offers in any single Competitive Bid
Quote may be accepted.

SECTION 5.7. ACCEPTANCE AND NOTICE BY COMPANY AND ADMINISTRATIVE AGENT.
Not later than 11:00 a.m. (New York time) on (x) the third Eurodollar Business
Day prior to the proposed Drawdown Date, in the case of a LIBOR Competitive Bid
Loan or (y) the proposed Drawdown Date, in the case of an Absolute Competitive
Bid Loan, the Company shall notify the Administrative Agent of its acceptance or
non-acceptance of each Competitive Bid Quote in

51
-45-

substantially the form of Exhibit N hereto. The Company may accept any
Competitive Bid Quote in whole or in part; provided that:

(i) the aggregate principal amount of each Competitive Bid
Loan may not exceed the applicable amount set forth in the related
Competitive Bid Quote Request;

(ii) acceptance of offers may only be made on the basis of
ascending Competitive Bid Margins or Competitive Bid Rates, as the
case may be, and

(iii) the Company may not accept any offer that is described
in subsection 5.5(c) or that otherwise fails to comply with the
requirements of this Agreement.

The Administrative Agent shall promptly notify each Domestic Bank which
submitted a Competitive Bid Quote of the Company's acceptance or non-
acceptance thereof. At the request of any Domestic Bank which submitted a
Competitive Bid Quote and with the consent of the Company, the Administrative
Agent will promptly notify all Domestic Banks which submitted Competitive Bid
Quotes of (a) the aggregate principal amount of, and (b) the range of
Competitive Bid Rates or Competitive Bid Margins of, the accepted Competitive
Bid Loans for each requested Interest Period.

SECTION 5.8. ALLOCATION BY ADMINISTRATIVE AGENT. If offers are made by
two or more Domestic Banks with the same Competitive Bid Margin or Competitive
Bid Rate, as the case may be, for a greater aggregate principal amount than the
amount in respect of which offers are accepted for the related Interest Period,
the principal amount of Competitive Bid Loans in respect of which such offers
are accepted shall be allocated by the Administrative Agent among such Domestic
Banks as nearly as possible (in such multiples, not less than $1,000,000, as the
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determination by the Administrative Agent of
the amounts of Competitive Bid Loans shall be conclusive in the absence of
manifest error.

SECTION 5.9. FUNDING OF COMPETITIVE BID LOANS. If, on or prior to the
Drawdown Date of any Competitive Bid Loan, the Total Domestic Commitment has not
terminated in full and if, on such Drawdown Date, the applicable conditions of
Sub Section 11 and 12 hereof are satisfied, the Domestic Bank or Domestic
Banks whose offers the Company has accepted will fund each Competitive Bid Loan
so accepted. Such Domestic Bank or Domestic Banks will make such Competitive
Bid Loans by crediting the Administrative Agent for further credit to the
Company's specified account with the Administrative Agent, in immediately
available funds not later than 1:00 p.m. (New York time) on such Drawdown Date.

52
-46-

SECTION 5.10. FUNDING LOSSES. If, after acceptance of any Competitive
Bid Quote pursuant to Section 5, the Company (i) fails to borrow any Competitive
Bid Loan so accepted on the date specified therefor, or (ii) repays the
outstanding amount of the Competitive Bid Loan prior to the last day of the
Interest Period relating thereto, the Company shall indemnify the Domestic Bank
making such Competitive Bid Quote or funding such Competitive Bid Loan against
any loss or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Domestic Bank to fund or maintain such
unborrowed Loans, including, without limitation compensation as provided in
Section 6.8.

SECTION 5.11. REPAYMENT OF COMPETITIVE BID LOANS; INTEREST. The
principal of each Competitive Bid Loan shall become absolutely due and payable
by the Company on the last day of the Interest Period relating thereto, and the
Company hereby absolutely and unconditionally promises to pay to the
Administrative Agent for the account of the relevant Domestic Banks at or before
1:00 p.m. (New York time) on the last day of the Interest Periods relating
thereto the principal amount of all such Competitive Bid Loans, plus interest
thereon at the applicable Competitive Bid Rates. The Competitive Bid Loans
shall bear interest at the rate per annum specified in the applicable
Competitive Bid Quotes. Interest on the Competitive Bid Loans shall be payable
(a) on the last day of the applicable Interest Periods, and if any such Interest
Period is longer than three months, also on the last day of the third month
following the commencement of such Interest Period, and (b) on the Maturity Date
for all Loans. Subject to the terms of this Agreement, the Company may make
Competitive Bid Quote Requests with respect to new borrowings of any amounts so
repaid prior to the Maturity Date.

SECTION 6. PROVISIONS RELATING TO ALL LOANS AND LETTERS OF CREDIT.

SECTION 6.1. PAYMENTS.

(a) All payments of principal, interest, Reimbursement
Obligations, fees (other than the Issuance Fee and the Acceptance Fee)
and any other amounts due hereunder or under any of the other Loan
Documents shall be made to the Administrative Agent or the Canadian
Agent, as applicable, received at the applicable Head Office in
immediately available funds by 11:00 a.m. (New York time) on any due
date. Subject to the provisions of Section 30, if a payment is
received by such Bank Agent at or before 1:00 p.m. (New York time) on
any Business Day, such Bank Agent shall on the same Business Day
transfer in immediately available funds, as applicable, to (1) each of
the Domestic Banks, their pro rata portion of such payment in
accordance with their respective Domestic Commitment Percentages, in
the case of payments with respect to

53
-47-

Syndicated Loans and Domestic Letters of Credit, (2) MGT in the case
of payments with respect to Swing Line Loans (3) each of the Canadian
Banks, their pro rata portion of such payment in accordance with their
respective Canadian Commitment Percentages, in the case of Canadian
Loans and Canadian Letters of Credit, and (4) the appropriate Domestic
Bank(s), in the case of payments with respect to Competitive Bid
Loans. If such payment is received by such Bank Agent after 1:00 p.m.
(New York time) on any Business Day, such transfer shall be made by
such Bank Agent to the applicable Bank(s) on the next Business Day.
In the event that such Bank Agent fails to make such transfer to any
Bank as set forth above, such Bank Agent shall pay to such Bank on
demand an amount equal to the product of (i) the average, computed for
the period referred to in clause (iii) below, of the weighted average
interest rate paid by such Bank for funds acquired by such Bank during
each day included in such period, times (ii) the amount (A) equal to
such Bank's Domestic Commitment Percentage of such payment in the case
of payments under clause (1) above, (B) equal to such Bank's Canadian
Commitment Percentage of such payment in the case of payments under
clause (3) above or (C) of such payment to which such Bank is entitled
in the case of payments with respect to Competitive Bid Loans and
Swing Line Loans, times (iii) a fraction, the numerator of which is
the number of days that elapse from and including the date of payment
to and including the date on which the amount due to such Bank shall
become immediately available to such Bank, and the denominator of
which is 365. A statement of such Bank submitted to the applicable
Bank Agent with respect to any amounts owing under this paragraph
shall be prima facie evidence of the amount due and owing to such Bank
by such Bank Agent.

(b) Each Domestic Bank that is not incorporated or
organized under the laws of the United States of America or a state
thereof or the District of Columbia (a "Non-U.S. Bank") agrees that,
prior to the first date on which any payment is due to it hereunder,
it will deliver to the Company and the Documentation Agent two duly
completed copies of United States Internal Revenue Service Form 1001
or 4224 or successor applicable form, as the case may be, certifying
in each case that such Non-U.S. Bank is entitled to receive payments
under this Agreement and the Notes payable to it, without deduction or
withholding of any United States federal income taxes. Each Non-U.S.
Bank that so delivers a Form 1001 or 4224 pursuant to the preceding
sentence further undertakes to deliver to each of the Company and the
Documentation Agent two further copies of Form 1001 or 4224 or
successor applicable form, or other manner of certification, as the
case may be, on or before the date that any such letter or form
expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form previously delivered by it
to the Company, and such extensions or renewals thereof as may

54
-48-

reasonably be requested by the Company, certifying in the case of a
Form 1001 or 4224 that such Non-U.S. Bank is entitled to receive
payments under this Agreement and the Notes without deduction or
withholding of any United States federal income taxes, unless in any
such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any
such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Non-U.S. Bank from duly
completing and delivering any such form with respect to it and such
Non-U.S. Bank advises the Company that it is not capable of receiving
payments without any deduction or withholding of United States federal
income tax.

(c) The Company shall not be required to pay any
additional amounts to any Non-U.S. Bank in respect of United States
Federal withholding tax pursuant to Section 18 to the extent that (i)
the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Bank became
a party to this Credit Agreement or, with respect to payments to a
different lending office designated by the Non-U.S. Bank as its
applicable lending office (a "New Lending Office"), the date such
Non-U.S. Bank designated such New Lending Office with respect to a
Loan; provided, however, that this clause (i) shall not apply to any
transferee or New Lending Office as a result of an assignment,
transfer or designation made at the request of the Company; and
provided further, however, that this clause (i) shall not apply to the
extent the indemnity payment or additional amounts any transferee, or
Bank through a New Lending Office, would be entitled to receive
without regard to this clause (i) do not exceed the indemnity payment
or additional amounts that the Person making the assignment or
transfer to such transferee, or Bank making the designation of such
New Lending Office, would have been entitled to receive in the absence
of such assignment, transfer or designation; or (ii) the obligation to
pay such additional amounts would not have arisen but for a failure by
such Non-U.S. Bank to comply with the provisions of paragraph (c)
above.

(d) Notwithstanding the foregoing, each Bank agrees to use
reasonable efforts (consistent with legal and regulatory restrictions)
to change its lending office to avoid or to minimize any amounts
otherwise payable under Section 18 in each case solely if such change
can be made in a manner so that such Bank, in its sole determination,
suffers no legal, economic or regulatory disadvantage.

(e) Payments of principal or interest with respect to any
Loan, unpaid Reimbursement Obligation or obligation with respect to
Bankers' Acceptances shall be made in the currency in which such Loan
was advanced or in which such Letter of Credit or Bankers' Acceptance
was

55
-49-

issued. Notwithstanding the foregoing, any and all fees payable
hereunder (other than Issuance Fees with respect to Letters of Credit
issued in C$) shall be payable solely in US$.

SECTION 6.2. MANDATORY REPAYMENTS OF THE LOANS. If at any time (i) the
sum of the outstanding principal amount of the Domestic Loans plus the Maximum
Drawing Amount of all outstanding Domestic Letters of Credit exceeds the Total
Domestic Commitment, whether by reduction of the Total Domestic Commitment or
otherwise, or (ii) the sum of the outstanding principal amount of the Canadian
Loans plus the Maximum Drawing Amount of all outstanding Canadian Letters of
Credit plus the aggregate face amount of all outstanding Bankers' Acceptances
exceeds the Total Canadian Commitment, then the Company shall immediately pay
the amount of such excess to the Administrative Agent in the case of clause (i)
above, or the Canadian Borrowers, jointly and severally, shall immediately pay
the amount of such excess to the Canadian Agent, in the case of clause (ii)
above, (a) for application to the Loans, in the case of clause (i) above, first
to Syndicated Loans, then to Competitive Bid Loans, subject to Section 6.8, or
(b) if no Loans shall be outstanding, to be held by the Administrative Agent or
the Canadian Agent, as the case may be for the benefit of the Banks as
collateral security for such excess Maximum Drawing Amount and/or borrowings by
way of Bankers' Acceptances; provided, however, that if the amount of cash
collateral held by the Administrative Agent or the Canadian Agent pursuant to
this Section 6.2 exceeds the Maximum Drawing Amount and/or borrowings by way of
Bankers' Acceptances required to be collateralized from time to time, such Bank
Agent shall return such excess to the applicable Borrower(s).

SECTION 6.3. COMPUTATIONS. (a) Except as otherwise expressly provided
herein, all computations of interest, Facility Fees, Letter of Credit
Fees or other fees shall be based on a 360-day year and paid for the
actual number of days elapsed, except that computations based on the
Administrative Agent's "prime rate", Canadian Prime Rate and Canadian
Base Rate shall be based on a 365 or 366, as applicable, day year and
paid for the actual number of days elapsed. Whenever a payment
hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day, and interest shall accrue
during such extension; provided that for any Interest Period for any
Eurodollar Loan if such next succeeding Business Day falls in the next
succeeding calendar month or after the Maturity Date, it shall be
deemed to end on the next preceding Business Day.

(b) All computations of outstanding Loans, Commitment
availability, mandatory prepayments, or other matters hereunder shall
be made in US$ or Dollar Equivalents.

56
-50-

SECTION 6.4. ILLEGALITY; INABILITY TO DETERMINE EURODOLLAR RATE.
Notwithstanding any other provision of this Agreement (other than
Section 6.10), if (a) the introduction of, any change in, or any change in the
interpretation of, any law or regulation applicable to any Bank or the
Administrative Agent or the Canadian Agent shall make it unlawful, or any
central bank or other governmental authority having jurisdiction thereof shall
assert that it is unlawful, for any Bank or any such Bank Agent to perform its
obligations in respect of any Eurodollar Loans, or (b) if any Bank or any such
Bank Agent, as applicable, shall reasonably determine with respect to
Eurodollar Loans that (i) by reason of circumstances affecting any Eurodollar
interbank market, adequate and reasonable methods do not exist for ascertaining
the Eurodollar Rate which would otherwise be applicable during any Interest
Period, or (ii) deposits of Dollars in the relevant amount for the relevant
Interest Period are not available to such Bank or such Bank Agent in any
Eurodollar interbank market, or (iii) the Eurodollar Rate does not or will not
accurately reflect the cost to such Bank or such Bank Agent of obtaining or
maintaining the applicable Eurodollar Loans during any Interest Period, then
such Bank or such Bank Agent shall promptly give telephonic, telex or cable
notice of such determination to the applicable Borrower(s) (which notice shall
be conclusive and binding upon such Borrower(s)). Upon such notification by
such Bank or such Bank Agent, the obligation of the Banks and such Bank Agent
to make Eurodollar Loans shall be suspended until the Banks or such Bank Agent,
as the case may be, determine that such circumstances no longer exist, and to
the extent permitted by law the outstanding Eurodollar Loans shall continue to
bear interest at the applicable rate based on the Eurodollar Rate until the end
of the applicable Interest Period, and thereafter shall be deemed converted to
Base Rate Loans or Canadian Base Rate Loans, as applicable, in equal principal
amounts to such former Eurodollar Loans.

SECTION 6.5. ADDITIONAL COSTS, ETC. If any present or future applicable
law (which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank by any central bank or other fiscal, monetary or
other authority, whether or not having the force of law) shall:

(a) subject such Bank to any tax, levy, impost, duty,
charge, fee, deduction or withholding of any nature with respect to
this Agreement, the other Loan Documents, such Bank's Domestic
Commitment or Canadian Commitment, or the Loans (other than taxes
based upon or measured by the income or profits of such Bank imposed
by the jurisdiction of its incorporation or organization, or the
location of its lending office); or

57
-51-

(b) materially change the basis of taxation (except for
changes in taxes on income or profits of such Bank imposed by the
jurisdiction of its incorporation or organization, or the location of
its lending office) of payments to such Bank of the principal or of
the interest on any Loans or any other amounts payable to such Bank
under this Agreement or the other Loan Documents; or

(c) except as provided in Section 6.6 or as otherwise
reflected in the Base Rate, Canadian Base Rate, Canadian Prime Rate,
the Eurodollar Rate, or the Competitive Bid Rate, impose or increase
or render applicable (other than to the extent specifically provided
for elsewhere in this Agreement) any special deposit, reserve,
assessment, liquidity, capital adequacy or other similar requirements
(whether or not having the force of law) against assets held by, or
deposits in or for the account of, or loans by, or commitments of, an
office of any Bank with respect to this Agreement, the other Loan
Documents, such Bank's Domestic Commitment or Canadian Commitment, or
the Loans; or

(d) impose on such Bank any other conditions or
requirements with respect to this Agreement, the other Loan Documents,
the Loans, such Bank's Domestic Commitment or Canadian Commitment, as
applicable, or any class of loans or commitments of which any of the
Loans or such Bank's Domestic Commitment or Canadian Commitment, as
applicable, forms a part, and the result of any of the foregoing is:

(i) to increase the cost to such Bank of making,
funding, issuing, renewing, extending or maintaining the Loans
or such Bank's Domestic Commitment or Canadian Commitment, as
applicable, or issuing or participating in Letters of Credit,
or accepting and purchasing Bankers' Acceptances;

(ii) to reduce the amount of principal, interest
or other amount payable to such Bank hereunder on account of
such Bank's Domestic Commitment, Canadian Commitment or the
Loans, the Reimbursement Obligations or Bankers' Acceptances;
or

(iii) to require such Bank to make any payment or
to forego any interest or other sum payable hereunder, the
amount of which payment or foregone interest or other sum is
calculated by reference to the gross amount of any sum
receivable or deemed received by such Bank from the Borrowers
hereunder,

then, and in each such case, the Canadian Borrowers, in the
case of Canadian Loans, Canadian Letters of Credit and Bankers'
Acceptances, and the Company, in each other case, will, upon demand
made by such Bank at any time and from time to time as often as the
occasion therefore

58
-52-

may arise (which demand shall be accompanied by a
statement setting forth the basis of such demand which shall be
conclusive absent manifest error), pay such reasonable additional
amounts as will be sufficient to compensate such Bank for such
additional costs, reduction, payment or foregone interest or other
sum.

SECTION 6.6. CAPITAL ADEQUACY. If any Bank shall have determined that,
after the date hereof, the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change in any such law, rule, or regulation,
or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of such Bank (or any corporation controlling such
Bank) as a consequence of such Bank's obligations hereunder to a level below
that which such Bank (or any corporation controlling such Bank) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank, the Canadian Borrowers, in the case of Canadian Banks, and the
Company in the case of the Domestic Banks, shall pay to such Bank such
additional amount or amounts as will, in such Bank's reasonable determination,
fairly compensate such Bank (or any corporation controlling such Bank) for such
reduction. Each Bank shall allocate such cost increases among its customers in
good faith and on an equitable basis.

SECTION 6.7. CERTIFICATE. A certificate setting forth the additional
amounts payable pursuant to Section 6.5 or Section 6.6 and a reasonable
explanation of such amounts which are due, submitted by any Bank to the
applicable Borrower(s), shall be conclusive, absent manifest error, that such
amounts are due and owing.

SECTION 6.8. EURODOLLAR AND COMPETITIVE BID INDEMNITY. The Company
agrees to indemnify the Domestic Banks and the Administrative Agent, and the
Canadian Borrowers agree to indemnify the Canadian Banks and the Canadian Agent,
and to hold them harmless from and against any reasonable loss, cost or expense
that any such Bank and such Bank Agent may sustain or incur as a consequence of
(a) the default by such Borrower(s) in payment of the principal amount of or any
interest on any Eurodollar Loans or Competitive Bid Loans as and when due and
payable, including any such loss or expense arising from interest or fees
payable by any Bank or such Bank Agent to lenders of funds obtained by it in
order to maintain its Eurodollar Loans or Competitive Bid Loans, (b) the default
by such Borrower(s) in making a borrowing of a Eurodollar Loan or Competitive
Bid Loan or conversion of a Eurodollar Loan or a prepayment of a Eurodollar or
Competitive Bid Loan other than on an Interest

59
-53-

Payment Date after such Borrower(s) has given (or is deemed to have given) a
Syndicated Loan Request, a notice pursuant to Section 2.7 or a Notice of
Acceptance/Rejection of Competitive Bid Quote(s), or a notice pursuant to
Section 2.10, and (c) the making of any payment of a Eurodollar Loan or
Competitive Bid Loan, or the making of any conversion of any Eurodollar Loan to
a Base Rate Loan or Canadian Base Rate Loan, as applicable, or the reallocation
of any Eurodollar Loan pursuant to Section 2.3(d) or Section 2.3(e) on a day
that is not the last day of the applicable Interest Period with respect thereto.
Such loss, cost, or reasonable expense shall include an amount equal to the
excess, if any, as reasonably determined by each Bank of (i) its cost of
obtaining the funds for (A) the Eurodollar Loan being paid, prepaid, converted,
not converted, reallocated, or not borrowed, as the case may be (based on the
Eurodollar Rate), or (B) the Competitive Bid Loan being paid, prepaid, or not
borrowed, as the case may be (based on the Competitive Bid Rate) for the period
from the date of such payment, prepayment, conversion, or failure to borrow or
convert, as the case may be, to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for the Loan
which would have commenced on the date of such failure to borrow) over (ii) the
amount of interest (as reasonably determined by such Bank) that would be
realized by such Bank in reemploying the funds so paid, prepaid, converted, or
not borrowed, converted, or prepaid for such period or Interest Period, as the
case may be, which determinations shall be conclusive absent manifest error.

SECTION 6.9. INTEREST ON OVERDUE AMOUNTS. Overdue principal and (to the
extent permitted by applicable law) interest on the Loans and all other overdue
amounts payable hereunder or under any of the other Loan Documents shall bear
interest compounded monthly and payable on demand at a rate per annum equal to
the Base Rate, Canadian Base Rate or Canadian Prime Rate, as applicable, plus
2%, until such amount shall be paid in full (after as well as before judgment).

SECTION 6.10. INTEREST LIMITATION.

(a) Notwithstanding any other term of this Agreement or
the Notes, any other Loan Document or any other document referred to
herein or therein, the maximum amount of interest which may be charged
to or collected from any Person liable hereunder or under the Notes by
any Bank shall be absolutely limited to, and shall in no event exceed,
the maximum amount of interest which could lawfully be charged or
collected by such Bank under applicable laws (including, to the extent
applicable, the provisions of Section 5197 of the Revised Statutes of
the United States of America, as amended, 12 U.S.C. Section 85, as
amended, and the Criminal Code (Canada)).

60
-54-

(b) With respect to Canadian Loans, whenever interest is
payable hereunder on the basis of a year of 360 days, for the purposes
of the Interest Act (Canada), the yearly rate of interest which is
equivalent to the rate payable hereunder is the rate payable hereunder
multiplied by the actual number of days in the year and divided by
360. All interest will be calculated using the nominal rate method
and not the effective rate method and the deemed reinvestment
principle shall not apply to such calculations.

SECTION 6.11. REASONABLE EFFORTS TO MITIGATE. Each Bank agrees that as
promptly as practicable after it becomes aware of the occurrence of an event or
the existence of a condition that would cause it to be affected under
Sections 6.4, 6.5 or 6.6, such Bank will give notice thereof to the applicable
Borrower(s), with a copy to the Administrative Agent or the Canadian Agent, as
applicable, and, to the extent so requested by such Borrower(s) and not
inconsistent with such Bank's internal policies, such Bank shall use reasonable
efforts and take such actions as are reasonably appropriate if as a result
thereof the additional moneys which would otherwise be required to be paid to
such Bank pursuant to such sections would be materially reduced, or the
illegality or other adverse circumstances which would otherwise require a
conversion of such Loans or result in the inability to make such Loans pursuant
to such sections would cease to exist, and in each case if, as determined by
such Bank in its sole discretion, the taking such actions would not adversely
affect such Loans or such Bank or otherwise be disadvantageous to such Bank.

SECTION 6.12. REPLACEMENT OF BANKS. If any Bank (an "Affected Bank")
(i) makes demand upon the Borrowers for (or if Borrowers are otherwise required
to pay) amounts pursuant to Sections 6.5 or 6.6, (ii) is unable to make or
maintain Eurodollar Loans as a result of a condition described in Section 6.4 or
(iii) defaults in its obligation to make Loans, participate in Letters of Credit
and/or, in the case of the Canadian Banks, accept and purchase Bankers'
Acceptances, in accordance with the terms of this Agreement (such Bank being
referred to as a "Defaulting Bank"), the Borrowers may, within 90 days of
receipt of such demand, notice (or the occurrence of such other event causing
the Borrowers to be required to pay such compensation or causing Section 6.4 to
be applicable), or default, as the case may be, by notice (a "Replacement
Notice") in writing to the Bank Agents and such Affected Bank (A) request the
Affected Bank to cooperate with the Borrowers in obtaining a replacement bank
satisfactory to the Bank Agents and the Borrowers (the "Replacement Bank"); (B)
request the non-Affected Banks to acquire and assume all of the Affected Bank's
Loans and Commitment, participate in Letters of Credit and/or, in the case of
the Canadian Banks, accept and purchase Bankers' Acceptances, as provided
herein, but none of such Banks shall be under an obligation to do so; or (C)
designate a Replacement Bank reasonably satisfactory to the Bank Agents. If any
satisfactory Replacement Bank shall be obtained, and/or any of the non-Affected

61
-55-

Banks shall agree to acquire and assume all of the Affected Bank's Loans and
Commitment, participate in Letters of Credit and/or, in the case of the Canadian
Banks, accept and purchase Bankers' Acceptances, then such Affected Bank shall,
so long as no Event of Default shall have occurred and be continuing, assign, in
accordance with Section 20, all of its Commitment, Loans, Notes and other rights
and obligations under this Agreement and all other Loan Documents to such
Replacement Bank or non-Affected Banks, as the case may be, in exchange for
payment of the principal amount so assigned and all interest and fees accrued on
the amount so assigned, plus all other Obligations then due and payable to the
Affected Bank; provided, however, that (x) such assignment shall be without
recourse, representation or warranty and shall be on terms and conditions
reasonably satisfactory to such Affected Bank and such Replacement Bank and/or
non-Affected Banks, as the case may be, and (y) prior to any such assignment,
the applicable Borrower(s) shall have paid to such Affected Bank all amounts
properly demanded and unreimbursed under Sections 6.5, 6.6 and 6.8. Upon
the effective date of such assignment, the Canadian Borrowers, in the case of
Canadian Banks, and the Company, in all other cases, shall issue replacement
Notes to such Replacement Bank and/or non-Affected Banks, as the case may be,
and such Replacement Bank shall become a "Bank" for all purposes under this
Agreement and the other Loan Documents.

SECTION 6.13. ADVANCES BY ADMINISTRATIVE AGENT AND CANADIAN AGENT. The
Administrative Agent or the Canadian Agent, as applicable, may
(unless earlier notified to the contrary by any Bank by 12:00 noon (New York
time) one (1) Business Day prior to any Drawdown Date) assume that each Bank
has made available (or will before the end of such Business Day make available)
to such Bank Agent the amount of such Bank's Domestic Commitment Percentage or
Canadian Commitment Percentage, as applicable, with respect to the Loans (or,
in the case of Competitive Bid Loans, the amount of such Domestic Bank's
accepted offers of such Loans, if any) to be made on such Drawdown Date, and
such Bank Agent may (but shall not be required to), in reliance upon such
assumption, make available to the applicable Borrower(s) a corresponding
amount. If any Bank makes such amount available to such Bank Agent on a date
after such Drawdown Date, such Bank shall pay such Bank Agent on demand an
amount equal to the product of (i) the average, computed for the period
referred to in clause (iii) below, of the weighted average annual interest rate
paid by such Bank Agent for federal funds acquired by such Bank Agent, or
corresponding Canadian funds in the case of the Canadian Agent, during each day
included in such period times (ii) the amount equal to such Bank's Domestic
Commitment Percentage of such Syndicated Loan and Canadian Commitment
Percentage of such Canadian Loan, as applicable (or, in the case of Competitive
Bid Loans and Swing Line Loans, the amount of such Domestic Bank's accepted
offer of such Competitive Bid Loans, if any, and portion of such Swing Line
Loans) times (iii) a fraction, the numerator of which is the number of days
that elapse from and including such Drawdown Date to

62
-56-

but not including the date on which the amount equal to such Bank's Domestic
Commitment Percentage or Canadian Commitment Percentage, as applicable, of such
Loans, or the amount of such Domestic Bank's accepted offers of such Competitive
Bid Loans, if any, and portion of Swing Line Loans, shall become immediately
available to such Bank Agent, and the denominator of which is 365. A statement
of such Bank Agent submitted to such Bank with respect to any amounts owing
under this paragraph shall be prima facie evidence of the amount due and owing
to such Bank Agent by such Bank. If such amount is not in fact made available
to such Bank Agent by such Bank within three (3) Business Days of such Drawdown
Date, such Bank Agent shall be entitled to recover such amount from such
Borrower(s), with interest thereon at the applicable rate per annum.

SECTION 6.14. CURRENCY FLUCTUATIONS.

(a) Not later than 1:00 p.m. (New York time) on the last
Business Day of each calendar month (the "Calculation Date"), the
Administrative Agent shall determine the Exchange Rate as of such
date. The Exchange Rate so determined shall become effective on the
first Business Day immediately following such determination (a "Reset
Date") and shall remain effective until the next succeeding Reset
Date.

(b) Not later than 4:00 p.m. (New York time) on each
Reset Date, the Administrative Agent shall consult with the Canadian
Agent to determine the Dollar Equivalent of the outstanding Canadian
Loans, Bankers' Acceptances and Canadian Letters of Credit denominated
in Canadian Dollars.

(c) If, on any Reset Date and on the Maturity Date, the
aggregate outstanding amount (expressed in U.S. Dollars) of all
Canadian Loans, the Maximum Drawing Amount with respect to Canadian
Letters of Credit, and the aggregate face amount of all outstanding
Bankers' Acceptances exceeds the Total Canadian Commitment by more
than $100,000, then (i) the Canadian Agent shall give notice thereof
to the Canadian Borrowers and the Canadian Banks and (ii) within two
(2) Business Days thereafter, the Canadian Borrowers shall repay or
prepay Canadian Loans in accordance with this Agreement in an
aggregate principal amount such that, after giving effect thereto, the
aggregate outstanding amount (expressed in U.S. Dollars) of all
Canadian Loans, the Maximum Drawing Amount with respect to Canadian
Letters of Credit and the aggregate face amount of all outstanding
Bankers' Acceptances no longer exceeds the Total Canadian Commitment
(expressed in U.S. Dollars).

63
-57-

(d) Without limiting subsection 6.14(c), if, on
any day prior to the Maturity Date, the aggregate outstanding amount
(expressed in U.S. Dollars) of all Canadian Loans, the Maximum Drawing
Amount with respect to Canadian Letters of Credit and the aggregate
face amount of all outstanding Bankers' Acceptances exceeds the Total
Canadian Commitment by five percent (5%) or more, then (i) the
Canadian Agent shall give notice thereof to the Canadian Borrowers and
the Canadian Banks and (ii) within two (2) Business Days thereafter,
the Canadian Borrowers shall repay or prepay Canadian Loans in
accordance with this Agreement in an aggregate principal amount such
that, after giving effect thereto, the aggregate outstanding amount
(expressed in U.S. Dollars) of all Canadian Loans, the Maximum Drawing
Amount with respect to Canadian Letters of Credit and the aggregate
face amount of all outstanding Bankers' Acceptances no longer exceeds
the Total Canadian Commitment (expressed in U.S. Dollars). Nothing
set forth in this Section 6.14 shall be construed to require any Bank
Agent to calculate daily compliance under this Section 6.14 unless
expressly requested to do so by a Bank.

(e) To the extent the repayments and prepayments
referenced in Section 6.14(c) and Section 6.14(d) are such that, after
giving effect thereto, the Maximum Drawing Amount with respect to
Canadian Letters of Credit and the aggregate face amount of all
outstanding Bankers' Acceptances (expressed in U.S. Dollars) still
exceeds the Total Canadian Commitment (expressed in U.S. Dollars),
then the Canadian Borrowers shall immediately upon demand provide cash
collateral to the Canadian Agent required to obtain such results.

SECTION 7. REPRESENTATIONS AND WARRANTIES. Each of the Borrowers (and
Sanifill, where identified by name) represents and warrants to the Banks that:

Subsidiaries as a whole.

64
-58-

(b) Authorization. The execution, delivery and
performance of its Loan Documents and the transactions contemplated

the Borrowers and Sanifill, (ii) have been duly authorized by all
necessary corporate proceedings on the part of each of the Borrowers
and Sanifill, (iii) do not conflict with or result in any breach or

is subject or any judgment, order, writ, injunction, license or permit
applicable to any of the Borrowers, Sanifill or any such Subsidiary so
as to materially adversely affect the assets, business or any activity
of any of the Borrowers, Sanifill and their Subsidiaries as a whole,
and (iv) do not conflict with any provision of the corporate charter
or bylaws of any of the Borrowers, Sanifill or any Subsidiary or any
agreement or other instrument binding upon any of the Borrowers,
Sanifill or any of their Subsidiaries.

(c) Enforceability. The execution, delivery and
performance of the Loan Documents by each of the Borrowers and
Sanifill will result in valid and legally binding obligations of each
of the Borrowers and Sanifill enforceable against it in accordance
with the respective terms and provisions hereof and thereof, except as
enforceability is limited by bankruptcy, insolvency, reorganization,
moratorium or other laws relating to or affecting generally the
enforcement of creditors' rights and except to the extent that
availability of the remedy of specific performance or injunctive
relief is subject to the discretion of the court before which any
proceeding therefor may be brought.

SECTION 7.2. GOVERNMENTAL APPROVALS. The execution, delivery and
performance of the Loan Documents by each of the Borrowers and Sanifill and the
consummation by each of the Borrowers and Sanifill of the transactions
contemplated hereby and thereby do not require any approval or consent of, or
filing with, any governmental agency or authority other than those already
obtained and those required after the date hereof in connection with the
Company's and its Subsidiaries' performance of their covenants contained in
Section Section 8, 9 and 10 hereof.

SECTION 7.3. TITLE TO PROPERTIES; LEASES. The Company and its
Subsidiaries own all of the assets reflected in the consolidated balance sheet

65

SECTION 7.4. FINANCIAL STATEMENTS; SOLVENCY.

(a) There have been furnished to the Banks consolidated
balance sheets of the Company and its Subsidiaries and Sanifill and
its Subsidiaries dated the Balance Sheet Date and consolidated
statements of operations for the fiscal periods then ended, certified

Banks consolidated balance sheets of the Company and its Subsidiaries
dated the Interim Balance Sheet Date and the related consolidated
statements of operation for the period of three (3) consecutive fiscal
quarters ending on the Interim Balance Sheet Date. All said balance
sheets and statements of operations have been prepared in accordance
with GAAP (but, in the case of any of such financial statements which
are unaudited, only to the extent GAAP is applicable to interim
unaudited reports), fairly present the financial condition of the
Company and its Subsidiaries or Sanifill and its Subsidiaries, on a
consolidated basis, as at the close of business on the dates thereof
and the results of operations for the periods then ended, subject, in
the case of unaudited interim financial statements, to changes
resulting from audit and normal year-end adjustments and to the
absence of complete footnotes. There are no contingent liabilities of
the Company and its Subsidiaries or Sanifill and its Subsidiaries
involving material amounts, known to the officers of the Company and
Sanifill which have not been disclosed in said balance sheets and the
related notes thereto or otherwise in writing to the Banks.

(b) The Company and its Subsidiaries on a consolidated
basis (both before and after giving effect to the transactions
contemplated by this Agreement including the Mid-American Acquisition
and the Allied Acquisition) are solvent (i.e., they have assets having
a fair value in excess of the amount required to pay their probable
liabilities on their existing debts as they become absolute and
matured) and have, and expect to have, the ability to pay their debts
from time to time incurred in connection therewith as such debts
mature.

SECTION 7.5. NO MATERIAL CHANGES, ETC. Since the Interim Balance Sheet
Date, there have occurred no material adverse changes in the consolidated
financial condition, business or assets of the Company and its Subsidiaries,
taken together, or Sanifill and its Subsidiaries, taken together, as the case
may be, as shown on or reflected in the consolidated balance sheets of the
Company and its Subsidiaries or Sanifill and its Subsidiaries as at the Interim
Balance Sheet Date, or the consolidated statements of income for the period then
ended other than changes in the ordinary course of business which have not had
any material adverse effect either individually or in the aggregate on the
financial condition, business or assets of the Company and its Subsidiaries,
taken together, or Sanifill and its Subsidiaries, taken together, as the case
may be.

66
-60-

Since the Interim Balance Sheet Date, there have not been any Distributions
(including Distributions by the Company or Sanifill) other than as permitted by
Section 9.5 hereof.

SECTION 7.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. The Company and each
of its Subsidiaries possess all franchises, patents, copyrights, trademarks,
trade names, licenses and permits, and rights in respect of the foregoing,
adequate for the conduct of their business substantially as now conducted (other
than those the absence of which would not have a material adverse effect on the
business, operations or financial condition of the Company and its Subsidiaries
as a whole) without known conflict with any rights of others other than a
conflict which would not have a material adverse effect on the financial
condition, business or assets of the Company and its Subsidiaries as a whole.

SECTION 7.7. LITIGATION. Except as set forth on Schedule 7.7, there are
no actions, suits, proceedings or investigations of any kind pending or, to the
knowledge of the Company or any of its Subsidiaries, threatened against the
Company or any of its Subsidiaries before any court, tribunal or administrative
agency or board which, either in any case or in the aggregate, could reasonably
be expected to have a material adverse effect on the financial condition,
business, or assets of the Company and its Subsidiaries, considered as a whole,
or materially impair the right of the Company and its Subsidiaries, considered
as a whole, to carry on business substantially as now conducted, or result in
any substantial liability not adequately covered by insurance, or for which
adequate reserves are not maintained on the consolidated balance sheet or which
question the validity of any of the Loan Documents to which the Company or any
of its Subsidiaries is a party, or any action taken or to be taken pursuant
hereto or thereto.

SECTION 7.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Company
nor any of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Company's or such Subsidiary's officers has or could reasonably
be expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Company and its Subsidiaries, considered as
a whole. Neither the Company nor any of its Subsidiaries is a party to any
contract or agreement which in the judgment of the Company's or its Subsidiary's
officers has or could reasonably be expected to have any materially adverse
effect on the financial condition, business or assets of the Company and its
Subsidiaries, considered as a whole, except as otherwise reflected in adequate
reserves as required by GAAP.

SECTION 7.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the
Company nor any of its Subsidiaries is (a) violating any provision of its
charter documents or by-laws or (b) any agreement or instrument to which any of
them may be subject or by which any of them

67
-61-

or any of their properties may be bound or any decree, order, judgment, or any
statute, license, rule or regulation, in a manner which could (in the case of
such agreements or such instruments) reasonably be expected to result in the
imposition of substantial penalties or materially and adversely affect the
financial condition, business or assets of the Company and its Subsidiaries,
considered as a whole.

SECTION 7.10. TAX STATUS. The Company and its Subsidiaries have filed
all federal, state, provincial and territorial income and all other tax returns,
reports and declarations (or obtained extensions with respect thereto) required
by applicable law to be filed by them (unless and only to the extent that the
Company or such Subsidiary has set aside on its books provisions reasonably
adequate for the payment of all unpaid and unreported taxes as required by
GAAP); and have paid all taxes and other governmental assessments and charges
(other than taxes, assessments and other governmental charges imposed by
jurisdictions other than the United States, Canada or any political subdivision
thereof which in the aggregate are not material to the financial condition,
business or assets of the Company or such Subsidiary on an individual basis or
of the Company and its Subsidiaries on a consolidated basis) that are material
in amount, shown or determined to be due on such returns, reports and
declarations, except those being contested in good faith; and, as required by
GAAP, have set aside on their books provisions reasonably adequate for the
payment of all taxes for periods subsequent to the periods to which such
returns, reports or declarations apply. Except to the extent contested in the
manner permitted in the preceding sentence, there are no unpaid taxes in any
material amount claimed by the taxing authority of any jurisdiction to be due
and owing by the Company or any Subsidiary, nor do the officers of the Company
or any of its Subsidiaries know of any basis for any such claim.

SECTION 7.11. NO EVENT OF DEFAULT. No Default or Event of Default has
occurred and is continuing.

SECTION 7.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the
Company nor any of its Subsidiaries is a "holding company", or a "subsidiary
company" of a "holding company", or an "affiliate" of a "holding company", as
such terms are defined in the Public Utility Holding Company Act of 1935; nor is
any of them a "registered investment company", or an "affiliated company" or a
"principal underwriter" of a "registered investment company", as such terms are
defined in the Investment Company Act of 1940, as amended.

SECTION 7.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except as
permitted by Section 9.2 of this Agreement, there is no Indebtedness senior
to the Obligations, and there is no effective financing statement, security
agreement, chattel mortgage, real estate mortgage or other document filed or
recorded with any filing records, registry, or other public office, which
purports to cover, affect or give notice of

68
-62-

any present or possible future lien on, or security interest in, any assets or
property of the Company or any of its Subsidiaries or right thereunder.

SECTION 7.14. EMPLOYEE BENEFIT PLANS.

(a) In General. Each Employee Benefit Plan has been
maintained and operated in compliance in all material respects with
the provisions of ERISA and/or all Applicable Canadian Pension
Legislation, as applicable, and, to the extent applicable, the Code,
including but not limited to the provisions thereunder respecting
prohibited transactions.

(b) Terminability of Welfare Plans. Under each Employee
Benefit Plan which is an employee welfare benefit plan within the
meaning of Section 3(1) or Section 3 (2)(B) of ERISA, no benefits are
due unless the event giving rise to the benefit entitlement occurs
prior to plan termination (except as required by Title I, part 6 of
ERISA.) The Company, each of its Subsidiaries, or ERISA Affiliate, as
appropriate, may terminate each such plan at any time (or at any time
subsequent to the expiration of any applicable bargaining agreement)
in the discretion of Company or such Subsidiary, or ERISA Affiliate
without material liability to any Person.

(c) Guaranteed Pension Plans. Neither the Company nor
any of its Subsidiaries is a sponsor of, or contributor to, a
Guaranteed Pension Plan.

(d) Multiemployer Plans. Neither the Company, any of its
Subsidiaries, nor any ERISA Affiliate has incurred any material
liability (including secondary liability) to any Multiemployer Plan as
a result of a complete or partial withdrawal from such Multiemployer
Plan under Section 4201 of ERISA or as a result of a sale of assets
described in Section 4204 of ERISA. Neither the Company, any of its
Subsidiaries, nor any ERISA Affiliate has been notified that any
Multiemployer Plan is in reorganization or is insolvent under and
within the meaning of Section 4241 or Section 4245 of ERISA or that
any Multiemployer Plan intends to terminate or has been terminated
under Section 4041A of ERISA.

SECTION 7.15. ENVIRONMENTAL COMPLIANCE. The Company and its
Subsidiaries have taken all necessary steps to investigate the past and present
condition and usage of the Real Property and the operations conducted by the
Company and its Subsidiaries and, based upon such diligent investigation, have
determined that, except as set forth on Schedule 7.15:

(a) Neither the Company, its Subsidiaries, nor any
operator of their properties, is in violation, or alleged violation,
of any judgment, decree, order, law, permit, license, rule or
regulation pertaining to

environmental matters, including without limitation, those arising
under the Resource Conservation and Recovery Act ("RCRA"), the
Comprehensive Environmental Response, Compensation and Liability Act of
1980 as amended ("CERCLA"), the Superfund Amendments and
Reauthorization Act of 1986 ("XXXX"), the Federal Clean Water Act, the
Federal Clean Air Act, the Toxic Substances Control Act, or any United
States or Canadian federal, state, provincial, territorial or local
statute, regulation, ordinance, order or decree relating to health,
safety, waste transportation or disposal, or the environment (the
"Environmental Laws"), which violation would have a material adverse
effect on the business, assets or financial condition of the Company
and its Subsidiaries on a consolidated basis.

(b) Except as described on Schedule 7.15, neither the
Company nor any of its Subsidiaries has received notice from any third
party including, without limitation: any federal, state, provincial,
territorial or local governmental authority, (i) that any one of them
has been identified by the United States Environmental Protection
Agency ("EPA") as a potentially responsible party under CERCLA with
respect to a site listed on the National Priorities List, 40 C.F.R.
Part 000 Xxxxxxxx X; (ii) that any hazardous waste, as defined by 42
U.S.C. Section 6903(5), any hazardous substances as defined by 42
U.S.C. Section 9601(14), any pollutant or contaminant as defined by 42
U.S.C. Section 9601(33) or any toxic substance, oil or hazardous
materials or other chemicals or substances regulated by any
Environmental Laws, excluding household hazardous waste ("Hazardous
Substances"), which any one of them has generated, transported or
disposed of, has been found at any site at which a federal, state,
provincial, territorial or local agency or other third party has
conducted or has ordered that the Company or any of its Subsidiaries
conduct a remedial investigation, removal or other response action
pursuant to any Environmental Law; or (iii) that it is or shall be a
named party to any claim, action, cause of action, complaint, legal or
administrative proceeding arising out of any third party's incurrence
of costs, expenses, losses or damages of any kind whatsoever in
connection with the Release of Hazardous Substances.

(c) (i) No portion of the Real Property or other assets
of the Company and its Subsidiaries has been used for the handling,
processing, storage or disposal of Hazardous Substances except in
accordance with applicable Environmental Laws, except as would not
reasonably be expected to have a material adverse effect on the
business, assets or financial condition of the Company and its
Subsidiaries on a consolidated basis; and no underground tank or other
underground storage receptacle for Hazardous Substances is located on
such properties; (ii) in the course of any activities conducted by the
Company, its Subsidiaries, or operators

70
-64-

of the Real Property or other assets of the Company and its

used on such properties except in accordance with applicable
Environmental Laws, except for occurrences that would not have a
material adverse effect on the business, assets or financial condition
of the Company and its Subsidiaries on a consolidated basis; (iii)
there have been no unpermitted Releases or threatened Releases of
Hazardous Substances on, upon, into or from the Real Property or other
assets of the Company or its Subsidiaries, which Releases would have a
material adverse effect on the value of such properties; (iv) to the
best of the Company's and its Subsidiaries' knowledge, there have been
no Releases on, upon, from or into any real property in the vicinity of
the Real Property or other assets of the Company or its Subsidiaries
which, through soil or groundwater contamination, may have come to be
located on, and which would reasonably be expected to have a material
adverse effect on the value of, such properties; and (v) in addition,
any Hazardous Substances that have been generated on the Real Property
or other assets of the Company or its Subsidiaries have been
transported offsite only by carriers having an identification number
issued by the EPA, treated or disposed of only by treatment or disposal
facilities maintaining valid permits as required under applicable
Environmental Laws, which transporters and facilities have been and
are, to the best of the Company's and its Subsidiaries' knowledge,
operating in compliance with such permits and applicable Environmental
Laws.

(d) None of the Real Property or other assets of the
Company or its Subsidiaries or any of the stock (or assets) being
acquired with proceeds of Loans is or shall be subject to any
applicable environmental clean-up responsibility law or environmental
restrictive transfer law or regulation, by virtue of the transactions

the Borrowers or Sanifill in this Agreement or in any agreement, instrument,
document, certificate, statement or letter furnished to the Banks or the Bank
Agents by or on behalf of or at the request of the Borrowers and Sanifill in
connection with any of the transactions contemplated by the Loan Documents

71
-65-

fact or omits to state a material fact necessary in order to make the statements
contained therein not misleading in light of the circumstances in which they are
made.

SECTION 7.18. PERMITS AND GOVERNMENTAL AUTHORITY. All permits (other
than those the absence of which would not have a material adverse effect on the
business, operations or financial condition of the Company and its Subsidiaries
as a whole) required for the construction and operation of all landfills
currently owned or operated by the Company or any of its Subsidiaries have been
obtained and remain in full force and effect and are not subject to any appeals
or further proceedings or to any unsatisfied conditions that may allow material
modification or revocation. Neither the Company nor any of its Subsidiaries,
nor, to the knowledge of the Company and its Subsidiaries, the holder of such
permits is in violation of any such permits, except for any violation which
would not have a material adverse effect on the business, operations or
financial condition of the Company and its Subsidiaries as a whole.

SECTION 8. AFFIRMATIVE COVENANTS OF THE BORROWERS. Each of the Company,
and the Canadian Borrowers where applicable, agrees that, so long as any
Obligation or any Letter of Credit is outstanding or the Banks have any
obligation to make Loans, or the Canadian Banks have any further obligation with
respect to Bankers' Acceptances, or the Issuing Bank has any obligation to
issue, extend or renew any Letters of Credit hereunder, or the Banks have any
obligations to reimburse the Issuing Bank for drawings honored under any Letter
of Credit, it shall, and shall cause its Subsidiaries to, comply with the
following covenants:

addition, simultaneously therewith, the Company shall provide the
Banks with a written statement from such Accountants to the effect
that they have read a copy of this Agreement, and that, in making the
examination necessary to said certification, they have obtained no
knowledge of any Default or Event of Default, or, if such Accountants
shall have obtained knowledge of any then existing Default or Event of
Default they shall disclose in such statement any such Default or
Event of Default;

(b) as soon as practicable, but in any event not later
than 47 days after the end of each of the first three fiscal quarters
of each fiscal year of the Company, copies of the consolidated balance
sheet and statement of operations of the Company and its Subsidiaries
as at the end of such quarter, subject to year-end adjustments, and
the related consolidated statement of cash flows, all in reasonable
detail and prepared in accordance with GAAP (to the extent GAAP is
applicable to interim unaudited financial statements) with a
certification by the principal financial or accounting officer of the
Company (the "CFO or the CAO") that the consolidated financial
statements are prepared in accordance with GAAP (to the extent GAAP is
applicable to interim unaudited financial statements) and fairly
present the consolidated financial condition of the Company and its
Subsidiaries on a consolidated basis as at the close of business on
the date thereof and the results of operations for the period then
ended, it being understood that no such statement need be accompanied
by complete footnotes;

(c) simultaneously with the delivery of the financial
statements referred to in (a) and (b) above, a certificate in the form
of Exhibit I hereto (the "Compliance Certificate") signed by the CFO
or the CAO or the Company's corporate treasurer, stating that the
Company and its Subsidiaries are in compliance with the covenants
contained in Section Section 8, 9 and 10 hereof as of the end of the
applicable period and setting forth in
73
-67-

reasonable detail computations evidencing such compliance with respect
to the covenants contained in Section Section 9.1(e), 9.3, 9.4, 9.5,
and 10 hereof and that no Default or Event of Default exists, provided
that if the Company shall at the time of issuance of such Compliance
Certificate or at any other time obtain knowledge of any Default or
Event of Default, the Company shall include in such certificate or
otherwise deliver forthwith to the Banks a certificate specifying the
nature and period of existence thereof and what action the Company
proposes to take with respect thereto;

(d) contemporaneously with, or promptly following, the

(e) from time to time such other financial data and other
information as the Banks may reasonably request.

The Borrowers hereby authorize each Bank to disclose any information
obtained pursuant to this Agreement to all appropriate governmental regulatory
authorities where required by law; provided, however, this authorization shall
not be deemed to be a waiver of any rights to object to the disclosure by the
Banks of any such information which any Borrower has or may have under the
federal Right to Financial Privacy Act of 1978, as in effect from time to time,
except as to matters specifically permitted therein.

SECTION 8.5. CORPORATE EXISTENCE AND CONDUCT OF BUSINESS. The Company
will, and will cause each Subsidiary, to do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence,
corporate rights and franchises; and effect and maintain its foreign
qualifications (except where the failure of the Company or any Subsidiary to
remain so qualified would not materially adversely impair the financial
condition, business or assets of the Company and its Subsidiaries on a
consolidated basis), licensing, domestication or authorization except as
terminated by its Board of Directors in the exercise of its reasonable judgment;
provided that such termination would not have a material adverse effect on the
financial condition, business or assets of the Company and its Subsidiaries on a
consolidated basis. The Company will not, and will cause its Subsidiaries not
to, become obligated under any contract or binding arrangement which, at the
time it was entered into, would materially adversely impair the financial
condition, business or assets of the Company and its Subsidiaries, on a
consolidated basis. The Company will, and will cause each Subsidiary to,
continue to engage primarily in the businesses now conducted by it and in
related businesses.

SECTION 8.6. MAINTENANCE OF PROPERTIES. The Company will, and will
cause its Subsidiaries to, cause all material properties used or useful in the
conduct of
74
-68-

their businesses to be maintained and kept in good condition, repair and working
order (ordinary wear and tear excepted) and supplied with all necessary
equipment and cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company and
its Subsidiaries may be necessary so that the businesses carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this section shall prevent the Company or any
of its Subsidiaries from discontinuing the operation and maintenance of any of
its properties if such discontinuance is, in the judgment of the Company or such
Subsidiary, desirable in the conduct of its or their business and which does not
in the aggregate materially adversely affect the financial condition, business
or assets of the Company and its Subsidiaries on a consolidated basis.

SECTION 8.7. INSURANCE. The Company will, and will cause its
Subsidiaries to, maintain with financially sound and reputable insurance
companies, funds or underwriters, insurance of the kinds, covering the risks
(other than risks arising out of or in any way connected with personal liability
of any officers and directors thereof) and in the relative proportionate amounts
usually carried by reasonable and prudent companies conducting businesses
similar to that of the Company and its Subsidiaries, in amounts substantially
similar to the existing coverage policies maintained by the Company and its
Subsidiaries, copies of which have been provided to the Documentation Agent. In
addition, the Company will furnish from time to time, upon any Bank's request, a
summary of the insurance coverage of the Company and its Subsidiaries, which
summary shall be in form and substance satisfactory to the Banks and, if
requested by any of the Banks, will furnish to the Documentation Agent and such
Bank copies of the applicable policies.

SECTION 8.8. TAXES. The Company will, and will cause its Subsidiaries
to, duly pay and discharge, or cause to be paid and discharged, before the same
shall become overdue, all taxes, assessments and other governmental charges
(other than taxes, assessments and other governmental charges imposed by
jurisdictions other than the United States, Canada or any political subdivision
thereof, which in the aggregate are not material to the business, financial
conditions, or assets of the Company and its Subsidiaries on a consolidated
basis) imposed upon it and its real properties, sales and activities, or any
part thereof, or upon the income or profits therefrom, as well as all claims for
labor, materials, or supplies, which if unpaid might by law become a lien or
charge upon any of its property; provided, however, that any such tax,
assessment, charge, levy or claim need not be paid if the validity or amount
thereof shall currently be contested in good faith by appropriate proceedings
and if the Company or such Subsidiary shall have set aside on its books adequate
reserves with respect thereto as required by GAAP; and provided, further, that
the Company or such Subsidiary will pay all such taxes, assessments, charges,
75
-69-

levies or claims forthwith upon the commencement of proceedings to foreclose
any lien which may have attached as security therefor.

SECTION 8.9. INSPECTION OF PROPERTIES, BOOKS AND CONTRACTS. The Company
will, and will cause its Subsidiaries to, permit the Bank Agents or any Bank or
any of their designated representatives, upon reasonable notice, to visit and
inspect any of the properties of the Company and its Subsidiaries, to examine
the books of account of the Company and its Subsidiaries, or contracts (and to
make copies thereof and extracts therefrom), and to discuss the affairs,
finances and accounts of the Company and its Subsidiaries with, and to be
advised as to the same by, their officers, all at such times and intervals
as may be reasonably requested.

SECTION 8.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES AND PERMITS;
MAINTENANCE OF MATERIAL LICENSES AND PERMITS. The Company will, and will cause
each Subsidiary to, (i) comply with the provisions of its charter documents and
by-laws; (ii) comply in all material respects with all agreements and
instruments by which it or any of its properties may be bound; (iii) comply with
all applicable laws and regulations (including Environmental Laws), decrees,
orders, judgments, licenses and permits, including, without limitation, all
environmental permits ("Applicable Requirements"), except where noncompliance
with such Applicable Requirements would not reasonably be expected to have a
material adverse effect in the aggregate on the consolidated financial
condition, properties or businesses of the Company and its Subsidiaries; and
(iv) maintain all material operating permits for all landfills now owned or
hereafter acquired; and (v) dispose of hazardous waste only at licensed disposal
facilities operating, to the best of the Company's or such Subsidiary's
knowledge after reasonable inquiry, in compliance with Environmental Laws. If
at any time any authorization, consent, approval, permit or license from any
officer, agency or instrumentality of any government shall become necessary or
required in order that the Company or any Subsidiary may fulfill any of its
obligations hereunder or under any other Loan Document, the Company will
immediately take or cause to be taken all reasonable steps within the power of
the Company or such Subsidiary to obtain such authorization, consent, approval,
permit or license and furnish the Banks with evidence thereof.

SECTION 8.11. ENVIRONMENTAL INDEMNIFICATION. The Company covenants and
agrees that it will indemnify and hold the Banks, the Issuing Bank and the Bank
Agents and their respective affiliates, and each of the representatives, agents
and officers of each of the foregoing, harmless from and against any and all
claims, expense, damage, loss or liability incurred by the Banks, the Issuing
Bank or the Bank Agents (including all costs of legal representation incurred by
the Banks, the Issuing Banks or the Bank Agents) relating to (a) any Release or
threatened Release of Hazardous Substances on the Real Property; (b) any
76
-70-

violation of any Environmental Laws or Applicable Requirements with respect to
conditions at the Real Property or other assets of the Company or its
Subsidiaries, or the operations conducted thereon; or (c) the investigation or
remediation of offsite locations at which the Company, any of its Subsidiaries,
or their predecessors are alleged to have directly or indirectly Disposed of
Hazardous Substances. Further, each of the Canadian Borrowers covenants and
agrees that it will indemnify and hold the Canadian Banks and the Canadian Agent
and their respective affiliates, and each of the representatives, agents and
officers of each of the foregoing, harmless as and to the same extent as the
Company indemnifies the Banks, the Issuing Bank and Bank Agents above, provided,
that such indemnity by the Canadian Borrowers shall apply only to the extent
that matters set forth in clauses (a), (b) and (c) above relate to the Real
Property owned or operated by the Canadian Borrowers, or violations of
Environmental Laws or Disposal of Hazardous Wastes by the Canadian Borrowers.
It is expressly acknowledged by the Company and the Canadian Borrowers that this
covenant of indemnification shall survive the payment of the Loans, Bankers'
Acceptances and Reimbursement Obligations and satisfaction of all other
Obligations hereunder and shall inure to the benefit of the Banks, the Issuing
Bank, the Bank Agents and their affiliates, successors and assigns.

SECTION 8.12. FURTHER ASSURANCES. Each of the Borrowers and Sanifill
will cooperate with the Documentation Agent and execute such further instruments
and documents as the Documentation Agent shall reasonably request to carry out
to the Banks' satisfaction the transactions contemplated by this Agreement.

SECTION 8.13. NOTICE OF POTENTIAL CLAIMS OR LITIGATION. The Company
shall deliver to the Banks, within 30 days of receipt thereof, written notice of
the initiation of any action, claim, complaint, or any other notice of dispute

the potential liability is in excess of $10,000,000 together with a copy of each
such notice received by the Company or any of its Subsidiaries.

cancellation or material change by any of its insurers.

(b) The Company will promptly notify the Banks in writing

77

Hazardous Substances with respect to which the Company or any
Subsidiary may be liable or for which a lien may be imposed on
the Real Property.

SECTION 8.15. NOTICE OF DEFAULT. The Company will promptly notify the
Banks in writing of the occurrence of any Default or Event of Default. If any

or any other note, evidence of indebtedness, indenture or other obligation
evidencing indebtedness in excess of $10,000,000 as to which the Company or any
of its Subsidiaries is a party or obligor, whether as principal or surety, the

substantial interest or is an officer, director, trustee or partner.

Company, and the Canadian Borrowers where applicable, agrees that, so long as
any Obligation or Letter of Credit or Bankers' Acceptance is outstanding or the
Banks have any obligation to make Loans or the Canadian Banks have any further

this sentence shall only be in effect for so long as the Company

event reasonably could be expected to result in liability of the
Company or any Subsidiary to the PBGC or similar Canadian authorities
or the Plan in an aggregate amount exceeding $10,000,000 and such

Agents may, and upon the request of the Majority Banks shall, by notice in
writing to the Borrowers, declare all amounts owing with respect to this
Agreement, the Notes and the other Loan Documents and all Reimbursement
Obligations to be, and they shall thereupon forthwith become, immediately due
and payable without presentment, demand, protest, notice of intent to

notice of any kind, all of which are hereby expressly waived by the Borrowers;
provided that in the event of any Event of Default specified in Section 13.1(g)
or 13.1(h), all such amounts shall become immediately due and payable
automatically and without any requirement of notice from the Bank Agents or any

the Banks and the Issuing Banks shall be relieved of all obligations to make
Loans, to accept and purchase Bankers' Acceptances or to issue, extend or renew
Letters of Credit hereunder; or if any other Event of Default shall occur, the
Majority Banks may by notice to the Borrowers terminate the unused portion of

elsewhere.

SECTION 13.3. REMEDIES. In case any one or more of the Events of

shall have accelerated the maturity of the Loans and other Obligations pursuant

with respect to the Loans, Bankers' Acceptances or the Reimbursement
Obligations, may proceed to protect and enforce its rights by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement and the
other Loan Documents or any instrument pursuant to which the Obligations to
such Bank are evidenced, including, without limitation, as permitted by
applicable law the obtaining of the ex parte appointment of a receiver, and, if
such amount shall have become due, by declaration or otherwise, proceed to
enforce the payment thereof or any legal or equitable right of such Bank, any
recovery being subject to the terms of Section 30 hereof. No remedy herein
conferred upon any Bank or the Bank Agents or the holder of any Note is
intended to be exclusive of any other remedy and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or
now or hereafter existing at law or in equity or by statute or any other
provision of law.

during the continuance of an Event of Default, any deposits or other sums
credited by or due from any Bank to the Borrowers or any of them and any
securities or other property of the Borrowers or any of them in the possession
of such Bank may be applied to or set off against the payment of Obligations
and any and all other
92
-86-

liabilities, direct, or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of the Borrowers to the Banks or the Bank
Agents. Any amounts set off pursuant to this Section 14 shall be distributed
ratably in accordance with Section 30 among all of the Banks by the Bank
setting off such amounts. If any Bank fails to share such setoff ratably, the
Administrative Agent and/or the Canadian Agent, as applicable, shall have the
right to withhold such Bank's share of any Borrower's payments until each of
the Banks shall have, in the aggregate, received a pro rata repayment.

SECTION 15. EXPENSES. Whether or not the transactions contemplated
herein shall be consummated, the Borrowers hereby promise to reimburse the
Documentation Agent for all reasonable out-of-pocket fees and disbursements
(including all reasonable attorneys' fees) incurred or expended in connection
with the preparation, filing or recording, or interpretation of this Agreement,
the other Loan Documents, or any amendment, modification, approval, consent or
waiver hereof or thereof. The Borrowers further promise to reimburse the Bank
Agents and the Banks for all reasonable out-of-pocket fees and disbursements
(including all reasonable legal fees and the allocable cost of in-house
attorneys' fees) incurred or expended in connection with the enforcement of any
Obligations or the satisfaction of any indebtedness of the Borrowers hereunder
or under any other Loan Document, or in connection with any litigation,
proceeding or dispute hereunder in any way related to the credit hereunder. The
Company also promises to pay the Administrative Agent all reasonable
out-of-pocket fees and disbursements, incurred or expended in connection with

SECTION 16. THE BANK AGENTS.

SECTION 16.1. APPOINTMENT, POWERS AND IMMUNITIES. Each Bank hereby
irrevocably appoints and authorizes (a) MGT to act as Documentation Agent, (b)
MGT to act as Administrative Agent, and (c) MBC to act as Canadian Agent
hereunder and under the other Loan Documents, provided, however, the
Administrative Agent, Documentation Agent, and Canadian Agent are hereby
authorized to serve only as administrative and documentation agents, as
applicable, for the Banks and to exercise such powers as are reasonably
incidental thereto and as are set forth in this Agreement and the other Loan
Documents. The Bank Agents hereby acknowledge that they do not have the
authority to negotiate any agreement which would bind the Banks or agree to any
amendment, waiver or modification of any of the Loan Documents or bind the
Banks except as set forth in this Agreement or the Loan Documents. Except as
provided in this Agreement, and in the other Loan Documents, the Bank Agents
shall take action or refrain from acting only upon instructions of the Banks.
It is agreed that the duties, rights, privileges and immunities of the Issuing
Banks, in their capacity as issuers of Letters of Credit hereunder, shall be
identical to the duties, rights, privileges and immunities of the Bank Agents
93
-87-

as provided in this Section 16. The Bank Agents shall not have any duties or
responsibilities or any fiduciary relationship with any Bank except those
expressly set forth in this Agreement and the other Loan Documents. None of
the Bank Agents nor any of their affiliates shall be responsible to the Banks
for any recitals, statements, representations or warranties made by the
Borrowers or any other Person whether contained herein or otherwise or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement, the other Loan Documents or any other document referred to or
provided for herein or therein or for any failure by the Borrowers or any other
Person to perform its obligations hereunder or thereunder or in respect of the
Notes. The Bank Agents may employ agents and attorneys-in-fact and shall not
be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care. Neither the Bank Agents
nor any of their directors, officers, employees or agents shall be responsible
for any action taken or omitted to be taken by it or them hereunder or in
connection herewith, except for its or their own gross negligence or willful
misconduct. Any Bank Agent in its separate capacity as a Bank shall have the
same rights and powers hereunder as any other Bank.

SECTION 16.2. ACTIONS BY BANK AGENTS. Each Bank Agent shall be fully
justified in failing or refusing to take any action under this Agreement as
reasonably deemed appropriate unless it shall first have received the consent
of the Majority Banks (or, when expressly required hereby, all of the Banks),
and shall be indemnified to its reasonable satisfaction by the Banks against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action. The Bank Agents shall in all
cases be fully protected in acting, or in refraining from acting, under this
Agreement or any of the Loan Documents in accordance with the instruction of
the Majority Banks (or, when expressly required hereby or thereby, all of the
Banks), and such instruction and any action taken or failure to act pursuant
thereto shall be binding upon the Banks and all future holders of the Notes or
any Letter of Credit Participation.

SECTION 16.3. INDEMNIFICATION. Without limiting the obligations of the
Borrowers hereunder or under any other Loan Document, the Banks agree to
indemnify the Bank Agents, their affiliates and their respective directors,
officers, agents and employees (to the extent not reimbursed by the Borrowers)
ratably in accordance with their respective Domestic Commitment Percentages and
Canadian Commitment Percentages, as applicable, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may at any
time be imposed on, incurred by or asserted against the Bank Agents in any way
relating to or arising out of this Agreement or any other Loan Document or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or the enforcement of any of the
94
-88-

terms hereof or thereof or of any such other documents; provided, that no Bank
shall be liable for any of the foregoing to the extent they arise from the
gross negligence or willful misconduct of the applicable Bank Agents (or any
agent thereof), IT BEING THE INTENT OF THE PARTIES HERETO THAT ALL SUCH
INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR THEIR ORDINARY SOLE OR
CONTRIBUTORY NEGLIGENCE.

SECTION 16.4. REIMBURSEMENT. Without limiting the provisions of
Section Section 6.1(a), 6.13, and 14, no Bank Agent shall be obliged to make
available to any Person any sum which such Bank Agent is expecting to receive
for the account of that Person until such Bank Agent has determined that it has
received that sum. A Bank Agent may, however, disburse funds prior to
determining that the sums which such Bank Agent expects to receive have been
finally and unconditionally paid to such Bank Agent, if such Bank Agent wishes
to do so. If and to the extent that a Bank Agent does disburse funds and it
later becomes apparent that such Bank Agent did not then receive a payment in
an amount equal to the sum paid out, then any Person to whom such Bank Agent
made the funds available shall, on demand from such Bank Agent, refund to such
Bank Agent the sum paid to that Person. If, in the opinion of a Bank Agent,
the distribution of any amount received by it in such capacity hereunder or
under the other Loan Documents might involve it in liability, it may refrain
from making distribution until its right to make distribution shall have been
adjudicated by a court of competent jurisdiction. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by a Bank
Agent is to be repaid, each Person to whom any such distribution shall have
been made shall either repay to such Bank Agent its proportionate share of the
amount so adjudged to be repaid or shall pay over the same in such manner and
to such Persons as shall be determined by such court.

SECTION 16.5. DOCUMENTS. The Bank Agents will forward to each Bank,
promptly after receipt thereof, a copy of each notice or other document
furnished to the Bank Agents for such Bank hereunder; provided, however, that,
notwithstanding the foregoing, the Administrative Agent may furnish to the
Banks a monthly summary with respect to Letters of Credit issued hereunder in
lieu of copies of the related Letter of Credit Applications.

SECTION 16.6. NON-RELIANCE ON BANK AGENTS AND OTHER BANKS. Each Bank
represents that it has, independently and without reliance on the Bank Agents,
the Agents or any other Bank, and based on such documents and information as it
has deemed appropriate, made its own appraisal of the financial condition and
affairs of the Borrowers and Sanifill and the decision to enter into this
Agreement and the other Loan Documents and agrees that it will, independently
and without reliance upon the Bank Agents, the Agents or any other Bank, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own appraisals and decisions in taking or not taking
95
-89-

action under this Agreement or any other Loan Document. Except as herein
expressly provided to the contrary, the Bank Agents shall not be required to
keep informed as to the performance or observance by the Borrowers and Sanifill
of this Agreement, the other Loan Documents or any other document referred to
or provided for herein or therein or by any other Person of any other agreement
or to make inquiry of, or to inspect the properties or books of, any Person.
Except for notices, reports and other documents and information expressly
required to be furnished to the Banks by the Bank Agents hereunder, the Bank
Agents shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning any person which may come into the
possession of the Bank Agents or any of their affiliates. Each Bank shall have
access to all documents relating to the Bank Agents' performance of their
duties hereunder at such Bank's request. Unless any Bank shall promptly object
to any action taken by the Bank Agents hereunder of which such Bank has actual
knowledge (other than actions which require the prior consent of such Bank in
accordance with the terms hereof or to which the provisions of Section 16.8 are
applicable and other than actions which constitute gross negligence or willful
misconduct by the Bank Agents), such Bank shall be presumed to have approved
the same.

SECTION 16.7. RESIGNATION OF BANK AGENTS. A Bank Agent may resign at
any time by giving 60 days' prior written notice thereof to the Banks and the
applicable Borrower(s). Upon any such resignation, the Banks (other than the
resigning Bank Agent) shall have the right to appoint a successor Bank Agent
from among the Banks. If no successor to such Bank Agent shall have been so
appointed by the Banks and shall have accepted such appointment within 30 days
after the retiring Bank Agent's giving of notice of resignation, then the
retiring Bank Agent may, on behalf of the Banks, appoint a successor Bank Agent
from among the remaining Banks, which shall be a financial institution having a
combined capital and surplus in excess of $1,000,000,000. Upon the acceptance
of any appointment as Bank Agent hereunder by a successor Bank Agent, such
successor Bank Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Bank Agent, and the
retiring Bank Agent shall be discharged from its duties and obligations
hereunder. After any retiring Bank Agent's resignation, the provisions of this
Agreement 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 a Bank Agent. Any
new Issuing Bank appointed pursuant to this Section 16.7 shall immediately
issue new Letters of Credit in place of Letters of Credit previously issued or,
if acceptable to the resigning Issuing Bank, issue letters of credit in favor
of the resigning Issuing Bank as security for the outstanding Letters of Credit
and shall in due course replace all Letters of Credit previously issued by
the resigning Issuing Bank.

SECTION 16.8. ACTION BY THE BANKS, CONSENTS, AMENDMENTS, WAIVERS, ETC.
Any action to be taken (including the giving of notice) may be taken, any
consent or approval required or permitted by this Agreement or any other Loan
Document to be given by the Banks may be given, any term of this Agreement, any
other Loan Document or any other instrument, document or agreement related to
this Agreement or the other Loan Documents or mentioned therein may be amended,
and the performance or observance by the Borrowers or any other Person of any
of the terms thereof and any Default or Event of Default (as defined in any of
the above-referenced documents or instruments) may be waived (either generally
or in a particular instance and either retroactively or prospectively), only
with the written consent of the Majority Banks; provided, however, that no such
consent or amendment which affects the rights, duties or liabilities of any
Bank Agent or Issuing Bank shall be effective without the written consent of
such Bank Agent or Issuing Bank, as the case may be. Notwithstanding the
foregoing, no amendment, waiver or consent shall do any of the following unless
in writing and signed by ALL of the Banks (a) increase the principal amount of
the Total Commitment (or subject any Bank to any additional obligations), (b)
reduce the principal of or interest on the Notes (including, without
limitation, interest on overdue amounts) or any fees payable hereunder, (c)
postpone any date fixed for any payment in respect of principal or interest
(including, without limitation, interest on overdue amounts) on the Notes or
any fee hereunder; (d) change the definition of "Majority Banks" or number of
Banks which shall be required for the Banks or any of them to take any action
under the Loan Documents; (e) amend this Section 16.8; (f) change the Canadian

Section 2.3, (g) change the Domestic Commitment Percentage of any Domestic
Bank, except as permitted under Section 20 hereof and pursuant to Section 2.3,
(h) change the Total Commitment Percentage of any Bank, or (i) release any
Borrower or Guarantor from its obligations hereunder (except as expressly set
forth herein).

Section 17. INDEMNIFICATION. The Borrowers agree to indemnify and hold
harmless the Banks, the Agents, and the Bank Agents and their affiliates, as
well as the Banks' and the Bank Agents' and their affiliates' shareholders,
directors, agents, officers, subsidiaries and affiliates, from and against all
damages, losses, settlement payments, obligations, liabilities, claims, suits,
penalties, assessments, citations, directives, demands, judgments, actions or
causes of action, whether statutorily created or under the common law, and
reasonable costs and expenses incurred, suffered, sustained or required to be
paid by an indemnified party by reason of or resulting from the transactions
contemplated hereby, except any of the foregoing which result from the gross
negligence or willful misconduct of any indemnified party. In any
investigation, enforcement matter, proceeding or litigation, or the preparation
therefor, the Banks and the Bank Agents shall be entitled to select their own
counsel and, in addition to the foregoing indemnity, the Borrowers agree to pay
promptly the
97
-91-

reasonable fees and expenses of such counsel. In the event of the commencement
of any such proceeding or litigation against the Banks or Bank Agents by third
parties, the Borrowers shall be entitled to participate in such proceeding or
litigation with counsel of their choice at their expense, provided that such
counsel shall be reasonably satisfactory to the Banks or Bank Agents. The
covenants of this Section 17 shall survive payment or satisfaction of payment
of amounts owing with respect to any Note or any other Loan Document and
satisfaction of all the Obligations hereunder, IT BEING THE INTENT OF THE
PARTIES HERETO THAT ALL SUCH INDEMNIFIED PARTIES SHALL BE INDEMNIFIED FOR
THEIR ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE.

SECTION 18. WITHHOLDING TAXES. The Borrowers hereby agree that:

(a) Any and all payments made by any of the Borrowers
hereunder shall be made free and clear of, and without deduction for,
any and all present or future taxes, levies, fees, duties, imposts,
deductions, charges or withholdings of any nature whatsoever,
excluding, in the case of the Bank Agents or the Banks or any holder
of the Notes, (i) taxes imposed on, or measured by, its net income or
profits, (ii) franchise taxes imposed on it, (iii) taxes imposed by
any jurisdiction as a direct consequence of it, or any of its
affiliates, having a present or former connection with such
jurisdiction, including, without limitation, being organized, existing
or qualified to do business, doing business or maintaining a permanent
establishment or office in such jurisdiction, and (iv) taxes imposed
by reason of its failure to comply with any applicable certification,
identification, information, documentation or other reporting
requirement (all such non-excluded taxes being hereinafter referred to
as "Indemnifiable Taxes"). In the event that any withholding or
deduction from any payment to be made by the Borrowers hereunder is
required in respect of any Indemnifiable Taxes pursuant to any
applicable law, or governmental rule or regulation, then the Borrowers
will (i) direct to the relevant taxing authority the full amount
required to be so withheld or deducted, (ii) forward to the applicable
Bank Agent for delivery to the applicable Bank an official receipt or
other documentation satisfactory to the applicable Bank Agent and the
applicable Bank evidencing such payment to such taxing authority, and
(iii) direct to the applicable Bank Agent for the account of the
relevant Banks such additional amount or amounts as is necessary to
ensure that the net amount actually received by each relevant Bank
will equal the full amount such Bank would have received had no such
withholding or deduction (including any Indemnifiable Taxes on such
additional amounts) been required. Moreover, if any Indemnifiable
Taxes are directly asserted against the applicable Bank Agent or any
Bank with respect to any payment received by the Bank Agents or such
Bank by reason of the Borrowers' failure to
98
-92-

properly deduct and withhold such Indemnifiable Taxes from such
payment, the applicable Bank Agent or such Bank may pay such
Indemnifiable Taxes and the Borrowers will promptly pay all such
additional amounts (including any penalties, interest or reasonable
expenses) as is necessary in order that the net amount received by
such Person after the payment of such Indemnifiable Taxes (including
any Indemnifiable Taxes on such additional amount) shall equal the
amount such Person would have received had not such Indemnifiable
Taxes been asserted. Any such payment shall be made promptly after
the receipt by the Borrowers from the applicable Bank Agent or such
Bank, as the case may be, of a written statement setting forth in
reasonable detail the amount of the Indemnifiable Taxes and the
basis of the claim.

(b) The Borrowers shall pay any present or future stamp
or documentary taxes or any other excise or any other similar levies
which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document ("Other Taxes").

(c) The Borrowers hereby indemnify and hold harmless the
Bank Agents and each Bank for the full amount of Indemnifiable Taxes
or Other Taxes (including, without limitation, any Indemnifiable Taxes
or Other Taxes imposed on amounts payable under this Section 18) paid
by the Bank Agents or such Bank, as the case may be, and any liability
(including penalties, interest and reasonable expenses) arising
therefrom or with respect thereto, by reason of the Borrowers' failure
to properly deduct and withhold Indemnifiable Taxes pursuant to
paragraph (a) above or to properly pay Other Taxes pursuant to
paragraph (b) above. Any indemnification payment from the Borrowers
under the preceding sentence shall be made promptly after receipt by
the Borrowers from the applicable Bank Agent or Bank of a written
statement setting forth in reasonable detail the amount of such
Indemnifiable Taxes or such Other Taxes, as the case may be, and the
basis of the claim.

(d) If the Borrowers pay any amount under this Section 18
to the Bank Agents or any Bank and such payee knowingly receives a
refund of any taxes with respect to which such amount was paid, the
Bank Agents or such Bank, as the case may be, shall pay to the
Borrowers the amount of such refund promptly following the receipt
thereof by such payee.

(e) In the event any taxing authority notifies any of the
Borrowers that any of them has improperly failed to deduct or withhold
any taxes (other than Indemnifiable Taxes) from a payment made
hereunder to the Bank Agents or any Bank, the Borrowers shall timely
and fully pay such taxes to such taxing authority.
99
-93-

(f) The Bank Agents or the Banks shall, upon the request
of the Borrowers, take reasonable measures to avoid or mitigate the
amount of Indemnifiable Taxes required to be deducted or withheld from
any payment made hereunder if such measures can be taken without such
Person in its sole judgment suffering any legal, regulatory or
economic disadvantage.

(g) Without prejudice to the survival of any other
agreement of the parties hereunder, the agreements and obligations of
the Borrowers contained in this Section 18 shall survive the payment
in full of the Obligations.

SECTION 19. SURVIVAL OF COVENANTS, ETC. Unless otherwise stated
herein, all covenants, agreements, representations and warranties made herein,
in the other Loan Documents or in any documents or other papers delivered by or
on behalf of the Borrowers and Sanifill pursuant hereto shall be deemed to have
been relied upon by the Banks, the Issuing Banks and the Bank Agents,
notwithstanding any investigation heretofore or hereafter made by them, and
shall survive the making by the Banks of the Loans, the accepting and
purchasing of Bankers' Acceptances and the issuance, extension or renewal of
any Letters of Credit by any Issuing Bank, as herein contemplated, and shall
continue in full force and effect so long as any amount due under this
Agreement, any Obligation, any Letter of Credit, any Bankers' Acceptance or any
Note remains outstanding and unpaid or any Bank has any obligation to make any
Loans or any Issuing Bank has any obligation to issue, extend, or renew any
Letters of Credit hereunder or any Canadian Bank has any obligation to accept
or purchase any Bankers' Acceptances. All statements contained in any
certificate or other paper delivered by or on behalf of the Borrowers pursuant
hereto or in connection with the transactions contemplated hereby shall
constitute representations and warranties by the Borrowers hereunder.

SECTION 20. ASSIGNMENT AND PARTICIPATION. It is understood and agreed
that each Bank shall have the right to assign at any time all or a portion of
its Domestic Commitment Percentage and Canadian Commitment Percentage, as
applicable, and interests in the risk relating to the Loans, outstanding
Letters of Credit, Bankers' Acceptances and its Domestic Commitment and
Canadian Commitment, as applicable, hereunder in an amount equal to or greater
than $5,000,000 (which assignment shall be of an equal percentage of (a) the
Domestic Commitment, the Domestic Loans and outstanding Domestic Letters of
Credit, or (b) the Canadian Commitment, the Canadian Loans, the Bankers'
Acceptances, and the outstanding Canadian Letters of Credit, unless in each
case otherwise agreed to by the Bank Agents) to additional banks or other
financial institutions with the prior written approval of the Administrative
Agent or the Canadian Agent, as applicable, the Documentation Agent and, so
long as no Event of Default has occurred and is continuing, the applicable
Borrower(s), which approvals shall not be
100
-94-

unreasonably withheld; provided that a Bank may assign all or a portion of its
Canadian Commitment Percentage and Canadian Loans outstanding, Canadian Letters
of Credit and Bankers' Acceptances, only to an Eligible Canadian Assignee. Any
Bank may at any time, and from time to time, assign to any branch, lending
office, or affiliate or such Bank all or any part of its rights and obligations
under the Loan Documents by notice to the Agents and the Company. It is
further agreed that each bank or other financial institution which executes and
delivers to the Documentation Agent and the Borrowers hereunder an Assignment
and Acceptance substantially in the form of Exhibit J hereto (an "Assignment
and Acceptance") together with an assignment fee in the amount of $2,500
payable by the assigning Bank to the Documentation Agent, shall, on the date
specified in such Assignment and Acceptance, become a party to this Agreement
and the other Loan Documents for all purposes of this Agreement and the other
Loan Documents, and its portion of the Domestic Commitment and Canadian
Commitment, as applicable, the Loans and Letters of Credit and Bankers'
Acceptances shall be as set forth in such Assignment and Acceptance. The Bank
assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights and be released from its obligations under this Agreement and the
other Loan Documents. Upon the execution and delivery of such Assignment and
Acceptance, (a) the Borrowers shall issue to the assignee bank or other
financial institution Notes in the amount of such bank's or other financial
institution's Domestic Commitment or Canadian Commitment, dated the date of the
assignment or such other date as may be specified by the Documentation Agent,
and otherwise completed in substantially the form of Exhibits A, B or C, and to
the extent any assigning Bank has retained a portion of its obligations
hereunder, a replacement Syndicated Note and Canadian Note, as applicable, to
the assigning Bank reflecting its assignment; (b) to the extent applicable, the
Company shall issue a Competitive Bid Note in substantially the form of Exhibit
D (and a replacement Competitive Bid Note) or the Administrative Agent shall
make appropriate entries on the Competitive Bid Loan Accounts to reflect such
assignment of Competitive Bid Loan(s); (c) the Documentation Agent shall
distribute to the Borrowers, the Banks and such bank or financial institution a
schedule reflecting such changes; and (d) this Agreement shall be deemed to be
appropriately amended to reflect (i) the status of the bank or financial
institution as a party hereto and (ii) the status and rights of the Banks
hereunder.

Each Bank shall also have the right to grant participations to one or
more banks or other financial institutions in its Domestic Commitment or
Canadian Commitment, the Loans, Bankers' Acceptances and outstanding Letters of
Credit. The documents evidencing any such participation shall limit such
participating bank's or financial institution's voting rights with respect to
this Agreement to the matters set forth in Section 16.8 which require the
approval of all Banks.
101
-95-

Notwithstanding the foregoing, no assignment or participation shall
operate to increase the Total Commitment hereunder or otherwise alter the
substantive terms of this Agreement, and no Bank which retains a Commitment
hereunder shall have a Commitment of less than $10,000,000, as such amount may
be reduced upon reductions in the Total Commitment pursuant to Section 2.3
hereof.

Anything contained in this Section 20 to the contrary notwithstanding,
any Bank may at any time pledge all or any portion of its interest and rights
under this Agreement (including all or any portion of its Notes) to any of the
twelve Federal Reserve Banks organized under Section 4 of the Federal Reserve
Act, 12 U.S.C. Section 341. No such pledge or the enforcement thereof shall
release the pledgor Bank from its obligations hereunder or under any of the
other Loan Documents.

SECTION 21. PARTIES IN INTEREST. All the terms of this Agreement and
the other Loan Documents shall be binding upon and inure to the benefit of and
be enforceable by the respective successors and assigns of the parties hereto
and thereto; provided, that the Borrowers shall not assign or transfer their
rights or obligations hereunder or thereunder without the prior written
consent of each of the Banks.

SECTION 22. NOTICES, ETC. Except as otherwise expressly provided in
this Agreement, all notices and other communications made or required to be

Agreement are for convenience of reference only and shall not define or limit

which when so executed and delivered shall be an original, but all of which
together shall constitute one instrument. In proving this Agreement it shall
not be necessary to produce or account for more than one such counterpart
signed by the party against whom enforcement is sought.

SECTION 24. CONSENTS, ETC. Neither this Agreement nor any term hereof
may be changed, waived, discharged or terminated, except as provided in this
Section 24, subject to the provisions of Section 16.8. No waiver shall extend
to or affect any obligation not expressly waived or impair any right consequent

continuance of any Default or Event of Default may be waived (either generally
or in a particular instance and either retroactively or prospectively) with,

the extent permitted by law, no course of dealing or delay or omission on the
part of any of the Banks, the Issuing Banks or the Bank Agents in exercising
any right shall operate as a waiver thereof or otherwise be prejudicial
thereto. No notice to or demand upon the Borrowers shall entitle the Borrowers
to other or further notice or demand in similar or other circumstances.

SECTION 25. WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY
APPLICABLE LAW,EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL
RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY
DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN
DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE

WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS
AND (B) ACKNOWLEDGES THAT THE BANK AGENTS, THE BANKS, AND THE ISSUING BANKS
HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS

104
-98-

Section 28. JOINT AND SEVERAL LIABILITY; LIMITATION OF LIABILITY.
Notwithstanding anything herein to the contrary, each of the Canadian
Borrowers covenants and agrees that all Obligations with respect to all
Canadian Loans, Reimbursement Obligations with respect to Canadian Letters of
Credit, Bankers' Acceptances and any other Obligations payable to the Canadian
Agent or any of the Canadian Banks shall constitute the joint and several
obligation of such Canadian Borrower, and the Canadian Borrowers shall have no
liability for any such Obligations with respect to Syndicated Loans, Swing Line
Loans, Competitive Bid Loans and Reimbursement Obligations with respect to
Domestic Letters of Credit and any other Obligations payable to the
Administrative Agent or any of the Domestic Banks. Each of the Canadian
Borrowers, to the fullest extent permitted by applicable law, is accepting
joint and several liability for the Obligations of the Canadian Borrowers
hereunder and under the other Loan Documents in consideration of the financial
accommodation to be provided by the Canadian Agent and the Canadian Banks under
this Agreement, for the mutual benefit, directly or indirectly, of each of the
Canadian Borrowers and in consideration of the undertakings of each other
Canadian Borrower to accept the joint and several liability for the Obligations
of the Canadian Borrowers, and hereby waives any and all defenses with respect
thereto to the same degree and with the same force as the waiver by the
Guarantors set forth in Section 29.4 below and all rights with respect to
Article 15 Title 1 of General Obligations Law.

SECTION 29. GUARANTY.

SECTION 29.1. GUARANTY. For value received and hereby acknowledged
and as an inducement to the Banks and the Issuing Banks to make the Loans and
Letters of Credit available to the Borrowers and to accept and purchase
Bankers' Acceptances, Sanifill hereby unconditionally and irrevocably
guarantees (a) the full punctual payment when due, whether at stated maturity,
by acceleration or otherwise, of all Obligations of the Borrowers now or
hereafter existing whether for principal, interest, fees, expenses or
otherwise, and (b) the strict performance and observance by the Borrowers of
all agreements, warranties and covenants applicable to the Borrowers in the
Loan Documents and (c) the obligations of the Borrowers under the Loan
Documents (such Obligations collectively being hereafter referred to as
Sanifill's "Guaranteed Obligations"); and the Company hereby unconditionally
and irrevocably guarantees (a) the full punctual payment when due, whether at
stated maturity, by acceleration or otherwise, of all Obligations of the
Canadian Borrowers now or hereafter existing whether for principal, interest,
fees, expenses or otherwise, and (b) the strict performance and observance by
the Canadian Borrowers of all agreements, warranties and covenants applicable
to the Canadian Borrowers in the Loan Documents (such Obligations collectively
being hereinafter referred to as the Company's "Guaranteed Obligations").

105
-99-

SECTION 29.2. GUARANTY ABSOLUTE. Each of the Guarantors guarantees
that its Guaranteed Obligations will be paid strictly in accordance with the
terms hereof, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of any
Bank, any Issuing Bank or any Bank Agent with respect thereto. The liability
of the Guarantors under the guaranty granted under this Agreement with regard
to the Guaranteed Obligations shall be absolute and unconditional irrespective
of:

(a) any change in the time, manner or place of payment
of, or in any other term of, all or any of its Guaranteed Obligations
or any other amendment or waiver of or any consent to departure from
this Agreement or any other Loan Document (with regard to such
Guaranteed Obligations);

(b) any release or amendment or waiver of or consent to
departure from any other guaranty for all or any of its Guaranteed
Obligations;

(d) any acceptance of any partial payment(s) from the
Borrowers or the other Guarantor; or

(e) any other circumstance which might otherwise
constitute a defense available to, or a discharge of, any of the
Borrowers in respect of its Obligations under any Loan Document.

The guaranty under this Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any Guaranteed
Obligation is rescinded or must otherwise be returned by the Banks, the Issuing
Banks or the Bank Agents upon the insolvency, bankruptcy or reorganization of
any Borrower or otherwise, all as though such payment had not been made.

SECTION 29.3. EFFECTIVENESS; ENFORCEMENT. The guaranty under this
Agreement shall be effective and shall be deemed to be made with respect to
each Loan made, each Letter of Credit issued and each Bankers' Acceptance
accepted as of the time it is made, issued or accepted, as applicable. No
invalidity, irregularity or unenforceability by reason of any bankruptcy or
similar law, or any law or order of any government or agency thereof purporting
to reduce, amend or otherwise affect any liability of any Borrower, and no
defect in or insufficiency or want of powers of any Borrower or irregular or
improperly recorded exercise thereof, shall impair, affect, be a defense to or
claim against such guaranty. The guaranty under this Agreement is a continuing
guaranty and shall (a) survive any termination of this Agreement, and (b)
remain in full force and effect until payment in full of, and performance of,
all Guaranteed Obligations and all other amounts payable under the
guaranty under this

106
-100-

Agreement. Notwithstanding anything set forth in this Section 29 to the
contrary, Sanifill shall be released from its guaranty obligations upon the
satisfaction (as determined in the Bank Agents' judgment and evidenced by a
release executed by the Bank Agents) of the Prudential Private Placement Debt
and the Sanifill Convertible Subordinated Debt. The guaranty under this
Agreement is made for the benefit of the Bank Agents, the Issuing Banks and the
Banks and their successors and assigns, and may be enforced from time to time as
often as occasion therefor may arise and without requirement on the part of the
Bank Agents, the Issuing Banks or the Banks first to exercise any rights against
the Borrowers, or to resort to any other source or means of obtaining payment of
any of the said obligations or to elect any other remedy.

SECTION 29.4. WAIVER. Except as otherwise specifically provided in any
of the Loan Documents, each of the Guarantors hereby waives promptness,
diligence, protest, notice of protest, all suretyship defenses, notice of
acceptance and any other notice with respect to any of its Guaranteed
Obligations and the guaranty under this Agreement and any requirement that the
Banks, the Issuing Banks or the Bank Agents protect, secure, perfect any
security interest or lien or any property subject thereto or exhaust any right
or take any action against the Borrowers or any other Person. Each of the
Guarantors also irrevocably waives, to the fullest extent permitted by law, all
defenses which at any time may be available to it in respect of its Guaranteed
Obligations by virtue of any statute of limitations, valuation, stay,
moratorium law or other similar law now or hereafter in effect.

SECTION 29.5. EXPENSES. Each of the Guarantors hereby promises to
reimburse (a) the Documentation Agent for all reasonable out-of-pocket fees and
disbursements (including all reasonable attorneys' fees), incurred or expended
in connection with the preparation, filing or recording, or interpretation of
the guaranty under this Agreement, the other Loan Documents to which such
Guarantor is a party, or any amendment, modification, approval, consent or
waiver hereof or thereof, and (b) the Bank Agents, the Issuing Banks and the
Banks and their respective affiliates for all reasonable out-of-pocket fees and
disbursements (including reasonable attorneys' fees), incurred or expended in
connection with the enforcement of its Guaranteed Obligations (whether or not
legal proceedings are instituted). The Guarantors will pay any taxes
(including any interest and penalties in respect thereof) other than the Banks'
taxes based on overall income or profits, payable on or with respect to the
transactions contemplated by the guaranty under this Agreement, each of the
Guarantors hereby agreeing jointly and severally to indemnify each Bank
with respect thereto.

107
-101-

SECTION 29.6. CONCERNING JOINT AND SEVERAL LIABILITY OF THE GUARANTORS.

(a) Each of the Guarantors hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a
co-debtor, joint and several liability with the applicable
Borrower(s), with respect to the payment and performance of all of its
Guaranteed Obligations (including, without limitation, any Guaranteed
Obligations arising under this Section 29), it being the intention of
the parties hereto that all such Guaranteed Obligations shall be the
joint and several Guaranteed Obligations of such Guarantor and the
applicable Borrower(s) without preferences or distinction among them.

(b) If and to the extent that the applicable Borrower(s)
shall fail to make any payment with respect to any of its Guaranteed
Obligations as and when due or to perform any of its Guaranteed
Obligations in accordance with the terms thereof, then in each such
event the applicable Guarantor will make such payment with respect to,
or perform, such Guaranteed Obligation.

(c) The Guaranteed Obligations of each Guarantor under
the provisions of this Section 29 constitute full recourse obligations
of such Guarantor enforceable against such Guarantor to the full
extent of its properties and assets, irrespective of the validity,
regularity or enforceability of this Agreement or any other
circumstance whatsoever.

(d) Except as otherwise expressly provided in this
Agreement, each of the Guarantors hereby waives notice of acceptance
of its joint and several liability, notice of any Loans made, Bankers'
Acceptances accepted or Letters of Credit issued under this Agreement,
notice of any action at any time taken or omitted by the Bank Agents,
the Issuing Banks or the Banks under or in respect of any of the
Guaranteed Obligations, and, generally, to the extent permitted by
applicable law, all demands, notices and other formalities of every
kind in connection with this Agreement. Each of the Guarantors hereby
assents to, and waives notice of, any extension or postponement of the
time for the payment of any of the Guaranteed Obligations, the
acceptance of any payment of any of the Guaranteed Obligations, the
acceptance of any partial payment thereon, any waiver, consent or
other action or acquiescence by the Bank Agents, the Issuing Banks or
the Banks at any time or times in respect of any Default or Event of
Default by any of the Borrowers or the Guarantors in the performance
or satisfaction of any term, covenant, condition or provision of this
Agreement or any other Loan Document, any and all other indulgences
whatsoever by the Bank Agents, the Issuing Banks or the Banks in
respect of any of the Guaranteed Obligations, and the taking,
addition, substitution or release, in whole or in part, at any time

108
-102-

or times, of any security for any of the Guaranteed Obligations or the
addition, substitution or release, in whole or in part, of any of the
Borrowers or any other Guarantor. Without limiting the generality of
the foregoing, each of the Guarantors assents to any other action or
delay in acting or failure to act on the part of the Banks, the
Issuing Banks or the Bank Agents with respect to the failure by any of
the Borrowers or the other Guarantor to comply with its respective
Obligations or Guaranteed Obligations, including, without limitation,
any failure strictly or diligently to assert any right or to pursue
any remedy or to comply fully with applicable laws or regulations
thereunder, which might, but for the provisions of this Section 29,
afford grounds for terminating, discharging or relieving the
Guarantors, in whole or in part, from any of the Guaranteed
Obligations under this Section 29, it being the intention of the
Guarantors that, so long as any of the Guaranteed Obligations
hereunder remain unsatisfied, the Guaranteed Obligations of each of
the Guarantors under this Section 29 shall not be discharged except by
performance and then only to the extent of such performance. The
Guaranteed Obligations of each of the Guarantors under this Section 29
shall not be diminished or rendered unenforceable by any winding up,
reorganization, arrangement, liquidation, reconstruction or similar
proceeding with respect to any of the Borrowers or the Guarantors or
the Banks, the Issuing Banks or the Bank Agents. The joint and
several liability of each of the Guarantors hereunder shall continue
in full force and effect notwithstanding any absorption, merger,
consolidation, amalgamation or any other change whatsoever in the
name, membership, constitution or place of formation of the Borrowers
or the Guarantors, the Banks, the Issuing Banks or the Bank Agents.

(e) Sanifill, and, solely in its capacity as a Guarantor
of the Obligations of the Canadian Borrowers under this Section 29,
the Company, shall be liable under the Guaranty under this Section 29
only for the maximum amount of such liabilities that can be incurred
under applicable law without rendering this Agreement, as it relates
to the guaranty under this Section 29, voidable under applicable law
relating to fraudulent conveyance and fraudulent transfer, and not for
any greater amount. Accordingly, if any obligation under any
provision of the guaranty under this Section 29 shall be declared to
be invalid or unenforceable in any respect or to any extent, it is the
stated intention and agreement of the Guarantors, the Bank Agents, the
Issuing Banks and the Banks that any balance of the obligation created
by such provision and all other obligations of the Guarantors under
this Section 29 to the Banks, the Issuing Banks or the Bank Agents
shall remain valid and enforceable, and that all sums not in excess of
those permitted under applicable law shall remain fully collectible by
the Banks, the Issuing Banks and the Bank Agents from Sanifill or the
Company, as the case may be.

109
-103-

(f) The provisions of this Section 29 are made for the
benefit of the Bank Agents, the Issuing Banks and the Banks and their
successors and assigns, and may be enforced in good faith by them from
time to time against the Guarantors as often as occasion therefor may
arise and without requirement on the part of the Bank Agents, the
Issuing Banks or the Banks first to marshal any of their claims or to
exercise any of their rights against the Borrowers or the Guarantors
or to exhaust any remedies available to them against the Borrowers or
the Guarantors or to resort to any other source or means of obtaining
payment of any of the obligations hereunder or to elect any other
remedy. The provisions of this Section 29 shall remain in effect
until all of the Guaranteed Obligations shall have been paid in full
or otherwise fully satisfied and the Domestic Commitments and Canadian
Commitments have expired and all outstanding Letters of Credit and
Bankers' Acceptances have expired, matured or otherwise been
terminated. If at any time, any payment, or any part thereof, made in
respect of any of the Guaranteed Obligations, is rescinded or must
otherwise be restored or returned by the Banks, the Issuing Banks or
the Bank Agents upon the insolvency, bankruptcy or reorganization of
any of the Borrowers or the Guarantors, or otherwise, the provisions
of this Section 29 will forthwith be reinstated in effect, as though
such payment had not been made.

SECTION 29.7. WAIVER. Until the final payment and performance in full
of all of the Obligations, neither of the Guarantors shall exercise and each
of the Guarantors hereby waives any rights such Guarantor may have against the
Borrowers or the other Guarantor arising as a result of payment by such
Guarantor hereunder, by way of subrogation, reimbursement, restitution,
contribution or otherwise, and will not prove any claim in competition with the
Bank Agents, the Issuing Banks or any Bank in respect of any payment hereunder
in any bankruptcy, insolvency or reorganization case or proceedings of any
nature; such Guarantor will not claim any setoff, recoupment or counterclaim
against the Borrowers or the other Guarantor in respect of any liability of the
Borrowers to such Guarantor; and such Guarantor waives any benefit of and any
right to participate in any collateral security which may be held by the Bank
Agents, the Issuing Banks or any Bank.

SECTION 29.8. SUBROGATION; SUBORDINATION. The payment of any amounts
due with respect to any indebtedness of the Borrowers for money borrowed or
credit received now or hereafter owed to either of the Guarantors is hereby
subordinated to the prior payment in full of all of the Obligations. Each of
the Guarantors agrees that, after the occurrence of any default in the payment
or performance of any of the Obligations, such Guarantor will not demand, xxx
for or otherwise attempt to collect any such indebtedness of the Borrowers or
the other Guarantor to such Guarantor until all of the Obligations shall have
been paid in full. If, notwithstanding the foregoing sentence, either of the

110
-104-

Guarantors shall collect, enforce or receive any amounts in respect of such
indebtedness while any Obligations are still outstanding, such amounts shall be
collected, enforced and received by such Guarantor as trustee for the Banks,
the Issuing Banks and the Bank Agents and be paid over to the Administrative
Agent at Default, for the benefit of the Banks, the Issuing Banks, and the Bank
Agents on account of the Obligations without affecting in any manner the
liability of such Guarantor under the other provisions hereof.

SECTION 29.9. CURRENCY OF PAYMENT. Each of the Guarantors shall pay
its respective Guaranteed Obligations in the currency in which such Obligation
was incurred by the applicable Borrower(s).

SECTION 30. PARI PASSU TREATMENT.

(a) Notwithstanding anything to the contrary set forth
herein, each payment or prepayment of principal and interest received
after the occurrence of an Event of Default hereunder shall be
distributed pari passu among the Banks, in accordance with the
aggregate outstanding principal amount of the Obligations owing to
each Bank divided by the aggregate outstanding principal amount of all
Obligations..

(b) Following the occurrence and during the continuance
of any Event of Default, each Bank agrees that if it shall, through
the exercise of a right of banker's lien, setoff or counterclaim
against any Borrower (pursuant to Section 14 or otherwise), including
a secured claim under Section 506 of the Bankruptcy Code or other
security or interest arising from or in lieu of, such secured claim,
received by such Bank under any applicable bankruptcy, insolvency or
other similar law or otherwise, obtain payment (voluntary or
involuntary) in respect of the Notes, Loans, Bankers' Acceptances,
Reimbursement Obligations and other Obligations held by it (other than
pursuant to Section 6.5, Section 6.6 or Section 6.8) as a result of
which the unpaid principal portion of the Notes and the Obligations
held by it shall be proportionately less than the unpaid principal
portion of the Notes and Obligations held by any other Bank, it shall
be deemed to have simultaneously purchased from such other Bank a
participation in the Notes and Obligations held by such other Bank, so
that the aggregate unpaid principal amount of the Notes, Obligations
and participations in Notes and Obligations held by each Bank shall be
in the same proportion to the aggregate unpaid principal amount of the
Notes and Obligations then outstanding as the principal amount of the
Notes and other Obligations held by it prior to such exercise of
banker's lien, setoff or counterclaim was to the principal amount of
all Notes and other Obligations outstanding prior to such exercise of
banker's lien, setoff or counterclaim; provided, however, that if any
such purchase or purchases or adjustments shall be made pursuant to
this Section 30 and the payment
111
-105-

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 adjustments restored
without interest. Each Borrower expressly consents to the foregoing
arrangements and agrees that any Person holding such a participation
in the Notes and the Obligations deemed to have been so purchased may
exercise any and all rights of banker's lien, setoff or counterclaim
with respect to any and all moneys owing by such Borrower to such
Person as fully as if such Person had made a Loan directly to such
Borrower in the amount of such participation.

SECTION 31. FINAL AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.
