         (14)     Type of Reporting Person

                  BK

         Item 1.  Security and Issuer.

         This statement relates to the common stock, par value $.001 per share
(the "IC Common Stock"), of Illinois Central Corporation, a Delaware corporation
("IC"). The principal executive offices of IC are located at 455 North Cityfront
Plaza, Chicago, Illinois 60611-5504.

         Item 2.  Identity and Background.

         This statement is filed by Blackhawk Merger Sub, Inc. ("Merger Sub"),
Grand Trunk Corporation ("GTC"), Canadian National Railway Company ("CN") and
The Bank of New York (the "Trustee"; CN, GTC, Merger Sub and the Trustee,
collectively, the "Reporting Persons"). Merger Sub is a wholly-owned subsidiary
of GTC and GTC is a wholly-owned subsidiary of CN. Merger Sub and GTC are
organized under the laws of Delaware. CN is organized under the laws of Canada.
The Trustee is organized under the laws of New York. The address of the
principal business and principal office of Merger Sub, GTC and CN is 935 de La
Gauchetiere Street West, Montreal, Quebec, Canada H3B 2M9. The address of the
principal corporate trust office of the Trustee is 101 Barclay Street, New York,
New York 10286.

         CN operates the larger of Canada's two principal railroads and is the
sixth largest railroad in North America based on its 1997 annual revenues. GTC
is a holding company for CN's operations in the United States. Merger Sub was
incorporated on February 3, 1998 and to date has engaged in no activities other
than those undertaken in connection with the Offer (as defined in Item 4) and
the Merger (as defined in Item 4). The Trustee's principal business is the
provision of commercial banking, custody, trust and other financial services.
Pursuant to Rule 13d-4 (17 CFR 240.13d-4) under the Exchange Act, the Trustee
hereby declares that the filing of this statement shall not be construed as an
admission that the Trustee is for purposes of Sections 13(d) or 13(g) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), the beneficial
owner of any securities covered by this statement.

         During the past five years, none of the Reporting Persons have been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors), nor have they been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
been subject to a judgment, decree or final order enjoining future violations
of, or prohibiting or mandating activities subject to United States federal or
state securities laws or finding any violation with respect to such laws.

         Item 3.  Source and Amount of Consideration

         The total amount of funds required by CN and Merger Sub to consummate
the Offer and the Merger and to pay related fees and expenses is estimated to be
approximately US$1.8 billion. Merger Sub obtained the necessary funds from
capital contributions and advances made directly or indirectly by CN and the
U.S. Borrower (as defined below), including borrowings under the Credit
Facilities referred to below. CN and certain of its subsidiaries have entered
into two credit agreements each dated as of March 16, 1998 (collectively, the
"Loan Agreements") with Goldman Sachs Canada Credit Partners Co. ("Goldman
Canada"), Goldman Sachs Credit Partners L.P. ("Goldman Credit LP") and Bank of
Montreal ("BMO") and certain other lenders (with Goldman Credit LP, Goldman
Canada and BMO, the "Lenders") pursuant to which the Lenders severally committed
to provide senior credit facilities (the "Credit Facilities") in an aggregate
principal amount of up to US$1.8 billion. A copy of each Loan Agreement is filed
as an exhibit to this filing and is incorporated herein by reference, and the
following summary of the Loan Agreements and the Credit Facilities provided for
herein is qualified in its entirety by reference thereto.

         The borrowers under the Credit Facilities are CN and a U.S. subsidiary
of CN (the "U.S. Borrower" and, together with CN, the "Borrowers"). CN, at its
option, may add other subsidiaries as borrowers under the Credit Facilities. The
Credit Facilities in the aggregate consist of a US$800 million term loan
facility (the "Term Facility") and a US$1 billion revolving credit facility (the
"Revolving Facility"). At the option of CN, a portion of the Revolving Facility
is available in Canadian Dollars. In addition, up to $200 million of the
Revolving Facility will be available for letters of credit. Proceeds of
borrowing under the Credit Facilities are to be used to finance the Offer, will
be used to pay related fees and expenses in connection therewith and with the
Merger, to finance certain outstanding indebtedness of CN and, in the case of
the Revolving Facility only, may also be used for general corporate purposes,
including working capital purposes and commercial paper backstop. On March 24,
1998, CN and the U.S. Borrower will draw down funds under the Term Facility and
the Revolving Facility, which together with existing working capital, will be
used to purchase the shares of IC Common Stock pursuant to the Offer.

     Borrowings under the Credit Facilities will mature, one year in the case of
the Term Facility, or five years in the case of the Revolving Facility, from the
date of initial drawdown under the Credit Facilities, and will bear interest at
a rate per annum equal to, at the option of the Borrowers, (i) the Eurodollar
Rate plus a margin (the "Applicable Margin"), initially expected to be 0.275%
per annum, which will vary based on CN's unsecured long term senior debt rating,
(ii) the Base Rate and (iii) in the case of Revolving Facility borrowings in
Canadian Dollars only, the Canadian Bankers Acceptance Rate plus the Applicable
Margin; provided that during any period when more than $900 million of the
Credit Facilities in the aggregate are drawn and outstanding, the Applicable
Margin shall be increased by 0.05% per annum. The Credit Facilities provide for
a facility fee payable on the aggregate amount of the Revolving Facility
(whether drawn or undrawn) and the aggregate outstanding principal amount of the
loans under the Term Facility at a rate per annum that is initially expected to
be 0.125% and that will vary based on CN's unsecured long term senior debt
rating. The Credit Facilities contain certain negative covenants applicable to
CN and its subsidiaries, including, without limitation, restrictions on liens
and mergers and acquisitions and the following financial covenants; maximum debt
to total capitalization, minimum tangible net worth requirement and, solely if
CN's unsecured long term senior debt ratings remains below a certain threshold,
minimum fixed charge coverage.

         All borrowings and issuances of letters of credit under the Credit
Facilities, including the initial borrowings, are subject to the satisfaction or
waiver of certain conditions, including, without limitation: (i) the accuracy of
representations and warranties, (ii) the absence of any default or event of
default under the Credit Facilities and (iii) the non-occurrence of any material
adverse change in respect of CN or IC.

     Amounts outstanding under the Credit Facilities are cross-guaranteed by CN
and the other Borrower and by all present and future material subsidiaries of
CN, provided that IC and its subsidiaries are not required to provide any such
guarantees until permitted by law to do so and Canadian National Railway
Properties Inc. has provided such guarantee only to the extent permitted by
applicable law for borrowers other than CN. The terms of the Credit Facilities
provide that, while the Voting Trust is in effect, net proceeds generated from
sales of shares of IC Common Stock or from asset sales by IC and its
subsidiaries (subject to certain exceptions) actually received by CN and its
subsidiaries (other than any subsidiaries held through the Voting Trust) are to
be applied first to repay outstandings under the Term Facility and second to
repay outstandings under the Revolving Facility and to reduce commitments
thereunder, unless, in the case of the Revolving Facility, at the time of
receipt of such proceeds CN's unsecured long-term senior debt rating is above a
certain threshold and the commitments under the Revolving Facility do not exceed
US$700 million.

         Pursuant to the Loan Agreements and the commitment letter related
thereto, CN paid certain fees to Goldman Canada, Goldman Credit L.P. and BMO and
has agreed to reimburse the Lenders for certain expenses and to provide certain
indemnities, as is customary for commitments of the type described herein.

         Item 4.  Purpose of the Transaction

         On February 10, 1998, CN, Merger Sub and Illinois Central Corporation
("IC") entered into an Agreement and Plan of Merger (the "Merger Agreement"), as
amended on March 4, 1998, whereby CN will acquire IC for a purchase price of
approximately $1.8 billion payable as to 75% in cash and 25% in common shares of
CN. As a first-step in the acquisition, on February 13, 1998, CN and Merger Sub
launched their cash tender offer (the "Offer") for up to 46,051,761 shares of IC
Common Stock (representing approximately 75% of the outstanding shares of IC) at
a cash price of $39.00 per share. On March 13, 1998, Merger Sub successfully
completed its Offer. The Merger Agreement also provides for a second-step merger
(the "Merger") of Merger Sub with and into IC, with IC, as the surviving
corporation (the "Surviving Corporation"), becoming an indirect wholly-owned
subsidiary of CN. Pursuant to the Merger Agreement, the remaining 25% of the
shares of IC Common Stock not acquired in the Offer will be exchanged for shares
of CN common stock with a value equal to the same cash price paid in the tender
offer, subject to certain collar arrangements.

         Pursuant to the Merger Agreement, the shares of IC Common Stock
acquired in the Offer, as well as those of the Surviving Corporation to be
acquired in the Merger, will be placed, upon completion of the Offer, in an
irrevocable voting trust (the "Voting Trust") pending approval of the
transaction by the United States Surface Transportation Board (the "STB"). CN,
Merger Sub and the Trustee have entered into a voting trust agreement (the
"Voting Trust Agreement") dated as of March 13, 1998, pursuant to which, inter
alia, the Trustee has agreed to act as trustee (the "Trustee") of the Voting
Trust.

         Following the Offer, Merger Sub beneficially owns approximately 74.4%
of the outstanding shares of IC Common Stock. Therefore, Merger Sub (through the
voting trust arrangements) has sufficient voting power under Delaware law to
effect the adoption of the Merger Agreement without the affirmative vote or
written consent of any other IC stockholder. The Merger is expected to be
consummated during the second calendar quarter of 1998.

         Pursuant to the terms of the Merger Agreement, CN and IC will file an
application with the STB prior to the end of the second quarter of 1998 to seek
approval by the STB of CN's acquisition of control of IC. STB approval may take
up to 15 months and CN and IC intend to request the STB to expedite the approval
process. STB approval is expected in early 1999.

         Pursuant to the Merger Agreement, IC has granted registration rights to
CN that entitles CN to three registration rights within three years from the
termination of the Merger Agreement in order to allow CN to sell or dispose of
any or all of the shares held in the Voting Trust.

         Pursuant to the terms of the Merger Agreement, CN will (i) appoint Mr.
E. Hunter Harrison (formerly the President and Chief Executive Officer and a
director of IC) to the position of Chief Operating Officer of CN, and (ii)
appoint Messrs. Gilbert H. Lamphere (formerly IC's Chairman of the Board of
Directors) and Alexander P. Lynch (formerly a director of IC) to the Board of
Directors of CN. Messrs. Lamphere, Lynch and Harrison have resigned from their
positions with IC.

         Pursuant to the terms of the Merger Agreement, and subject to the
rules, regulations and practices of the STB, CN has appointed Mr. Edward D.
Sleven, an individual who was previously identified to IC and reasonably
satisfactory to the Board of Directors of IC, to the Board of Directors of IC
immediately following the resignations of Messrs. Lamphere and Lynch from the
Board of Directors of IC. Mr. Sleven is independent of CN.

         Following the Merger, the shares of IC Common Stock will be delisted
from the NYSE and deregistered under the Exchange Act.

         Item 5.  Interest in the Securities of the Issuer.

         (a) As of March 13, 1998, pursuant to the Offer, Merger Sub had
acquired, and for purposes of Rule 13d-3 promulgated under the Exchange Act may
be deemed to own beneficially, 46,051,761 shares of IC Common Stock,
representing approximately 74.4% of the total number of shares of IC Common
Stock outstanding.

         GTC, as the sole stockholder of Merger Sub, has the power to direct the
voting and disposition by Merger Sub of the shares of IC Common Stock owned by
Merger Sub.

         CN, as the sole stockholder of GTC, has the power to control the
actions of GTC with respect to the voting and disposition of the shares of IC
Common Stock owned by Merger Sub. Accordingly, each of CN, GTC and Merger Sub
may be deemed to have shared voting and dispositive power with respect to the
46,051,761 shares of IC Common Stock beneficially owned by Merger Sub.

         The Trustee, in its capacity as Trustee of the Voting Trust, holds the
46,051,761 shares of IC Common Stock acquired by Merger Sub in the Offer in
trust on behalf of Merger Sub, pursuant to the provisions of the Voting Trust
Agreement. Accordingly, the Trustee may be deemed to have shared voting and
dispositive power with respect to such shares of IC Common Stock beneficially
owned by Merger Sub.

         (b) Except as otherwise described herein, the Reporting Persons do not
have any sole or shared power to vote or to direct the vote of any shares of IC
Common Stock nor sole or shared power to dispose of or direct the disposition of
any shares of IC Common Stock.

         (c) Except for the transactions described in Item 4 hereof, no
transactions in shares of IC Common Stock have been effected during the past 60
days by any Reporting Persons nor by any other person controlling any Reporting
Persons.

         Item 6.  Contracts, Arrangements, Understandings or Relationships With
Respect to Securities of the Issuer.

         In addition to the Voting Trust Agreement and the arrangements
described in Item 4, in connection with the transaction, Mr. Lamphere and Mr.
Lynch have each entered into agreements with CN pursuant to which Messrs.
Lamphere and Lynch have each agreed to roll-over 100% of their existing options
to purchase shares of IC Common Stock into options to purchase shares of CN
Common Stock and to vote their shares of IC Common Stock in favor of the
adoption by the stockholders of the Merger Agreement. Mr. Lamphere has also
agreed to acquire, within 90 days following the date of the consummation of the
Merger, at least 98,150 (including any shares of CN Common Stock received
pursuant to the Merger) shares of CN common stock; provided that Mr. Lamphere is
not obligated to invest an amount in excess of $7,000,000 (including the spread
value of the options rolled-over to CN options). Any required acquisitions of
shares by Mr. Lamphere (other than pursuant to the Merger) will be made in the
open market at market prices.

         Except for the agreements described above, to the best knowledge of the
Reporting Persons, there are no contracts, arrangements, understandings or
relationships (legal or otherwise) between the persons enumerated in Item 2, and
any other person, with respect to any securities of IC, including, but not
limited to, transfer or voting of any of the securities, finder's fees, joint
ventures, loan or option arrangements, puts or calls, guarantees of profits,
division of profits or, or the giving or withholding of proxies.

         THIS VOTING TRUST AGREEMENT, dated as of March 13, 1998, by and among
Canadian National Railway Company, a Canadian corporation ("Parent"), Blackhawk
Merger Sub, a Delaware corporation and an indirect wholly owned subsidiary of
Parent ("Merger Subsidiary") and The Bank of New York, a New York banking
corporation (the "Trustee"),

                              W I T N E S S E T H:

         WHEREAS, it is intended that Merger Subsidiary will commence and
complete a cash tender offer (the "Offer") for up to an aggregate of [ ]
outstanding shares of common stock ("Shares") of Blackhawk, a Delaware
corporation (the "Company") to be followed by a merger of Merger Subsidiary with
and into the Company (the "Merger") pursuant to, and upon the terms and
conditions set forth in, the Agreement and Plan of Merger dated as of February
16, 1998 among the Company, Parent and Merger Subsidiary, as it may be amended
from time to time (the "Merger Agreement") (a copy of which is attached hereto
as Exhibit A);

         WHEREAS, it is intended that the consummation of the Merger will occur
prior to any issuance by the Surface Transportation Board (the "STB") of any
required approval for, or exemption of, Parent's control of the Company;

         WHEREAS, Parent and Merger Subsidiary intend, simultaneously with the
acquisition of the Shares of the Company pursuant to the Offer and pursuant to
the Merger (the corporation surviving the Merger also referred to herein as the
"Company"), to cause the deposit of such shares in an independent, irrevocable
voting trust, pursuant to the rules of the STB, in order to avoid any allegation
or assertion that Parent or any of its affiliates is controlling or has the
power to control the Company prior to the receipt of any required STB approval
or exemption;

         WHEREAS, neither the Trustee nor any of its affiliates has any officers
or board members in common or any direct or indirect business arrangements or
dealings (as described in Paragraph 9 hereof) with Parent or any of its
affiliates; and

         WHEREAS, the Trustee is willing to act as voting trustee pursuant to
the terms of this Trust Agreement and the rules of the STB,

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Parent and Merger Subsidiary hereby appoint The Bank of New York as
Trustee hereunder, and The Bank of New York hereby accepts said appointment and
agrees to act as Trustee under this Trust Agreement as provided herein.

         2. Parent and Merger Subsidiary agree that, prior to acceptance of any
tendered Shares pursuant to the Offer, Merger Subsidiary will direct the
depositary for the offer to transfer to the Trustee any Shares accepted for
payment pursuant to the Offer. Parent and Merger Subsidiary also agree that
immediately upon receipt, acquisition or purchase by either of them or by any of
their affiliates of any additional Shares, or any other voting securities of the
Company, it will transfer or cause to be transferred to the Trustee the
certificate or certificates representing such additional Shares or other
securities. Parent also agrees that, simultaneously with the effectiveness of
the Merger, Parent will cause the transfer to the Trustee of the certificate or
certificates representing 100 percent of the issued and outstanding shares of
the Company, as the corporation surviving the Merger. All such certificates
shall be duly endorsed or accompanied by proper instruments duly executed for
transfer thereof to the Trustee, and shall be exchanged for one or more Voting
Trust Certificates substantially in the form attached hereto as Attachment A
(the "Trust Certificates"), with the blanks therein appropriately filled. All
Shares at any time delivered to the Trustee hereunder are hereinafter called the
"Company Trust Stock." The Trustee shall present to the Company all certificates
representing Company Trust Stock for surrender and cancellation and for the
issuance and delivery to the Trustee of new certificates (the "Trust Stock")
registered in the name of the Trustee or its nominee.

         3. The Trustee shall be present, in person or represented by proxy, at
all annual and special meetings of shareholders of the Company so that all Trust
Stock may be counted for the purposes of determining the presence of a quorum at
such meetings. The Trustee shall be entitled and it shall be its duty to
exercise any and all voting rights in respect of the Trust Stock either in
person or by proxy or consent, as hereinafter provided, unless otherwise
directed by an order of the STB or a court of competent jurisdiction. Parent and
Merger Subsidiary agree, and the Trustee acknowledges, that the Trustee shall
not participate in or interfere with the management of the Company and shall
take no other actions with respect to the Company except in accordance with the
terms hereof. The Trustee shall exercise all voting rights in respect of the
Trust Stock in favor of any proposal or action necessary or desirable to effect,
or consistent with the effectuation of, the acquisition of the Company by Parent
and Merger Subsidiary pursuant to the Merger Agreement and, without limiting the
generality of the foregoing, if there shall be with respect to the Board of
Directors of the Company an "Election Contest" as defined in the Proxy Rules of
the Securities and Exchange Commission (the "SEC"), in which one slate of
nominees shall support the effectuation of the Merger and another oppose it,
in favor of the slate supporting the effectuation of the Merger. In addition,
for so long as the Merger Agreement is in effect, the Trustee shall vote all
shares of Trust Stock to cause any other proposed merger, business combination
or similar transaction (including, without limitation, any consolidation, sale
of all or substantially all the assets, reorganization, recapitalization,
liquidation or winding up of or by the Company) involving the Company, but not
involving Parent or one of its affiliates (other than in connection with a
disposition pursuant to paragraph 8), not to be effected. The Trustee shall vote
all shares of Trust Stock in favor of any proposal or action necessary or
desirable to dispose of Trust Stock in accordance with Paragraph 8 hereof.
Except as otherwise expressly provided in the three immediately preceding
sentences, the Trustee shall vote all shares of Trust Stock with respect to all
matters, including, without limitation, the election or removal of directors,
voted on by the shareholders of the Company (whether at a regular or special
meeting or pursuant to a unanimous written consent) in the Trustee's sole
discretion, having due regard for the interests of the holders of the Trust
Certificates as investors in the Company, determined without reference to such
holders' interests in railroads other than the Company or its subsidiaries;
provided that the Trustee shall not vote the Trust Stock in favor of taking or
doing any act which would violate any provision of the Merger Agreement or
impede the Company's performance thereunder or which if taken or done prior to
the consummation of the Merger would have been a violation of the Merger
Agreement. Notwithstanding the foregoing provisions of this Paragraph 3 or any
other provision of this Agreement, the registered holder of a Trust Certificate
may at any time -- but only with the prior written approval of the STB --
instruct the Trustee in writing to vote the Trust Stock represented by such
Trust Certificate in any manner, in which case the Trustee shall vote such
shares in accordance with such instructions. In exercising its voting rights in
accordance with this Paragraph 3, the Trustee shall take such actions at all
annual, special or other meetings of stockholders of the Company or in
connection with any action by consent in lieu of a meeting.

         4. This Trust Agreement and the nomination of the Trustee during the
term of the trust shall be irrevocable by Parent and its affiliates and shall
terminate only in accordance with the provisions of Paragraphs 8 and 14 hereof.

         5. Subject to Paragraph 3, the Trustee shall not exercise the voting
powers of the Trust Stock in any way so as to create any dependence or
intercorporate relationship between (i) Parent and its affiliates, on the one
hand, and (ii) the Company or its affiliates, on the other hand. The term
"affiliate" or "affiliates" wherever used in this Trust Agreement shall have the
meaning specified in Section 11323(c) of Title 49 of the United States Code, as
amended. The Trustee shall not, without the prior approval of the STB, vote the 
Trust Stock to elect any officer, director, nominee or representative of Parent
or any of its affiliates as an officer or director of the Company or of any
affiliate of the Company. The Trustee shall be kept informed respecting the
business operations of the Company by means of the financial statements and
other public disclosure documents periodically filed by the Company and
affiliates of the Company with the SEC and with the STB, and by means of
information respecting the Company contained in such statements and other
documents filed by Parent with the SEC and the STB, copies of which shall be
promptly furnished to the Trustee by the Company or Parent, as the case may be,
and the Trustee shall be fully protected in relying upon such information. The
Trustee shall not be liable for any mistakes of fact or law or any error of
judgment, or for any act or omission, except as a result of the Trustee's
willful misconduct or gross negligence.

         6. All Trust Certificates shall be transferable on the books of the
Trustee by the registered holder upon the surrender thereof properly assigned,
in accordance with rules from time to time established for the purpose by the
Trustee. Until so transferred, the Trustee may treat the registered holder as
owner for all purposes. Each transferee of a Trust Certificate issued hereunder
shall, by his acceptance thereof, assent to and become a party to this Trust
Agreement, and shall assume all attendant rights and obligations.

         7. Pending the termination of this Trust as hereinafter provided, the
Trustee shall, immediately following the receipt of each cash dividend or cash
distribution as may be declared and paid upon the Trust Stock, pay the same over
to or as directed the registered holder(s) of Trust Certificates hereunder as
then known to the Trustee. The Trustee shall receive and hold dividends and
distributions other than cash upon the same terms and conditions as the Trust
Stock and shall issue Trust Certificates representing any new or additional
securities that may be paid as dividends upon the Trust Stock or otherwise
distributed upon the Trust Stock to the registered holder(s) of Trust
Certificates in proportion to their respective interests.

         8. (a) This Trust is accepted by the Trustee subject to the right
hereby reserved in Parent at any time to sell or make any other disposition of
the whole or any part of the Trust Stock, whether or not an event described in
subparagraph (b) below has occurred. The Trustee shall take all actions
reasonably requested by Parent with respect to (including, without limitation,
exercising all voting rights in respect of Trust Stock in favor of any proposal
or action necessary or desirable to effect, or consistent with the effectuation
of) any proposed sale or other disposition of the whole or any part of the Trust
Stock by Parent. The Trustee shall at any time upon the receipt of a direction
from Parent signed by its President or one of its Vice Presidents and under its
corporate seal designating the person or entity to whom Parent has directly or
indirectly sold or otherwise disposed of the whole or any part of the Trust
Stock and certifying that such person or entity is not an affiliate of Parent
and has all necessary regulatory authority, if any be required, to purchase the
Trust Stock (upon which certification the Trustee shall be entitled to rely),
immediately transfer to the person or entity therein named all the Trustee's
right, title and interest in such amount of the Trust Stock as may be set forth
in said direction. If the foregoing direction shall specify all of the Trust
Stock, then following transfer of the Trustee's right, title and interest
therein, and in the event of a sale thereof, upon delivery to or upon the order
of the registered holder(s) of the Trust Certificates of the proceeds of such
sale, this Trust shall cease and come to an end. If the foregoing direction is
as to only a part of the Trust Stock, then this Trust shall cease as to said
part upon such transfer, and distribution of the net proceeds therefrom in the
event of sale, but shall remain in full force and effect as to the remaining
part of the Trust Stock. In the event of a direct or indirect sale of Trust
Stock by Parent, the Trustee shall, to the extent the consideration therefor is
payable to or controllable by the Trustee, promptly pay, or cause to be paid
upon the order of Parent the net proceeds of such sale on a pro rata basis to
the registered holder(s) of the Trust Certificates. It is the intention of this
paragraph that no violations of 49 U.S.C. Sections 11323 will result from a
termination of this Trust.

                  (b) In the event the STB Approval (as defined below) shall
have been granted, then immediately upon the direction of Parent and the
delivery of a certified copy of such order of the STB or other governmental
authority with respect thereof, or, in the event that Subtitle IV of Title 49 of
the United States Code, or other controlling law, is amended to allow Parent or
its affiliates to acquire control of the Company without obtaining STB or other
governmental approval, upon delivery of an opinion of independent counsel
selected by the Trustee that no order of the STB or other governmental authority
is required, the Trustee shall either (i) transfer to or upon the order of the
registered holder(s) of Trust Certificates hereunder as then known to the
Trustee, its right, title and interest in and to all of the Trust Stock then
held by it in accordance with the terms, conditions and agreements of this Trust
Agreement and not theretofore transferred by it as provided in subparagraph (a)
hereof, or (ii) if shareholder approval of the Merger has not previously been
obtained, vote the Trust Stock with respect to the Merger or any other merger
between the Company and Merger Subsidiary or any other affiliate of Parent as
directed by the registered holder(s) of the Trust Certificates; and upon any
such transfer or merger this Trust shall cease and come to an end.

                  (c) In the event that there shall have been an STB Denial (as
defined below), Parent shall use its best efforts to sell the Trust Stock to one
or more eligible purchasers, or otherwise to dispose of the Trust Stock, during
a period of two years after such STB Denial or such extension of that period as
the STB shall approve. Any such disposition shall be subject to any jurisdiction
of the STB to oversee Parent's divestiture of Trust Stock. At all times, the
Trustee shall continue to perform its duties under this Trust Agreement and,
should Parent be unsuccessful in its efforts to sell or distribute the Trust
Stock during the period referred to, the Trustee shall as soon as practicable
sell the Trust Stock for cash to one or more eligible purchasers in such manner
and for such price as the Trustee in its discretion shall deem reasonable after
consultation with the Parent. (An "eligible purchaser" hereunder shall be a
person or entity that is not affiliated with the Parent and which has all
necessary regulatory authority, if any be required, to purchase the Trust
Stock.) Parent agrees to cooperate with the Trustee in effecting such
disposition, and the Trustee agrees to act in accordance with any direction made
by Parent as to any specific terms or method of disposition, to the extent not
inconsistent with the requirements of the terms of any STB or court order. The
proceeds of the sale shall be distributed on a pro rata basis to or upon the
order of the registered holder(s) of the Trust Certificates hereunder as then
known to the Trustee. The Trustee may, in its reasonable discretion, require the
surrender to it of the Trust Certificates hereunder before paying to the holder
his share of the proceeds. Upon disposition of the Trust Stock pursuant to this
Paragraph 8(c), this Trust shall cease and come to an end.

                  (d) Unless sooner terminated pursuant to any other provision
herein contained, this Trust Agreement shall terminate on March 13, 2003, and
may be extended by the parties hereto, so long as no violation of 49 U.S.C.
Sections 11323 will result from such termination or extension. All Trust Stock
and any other property held by the Trustee hereunder upon such termination shall
be distributed on a pro rata basis to or upon the order of the registered
holder(s) of Trust Certificates hereunder as then known to the Trustee. The
Trustee may, in its reasonable discretion, require the surrender to it of the
Trust Certificates hereunder before the release or transfer of the stock
interests evidenced thereby.

                  (e) The Trustee shall promptly inform the STB of any transfer
or disposition of Trust Stock pursuant to this Paragraph 8.

                  (f) Except as provided in this Paragraph 8, the Trustee shall
not dispose of, or in any way encumber, the Trust Stock.

                  (g) Notwithstanding the foregoing, if the STB issues a
declaratory order that the termination of the Trust will not cause Parent or its
affiliates to have control of the Company, the Trustee shall transfer on a pro
rata basis to or upon the order of the registered holder(s) of Trust
Certificates hereunder as then known to the Trustee, its right, title and
interest in and to all of the Trust Stock then held by it in accordance with the
terms and conditions of this Trust Agreement and not theretofore transferred by
it as provided in subparagraph (a) hereof, and this Trust shall cease and come
to an end. The Trustee may, in its reasonable discretion, require the surrender
to it of the Trust Certificates hereunder before the release or transfer of the
stock interests evidenced thereby.

                  (h) As used in this Paragraph 8, the terms "STB Approval" and
"STB Denial" shall have the following meanings:

                           "STB Approval" means the issuance by the STB of a
                  decision, which decision shall become effective and which
                  decision shall not have been stayed or enjoined, that (A)
                  constitutes a final agency action approving, exempting or
                  otherwise authorizing the acquisition of control over the
                  Company's railroad operations by Parent and its affiliates,
                  without the imposition of conditions that Parent, by written
                  notice to the Trustee, has deemed to be unacceptable, and (B)
                  does not require any change in the consideration paid or to be
                  paid pursuant to the Merger Agreement or other material
                  provisions thereof, unless Parent, by written notice to the
                  Trustee, has determined any such change to be acceptable to
                  Parent.

                           "STB Denial" means (i) STB Approval shall not have
                  been obtained by December 31, 2000 or (ii) the STB shall
                  have, by an order which shall have become final and no longer
                  subject to review by the courts, refused to approve the
                  control referred to in clause (A) of the definition of STB
                  Approval.

         9. Neither the Trustee nor any affiliate of the Trustee may have (i)
any officers, or members of their respective boards or directors, in common with
Parent or any of its affiliates, or (ii) any direct or indirect business
arrangements or dealings, financial or otherwise, with Parent or any of its
affiliates, other than dealings pertaining to establishment and carrying out of
this Trust. Mere investment in the stock or securities of Parent or any of its
affiliates by the Trustee, short of obtaining a controlling interest, will not
be considered a proscribed business arrangement or dealing, but in no event
shall any such investment by the Trustee in voting securities of Parent or its
affiliates exceed 5 percent of their outstanding voting securities; and in no
event shall the Trustee hold a proportion of such voting securities so
substantial as to permit the Trustee in any way to control or direct the affairs
of Parent or its affiliates. Neither Parent nor its affiliates shall purchase
the stock or securities of the Trustee or any affiliate of the Trustee.

         10. The Trustee shall be entitled to receive reasonable and customary
compensation for all services rendered by it as Trustee under the terms hereof,
and said compensation to the Trustee, together with all counsel fees, taxes, or
other expenses reasonably incurred hereunder, shall be promptly paid by Parent.

         11. The Trustee may at any time or from time to time appoint an agent
or agents and may delegate to such agent or agents the performance of any
administrative duty of the Trustee and be entitled to reimbursement for the fees
and expenses of such agents.

         12. The Trustee shall not be answerable for the default or misconduct
of any agent or attorney appointed by it in pursuance hereof if such agent or
attorney shall have been selected with reasonable care. The duties and
responsibilities of the Trustee shall be limited to those expressly set forth in
this Trust Agreement. The Trustee shall be fully protected by acting in reliance
upon any notice, advice, direction or other document or signature believed by
the Trustee to be genuine. The Trustee shall not be responsible for the
sufficiency or accuracy of the form, execution, validity or genuineness of the
Trust Stock, or of any other documents, or of any endorsement thereon, or for
any lack of endorsement thereon, or for any description therein, nor shall the
Trustee be responsible or liable in any respect on account of the identity,
authority or rights of the persons executing or delivering or purporting to
execute or deliver any such Trust Stock or other document or endorsement or this
Trust Agreement, except for the execution and delivery of this Trust Agreement
by this Trustee. The Parent agrees that it will at all times protect, indemnify
and save harmless the Trustee from any loss, damages, liability, cost or expense
of any kind or character whatsoever in connection with this Trust, except those,
if any, resulting from the gross negligence or willful misconduct of the
Trustee, and will at all times undertake, assume full responsibility for, and
pay on a current basis, but at least quarterly, all cost and expense of any suit
or litigation of any character, whether or not involving a third party,
including any proceedings before the STB, with respect to the Trust Stock or
this Trust Agreement, and if the Trustee shall be made a party thereto, or be
the subject of any investigation or proceeding (whether formal or informal), the
Parent will pay all costs, damages and expenses, including reasonable counsel
fees, to which the Trustee may be subject by reason thereof; provided, however,
that Parent shall not be responsible for the cost and expense of any suit that
the Trustee shall settle without first obtaining Parent's written consent. The
indemnification obligations of Parent shall survive any termination of this
Trust Agreement or the removal, resignation or other replacement of the Trustee.
The Trustee may consult with counsel selected by it and the opinion of such
counsel shall be full and complete authorization and protection in respect of
any action taken or omitted or suffered by the Trustee hereunder in good faith
and in accordance with such opinion.

         13. To the extent requested to do so by Parent, Merger Subsidiary or
any registered holder of a Trust Certificate, the Trustee shall furnish to the
party making such request full information with respect to (i) all property
theretofore delivered to it as Trustee, (ii) all property then held by it as
Trustee, and (iii) all action theretofore taken by it as Trustee.

         14. The Trustee, or any trustee hereafter appointed, may at any time
resign by giving sixty days' written notice of resignation to Parent, Merger
Subsidiary and the STB. Parent shall at least fifteen days prior to the
effective date of such notice appoint a successor trustee which shall (i)
satisfy the requirements of Paragraph 9 hereof and (ii) be a corporation
organized and doing business under the laws of the United States or of any State
thereof and authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state authority. If no successor
trustee shall have been appointed and shall have accepted appointment at least
fifteen days prior to the effective date of such notice of resignation, the
resigning Trustee may petition any authority or court of competent jurisdiction
for the appointment of a successor trustee. Upon written assumption by the
successor trustee of the Trustee's powers and duties hereunder a copy of the
assumption shall be delivered by the Trustee to Parent and to Merger Subsidiary,
and the STB and all registered holders of Trust Certificates shall be notified
of such assumption, whereupon the Trustee shall be discharged of its powers and
duties hereunder and the successor trustee shall become vested therewith. In the
event of any material violation by the Trustee of the terms and conditions of
this Trust Agreement, the Trustee shall become disqualified from acting as
trustee hereunder as soon as a successor trustee shall have been selected in the
manner provided by this paragraph.

         15. This Trust Agreement may from time to time be modified or amended
by agreement executed by the Trustee, Parent, Merger Subsidiary and to the
registered holder(s) of the Trust Certificates (i) pursuant to an order of the
STB, (ii) with the prior approval of the STB, (iii) in order to comply with any
order of the STB, or (iv) upon receipt of an opinion of counsel satisfactory to
the Trustee and the registered holder(s) of Trust Certificates that an order of
the STB approving such modification or amendment is not required and that the
amendment is authorized under the Merger Agreement and is consistent with the
regulations of the STB regarding voting trusts.

         16. The provisions of this Trust Agreement and the rights and
obligations of the parties hereunder shall be governed by the laws of the State
of Delaware, except that, to the extent any provision hereof may be found
inconsistent with the ICC Termination Act of 1995 or regulation promulgated
thereunder by the STB, such Act and regulations shall control and such provision
hereof shall be given effect only to the extent permitted by such Act and
regulations. In the event that the STB shall, at any time hereafter by final
order, find that compliance with law requires any other or different action by
the Trustee than is provided herein, the Trustee shall act in accordance with
such final order instead of the provisions of this Trust Agreement.

         17. This Trust Agreement is executed in three counterparts, each of
which shall constitute an original, and one of which shall be retained by
Parent, one by Merger Subsidiary, and the other by the Trustee.

         18. A copy of this Agreement and any amendments or modifications
thereto shall be filed with the STB by Parent.

         19. This Trust Agreement shall be binding upon the successors and
assigns to the parties hereto, including without limitation successors to Parent
by merger, consolidation or otherwise.

         20. For purposes of this Trust Agreement, the term "Surface
Transportation Board" or "STB", includes any successor agency or governmental
department that is authorized to carry out the responsibilities now carried out
by the STB with respect to voting trusts and control of common carriers.

         21. (a) Any notice or other communication required or permitted to be
given hereunder shall be in writing and shall be mailed by U.S. mail, certified
mail, return receipt requested or by Federal Express, Express Mail, or similar
overnight delivery or courier service or delivered (in person or by telecopy)
against receipt to the party to whom it is to be given at the address of such
party set forth below (or to such other address as the party shall have given
notice of):

                  (b) Unless otherwise specifically provided herein, any notice
to or communication with the registered holder(s) of the Trust Certificates
hereunder shall be deemed to be sufficiently given or made if enclosed in
postpaid envelopes (regular not registered mail) addressed to such holders at
their respective addresses appearing on the Trustee's transfer books, and
deposited in any post office or post office box. The addresses of the holders of
Trust Certificates, as shown on the Trustee's transfer books, shall in all cases
be deemed to be the addresses of Trust Certificate holders for all purposes
under this Trust Agreement, without regard to what other or different addresses
the Trustee may have for any Trust Certificate holder on any other books or
records of the Trustee. Every notice so given of mailing shall be the date such
notice is deemed given for all purposes.

         22. Each of the parties hereto acknowledges and agrees that in the
event of any breach of this Agreement, the non-breaching party would be
irreparably and immediately harmed and could not be made whole by monetary
damages. It is accordingly agreed that the parties hereto (a) will waive, in any
action for specific performance, the defense of adequacy of a remedy at law and
(b) shall be entitled, in addition to any other remedy to which they may be
entitled at law or in equity, to compel specific performance of this Agreement
in any action instituted in any state or federal court sitting in Wilmington,
Delaware. Each party hereto consents to personal jurisdiction in any such action
brought in any state or federal court sitting in Wilmington, Delaware.

                             PRELIMINARY STATEMENTS:

                  A. The Borrower has caused the formation of, and indirectly
owns all of the outstanding shares of capital stock of, Merger Sub (this and
other capitalized terms used in these Preliminary Statements without definition
being used as defined in Section 1.1) for the purpose of acquiring not less than
50.1% (on a fully diluted basis) of the outstanding shares of common stock, par
value US$0.001 per share, of Illinois Central Corporation, a Delaware
corporation (together with its successors, including without limitation, the
survivor to the Merger, "Target") (such common stock being the "Target Common
Stock").

                  B. Merger Sub has offered to purchase not less than 50.1% (on
a fully diluted basis) and not more than 46,051,761 of the issued and
outstanding shares of Target Common Stock at a price equal to US$39.00 per share
pursuant to the Tender Offer.

                  C. Simultaneously with the purchase of the Target Common
Stock, such Target Common Stock purchased by Merger Sub will be deposited into
the Voting Trust established pursuant to the Voting Trust Agreement.

                  D. The Borrower, Merger Sub and Target have entered into the
Merger Agreement pursuant to which, upon completion of the Tender Offer and,
with respect to clauses (1), (2) and (3) below, upon receipt of the approval by
holders of at least 50.1% of the outstanding shares of Target Common Stock (if
required by law):

                           (1) Merger Sub will merge with Target pursuant to the
         Merger Agreement with Target being the surviving corporation in such
         merger (such surviving corporation is sometimes referred to herein as
         the "Surviving Corporation");

                           (2) If Merger Sub has purchased 46,051,761 shares of
         Target Common Stock, each of the shares of Target Common Stock
         outstanding immediately before the consummation of the Merger (other
         than shares to be cancelled as described in clause (4) below and shares
         held by those who perfect appraisal rights, if any, under state law)
         will be converted into the right to receive a number of common shares,
         without par value, of the Borrower (the "Borrower Common Stock")
         determined in accordance with the Merger Agreement;

                           (3) If Merger Sub has purchased less than 46,051,761
         shares of Target Common Stock, each of the shares of Target Common
         Stock outstanding immediately before the consummation of the Merger
         (other than shares to be cancelled as described in clause (4) below and
         shares held by those who perfect appraisal rights, if any, under state
         law) will be converted into the right to receive (x) a number of shares
         of Borrower Common Stock determined in accordance with the Merger
         Agreement and (y) a cash payment in an amount determined in accordance
         with the Merger Agreement;

                           (4) Each of the shares of Target Common Stock
         outstanding immediately before the consummation of the Merger held by
         Merger Sub, Target or any of their respective direct or indirect
         Subsidiaries (including shares held in the Voting Trust) (the "Other
         Target Shares") shall be cancelled and retired without payment of any
         consideration therefor;

                           (5) As a result of the Merger, each of the shares of
         the capital stock of Merger Sub outstanding immediately before the
         consummation of the Merger will be converted into and become one fully
         paid and nonassessable share of common stock of Surviving Corporation
         (the "Surviving Corporation Common Stock"); and

                           (6) Following the Merger, all of the outstanding
         shares of Surviving Corporation Common Stock shall be deposited into
         and subject to the provisions of the Voting Trust unless and until the
         STB approves the acquisition of control of Target by the Borrower.

                  E. The Borrower desires that Lenders extend certain credit
facilities to the Borrower to provide (together with cash on hand of the
Borrower and the proceeds of borrowings on the Initial Funding Date under the US
Credit Agreement) for (i) the payment by Merger Sub of the cash consideration

are necessary for the ownership, maintenance and operation of its properties and
assets and the conduct of its business as now conducted and as proposed to be

violation of any thereof, which failure to possess or violation could have a
Material Adverse Effect;

         2.1.21 each Canadian Plan is in compliance in all material respects

requirements applicable thereto, or relating to the administration or
termination of any Canadian Plan and no event has occurred and no condition

Subsidiaries will incur liabilities on account of the foregoing circumstances
which are material in the aggregate. Except as disclosed in Schedule 2.1.21, no
Canadian Plan is a Deficient Canadian Plan;

         2.1.22 each of the Borrower and each ERISA Affiliate of the Borrower

with the presently applicable provisions of ERISA and the Code with respect to
each Plan except for failures to comply which could not, singularly or in the

Affiliate of the Borrower has (x) sought a waiver of the minimum funding
standard under Section 412 of the Code in respect of any Plan, (y) failed to

posting of a bond or other security under ERISA or the Code, or (z) incurred any
liability under Title IV of ERISA, other than a liability to the PBGC for
premiums under Section 4007 of ERISA, which could in any case have a Material
Adverse Effect. No Prohibited Transaction and no Reportable Event has occurred
with respect to any such Plan within the past five (5) years which could have a
Material Adverse Effect. The execution, delivery and performance of this
Agreement does not constitute a Prohibited Transaction. Except as disclosed in
Schedule 2.1.22, there is no material unfunded benefit liability with respect to
any Plan of the Borrower or its ERISA Affiliates which could have a Material
Adverse Effect. Except to the extent required under Section 4980B of the Code

representations and warranties given by the Borrower and Merger Sub in the
Merger Agreement is true and correct in all material respects as of the date
hereof (or as of any earlier date to which such representation and warranty
specifically relates) and will be true and correct in all material respects as
of the Initial Funding Date (or such earlier date as the case may be), and to
the Borrower's actual knowledge, each representation and warranty made by Target
in the Merger Agreement is true and correct as of the date hereof (or as of any
earlier date to which such representation or warranty specifically relates) and
will be true and correct as of the Initial Funding Date;

         2.1.27 notwithstanding anything in the Merger Agreement to the
contrary, the representations and warranties of the Borrower set forth in
subsection 2.1.26 shall, solely for purposes of this Agreement, survive the
Initial Funding Date for the benefit of Lenders; and

         2.1.28 the Tender Offer Materials and other information furnished by
any Loan Party to any Agent or any Lender for purposes of or in connection with
this Agreement or any transaction contemplated hereby (including any such
information contained in the Confidential Information Memorandum with respect to

omits to state a material fact (known to any Loan Party, in the case of any
document not furnished by it) necessary in order to make the statements
contained therein not misleading in light of the circumstances in which the same

Financial Projections and the Pro Forma Closing Balance Sheet are based upon
good faith estimates and assumptions believed by the Borrower to be reasonable
at the time made, it being recognized by Lenders that such projections as to
future events are not to be viewed as facts and that actual results during the
period or periods covered by any such projections may differ from the projected
results. As of the date hereof, there are no facts known (or which should upon
the reasonable exercise of diligence be known) to any Loan Party (other than
matters of a general economic nature) that, individually or in the aggregate,
could reasonably be expected to result in a Material Adverse Effect and that
have not been disclosed herein or in other documents, certificates and
statements furnished to Lenders for use in connection with the transactions
contemplated hereby.

         The representations and warranties herein set forth or contained in any
certificates or documents delivered to the Administrative Agent or the Lenders
pursuant hereto shall not be prejudiced by and shall survive any accommodation
hereunder and shall continue in full force and effect until the full payment and

furnished its audited annual consolidated statements to the Administrative Agent
pursuant to Section 11.1.2, shall be deemed to be repeated upon each Drawdown
Date (other than a Drawdown Date on which there is no increase in the amount of
credit extended under this Agreement), on the date of each Bid Borrowing and on
the date each Money Market Loan is made.

Loan Commitment in USDollars by way of Libor Advances and Canadian Base Rate
Advances in a minimum amount of ten million USDollars (US$10,000,- 000) or such
larger amount as is an integral multiple of one million USDollars (US$1,000,000)
(or the remaining balance of the Available Term Loan Commitment, if less than
such amount), provided that in no event shall the principal amount of the Term
Loans made to the Borrower exceed US$480,000,000. In each Notice of Borrowing in
which the Borrower has elected to pay interest at a margin or margins relative
to LIBOR on all or part of the Borrowing, the Borrower shall specify the
duration it selects for the initial Interest Period with respect to such Libor

may make only one Borrowing under the Term Loan Commitments. Amounts borrowed
under this Section 3.3.1 and subsequently repaid or prepaid may not be
reborrowed.

written notice in accordance with Section 3.6 by means of a Notice of Borrowing,
the Borrower may from time to time borrow from each Lender up to the amount of
its Available Revolving Loan Commitment by way of Bankers' Acceptances (or as
the case may be, BA Equivalent Advances), Canadian Rate Advances, Canadian Base
Rate Advances or Libor Advances in a minimum amount of ten million CDollars
(C$10,000,000) or ten million USDollars (US$10,000,000) or such larger amount as
is an integral multiple of one million CDollars (C$1,000,000) or one million
USDollars (US$1,000,000) respectively (or the remaining balance of the Available
Revolving Loan Commitment, if less than such amount), provided that in no event
shall the Total Utilization of Revolving Loan Commitments (after giving effect
to any Money Market Reduction) in respect of the Borrower exceed the aggregate
Revolving Loan Commitments of all Lenders. In each Notice of Borrowing in which
the Borrower has elected to pay interest at a margin or margins relative to
LIBOR on all or part of the Borrowing, the Borrower shall specify the duration
it selects for the initial Interest Period with respect to such Libor Loan
Portion in accordance with Section 5.5. In each Notice of Borrowing in which the

3.4      Bid Advances

         3.4.1 Each Lender severally agrees that the Borrower may make Bid
Borrowings under this Section 3.4 from time to time on any Business Day during
the period from the Initial Funding Date until the date occurring one (1) month
(or, in the case of Fixed Rate Advances, thirty (30) days) prior to the
Revolving Loan Commitment Termination Date in the manner set forth below;
provided that (i) no Bid Borrowing may be requested or made until such time as
US$1,700,000,000 in original aggregate principal amount of Advances, US Term
Loans and US Revolving Loans have been made under this Agreement and the US
Credit Agreement and (ii) following the making of each Bid Borrowing, the Total

Market Reduction) shall not exceed the aggregate Revolving Loan Commitments of
all Lenders.

                  (i) The Borrower may request a Bid Borrowing under this
         Section 3.4 by delivering to the Administrative Agent, by telecopier,
         confirmed immediately in writing, not later than 10:00 a.m. (Montreal
         time) (A) at least three (3) Business Days prior to the date of the

         or (B) at least four (4) Business Days prior to the date of the




                                       43

<PAGE>



         proposed Bid Borrowing, if the Borrower selects a Libor Advance, a
         notice of a Bid Borrowing (a "Notice of Bid Borrowings"), in
         substantially the form of Schedule 3.4.1, specifying therein if the
         Borrower selects a Fixed Rate Advance or a Libor Advance, the date and
         aggregate amount of the proposed Bid Borrowing, the maturity date for
         repayment of each Bid Advance to be made as part of such Bid Borrowing
         (which maturity date may not be earlier than the date occurring one (1)
         month (or, in the case of Fixed Rate Advances, thirty (30) days) after
         the date of such Bid Borrowing or, in any case, may not be later than
         one hundred and eighty (180) days after the date of such Bid Borrowing,
         or, if earlier, the Revolving Loan Commitment Termination Date), the
         interest payment date or dates relating thereto, the right, if any, to
         prepay any principal amount of any Bid Advance to be made a part of
         such Bid Borrowing on such terms as the Borrower shall therein specify,
         and any other terms to be applicable to such Bid Borrowing. The
         Administrative Agent shall in turn promptly notify each Lender of each
         request for a Bid Borrowing received by it from the Borrower by sending
         such Lender a copy of the related Notice of Bid Borrowing.

                  (ii) Each Lender may, if, in its sole discretion, it elects to
         do so, irrevocably offer to make one or more Bid Advances to the
         Borrower as part of such proposed Bid Borrowing at a fixed rate or
         rates, or a margin or margins relative to LIBOR, as requested by the
         Borrower, by notifying the Administrative Agent via telecopier (which
         shall give prompt notice thereof to the Borrower), (A) after 9:00 a.m.
         but before 9:30 a.m. (Montreal time) on the date of such proposed Bid
         Borrowing, in the case of a Notice of Bid Borrowing for a Fixed Rate
         Advance and (B) after 1:30 p.m. but before 2:00 p.m. (Montreal time)
         three (3) Business Days before the date of such proposed Bid Borrowing,
         in the case of a Notice of Bid Borrowing for a Libor Advance, of the
         minimum amount (which amount shall be not less than C$1,000,000 for Bid
         Advances in C$ and not less than US$1,000,000 for Bid Advances in US$)
         and maximum amount of each Bid Advance which such Lender would be
         willing to make as part of such proposed Bid Borrowing (which amounts
         may, subject to the proviso to the first sentence of Section 3.4.1,
         exceed such Lender's Revolving Loan Commitment), the fixed rate or
         rates, or a margin or margins relative to LIBOR, as requested by the
         Borrower, which such Lender would be willing to accept for such Bid
         Advance and such Lender's Applicable Lending Office with respect to
         such Bid Advance; provided that if the Administrative Agent in its
         capacity as a Lender shall, in its sole discretion, elect to make any
         such offer, it shall notify the Borrower of such offer by 9:00 a.m.
         (Montreal time) on the date of such proposed Bid Borrowing, in the case
         of a Notice of Bid Borrowing for a Fixed Rate Advance and by 1:30 p.m.
         (Montreal time) three (3) Business Days before the date of such
         proposed Bid Borrowing, in the case of a Notice of Bid Borrowing for a
         Libor Advance. In the event that the Administrative Agent does not
         receive a notice from a Lender making an offer for a Bid Advance by the
         applicable time set out above in this paragraph (ii), such Lender shall
         be deemed for all purposes to have elected not to make such an offer.
         The failure by any Lender to give such notice shall not cause such
         Lender to be obligated to make any Bid Advance as part of such proposed
         Bid Borrowing.

<PAGE>




                  (iii) The Borrower shall, in turn, (A) before 10:30 a.m.
         (Montreal time) on the date of such proposed Bid Borrowing, in the case
         of a Notice of Bid Borrowing for a Fixed Rate Advance and (B) before
         3:00 p.m. (Montreal time) three (3) Business Days before the date of
         such proposed Bid Borrowing, in the case of a Notice of Bid Borrowing
         for a Libor Advance, either:

                  (1) cancel such Bid Borrowing by giving the Administrative
                  Agent notice to that effect, or

                  (2) accept one or more of the offers made by any Lender or
                  Lenders pursuant to paragraph (ii) above, in its sole
                  discretion, by giving notice to the Administrative Agent of
                  the amount of each Bid Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the
                  Administrative Agent on behalf of such Lender for such Bid
                  Advance pursuant to paragraph (ii) above) to be made by each
                  Lender as part of such Bid Borrowing, and reject any remaining
                  offers made by Lenders pursuant to paragraph (ii) above by
                  giving the Administrative Agent notice to that effect.

         The acceptance of offers by the Borrower pursuant to clause (2) of this
         paragraph (iii) shall be on the basis of ascending rates of interest or
         margins contained in the offers made by the Lenders pursuant to
         paragraph (ii) above; provided that, in the event that two or more of
         such offers contain the same rate of interest or margin for a greater
         aggregate principal amount than the amount specified in such Notice of
         Bid Borrowing less the aggregate principal amount of all such offers
         containing lower rates of interest that have been accepted by the
         Borrower pursuant to clause (2) of this paragraph (iii), the Borrower
         shall accept such offers at such rate of interest or margin in amounts
         allocated among the Lenders which made such offers pro rata according
         to the amounts so offered (or as nearly pro rata as shall be
         practicable after giving effect to the requirement that Bid Advances
         made in connection with a Bid Borrowing shall be a minimum amount of
         C$1,000,000 for Bid Advances in C$ and a minimum amount of US$1,000,000
         for Bid Advances in US$).

                  (iv) If the Borrower notifies the Administrative Agent that
         such Bid Borrowing is cancelled pursuant to clause (1) of paragraph
         (iii) above, the Administrative Agent shall give prompt notice thereof
         to the Lenders and such Bid Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to clause (2) of paragraph (iii) above,
         the Administrative Agent shall in turn on the date of such acceptance
         notify (A) each Lender that has made an offer as described in paragraph
         (ii) above of the date and aggregate amount of such Bid Borrowing and
         whether or not any offer or offers made by such Lender pursuant to
         paragraph (ii) above have been accepted by the Borrower, (B) each




                                       45

         Lender that is to make a Bid Advance as part of such Bid Borrowing of
         the amount of each Bid Advance to be made by such Lender as part of
         such Bid Borrowing, and (C) each Lender that is to make a Bid Advance
         as part of such Bid Borrowing, upon receipt, that the Administrative
         Agent has received forms of documents appearing to fulfill the
         applicable conditions set forth in Article 10.

                  (vi) Each Lender that is to make a Bid Advance as part of such
         Bid Borrowing shall, before 12:00 noon (Montreal time) on the date of
         such Bid Borrowing specified in the notice received from the
         Administrative Agent pursuant to clause (B) of the preceding paragraph
         (v) or any later time when such Lender shall have received notice from
         the Administrative Agent pursuant to clause (C) of the preceding
         paragraph (v), make available for the account of its Applicable Lending
         Office such Lender's ratable portion of such Bid Borrowing by
         depositing such portion in same day funds in the Administrative Agent's
         account specified in Section 9.1. Upon fulfillment of the applicable
         conditions set forth in Article 10, the Administrative Agent will
         promptly make available to the Borrower at the Administrative Agent's
         aforesaid address such funds as shall have actually been received by
         the Administrative Agent. Promptly after each Bid Borrowing, the
         Administrative Agent will notify each Lender of the amount of the Bid
         Borrowing.

         3.4.2 Each Bid Borrowing shall be in an aggregate amount of not less
than C$10,000,000 or US$10,000,000 or an integral multiple of C$1,000,000 or
US$1,000,000 respectively in excess thereof. Following the making of each Bid
Borrowing (and the application of the proceeds thereof), the Borrower agrees
that it shall be in compliance with the limitations set forth in the proviso to
the first sentence of Section 3.4.1. Except as otherwise provided in this
Section 3.4, the provisions of this Agreement dealing with Libor Loans shall
apply, mutatis mutandis, to Bid Borrowings at margins relative to LIBOR.

         3.4.3 Within the limits and on the conditions set forth in this Section
3.4, the Borrower may from time to time borrow under this Section 3.4, repay or
prepay pursuant to Section 3.4.4, and re-borrow under this Section 3.4; provided
that a Bid Borrowing shall not be made within four Business Days of the date
that any other Bid Borrowing is made.

         3.4.4 The Borrower shall repay to the Administrative Agent for the
account of each Lender which has made a Bid Advance, on the maturity date of
each Bid Advance (such maturity date being that specified by the Borrower for
repayment of such Bid Advance in the related Notice of Bid Borrowing delivered
pursuant to Section 3.4.1(i)), the then unpaid principal amount of such Bid
Advance. The Borrower shall have no right to prepay any principal amount of any
Bid Advance except on the terms specified for prepayment by the Borrower for
such Bid Advance in the related Notice of Bid Borrowing delivered pursuant to
Section 3.4.1(i) or otherwise with the consent of the Lender that has made the
relevant Bid Advance.

         3.4.5 The Borrower shall pay interest on the unpaid principal amount of
each Bid Advance from the date of such Bid Advance to the date the principal
amount of such Bid Advance is repaid in full, at the rate of interest for such




                                       46

<PAGE>



Bid Advance specified by the Lender making such Bid Advance in its notice with
respect thereto delivered pursuant to Section 3.4.1(ii), payable on the interest
payment date or dates specified by the Borrower for such Bid Advance in the
related Notice of Bid Borrowing delivered pursuant to Section 3.4.1(i).

3.5      Money Market Loans

         3.5.1 The Borrower may at any time and from time to time request any
one or more of the Lenders to make offers to make Money Market Loans to the
Borrower on any Business Day during the period from the date hereof until the
Revolving Loan Commitment Termination Date in the manner set forth below. Each
such Lender may, but shall have no obligation to, make such offer, and the
Borrower may, but shall have no obligation to, accept any such offers in the
manner set forth in this Section 3.5.

         3.5.2 In the event that the Borrower desires to borrow a Money Market
Loan from a Lender, the Borrower shall, prior to 11:00 a.m. (Montreal time),
request that such Lender provide a quotation to the Borrower of the amount and
terms under which such Lender would be willing to provide such Money Market
Loan. Each Money Market Loan shall be in CDollars or USDollars and if in
CDollars, in an amount of not less than C$1,000,000 or on integral multiple of
C$1,000,000 in excess thereof, and if in USDollars, in an amount of not less
than US$1,000,000 or an integral multiple of US$1,000,000 in excess thereof.

         3.5.3 In the event that the Borrower elects to accept a Lender's offer
for a Money Market Loan, the Borrower shall provide telephonic notice to such
Lender of its election in a timely manner after the time that such offer was
received by the Borrower. The failure of the Borrower to provide such notice of
acceptance in a timely manner shall be deemed to constitute a rejection of the
offer of such Lender. Any Money Market Loan to be made by a Lender pursuant to
this Section 3.5 shall be made by the Lender crediting an account specified by
the Borrower with the amount of such advance in same day funds in accordance
with the terms agreed upon for such Money Market Loan following receipt of the
Borrower's timely acceptance of the offer of such Lender with respect to such
Money Market Loan.

         3.5.4 The Borrower agrees to forward to the Lender with respect to a
Money Market Loan written evidence of such Money Market Loan by providing, on
the date upon which such Money Market Loan is made, documents, in form and
substance acceptable to both the Borrower and such Lender, executed and
delivered by a duly authorized officer of the Borrower, confirming the amount so
borrowed, the rate of interest applicable thereto and the maturity thereof (with
such Money Market Loan being due and payable on such date of maturity); provided
that the failure of the Borrower to provide such documents shall not impair the
obligation of the Borrower to repay any Money Market Loan borrowed by it. All
borrowings pursuant to this Section 3.5 shall bear interest at the rate quoted
to the Borrower by the relevant Lender in its quotation described in Section
3.5.2.

         3.5.5 In the event that all amounts then owing under this Agreement
become due and payable prior to their scheduled maturity, each Lender that has a




                                       47

<PAGE>



Money Market Loan outstanding may declare its Money Market Loans (with any
applicable interest thereon) to be immediately due and payable without the
consent of, or notice to, any other Lender; provided that if such event is an
Event of Default specified in Section 12.1.11, each Lender's Money Market Loans
(and any applicable interest thereon) shall automatically become immediately due
and payable.

         3.5.6 The Borrower and any Lender may at any time and from time to time
enter into written agreements that provide for procedures for soliciting and
extending Money Market Loans that differ from those specified in Sections 3.5.2
to 3.5.5, inclusive. As between the Borrower and such Lender such agreements
shall supersede the provisions of such sections to the extent specified therein.

         3.5.7 In the event that the availability under any Lender's Revolving
Loan Commitment (after giving effect to any applicable Money Market Reduction)
has been reduced to a level that is insufficient to permit such Lender to lend
its ratable share of any Borrowing requested to be made hereunder, the Borrower
shall repay such Lender's outstanding Money Market Loans simultaneously with or
prior to such Borrowing (which repayment may be financed with proceeds of such
Advances and shall be subject to the provisions of Section 3.5.8) by the amount
necessary to increase the availability under its Revolving Loan Commitment
(before giving effect to such Borrowing, but after giving effect to the
application of the proceeds thereof and to any Money Market Reduction in effect
after such application) to be at least equal to its ratable share of any such
Borrowing.

         3.5.8 Notwithstanding anything to the contrary contained herein, the
following provision shall apply to all Money Market Loans unless expressly
otherwise excluded in the terms thereof. If any payment of principal of any
Money Market Loan is made other than on the maturity date of such Money Market
Loan, as a result of the acceleration of the maturity thereof pursuant to
Section 3.5.5 or for any other reason whatsoever, the Borrower shall, upon
demand by the applicable Lender (with a copy of such demand to the
Administrative Agent), pay directly to such Lender as it may direct any amounts
required to compensate such Lender for any losses, costs or expenses which it
may reasonably incur as a result of such payment, including, without limitation,
any loss, cost or expense incurred by reason of the liquidation or redeployment
of deposits or other funds acquired by such Lender to fund or maintain such
Money Market Loan.

         3.5.9 Notwithstanding anything to the contrary contained herein, Money
Market Loans shall be deemed not to be extensions of credit, Advances or
Borrowings under this Agreement; provided that Money Market Loans shall be
considered to be extensions of credit under this Agreement for purposes of
calculating the Money Market Reduction.

         3.5.10 Notwithstanding anything to the contrary contained herein, the
Administrative Agent shall have no responsibility whatsoever for Money Market
Loans, either before or after default hereunder or thereunder, including,
without limitation, for establishing the terms thereof, declaring defaults
thereunder, monitoring compliance by the Borrower therewith or verifying
payments or repayments thereunder, and to the extent that any Lender


                                       48

<PAGE>



entering into a Money Market Loan requires any additional documentation in
connection therewith, such documentation shall be entirely the responsibility of
such Lender, including without limitation the preparation, execution, delivery
and safe-keeping thereof.

         3.5.11 Unless the Borrower shall have previously given the
Administrative Agent written notice of all then outstanding (or committed to be
advanced on or prior to the Business Day of the proposed Borrowing) Money Market
Loans (which notice shall be in writing and shall specify the applicable Lender
which had advanced a Money Market Loan, the principal amount thereof and the
borrowing date and scheduled repayment date thereof), each Notice of Borrowing
or Notice of Bid Borrowing, as the case may be, given hereunder shall also
specify such information.

3.6      Notice Provisions

         3.6.1 For each Borrowing, each optional repayment and each conversion,
the Administrative Agent shall have received prior to 11:00 a.m (Montreal time)
from the Borrower in writing a Notice of Borrowing, a Notice of Optional
Repayment or a Notice of Conversion, as the case may be, in accordance with the
following:

         (a) at least one (1) Business Day prior to the Drawdown Date or
Conversion Date, as the case may be, for each Borrowing or conversion by way of
Canadian Rate Advance or Canadian Base Rate Advance;

         (b) at least two (2) Business Days prior to the Drawdown Date or
Conversion Date, as the case may be, for each Borrowing or conversion by way of
Acceptance;

         (c) at least three (3) Business Days prior to the Drawdown Date or
Conversion Date, as the case may be, for each Borrowing or conversion by way of
Libor Advance (provided, however, that with respect to Libor Advances to be made
on the Initial Funding Date, the Borrower shall be required to deliver the
relevant Notice of Borrowing no later than 9:00 a.m. (Montreal time) two (2)
Business Days prior to the Initial Funding Date); and

         (d) at least three (3) Business Days prior to the Optional Repayment
Date for each optional repayment.

         3.6.2 If the Borrower gives a Notice of Borrowing to the Administrative
Agent in accordance with Section 3.6.1, the Administrative Agent shall on the
same day it receives such Notice of Borrowing notify each Lender by telecopier
of the particulars of such request for a Borrowing and of such Lender's
Participation in the proposed Borrowing and each Lender shall, no later than
2:00 p.m. (Montreal time) on the Drawdown Date, make or procure to be made its
Participation in the Borrowing available to the Administrative Agent.




                                       49

3.7      Pro Rata Treatment

         Except in respect of Bid Loans, the Borrower agrees to request each
Borrowing from the Lenders pro rata in all respects according to their
respective Commitments and the Lenders agree to make each Borrowing available to
the Borrower pro rata in all respects according to their respective Commitments.
A Lender shall not be responsible for the Commitments of any other Lender.
Without prejudice to the rights of the Borrower against a defaulting Lender, the
failure or incapacity of a Lender to make available its Participation in a
Borrowing to the Borrower in accordance with its obligations under this
Agreement does not release the other Lenders from their obligations.

3.8      Accounts kept by the Administrative Agent

         The Administrative Agent shall keep in its books, accounts for the Loan
and other amounts payable by the Borrower under this Agreement. The
Administrative Agent shall keep appropriate registers showing, the amount of the
indebtedness of the Borrower in respect of the Loan and showing each payment or
repayment of principal and interest made in respect of such indebtedness. Such
registers shall constitute (in the absence of manifest error) prima facie
evidence of their content against the Borrower, the Guarantors and the Lenders;
provided that the obligation of the Borrower and the Guarantors to pay or repay
any indebtedness and liability in accordance with the terms and conditions of
this Agreement shall not be affected by the failure of the Administrative Agent
to keep such registers. The Administrative Agent shall supply any Lender and the
Borrower, on demand, with copies of such registers.

3.9      Accounts kept by each Lender

         Each Lender shall keep in its books, in respect of its Participation,
accounts for the Loan, any Bid Loans and Money Market Loans made by it, and
other amounts payable by the Borrower to it under this Agreement. Each Lender
shall make appropriate entries showing, as debits, the amount of the
indebtedness of the Borrower towards it in respect of the Loan, any such Bid
Loan or Money Market Loan, the amount of all accrued interest and any other
amount due to such Lender pursuant hereto and, as credits, each payment or
repayment of principal and interest made in respect of such indebtedness as well
as other amount paid to such Lender pursuant hereto. These accounts shall
constitute (in the absence of manifest error or of contradictory entries in the
accounts of the Administrative Agent referred in Section 3.8) prima facie
evidence of their content against the Borrower and the Guarantors.

                       REPAYMENT, CONVERSION AND REDUCTION

4.1      Mandatory Repayment and Prepayment of the Loan

         4.1.1 The Borrower covenants and agrees that it shall repay the Term
Loans made to it to the Administrative Agent for the account of the Lenders on
the Term Loan Maturity Date together with all unpaid interest accrued thereon or
owing pursuant thereto. The Borrower covenants and agrees that it shall repay
the Revolving Loans made to it to the Administrative Agent for the account of
the Lenders on the Revolving Loan Commitment Termination Date together with all
unpaid interest accrued and other amounts owing and unpaid hereunder or pursuant
hereto.

         4.1.2 Grand Trunk and the Borrower further covenant and agree that, no
later than the fifth Business Day following the date of receipt by the Borrower
or any of its Subsidiaries of any Net Asset Sale Proceeds in respect of any
Asset Sale consummated prior to the STB Approval Date, Grand Trunk and the
Borrower shall, and Grand Trunk shall cause each borrower under the US Credit
Agreement to, subject to Section 4.1.3, prepay the Term Loans, the Revolving
Loans, the US Term Loans and the US Revolving Loans in an aggregate amount equal
to such Net Asset Sale Proceeds (rounded downwards to the next lowest multiple
of US$100,000); provided, however, that Grand Trunk and the Borrower shall not
be required to repay (or to cause each borrower under the US Credit Agreement to
repay, as the case may be) any such Net Asset Sale Proceeds until the aggregate
amount thereof not yet applied to the repayment of the Term Loans, Revolving
Loans, US Term Loans and US Revolving Loans pursuant to Section 4.1.3 exceeds
US$10,000,000, at which time Grand Trunk and the Borrower shall be obligated to
repay (or to cause each borrower under the US Credit Agreement to repay, as the
case may be) all such Net Asset Sale Proceeds in accordance with this Section as
if the Borrower and its Subsidiaries had received such amounts at such time;
provided that, if the amount of any prepayment to the Term Loans or Revolving
Loans to be made by the Borrower pursuant to this Section 4.1.2 exceeds the
aggregate principal amount of that portion of the Term Loans or Revolving Loans,
respectively, bearing interest at a rate determined by reference to the Canadian
Rate or the Canadian Base Rate, the Borrower shall place and maintain with the
Administrative Agent a deposit in the amount of such excess amount pending
application of such amounts on deposit (it being understood that the Borrower,
other than upon the occurrence and during the continuance of an Event of
Default, may direct the Administrative Agent to invest such amounts on deposit
in cash equivalents) from time to time as soon as practicable thereafter to
repay Term Loans or Revolving Loans, respectively, consisting of new Canadian
Rate Loans or Canadian Base Rate Loans or other Advances to the Borrower, which
application shall be made in a manner which does not require additional payments
by the Borrower pursuant to Section 9.9.4.

         4.1.3 Any prepayments made pursuant to Section 4.1.2 shall be made
without premium or penalty and shall be applied first, to the prepayment of the
Term Loans and the US Term


                                       51

<PAGE>



Loans pro rata according to the respective outstanding principal amount, if any,
of each and to the full extent thereof, and second, to the prepayment of the
Revolving Loans and the US Revolving Loans pro rata according to the respective
outstanding principal amount, if any, of each and to the full extent thereof;
provided that prepayments of the Revolving Loans shall not be required pursuant
to Section 4.1.2 or this Section 4.1.3 if on the date the relevant Net Asset
Sale Proceeds are received by the Borrower or any of its Subsidiaries (i) the
Borrower's Public Debt Rating by S&P is BBB or higher or the Borrower's Public
Debt Rating by Moody's is Baa2 or higher and (ii) the aggregate Revolving Loan
Commitments and the commitments under the US Credit Agreement to make US
Revolving Loans are not greater than US$700,000,000.

4.2      Optional Repayments

         4.2.1 At any time prior to the Revolving Loan Commitment Termination
Date, subject to Section 4.4, the Borrower may elect to repay by a Notice of
Optional Repayment received by the Administrative Agent, and on the Optional
Repayment Date set forth therein the Borrower shall repay, to the Administrative
Agent for the account of the Lenders in CDollars or USDollars, as the case may
be, all or part of the Borrowings under the Credit with interest accrued thereon
to the date of such repayment. Within the limits of each Lender's Revolving Loan
Commitment and subject to the terms of this Agreement, the Borrower may reborrow
any Revolving Loans so repaid. Any optional repayments pursuant to this Section
4.2 shall be applied as specified by the Borrower in the applicable Notice of
Optional Prepayment; provided that in the event Borrower fails to specify the
Loans to which any such prepayment shall be applied, such prepayment shall be
applied first to repay outstanding Revolving Loans to the full extent thereof,
and applied pro rata in proportion to the amount of Revolving Loans made to the
Borrower, and second to repay outstanding Term Loans to the full extent thereof.
Notwithstanding anything in this Agreement to the contrary, the Borrower shall
not make any optional prepayment of all or a portion of the outstanding Term
Loans unless a ratable portion of the US Term Loans outstanding at the time of
such prepayment are also prepaid.

         4.2.2 Subject to compliance with Section 4.2.1, prepayments may be made
without premium or penalty.

         4.2.3 All optional repayments are in addition to and not in replacement
of mandatory repayments provided for in Section 4.1.1.

         4.2.4 Notwithstanding the foregoing, a Borrowing outstanding by way of
Letter of Credit may only be repaid or discharged prior to the expiry date of
the Letter of Credit by:

         (a) the Administrative Agent being fully released and discharged of all
         its liabilities and obligations arising from such Letter of Credit and
         by written evidence satisfactory to the Administrative Agent of such
         full release and discharge being delivered to the Administrative Agent;
         or




                                       52

<PAGE>



         (b) by way of the issue to the Administrative Agent by a financial
         institution acceptable to the Administrative Agent, in its sole
         discretion, of a full, unconditional counter-guarantee or indemnity in
         favor of the Administrative Agent acceptable to the Administrative
         Agent in respect of such Letter of Credit.

4.3      Conversion Option

         4.3.1 At any time prior to the Term Loan Maturity Date or the Revolving
Loan Commitment Termination Date, respectively, subject to Section 4.4, the
Borrower may elect to convert by Notice of Conversion received by the
Administrative Agent, and on the Conversion Date set forth therein the Borrower
shall convert, any basis of funding (other than Letters of Credit) of all or any
portion of the Borrowings consisting of Term Loans and/or the Borrowings
consisting of Revolving Loans, respectively (each a "Converted Advance"), into
another basis of funding (each a "Conversion Advance"); provided that (i) the
Borrower may convert the basis of funding of any Borrowings only into another
basis that the Borrower is permitted to select for such Borrowings under Section
3.1 or 3.2, and (ii) the Borrower may not elect to convert a Borrowing
denominated in CDollars to USDollars or a Borrowing denominated in USDollars to
CDollars. The provisions of this Agreement relating to Libor Advances shall
apply mutatis mutandis to Conversion Advances comprising Libor Advances. The
provisions of this Agreement relating to Acceptances shall apply mutatis
mutandis to Conversion Advances comprising Acceptances.

         4.3.2 If on any date an Advance is outstanding with respect to which
notice has not been delivered to the Administrative Agent specifying the
applicable basis for determining the rate of interest, then for that day that
Advance shall bear interest by reference to the Canadian Base Rate (in the case
of Advances to the Borrower other than Canadian Rate Advances) or the Canadian
Rate (in the case of Canadian Rate Advances).

4.4      Requirements for Optional Repayments and Optional Conversions

         Each optional repayment pursuant to Section 4.2 or conversion pursuant
to Section 4.3 shall be subject to the following terms and conditions:

         4.4.1 each repayment or conversion shall be in a minimum amount of
C$10,000,000 or US$10,000,000 or such larger amount as is an integral multiple
of C$1,000,000 or US$1,000,000 respectively (or, for repayments, the remaining
balance of the Borrowings if less than such minimum amount) in the currency of
the Borrowings or portion thereof to be repaid or of the Converted Advance, as
the case may be, and shall be made on a Business Day specified in the Notice of
Optional Repayment or Notice of Conversion;

         4.4.2 the Borrower shall have given the Administrative Agent notice in
accordance with Section 3.6 for each repayment and each conversion, each notice
stating the proposed date of the repayment or conversion and either the
aggregate principal amount of the repayment or the aggregate principal amount of
the Converted Advance and the type of Conversion Advance;


                                       53

<PAGE>




         4.4.3 if a Notice of Optional Repayment is given, it shall be
irrevocable and binding on the Borrower and the Borrower shall repay on the
Optional Repayment Date specified in such notice in CDollars or USDollars, as
the case may be, the amount stated in such notice with accrued interest to the
date of such repayment; and if a Notice of Conversion is given it shall be
irrevocable and binding on the Borrower; and

         4.4.4 should any such repayment or conversion result in the repayment
of or conversion from any Libor Loan Portion on a day other than the last day of
its then current Interest Period, the Borrower shall, in addition, pay to the
Administrative Agent the amount calculated as set forth in Section 9.9.4.

4.5      Excess Advances

         The Equivalent Amount in USDollars of the aggregate outstanding amount
of the Canadian Rate Loan, all Letters of Credit outstanding in CDollars, the
face amount of all Bankers' Acceptances and BA Equivalent Advances, all Bid
Advances or Money Market Loans outstanding in CDollars and any other Advances
outstanding in CDollars shall be determined by the Administrative Agent (i) on
each Drawdown Date, (ii) on each Conversion Date, (iii) on the last day of each
month, unless a Drawdown Date or Conversion Date occurs in such month and (iv)
at such other times as may be reasonably decided by the Administrative Agent. In
the event that on such date of determination the Equivalent Amount in USDollars
of the aggregate outstanding amount of the Canadian Rate Loan, all Letters of
Credit outstanding in CDollars, the face amount of all Bankers' Acceptances and
BA Equivalent Advances, all Bid Advances or Money Market Loans outstanding in
CDollars and any other Advances outstanding in CDollars plus the aggregate Libor
Loan, the aggregate Canadian Base Rate Loan, all Letters of Credit outstanding
in USDollars, all Bid Advances or Money Market Loans outstanding in USDollars
and all other Advances outstanding in USDollars, exceeds the then Total
Commitment of the Lenders (the "Excess"), then the Borrower shall within three
(3) days after notice of the amount of the Excess pay to the Administrative
Agent for application to repayment of Advances to the Borrower the amount of the
Excess in USDollars or the Equivalent Amount in CDollars; provided that nothing
in this Section 4.5 shall operate to postpone any payment due on the Term Loan
Maturity Date or the Revolving Loan Commitment Termination Date. Such payments
shall be applied on the date of receipt by the Administrative Agent to the
repayment of all outstanding Advances and Bid Advances and Money Market Loans;
provided, that if, on the date any such payment of an Excess is to be so
applied, the Equivalent Amount in USDollars of the aggregate Canadian Rate Loan
and the Canadian Base Rate Loan is less than the Excess, the Borrower shall
apply such Excess first, to the repayment of the Canadian Rate Loan and the
Canadian Base Rate Loan to the full extent thereof, and then place and maintain
with the Administrative Agent an interest bearing deposit in the amount of the
remainder. The Administrative Agent shall apply such amounts on deposit
(together with the interest accrued thereon) from time to time as soon as
practicable thereafter to repay any new Canadian Rate Loan or Canadian Base Rate
Loan or other Advances to the Borrower, which repayment shall be made in a
manner which does not require additional payments by the Borrower pursuant to
Section 9.9.4.






                                       54

4.6      Authority to Debit

         In respect of all amounts payable by the Borrower under this Agreement,
the Borrower hereby irrevocably authorizes and instructs the Administrative
Agent to withdraw from or debit, from time to time when such amounts are due and
payable, any account of the Borrower listed in Schedule 4.6 annexed hereto (as
such Schedule 4.6 may be amended from time to time as agreed between the
Borrower and the Administrative Agent) for the purpose of satisfying payment
thereof.

4.7      Reduction of the Commitments

         4.7.1 The Borrower may, upon at least five (5) Business Days' notice to
the Administrative Agent, terminate in whole or reduce ratably in part (without
premium or penalty) the unused portions of the Commitments of the Lenders;
provided that each partial reduction shall be in the aggregate amount of
US$25,000,000 or an integral multiple of US$5,000,000 in excess of
US$25,000,000. In any such notice, the Borrower must state the proposed date and
aggregate principal amount of the reduction and, if such notice is given, the
Borrower shall pay the Administrative Agent in accordance with such notice the
amount, if any, by which the Total Utilization of Revolving Loan Commitments
(after giving effect to any Money Market Reduction) exceeds the proposed reduced
aggregate Revolving Loan Commitments and the Borrower shall pay at the same time
all interest and other amounts owing in respect of such excess amount accrued to
the date of such reduction. Should any such payment result in the payment of any
Libor Loan Portion on a day other than the last day of its then current interest
period, the Borrower shall, in addition, pay to the Administrative Agent for the
benefit of the applicable Lenders the amount calculated as set forth in Section
9.9.4.

         4.7.2 On each date that the Revolving Loans are required to be prepaid
pursuant to Section 4.1.2, the Revolving Loan Commitments shall be permanently
reduced in the amount of such required prepayment.

4.8      Increase of Revolving Loan Commitment

         The Borrower may, from time to time, request an increase of each
Lender's Revolving Loan Commitment by giving written notice to the
Administrative Agent making such request and specifying the date upon which the
Borrower requests that such increase come into effect (the "Effective Date") and
detailing the amount by which each Lender's Revolving Loan Commitment shall be
increased; such notice shall be given by the Borrower between the 90th and 60th
days prior to the Effective Date. The Administrative Agent shall promptly
forward a copy of such request to the Lenders and each Lender shall notify the
Administrative Agent within 30 days of the Borrower's request whether such
Lender is willing to grant such an increase. In the event that a Lender has
failed to notify the Administrative Agent within such 30 day period of whether
it has elected to increase its Revolving Loan Commitment, such Lender shall be
deemed not to have elected to increase its Revolving Loan Commitment. Each
increase request shall be considered by each Lender, in its sole discretion, and




                                       55

<PAGE>



each Lender shall not, under any circumstances, be obliged to approve or accept
any increase request. The Administrative Agent shall promptly notify the
Borrower and the Lenders which Lenders have elected to increase their respective
Revolving Loan Commitments. In the event that a Lender elects to increase its
Revolving Loan Commitment then (regardless of whether any other Lender has
elected to so increase but provided there is no increase in the Total Commitment
unless all the Lenders and all lenders designated as "Lenders" under the US
Credit Agreement have agreed thereto) the Revolving Loan Commitment for such
Lender shall be increased by the amount of the increase requested by the
Borrower and agreed to by such Lender.

         If a Lender elects or is deemed to have elected not to increase its
Revolving Loan Commitment, the Lenders who have elected to increase their
Revolving Loan Commitments shall have the option (all such Lenders who elect to
exercise such option being "Accepting Lenders") to take up on a pro rata basis
the dissenting Lenders' portion of the increase by so advising the
Administrative Agent. The Administrative Agent shall allocate amongst the
Accepting Lenders the amount of the Revolving Loan Commitment available from
each dissenting Lender in its discretion but always on a pro rata basis or as
nearly pro rata as shall be practical.

         If the Accepting Lenders do not take up all of the dissenting Lenders'
portion of the increase (on a pro rata basis or otherwise), the Borrower may, at
its option (and at any time prior to or on the applicable Effective Date) offer
such portion to one or more financial institutions, provided that such other
financial institutions are acceptable to the Administrative Agent and provided
such offer is consummated as soon as possible to the satisfaction of the
Administrative Agent. The provisions in Section 15.14 dealing with Dissenting
Lenders shall not apply to a dissenting Lender under this Section 4.8


                                    ARTICLE 5

                                INTEREST AND FEES

5.1      Interest

         The Borrowings shall bear interest from the date of each Advance,
calculated on a daily basis and payable in arrears, on the Canadian Rate Loan at
the Canadian Rate, on the Canadian Base Rate Loan at the Canadian Base Rate, and
on each Libor Loan Portion at LIBOR plus the Applicable Margin in effect from
time to time for such Libor Loan Portion for the then current Interest Period,
and all overdue amounts shall bear interest in accordance with Section 5.6. All
outstanding amounts shall bear interest both before and after default and before
and after judgment at the rates determined as aforesaid.

5.2      Payment of Interest on Libor Loan

         On each Interest Payment Date in respect of each Libor Loan Portion of
a Lender, the Borrower shall pay the Administrative Agent interest on such Libor






                                       56

<PAGE>



Loan Portion at the rate per annum determined by the Administrative Agent to be
LIBOR in respect of such Libor Loan Portion for the applicable Interest Period
plus the Applicable Margin in effect from time to time during such Interest
Period. Upon determination of the applicable rate of interest on any Libor Loan
Portion, the Administrative Agent shall notify the Borrower of this rate. The
Administrative Agent will compute the interest on the basis of the actual number
of days elapsed in the period for which such interest is payable divided by
three hundred and sixty (360).

5.3      Payment of Interest on Canadian Rate Loan

         On each Interest Payment Date in respect of the Canadian Rate Loan, the
Borrower shall pay the Administrative Agent interest on the Canadian Rate Loan
at the Canadian Rate. The Borrower will pay this interest in arrears for the
period up to but excluding such Interest Payment Date; the Administrative Agent
will compute the interest on the basis of the actual number of days elapsed in
the period for which such interest is payable divided by the actual number of
days of the year. Each change in the fluctuating interest rate for the Canadian
Rate Loan will take place simultaneously with the corresponding change in the
Canadian Rate.

5.4      Payment of Interest on Canadian Base Rate Loan

         On each Interest Payment Date in respect of the Canadian Base Rate
Loan, the Borrower shall pay the Administrative Agent interest on the Canadian
Base Rate Loan at the Canadian Base Rate. The Borrower will pay this interest in
arrears for the period up to but excluding such Interest Payment Date; the
Administrative Agent will compute the interest on the basis of the actual number
of days elapsed in the period for which such interest is payable divided by the
actual number of days of the year. Each change in the fluctuating interest rate
for the Canadian Base Rate Loan will take place simultaneously with the
corresponding change in the Canadian Base Rate.

5.5      Selection of Interest Periods

         In each Notice of Borrowing delivered pursuant to Section 3.3 and each
Notice of Conversion delivered pursuant to Section 4.3 in which the Borrower has
elected a Borrowing or Conversion Advance comprising a Libor Loan Portion and at
least three Business Days prior to the last day of each Interest Period in
respect of each Libor Loan Portion, the Borrower shall select and notify the
Administrative Agent of the Interest Period applicable to such Libor Loan
Portion commencing on the Drawdown Date, Conversion Date or last day of the
Interest Period, as the case may be, and ending on a Business Day, which period
shall be one (1) month, two (2) months, three (3) months, six (6) months or,
subject to availability, nine (9) months or twelve (12) months, as the Borrower
may elect; provided, however, that:

         5.5.1 if the Borrower fails to so elect the duration of any Interest
Period, the amount of such Libor Loan Portion shall be deemed to be a Canadian
Base Rate Advance at the end of the current Interest Period and interest thereon
shall be payable at the Canadian Base Rate; and





                                       57

<PAGE>



         5.5.2 the amount in respect of which the Borrower selects an Interest
Period shall not be less than ten million USDollars (US$10,000,000) and in
integral multiples of one million USDollars (US$1,000,000) in excess thereof.

5.6      Default Interest

         If the Borrower defaults in any payment of principal, interest or any
other amount due pursuant to this Agreement, the Borrower shall pay to the
Administrative Agent on demand interest on such overdue principal, overdue
interest and other overdue amount, from the date the amount is due until the
date it is paid in full, and all interest on overdue principal, all overdue
interest and all interest on overdue interest shall be compounded monthly, at
the rates per annum as follows:

         5.6.1 with respect to the Libor Loan and any Libor Advance to the
Borrower, the Borrower shall be deemed to have elected that any amount of
principal of the Libor Loan or any Libor Loan Portion or Libor Advance which is
not paid when due shall thereupon cease to be a Libor Loan or Libor Advance and
shall be a Canadian Base Rate Advance, and the Borrower shall pay interest on
all such overdue principal and any overdue interest and interest on interest
thereon at a fluctuating rate per annum at all times equal to the Canadian Base
Rate plus two percent (2%) per annum; and

         5.6.2 on overdue principal of, and overdue interest on, the Canadian
Rate Loan and on any other amounts owing in CDollars, at a fluctuating rate per
annum at all times equal to the Canadian Rate plus two percent (2%) per annum.

5.7      Determination of Interest Rates

         5.7.1 Each Reference Lender, at the request of the Administrative
Agent, agrees to furnish to the Administrative Agent timely information for the
purpose of determining each Canadian Rate, each Acceptance Fee, each Canadian
Base Rate and each LIBOR. If any one or more of the Reference Lenders shall not
furnish such timely information to the Administrative Agent for the purpose of
determining any such interest rate or fee, the Administrative Agent shall
determine such interest rate or fee on the basis of timely information furnished
by the remaining Reference Lenders.

         5.7.2 Each determination by the Administrative Agent from time to time
of the Canadian Rate, the Canadian Base Rate, LIBOR, the Applicable Margin and
the Acceptance Fee shall, in the absence of manifest error, be final, conclusive
and binding upon the Borrower, the Guarantors and the Lenders.

5.8      Acceptance Fee

         If the Borrower notifies the Administrative Agent pursuant to Section
3.6 that a Borrowing is to be made by way of Bankers' Acceptances (or, as the



                                       58

<PAGE>



case may be, BA Equivalent Advances), the Borrower shall pay in CDollars at or
prior to the time of the Acceptance of each Bankers' Acceptance an Acceptance
Fee on the face value of each Bankers' Acceptance accepted by a Lender. The
Acceptance Fee shall be computed on the basis of the actual number of days of
the Bankers' Acceptance divided by the actual number of days of the year.

5.9      Underwriting Fee

         The Borrower shall pay to the Arrangers, for their own accounts, the
underwriting fees set forth in that certain letter agreement between the
Borrower and the Arrangers dated February 9, 1998, to the extent not paid prior
to the date hereof.

5.10     Facility Fee

         The Borrower shall pay to the Administrative Agent, for the account of
each Lender, a facility fee from the Closing Date until the Revolving Loan
Commitment Termination Date on the sum of the amount of such Lender's Revolving
Loan Commitment (whether used or unused) and (x) until the Initial Funding Date,
such Lender's Term Loan Commitment and (y) on and after the Initial Funding
Date, the principal amount of such Lender's outstanding Term Loan at the rate
equal to the Facility Fee in effect from time to time during the period for
which such payment is made, payable in arrears on the last day of each March,
June, September and December, commencing on the first such day to occur after
the Closing Date and on the Revolving Loan Commitment Termination Date. The
Facility Fee shall accrue from day to day and be calculated on the basis of a
year of 365 (or 366 in a leap year) days for the actual number of days elapsed.
Under no circumstances shall such Facility Fee be refundable either in whole or
in part, even if no Advance is ever made under the terms hereof.

5.11     Administrative Fee

         The Borrower shall pay to the Administrative Agent, for its account
exclusively, an annual administrative fee as agreed between the Borrower and the
Administrative Agent in a letter agreement dated February 6, 1998.

5.12     Certain Computations

         5.12.1 All computations of interest shall be made by the Administrative
Agent taking into account the actual number of days occurring in the period for
which such interest is payable, and (i) with respect to the Canadian Rate or the
Canadian Base Rate, on the basis of a year of 365 or 366 days, as the case may
be, or (ii) with respect to LIBOR or any interest accruing on a Fixed Rate
Advance, on the basis of a year of 360 days.

         5.12.2 For purposes of the Interest Act (Canada), (i) whenever any
interest or Fee under this Agreement is calculated using a rate based on a year
of 360 days, such rate determined pursuant to such calculation, when expressed




                                       59

<PAGE>



as an annual rate, is equivalent to (x) the applicable rate based on a year of
360 days, (y) multiplied by the actual number of days in the calendar year in
which the period for which such interest or fee is payable (or compounded) ends,
and (z) divided by 360, (ii) the principle of deemed reinvestment of interest
does not apply to any interest calculation under this Agreement, and (iii) the
rates of interest stipulated in this Agreement are intended to be nominal rates
and not effective rates or yields.

6.1      Bankers' Acceptances

         Subject to the terms and conditions hereof, upon giving to the
Administrative Agent prior written notice in accordance with Section 3.6 hereof
by means of a Notice of Borrowing, on any Business Day the Borrower may borrow
from the Lenders up to the amount of the Available Revolving Loan Commitment by
way of Acceptances, provided that:

         6.1.1 each Bankers' Acceptance is denominated in CDollars and the
minimum aggregate amount of each Borrowing by way of Bankers' Acceptances shall
be ten million CDollars (C$10,000,000) or in integral multiples of one million
CDollars (C$1,000,000) in excess of such minimum aggregate amount;

         6.1.2 each Lender shall have received a Bankers' Acceptance or Bankers'
Acceptances in the aggregate principal amount of such Borrowing from such Lender
in due and proper form duly completed and executed by the Borrower and presented
for acceptance to such Lender prior to 10:00 a.m. (Montreal time) on the
Drawdown Date, together with such other document or documents as such Lender may
reasonably require (including the execution by the Borrower of such Lender's
usual form of Bankers' Acceptances) and the Acceptance Fee shall have been paid
to such Lender at or prior to such time;

         6.1.3 each Bankers' Acceptance shall be stated to mature on a Business
Day, no later than the Revolving Loan Commitment Termination Date, which is
approximately thirty (30), sixty (60), ninety (90) or one hundred and eighty
(180) days or, subject to availability, periods in excess of 180 days from the
date of its acceptance;

         6.1.4 each Bankers' Acceptance shall be stated to mature on a Business
Day in such a way that no Lender will be required to incur any costs for the
redeployment of funds as a consequence of a mandatory repayment under Section
4.1.1 during any period for which such Bankers' Acceptance is outstanding;

         6.1.5 no days of grace shall be permitted on any Bankers' Acceptance;






                                       60

<PAGE>



         6.1.6 the aggregate face amount of the Bankers' Acceptances to be
accepted by a Lender shall be determined by the Administrative Agent by
reference to the respective Revolving Loan Commitments of the Lenders, except
that, if the face amount of a Bankers' Acceptance which would otherwise be
accepted by a Lender would not be C$100,000 or a whole multiple thereof, such
face amount shall be increased or reduced by the Administrative Agent in its
sole discretion to C$100,000 or the nearest whole multiple of that amount, as
appropriate.

6.2      Payments at Maturity

         By no later than 10:00 a.m. (Montreal time) on the maturity date of
each Bankers' Acceptance, the Borrower shall pay to the Administrative Agent for
the account of each Lender an amount equal to the face value of each Bankers'
Acceptance accepted by such Lender maturing on that day (notwithstanding that a
Lender may be the holder thereof at maturity). If for any reason the Borrower
fails to make such payment in respect of any Bankers' Acceptance, the Borrower
shall be deemed for all purposes to have received on the maturity date of each
such Bankers' Acceptance a Canadian Rate Advance in an amount equal to the face
value of each such Bankers' Acceptance and the Borrower shall pay interest
thereon at the Canadian Rate until repayment thereof in full by the Borrower,
the whole notwithstanding the fact that any Bankers' Acceptances may be held by
a Lender in its own right at maturity. The Borrower and each of the Guarantors
acknowledge, agree and confirm with the Lenders that the records of each Lender
in respect of payment of any Bankers' Acceptance by such Lender shall be binding
on the Borrower and the Guarantors and shall be conclusive evidence (in the
absence of manifest error) of a Canadian Rate Advance to the Borrower and of an
amount owing by the Borrower to such Lender. The Borrower further agrees that if
an Event of Default shall occur prior to the date upon which any one or more
Bankers' Acceptances are payable by a Lender, thereupon, the Borrower shall
provide such Lender with funds for the full face amount of all such Bankers'
Acceptances, notwithstanding the fact that any such Bankers' Acceptance may be
held by such Lender in its own right at maturity; provided, however, that if for
any reason the Borrower fails to make such payment in respect of any Bankers'
Acceptance, thereupon the Borrower shall be deemed for all purposes to have
received a Canadian Rate Advance in an amount equal to the face amount of such
Bankers' Acceptance and the Borrower shall pay interest thereon at the Canadian
Rate until repayment thereof in full.

6.3      BA Equivalent Advances

         In the event a Lender is unable to accept Bankers' Acceptances other
than under the circumstances set forth in Section 6.4, such Lender shall have
the right at the time of accepting drafts to require the Borrower to accept an
Advance in CDollars from such Lender in lieu of the issue and acceptance of a
Bankers' Acceptance requested by the Borrower to be accepted so that there shall
be outstanding while the Bankers' Acceptances are outstanding BA Equivalent
Advances from such Lender as contemplated herein. The principal amount of each
BA Equivalent Advance shall be that amount which, when added to the face amount
of interest (calculated at the applicable Discount Rate) which will accrue
during the BA Equivalent Interest Period shall be equal, at maturity, to the





                                       61

<PAGE>



face amount of the drafts which would have been accepted by such Lender had it
accepted Bankers' Acceptances. The "BA Equivalent Interest Period" for each BA
Equivalent Advance shall be equal to the term of the drafts presented for
acceptance as Bankers' Acceptances on the relevant Drawdown Date.

         On the relevant Drawdown Date the Borrower shall pay to the
Administrative Agent a fee equal to the Acceptance Fee which would have been
payable to such Lender if it were a Lender accepting drafts having a term to
maturity equal to the applicable BA Equivalent Interest Period and an aggregate
face amount equal to the sum of the principal amount of the BA Equivalent
Advance and the interest payable thereon by the Borrower for the Applicable BA
Equivalent Interest Period.

         The provisions of this Agreement dealing with Bankers' Acceptances
shall apply, mutatis mutandis, to BA Equivalent Advances.

6.4      Circumstances Making Bankers' Acceptances Unavailable

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

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

         (b) any Notice of Borrowing by way of Bankers' Acceptance which is
         outstanding shall be cancelled and the Advance therein shall not be
         made; and

         (c) the Administrative Agent shall promptly notify the Borrower of the
         suspension of the Borrower's right to request a Borrowing by way of
         Bankers' Acceptance and of the termination of any such suspension.

6.5      Purchase of Bankers' Acceptances

         Each Bankers' Acceptance issued pursuant to this Agreement shall be
purchased by the Lender accepting such Bankers' Acceptance for the Discounted
Proceeds thereof. In each case, upon receipt of such Discounted Proceeds from
the Lenders and upon fulfillment of the applicable conditions set forth in
Article 10, the Administrative Agent shall make such funds available to the
Borrower in accordance with this Agreement.

         Upon each issue of Bankers' Acceptances as a result of the conversion
of outstanding Borrowings into Bankers' Acceptances, the Borrower shall,
concurrently with the conversion, pay in advance to the Administrative Agent on
behalf of the Lenders, the amount by which the face value of such Bankers'
Acceptances exceeds the Discounted Proceeds of such Bankers' Acceptances, to be
applied against the principal amount of the Borrowing being so converted.





                                       62

<PAGE>



The Borrower shall at the same time pay to the Administrative Agent for
distribution to the applicable Lenders the applicable Acceptance Fee.

         The Borrower acknowledges and agrees that each Lender may, at any time,
arrange for its Participant or Assignee to accept and purchase Bankers'
Acceptances hereunder. Any such acceptance by a Participant or Assignee shall be
deemed to be an Acceptance by such Lender for the purposes of this Agreement.

6.6      Pre-Signed Draft Forms

         To enable the Lenders to make Advances in the manner specified in this
Article 6, the Borrower shall, in accordance with the request of each Lender
either (i) provide a power of attorney to complete, sign, endorse and issue
Bankers' Acceptances, in substantially the form of Schedule 6.6 annexed hereto,
or such other form as such Lender may reasonably require; or (ii) supply each
Lender with such number of drafts as such Lender may reasonably request, duly
endorsed and executed on behalf of the Borrower. Each Lender shall exercise such
care in the custody and safekeeping of drafts as it would exercise in the
custody and safekeeping of similar property owned by it. Each Lender will, upon
request by the Borrower, promptly advise the Borrower of the number and
designations, if any, of the uncompleted drafts then held by it.


                                    ARTICLE 7

                                LETTERS OF CREDIT

7.1      Letter of Credit Commitment

         Subject to the terms and conditions hereof, the Administrative Agent,
on behalf of the Lenders, and in reliance on the agreements of the Lenders set
forth in Section 7.2, agrees to issue for the account of the Borrower Letters of
Credit in CDollars or USDollars from time to time on any Business Day during the
period from the date hereof until the date occurring one month prior to the
Revolving Loan Commitment Termination Date; provided that (a) the Letter of
Credit Exposure shall not at any time exceed US$120,000,000, (b) the Borrower
shall not request the issuance of any Letter of Credit if, after giving effect
to such issuance, the Total Utilization of Revolving Loan Commitments (after
giving effect to any Money Market Reduction) would exceed the aggregate
Revolving Loan Commitments and (c) the Borrower shall not request the issuance
of, and the Administrative Agent shall not issue, any Letter of Credit having an
expiration date later than the Revolving Loan Commitment Termination Date.

7.2      Letter of Credit Participations

         The Administrative Agent irrevocably grants, and in order to induce the
Administrative Agent to issue its Letters of Credit for the account of the
Borrower hereunder, each Lender irrevocably accepts and hereby purchases from





                                       63

<PAGE>



the Administrative Agent, on the terms and conditions hereinafter stated, for
its own account and risk an undivided interest equal to such Lender's
Participation in the Administrative Agent's obligations and rights under each
Letter of Credit issued hereunder for the account of the Borrower and the amount
of each draft paid by the Administrative Agent thereunder. Each Lender
unconditionally and irrevocably agrees with the Administrative Agent that, on or
before the close of business of the Administrative Agent, on each day on which a
draft is paid under a Letter of Credit issued for the account of the Borrower
for which the Administrative Agent is not reimbursed in full by the Borrower in
accordance with the terms of this Agreement, including, without limitation,
pursuant to Section 7.8.1 (a "Lender Participation Date"), such Lender will pay
to the Administrative Agent for the account of the Administrative Agent at the
Administrative Agent's office specified in Section 9.1 such Lender's
Participation of any unpaid Reimbursement Obligation. The Administrative Agent
shall notify each Lender of the occurrence of a Lender Participation Date, and
the amount payable by it to the Administrative Agent based on such Lender's
Participation. Any such notice may be oral if promptly confirmed in writing
(including telecopy). If any Lender fails to make any such payment on or prior
to the first Business Day after such Lender receives notice as provided above,
then interest shall accrue on such Lender's obligation to make such payment
during the period from such Business Day to the day such Lender makes such
payment (or if earlier, the date on which the Borrower reimburses the
Administrative Agent for such unpaid Reimbursement Obligation) at the rate
specified in Section 15.6.2.

7.3      Repayment of Participants

         Upon and only upon receipt by the Administrative Agent of funds from
the Borrower in full or partial reimbursement of any draft paid under a Letter
of Credit with respect to which any Lender has theretofore paid the
Administrative Agent for the account of the Administrative Agent in full for
such Lender's participation pursuant to Section 7.2 and in full or partial
payment of interest, commissions or fees on such draft paid under a Letter of
Credit, the Administrative Agent will pay to such Lender, in the same funds as
those received by the Administrative Agent, or net against any then due
obligation of such Lender under Section 7.2 to make any payment to the
Administrative Agent, such Lender's Participation of such funds.

7.4      Role of the Administrative Agent

         The Administrative Agent will exercise and give the same care and
attention to each Letter of Credit as it gives to its other letters of credit
and similar obligations, and the Administrative Agent's sole liability to each
Lender shall be to distribute promptly, as and when received by the
Administrative Agent, each Lender's Participation of any payments made to the
Administrative Agent by the Borrower pursuant to Section 7.2. Each Lender agrees
that, in paying any drawing under a Letter of Credit, the Administrative Agent
shall not have any responsibility to obtain any document (other than as required
by such Letter of Credit) or to ascertain or inquire as to the validity or
accuracy of any such document or the authority of any Person delivering any such
document. Neither the Administrative Agent nor any of its representatives,
officers, employees or agents shall be liable to any Lender for (a) any action
taken or omitted to be taken in connection herewith at the request or with the





                                       64

<PAGE>



approval of the Majority Lenders, (b) any action taken or omitted to be taken in
the absence of gross negligence or wilful misconduct, (c) any recitals,
statements, representations or warranties contained in any document distributed
to any Lender, (d) the creditworthiness of the Borrower, or (e) the execution,
effectiveness, genuineness, validity, or enforceability of any Letter of Credit,
or any other document contemplated thereby. The Administrative Agent shall not
incur any liability (i) by acting in reliance upon any notice, consent,
certificate, statement or other writing (which may be a bank wire, telex or
similar writing) believed by it to be genuine or to be signed by the proper
party or parties or (ii) by acting as permitted under Section 7.14. The
obligations of the Lenders hereunder are several, and no Lender shall be liable
for the performance or non-performance of the obligations of any other Lender
under this Article 7.

7.5      Lenders' Obligations Absolute

         Each Lender acknowledges that its obligations to the Administrative
Agent under this Article 7, including the obligation to purchase and fund a
participation in the obligations and rights of the Administrative Agent under
each Letter of Credit and any unpaid Reimbursement Obligation, is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including, without limitation, (i) the occurrence and continuance of an Event of
Default or an event which, with the giving of notice or the passage of time, or
both, would constitute an Event of Default, (ii) subject to the next sentence of
this Section 7.5, the fact that a condition precedent to the issuance of any
Letter of Credit was not in fact satisfied, (iii) any failure or inability of
any other Lender to purchase or fund such a participation hereunder, or (iv) any
other failure by any other Lender to fulfil its obligations hereunder. Without
affecting the rights and remedies of the Administrative Agent and the Lenders
with respect to the Borrower in the event of any such condition precedent is not
in fact satisfied, each Lender authorizes the Administrative Agent in its sole
discretion and on behalf of such Lender (but without obligating the
Administrative Agent), without further notice to such Lender so long as the
Administrative Agent shall have notified the Lenders two Business Days prior to
the day of issuance that such condition precedent is not or will not be
satisfied, to waive any condition precedent set forth in Article 10 to the
issuance of the Letter of Credit (or deem each such condition precedent
satisfied) in connection with each issuance of the Letters of Credit unless the
Administrative Agent shall have received by the close of its business, Montreal
time, on the Business Day immediately preceding the day of such issuance written
instructions from the Majority Lenders not to waive such condition precedent and
such written instructions have not been withdrawn by the Majority Lenders. Each
payment by a Lender to the Administrative Agent for its own account shall be
made, without any offset, compensation, abatement, withholding or reduction
whatsoever.

7.6      Reinstatement and Survival

         Notwithstanding anything herein to the contrary, if the Administrative
Agent is required at any time whether before or after the Revolving Loan
Commitment Termination Date to make any payment under a Letter of Credit which
was outstanding on or before the Revolving Loan Commitment Termination Date,





                                       65

<PAGE>



each Lender shall pay over to the Administrative Agent, in accordance with the
provisions of this Article 7, the amount of such Lender's Participation of such
amount. If the Administrative Agent is required at any time (whether before or
after the Revolving Loan Commitment Termination Date) to return to the Borrower
or to a trustee, receiver, liquidator, custodian or other similar official any
portion of the payments made by or on behalf of the Borrower to the
Administrative Agent in reimbursement of Reimbursement Obligations and interest
thereon, each Lender shall, on demand of the Administrative Agent, forthwith pay
over to the Administrative Agent for its account such Lender's Participation of
such amount, plus interest thereon from the day such demand is made to the day
such amount is returned by such Lender to the Administrative Agent at the rate
specified in Section 15.6.2.

7.7      Procedure for Issuance and Renewal of Letters of Credit

         7.7.1 The Borrower may request the Administrative Agent to issue a
Commercial Letter of Credit in favor of a seller of goods to the Borrower, by
delivering to the Administrative Agent at its office specified in Section 9.1 a
commercial letter of credit application on the Administrative Agent's then
customary form (as such form may be modified from time to time, the "Commercial
Letter of Credit Applications"), completed to the satisfaction of the
Administrative Agent, together with the proposed form of such Commercial Letter
of Credit (which shall comply with the applicable requirements set forth herein)
and such other certificates, documents and other papers and information as the
Administrative Agent may reasonably request; provided that in the event of a
conflict between this Agreement and the Commercial Lever of Credit Application,
this Agreement shall govern with respect to such conflict.

         7.7.2 The Borrower may request the Administrative Agent to issue a
Standby Letter of Credit by delivering to the Administrative Agent at its office
specified in Section 9.1 a standby letter of credit application on the
Administrative Agent's then customary form (as such form may be modified from
time to time, the "Standby Letter of Credit Application"), completed to the
satisfaction of the Administrative Agent, together with the proposed form of
such Standby Letter of Credit (which shall comply with the applicable
requirements set forth herein) and such other certificates, documents and other
papers and information as the Administrative Agent may reasonably request;
provided that in the event of a conflict between this Agreement and the Standby
Letter of Credit Application, this Agreement shall govern with respect to such
conflict.

         7.7.3 Within three (3) Business Days following the date on which the
Administrative Agent shall have received an application for the issuance of a
Letter of Credit including the form thereof, and such additional certificates,
documents and other papers and information as the Administrative Agent may have
reasonably requested in satisfaction of all conditions to the issuance thereof,
the Administrative Agent shall, provided the conditions of Article 10 have been
complied with, issue such Letter of Credit (if the Borrower shall have requested
that such Letter of Credit be issued immediately) or (if the Borrower shall have
requested in the related Commercial Letter of Credit Application or Standby
Letter of Credit Application that such Letter of Credit be issued at a later
date) the Administrative Agent shall notify the Borrower that the Administrative
Agent shall, provided the conditions of Article 10 have been complied with,





                                       66

<PAGE>



issue such Letter of Credit on such later date, or that the Administrative Agent
shall not issue such Letter of Credit by reason of a provision set forth herein.

         7.7.4 The Borrower may request the extension or renewal of a Letter of
Credit issued hereunder which is not automatically renewed in accordance with
the terms contained therein, by giving written notice to the Administrative
Agent at least three (3) Business Days prior to the then current expiry date of
such Letter of Credit (provided that the Administrative Agent may accommodate
notices on shorter notice in its sole discretion). If the conditions precedent
in Section 10.2 shall have been fulfilled as required thereby, the
Administrative Agent shall promptly issue such extension or renewal.

         7.7.5 With respect to any Letter of Credit issued hereunder which by
its terms is automatically renewed or extended unless notice to the contrary is
received by the beneficiary thereunder within the time period set forth therein
(the "Revocation Period"), the Administrative Agent shall, upon receipt of
notice from the Majority Lenders (which notice must be received by the
Administrative Agent not later than 10:00 A.M. (Montreal time) ten (10) Business
Days prior to the expiration of the Revocation Period so long as the
Administrative Agent shall have notified the Lenders of such renewal or
extension at least one Business Day prior to such date), to the effect that the
Majority Lenders have elected not to extend the current expiry date of such
Letter of Credit, promptly notify the Borrower and the beneficiary thereunder
that such Letter of Credit shall not be renewed.

         7.7.6 Notwithstanding anything to the contrary in this Agreement, the
Administrative Agent shall have no obligation to extend or renew any Letter of
Credit issued hereunder to a maturity date extending beyond the Revolving Loan
Commitment Termination Date, and each Lender shall have no obligation to
purchase a participation in the Administrative Agent's obligations and rights
under any Letter of Credit extended or renewed to a date beyond the Revolving
Loan Commitment Termination Date.

7.8      Reimbursement of the Administrative Agent

         7.8.1 In the event that any drawing shall be made under any Letter of
Credit, and if no Event of Default shall have occurred and be continuing, (i)
the Administrative Agent shall promptly notify the Borrower of such payment and
of the amount thereof, (ii) the payment by the Administrative Agent of such
drawing shall, if the Letter of Credit was in CDollars, constitute the making of
a Canadian Rate Advance to the Borrower by the Lenders according to their
respective Participation, and the Borrower shall be deemed to have elected to
denominate same in CDollars and pay interest thereon at the Canadian Rate, (iii)
the payment by the Administrative Agent of such drawing shall, if the Letter of
Credit was in USDollars, constitute the making of a Canadian Base Rate Advance
to the Borrower by the Lenders according to their respective Participation and
the Borrower shall be deemed to have elected to denominate same in USDollars and
pay interest thereon at the Canadian Base Rate, (iv) the Administrative Agent
shall notify each Lender by telecopier or by telephone (confirmed by telecopier)
of such drawing and of the portion thereof constituting a Canadian Rate Advance



                                       67

<PAGE>



and of the portion thereof constituting a Canadian Base Rate Advance and (v)
immediately upon receipt of such notice, each Lender shall make its
Participation, in CDollars or USDollars, as applicable, available to the
Administrative Agent by wire transfer of immediately available funds to the
office of the Administrative Agent specified in Section 9.1.

         7.8.2 In the event that a drawing shall be made under any Letter of
Credit and an Event of Default shall have occurred, no Canadian Rate Advance or
Canadian Base Rate Advance shall be deemed to have been made in respect of such
drawing and the Borrower (i) shall reimburse the Administrative Agent for the
amount paid on each draft drawn under each Letter of Credit not later than the
close of business on the first Business Day following the day on which the
Borrower receives notice of such drawing, and (ii) shall pay, (A) all charges
and expenses relating to such drawing as may be payable in accordance with
Section 7.9 and (B) interest at the rate specified in Section 7.10 on the amount
of such drawing for the period commencing on the date of any such payment and
ending on the date reimbursement is received by the Administrative Agent.

7.9      Commissions, Fees and Charges

         7.9.1 The Borrower agrees to pay for each Letter of Credit, to (A) the
Administrative Agent (solely for its account) a non-refundable fronting fee with
respect to each Letter of Credit, in an amount equal to 1/8 of 1% per annum of
the face amount thereof, and (B) the Administrative Agent for the account of
each Lender, a non-refundable letter of credit commission, computed at a rate
equal to the Applicable Margin times such Lender's Participation of the
aggregate amount available to be drawn under such Letter of Credit, such
fronting fee and letter of credit commissions to be payable quarterly in advance
for the number of days outstanding, at the rate specified above and in the
currency of such Letter of Credit, commencing on the date of issuance of such
Letter of Credit and thereafter on the last day of each March, June, September
and December so long as such Letter of Credit shall remain outstanding.

         7.9.2 In addition to the fees referred to in Section 7.9.1, the
Borrower agrees to pay or reimburse the Administrative Agent for such normal and
customary costs and expenses as are incurred or charged by the Administrative
Agent in issuing, effecting payment under or administering any Letter of Credit
(including, without limitation, amendment fees, correspondent lender fees,
reissuance costs and cancellation fees).

         7.9.3 The Administrative Agent shall promptly distribute, at the end of
each calendar quarter, all letter of credit commissions received for the account
of each Lender by the Administrative Agent during such calendar quarter,
together with a statement from the Administrative Agent reconciling the
collection and distribution of such commissions.




                                       68

<PAGE>



7.10     Interest on Amounts Disbursed under Letters of Credit

         Subject to Section 7.8, the Borrower agrees to pay to the
Administrative Agent interest on any and all amounts disbursed by the
Administrative Agent under any Letter of Credit from the date of disbursement
until reimbursed in full at the Canadian Rate for Letters of Credit in CDollars
and at the Canadian Base Rate for Letters of Credit in USDollars. Interest
accrued hereunder shall be payable on demand. For the purposes of computing the
number of days for which interest shall accrue on amounts disbursed under
Letters of Credit, payments received by the Administrative Agent after 1:00 PM.,
Montreal time, shall be deemed to have been received on the next following
Business Day. All payments (including prepayments) by the Borrower to the
Administrative Agent, whether on account of the Borrower's Reimbursement
Obligation or interest thereon, on account of any fees due hereunder or
otherwise, shall be made in CDollars for Letters of Credit in CDollars and in
USDollars for Letters of Credit in USDollars and in immediately available funds
without set off, compensation or counterclaim to the Administrative Agent.

7.11     Computation of Interest and Fees; Payment not on Business Day

         7.11.1 Interest and per annum fees due under this Article 7 shall be
computed on the basis of a year of 365 (or 366 in a leap year) days for actual
days elapsed. Any change in any interest rate hereunder resulting from a change
in the Canadian Rate or the Canadian Base Rate, shall become effective as of the
opening of business on the day on which such change in the Canadian Rate or the
Canadian Base Rate becomes effective.

         7.11.2 If any payment under this Article 7 becomes due and payable on a
day which is not a Business Day, the maturity thereof shall be extended to the
next succeeding Business Day, and, in the case of any amount disbursed under a
Letter of Credit, interest thereon shall be payable at the then applicable rate
during such extension.

7.12     Increased Costs

         If any change occurring after the date of this Agreement in any Law or
in the interpretation or application thereof by any Governmental Authority
charged with the administration thereof shall either (i) impose, modify, assess
or deem applicable any reserve, special deposit, assessment or similar
requirement against Letters of Credit issued by the Administrative Agent or any
Lender or (ii) impose on the Administrative Agent or any Lender any other
condition regarding any Letter of Credit, and the result of any event referred
to in clauses (i) or (ii) above shall be to increase the cost to the
Administrative Agent or such Lender of issuing or maintaining a Letter of
Credit, or its participation therein, as the case may be (which increase in cost
shall be the result of the Administrative Agent's or such Lender's reasonable
allocation of the aggregate of such cost increases resulting from such events),
then, upon demand by the Administrative Agent or such Lender, the Borrower shall
immediately pay to the Administrative Agent or such Lender, from time to time as
specified by the Administrative Agent or such Lender, additional amounts which



                                       69

<PAGE>



shall be sufficient to compensate the Administrative Agent or such Lender for
such increased cost, together with interest on each such amount from the date
demanded until payment in full thereof at the rate provided in Section 7.10. A
certificate as to the fact and amount of such increased cost incurred by the
Administrative Agent or any Lender as a result of any event mentioned in clauses
(i) or (ii) above, submitted by the Administrative Agent or any such Lender to
the Borrower, shall be conclusive, absent manifest error.

         In the event the Borrower is required to pay additional amounts as
compensation for increased cost as provided above, the Borrower shall (subject
to the terms hereof) be entitled to require (with a copy to the Administrative
Agent) the Lender to whom such additional amounts are being paid to assign to an
alternate lender in accordance with Section 16.1.7 all of such Lender's rights
and obligations hereunder and such alternate lender shall execute all such
documents as may be reasonably required by the Administrative Agent, the
Borrower and such Lender to effect such assignment provided that (i) each such
assignment shall be arranged by the Borrower (with such reasonable assistance
from such Lender as the Borrower may request) after consultation with the
Administrative Agent and shall be an assignment of all of the rights and
obligations of the assigning Lender under this Agreement, (ii) no Lender shall
be obligated to make any such assignment as a result of a demand by the Borrower
pursuant to this Section 7.12 unless and until such Lender shall have received
payment from either the Borrower or the assignee in an aggregate amount at least
equal to the aggregate outstanding principal amount of the Loan and Bid Loan and
any Money Market Loans owing to such Lender, together with accrued interest
thereon to the date of payment of such principal amount and all other amounts
payable to such Lender under this Agreement (including, without limitation,
payment of the increased costs and additional amounts demanded by such Lender
pursuant to this Section 7.12 incurred by such Lender prior to the effective
date of such assignment), and (iii) such alternate lender shall have been
approved in writing by the Administrative Agent, such approval not to be
unreasonably withheld.

7.13     Further Assurances

         The Borrower hereby agrees from time to time, to do and perform any and
all acts and to execute any and all further instruments required or reasonably
requested by the Administrative Agent more fully to effect the purposes of this
Article 7 and the issuance of the Letters of Credit hereunder.

7.14     Nature of Obligations; Indemnities

         7.14.1 The obligations of the Borrower hereunder shall be absolute and
unconditional under any and all circumstances and irrespective of any set off,
compensation, counterclaim or defense to payment which the Borrower may have or
have had against the Administrative Agent, any Lender or any beneficiary of a
Letter of Credit. The Borrower assumes all risks of the acts or omissions of the
users of the Letters of Credit and all risks of the misuse of the Letters of
Credit. Neither the Administrative Agent, any of its correspondents nor any
Lender shall be responsible: (i) for the form, validity, sufficiency, accuracy,





                                       70

<PAGE>



genuineness or legal effect of any document specified in any applications for
any of the Letters of Credit, even if it should in fact prove to be in any or
all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for
the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any of the Letters of Credit or any of the
rights or benefits thereunder or proceeds thereof in whole or in part, which may
prove to be invalid or ineffective for any reason; (iii) for failure of any
draft to bear any reference or adequate reference to any of the Letters of
Credit, or failure of anyone to note the amount of any draft on the reverse of
any of the Letters of Credit or to surrender or to take up any of the Letters of
Credit or to send forward any such document apart from drafts as required by the
terms of any of the Letters of Credit; (iv) for error, omissions, interruptions
or delays in transmission or delivery of any messages, by mail, cable,
telegraph, telex or otherwise, whether or not they be in cipher; (v) for any
error, neglect, default, suspension or insolvency of any correspondents of the
Administrative Agent; (vi) for error in translation or for errors in
interpretation of technical terms; (vii) for any loss or delay, in the
transmission or otherwise, of any such document or draft or of proceeds thereof;
or (viii) for any other circumstances whatsoever in making or failing to make
payment under a Letter of Credit; provided that in each of the circumstances
referred to in clauses (i) through (viii) above the Borrower shall have a claim
against the Administrative Agent, and the Administrative Agent shall be liable
to the Borrower, to the extent, but only to the extent, of any direct, as
opposed to consequential, damages suffered by the Borrower which the Borrower
proves were caused by the Administrative Agent's wilful misconduct or gross
negligence. None of the above shall affect, impair or prevent the vesting of any
of the rights or powers of the Administrative Agent or any of the Lenders.

         7.14.2 In furtherance and extension and not in limitation of the
specific provisions hereinabove in this Article 7 set forth, (i) any action
taken or omitted by the Administrative Agent or by any of its respective
correspondents under or in connection with any of the Letters of Credit, if
taken or omitted in good faith and without wilful misconduct or gross
negligence, shall be binding upon the Borrower and shall not put the
Administrative Agent or its respective correspondents under any resulting
liability to the Borrower and (ii) the Administrative Agent may, without wilful
misconduct or gross negligence, accept documents that appear on their face to be
in order, without responsibility for further investigation, regardless of any
notice or information to the contrary; provided, that if the Administrative
Agent shall receive written notification from both the beneficiary of a Letter
of Credit and the Borrower that sufficiently identifies (in the opinion of the
Administrative Agent) documents to be presented to the Administrative Agent
which are not to be honored, the Administrative Agent agrees that it will not
honor such documents.

         7.14.3 The Borrower hereby agrees at all times to protect, indemnify
and save harmless the Administrative Agent and each Lender participating in a
Letter of Credit, from and against any and all claims, actions, suits and other
legal proceedings, and from and against any and all losses, claims, demands,
liabilities and damages, which they or any of them may, at any time, sustain or
incur by reason of or in consequence of or arising out of the issuance of any of
the Letters of Credit (all of the foregoing, collectively, the "indemnified
liabilities"), it being the intention of the parties that this Agreement shall





                                       71

<PAGE>



be construed and applied to protect and indemnify each of the Administrative
Agent and each Lender participating in a Letter of Credit against any and all
risks involved in the issuance of all of the Letters of Credit, all of which
risks, whether or not foreseeable, being hereby assumed by the Borrower,
including, without limitation, any and all risks of all acts by any Governmental
Authority and any and all claims by correspondents used in connection with a
Letter of Credit, provided that the Borrower shall not have any obligation
hereunder to an indemnified party with respect to indemnified liabilities
arising from the gross negligence or wilful misconduct of such indemnified
party. Neither the Administrative Agent nor any Lender shall, in any way, be
liable for any failure by it or anyone else to pay a draft drawn under any of
the Letters of Credit as a result of any acts, whether rightful or wrongful, of
any Governmental Authority or any correspondent used in connection with a Letter
of Credit or any other cause not readily within their control or the control of
their respective correspondents. Without limiting the generality of the
foregoing, the Borrower shall be responsible for, and shall reimburse the
Administrative Agent forthwith upon its receipt of any demand therefor, any and
all commissions, fees and other charges paid or payable by the Administrative
Agent to any foreign lender which shall be an advising lender or a beneficiary
of a Letter of Credit which shall, in reliance thereon, have issued its own
letter of credit in respect of obligations of the Borrower.

7.15     Payments upon any Event of Default

         The Borrower agrees that upon the occurrence and during the continuance
of any Event of Default, in addition to all other rights and remedies, the
Administrative Agent shall at the request, or may with the consent, of the
Majority Lenders by notice to the Borrower demand, immediate delivery of cash
collateral, and the Borrower agrees to deliver such cash collateral upon demand,
in an amount equal to the maximum amount that may be available to be drawn at
any time prior to the stated expiry of all outstanding Letters of Credit,
provided that such cash collateral shall be immediately due and payable upon the
occurrence of any Event of Default described in Section 12.1.11. Such cash
collateral shall be deposited in a special cash collateral account to be held by
the Administrative Agent as collateral security and as a pledge for the payment
and performance of the Borrower's obligations under this Agreement to the Agents
and the Lenders.

                             CHANGE IN CIRCUMSTANCES

8.1      Substitute Basis - Alternate Interest Rate

         If a Lender determines in good faith that:

         8.1.1 adequate and fair means do not exist for ascertaining the rate of
interest on a Libor Loan Portion for the ensuing Interest Period,






                                       72

<PAGE>



         8.1.2 the making or the continuing of a Libor Loan Portion has become
impracticable by an event materially or adversely affecting the London interbank
market, or

         8.1.3 deposits in USDollars are not available to such Lender in the
London interbank market in sufficient amounts in the ordinary course of business
for the ensuing Interest Period in respect of a Libor Loan Portion, then, such
Lender may notify the Administrative Agent thereof and if such Lender so
notifies the Administrative Agent, the Administrative Agent shall promptly
notify the Borrower and the other Lenders in writing and, effective upon the
date such interest rate would otherwise become applicable, such Libor Loan
Portion shall be deemed for all purposes to be a Canadian Base Rate Advance and
the interest rate applicable thereto shall be the applicable Canadian Base Rate.

8.2      Increased Costs

         If, with respect to any Borrowing or accommodation of any kind or
nature provided by the Lenders under this Agreement (each such form of
accommodation being in this Section 8.2 referred to as a "Facility") and as a
result of or due to any change occurring after the date of this Agreement in any
Law, or in the interpretation or application thereof by any Governmental
Authority charged with the administration thereof or by reason of any compliance
with any guideline, request or requirement from any fiscal, monetary or other
authority (whether or not having the force of law),

         (a) a Lender incurs a cost (which it would not otherwise have incurred)
         or becomes liable to make a payment (calculated with reference to the
         amount outstanding under a Facility) with respect to continuing to
         provide or maintain a Facility or as a result of obligations of a
         Lender being outstanding hereunder in favor of third parties (other
         than a tax imposed on the overall income or net profits of such Lender
         or franchise taxes imposed in lieu thereof);

         (b) any reserve, special deposit or similar requirement is imposed or
         increased with respect to a Facility increasing the cost thereof to a
         Lender;

         (c) a Lender suffers or will suffer a reduction in the rate of return
         on its overall capital (other than a reduction by reason of any
         increase in the taxes referred to in (a) above) as a result of the
         amount of the capital that a Lender is required to maintain being
         increased or of any change in the manner in which a Lender is required
         to allocate its resources, or as a result of a requirement to attribute
         or allocate capital in respect of any undrawn portion of a Facility;

         (d) if there is any increase in the direct cost to a Lender of making
         available the Facility; or






                                       73

<PAGE>



         (e) a Lender becomes liable to make any payment (not being the payment
         of tax on its overall income or net profits or franchise taxes imposed
         in lieu thereof) on or calculated by reference to the amount of a
         Facility;

then and in each such case the Borrower shall, subject to the terms and
conditions of this Section 8.2, pay to such Lender such amount (herein called
the "Compensating Amount") as will compensate such Lender for and will indemnify
such Lender against such increases in cost or reductions of rate of return or
liability with respect to the Facility.

         After the occurrence of an event having the effect set out in (a), (b),
(c), (d) or (e) above entitling a Lender to the payment of a Compensating Amount
and such Lender determining to claim such Compensating Amount, such Lender shall
forthwith give notice to the Borrower of the Compensating Amount claimed with
details of the events giving rise thereto and shall at that time or within
twenty (20) days thereafter provide to the Borrower a certificate setting out in
reasonable detail a compilation of the Compensating Amount claimed or, if such
Lender is then unable to determine the Compensating Amount or the method of
compilation thereof an estimate of such Compensating Amount and/or the method or
the basis on which such Lender estimates the calculation will be made which
estimate will be confirmed or adjusted by the aforesaid certificate. The
certificate of a Lender with respect to the Compensating Amount shall be final
and conclusive in the absence of manifest error.

         The Borrower shall within thirty (30) days of receipt of such notice
from a Lender pay to such Lender the Compensating Amount (or the estimated
Compensating Amount) claimed but, if the Compensating Amount claimed and paid is
greater or lesser than the Compensating Amount as finally determined, such
Lender or the Borrower, as the case may be, shall pay to the other the amount
required to adjust the payment to the Compensating Amount required to be paid.
The obligation to pay such a Compensating Amount for subsequent periods will
continue, subject as herein provided, until the earlier of the termination of
the Facility affected by the event referred to in the notice given by such
Lender to the Borrower or the lapse or cessation of the event giving rise to the
Compensating Amount.

         A copy of any notice or certificate given pursuant to this Section 8.2
shall be given to the Administrative Agent at the same time as such notice or
certificate is given.

8.3      Illegality

         Notwithstanding anything to the contrary contained in this Agreement,
if any introduction of or change occurring after the date of this Agreement in
any Law, policy, exchange control, guideline or official directive (whether or
not having the force of law) or any change in the interpretation or application
thereof by any court or by any Governmental Authority charged with the
administration thereof makes it unlawful or prohibited for a Lender to make,
fund or maintain all or any Libor Loan Portion or the Canadian Base Rate Loan,
or to give effect to its obligations contemplated by this Agreement, such Lender





                                       74

<PAGE>



shall notify the Borrower and the Administrative Agent in writing of the change
and, within the period specified by such Lender in the notice, at the option of
the Borrower:

         8.3.1 if such introduction or change so affects the Canadian Base Rate
Loan, the Borrower shall elect (i) that the Borrowings in USDollars shall be
immediately converted into CDollars and interest thereon shall be payable at the
Canadian Rate, or (ii) to repay and, within the time required by the new law (or
at the end of any longer period that such Lender at its discretion may agree),
the Borrower shall repay the Borrowings in USDollars together with accrued
interest up to the date of payment and all other amounts which are due, and in
any such event the obligation of the Lenders to make any further Advance in
USDollars or to allow any conversion into USDollars shall terminate for so long
as any circumstance entitling any Lender to give such a notice shall continue;
or

         8.3.2 if such introduction or change so affects the Libor Loan Portion,
the Borrower shall elect (i) that interest on the Libor Loan Portion shall be
payable at the Canadian Rate, or (ii) to repay and, within the time required by
the new law (or at the end of any longer period that such Lender at its
discretion may agree), the Borrower shall repay the Libor Loan Portion, together
with accrued interest up to the date of payment and all other amounts which are
due, and in any such event the obligation of the Lenders to make any further
Libor Advance or to allow any conversion of an Advance into a Libor Advance
shall terminate for so long as any circumstance entitling any Lender to give
such a notice shall continue.


8.4      Indemnity

         If the Borrower converts or prepays any amounts pursuant to Section 8.3
in respect to a Libor Loan Portion on a day other than the last day of an
Interest Period in respect of such Libor Loan Portion, the Borrower shall on
demand pay to the Administrative Agent, the amount required to indemnify the
Lenders for any loss, cost or expense incurred as a result of such conversion or
prepayment including, without limitation, any costs incurred in liquidating or
maintaining or redeploying deposits or other funds obtained by the Lenders to
fund such Libor Loan Portion. A certificate of the Lenders setting out the basis
of the determination of the amount necessary to indemnify them shall, in the
absence of manifest error, be conclusive and binding for all purposes.

8.5      Replacement of a Lender

         In the event a Lender has given a notice to the Borrower pursuant to
Section 8.1, 8.2 or 8.3, the Borrower shall (subject to the terms hereof) be
entitled to require (with a copy to the Administrative Agent) the Lender having
given such notice to assign to an alternate lender in accordance with Section
16.1.7 all of such Lender's rights and obligations hereunder and such alternate
lender shall execute all such documents as may be reasonably required by the
Administrative Agent, the Borrower and such Lender to effect such assignment,
provided that (i) each such assignment shall be arranged by the Borrower (with





                                       75

<PAGE>



such reasonable assistance from such Lender as the Borrower may request) after
consultation with the Administrative Agent and shall be an assignment of all of
the rights and obligations of the assigning Lender under this Agreement, (ii) no
Lender shall be obligated to make any such assignment as a result of a demand by
the Borrower pursuant to this Section 8.5 unless and until such Lender shall
have received payment from either the Borrower or the assignee in an aggregate
amount at least equal to the aggregate outstanding principal amount of the Loan
and Bid Loan and any Money Market Loans owing to such Lender, together with
accrued interest thereon to the date of payment of such principal amount and all
other amounts payable to such Lender under this Agreement (including, without
limitation, payment of any amounts owing to such Lender pursuant to Section 8.1,
8.2 or 8.3, as applicable, prior to the effective date of such assignment),
(iii) such alternate lender shall have been approved in writing by the
Administrative Agent, such approval not to be unreasonably withheld, and (iv)
any such assignment shall be subject to the restrictions set forth in Section
16.1.3.

         Any payments received by the Administrative Agent for the account of

         The Borrower shall make all payments hereunder regardless of any
counterclaim, compensation or set-off.

9.7      Taxes

         The Borrower shall make all payments required under this Agreement free
and clear of, and exempt from, and without deduction for, or on account of, any
Tax imposed by the Crown or any political subdivision thereof, excluding, in the
case of each Lender and the Administrative Agent, Taxes on the overall income or
net profits (or franchise taxes imposed in lieu thereof) of such Lender or
Administrative Agent imposed by the Crown or any political subdivision thereof
or by any foreign jurisdiction in which such Lender or Administrative Agent is
organized or has its applicable lending office (all such non-excluded Taxes





                                       77

<PAGE>



being hereinafter referred to as "Section 9.7 Taxes"). If any Section 9.7 Tax is
deducted or withheld from any payment, the Borrower shall promptly remit to the
Administrative Agent the amount so deducted or withheld together with relevant
receipts from the taxing authority addressed to the Administrative Agent. If the
Borrower is prevented by operation of law or otherwise from paying, causing to
be paid or remitting such Section 9.7 Tax, the interest payable under this
Agreement will be increased to the rates necessary to yield and remit to the
Administrative Agent the principal sum advanced together with interest at the
rates specified in this Agreement after provision for payment of such Section
9.7 Tax. At the request of the Administrative Agent, the Borrower shall from
time to time execute and deliver any and all further documents as may be
necessary or advisable (to the extent reasonable and without material cost or
disadvantage to the Borrower) to give full force and effect to such increase in
the rate of interest. The Borrower further covenant to indemnify each Lender and
the Administrative Agent in respect of any claim or loss incurred as a result of
the Borrower's delay or failure to deduct or to withhold any such Section 9.7
Tax, including all penalties and interest.

         If any Lender or the Administrative Agent, as applicable, receives a
refund of or a credit for a Section 9.7 Tax for which a payment has been made by
the Borrower pursuant to this Section 9.7, which refund or credit in the good
faith judgment of such Lender or the Administrative Agent, as the case may be,
is attributable to such payment made by the Borrower, then the Lender or the
Administrative Agent, as the case may be, shall reimburse the Borrower for such
amount as the Lender or the Administrative Agent, as the case may be, determines
to be the proportion of the refund or credit as will leave it, after such
reimbursement, in no better or worse position than it would have been if the
payment had not been required. Each Lender and the Administrative Agent, as the
case may be, shall claim any refund or credit that it determines is available to
it, unless it concludes in its reasonable discretion that it would be adversely
affected by making such a claim.

         Each Lender and the Administrative Agent agrees that it will (i) take
all reasonable actions reasonably requested by the Borrower that are without
risk or material cost to such Lender or the Administrative Agent (as the case
may be) to maintain all exemptions available to it from withholding taxes
(whether available by treaty or existing administrative waiver), and (ii) to the
extent reasonable and without material cost to it, otherwise cooperate with the
Borrower to minimize any amounts payable by the Borrower under this Section.

9.8      Application of Payments

         All payments made by or on behalf of the Borrower to the Administrative
Agent for the account of the Lenders pursuant to this Agreement shall in each
instance be applied by the Administrative Agent in the following order:

Sections 9.8.2, 9.8.3 and 9.8.4 hereof;

         9.8.2 to amounts due pursuant to Article 5 and Section 7.9.1;





                                       78

<PAGE>




         9.8.3 to repayment of amounts due in respect of the Loan; and

         9.8.4 to repayment of amounts due in respect of Bid Loans and Money 
Market Loans;

provided that after acceleration pursuant to Section 12.2, payments shall be
applied as the Lenders, in their discretion, may from time to time determine,
provided that payments on the Loan, the Bid Loans and the Money Market Loans
shall be made on a pro rata basis after acceleration.

9.9      Expenses and Indemnity

         9.9.1 The Borrower shall supply all statements, reports, certificates,
opinions, appraisals and other documents or information required to be furnished
to the Lenders or the Administrative Agent pursuant to this Agreement without
cost to any Lender or to the Administrative Agent.

         9.9.2 The Borrower shall reimburse and indemnify the Administrative
Agent (for itself and on behalf of the Lenders) and the other Agents, on demand,
all of the legal fees and disbursements (and tax on goods and services in
respect thereof) of Arrangers' Counsel and costs and other out-of-pocket
expenses (and tax on goods and services in respect thereof) reasonably incurred
from time to time in connection with (i) the due diligence, negotiation,
preparation and execution of this Agreement and any other documents referred to
herein or contemplated hereby, (ii) the negotiation, preparation and execution
of all waivers, amendments and variations in relation to this Agreement and any
other documents referred to herein or contemplated hereby, (iii) the operation
and interpretation of this Agreement and any agreement among the Lenders and the
Administrative Agent concerning their respective rights, remedies, duties and
responsibilities, and (iv) the syndication or arrangement of the Credit and
publicity, advertising and signing in connection with the Credit. In addition,
the Borrower agrees to pay on demand all of the legal fees of the Administrative
Agent and each of the Lenders and disbursements and costs and expenses (and tax
on goods and services in respect thereof) reasonably incurred in connection with
the enforcement of, or the preservation of any rights under, this Agreement and
the preservation, enforcement and realization of any other documents referred to
herein or contemplated hereby.

In addition, the Borrower shall pay or indemnify the Administrative Agent and
the Lenders against any and all stamp, registration and similar taxes which may
be payable in connection with the entry into, the performance of and the
enforcement of this Agreement.

         9.9.3 Without prejudice to the rights of the Lenders under the
provisions of Section 5.6, the Borrower agrees to indemnify each Lender against
any loss or expense which it may sustain or incur in obtaining or redeploying
deposits as a result of the failure by the Borrower to pay when due any
principal of the Loan or a Bid Loan or a Money Market Loan for any reason to
borrow in accordance with a Notice of Borrowing or a Notice of Bid Borrowing or
other similar notice given by the Borrower to the Administrative Agent, to the

provisions hereof. A certificate of a Lender or the Administrative Agent setting
forth the basis for the determination of the interest due on overdue principal
or interest and of the amounts necessary to indemnify such Lender in respect of
such loss or expense, submitted to the Borrower, shall be conclusive and binding
for all purposes except in case of manifest error.

indemnify such Lender for any loss, cost or expense incurred by such Lender as a
result of such payment or conversion or failure to fulfil such conditions
including, without limitation, any loss or expense incurred in liquidating or in
maintaining or redeploying deposits or other funds obtained by such Lender to
fund or maintain an Acceptance or the Libor Loan or such Libor Loan Portion. A
certificate of a Lender setting out the basis of the determination of the amount
necessary to indemnify it shall, in the absence of manifest error, be conclusive
and binding for all purposes.

         9.9.5 The Borrower agrees to indemnify and hold the Administrative
Agent and each of the Lenders harmless from and against any and all reasonable
claims, damages, losses, liabilities and expenses incurred, suffered or

carrying out or performance of this Agreement or any matter or document

account of another party hereto, the Administrative Agent shall not be obliged
to make the same available to that other party hereto until it has been able to
establish that it has actually received such sum, but if it does pay out a sum
and it proves to be the case that it had not actually received the sum it paid
out, then the party hereto to whom such sum was so made available shall on
request ensure that the amount so made available is refunded to the
Administrative Agent, and shall on demand indemnify the Administrative Agent
against any cost or loss it may have suffered or incurred by reason of its
having paid out such sum prior to its having received such sum.

these terms and conditions in whole or in part in respect of any other Advance
or Bid Advance or Letter of Credit, as applicable.

10.5     Waiver by Lenders under Existing Credit Agreements.

issued on such date, and that no shares of capital stock of Target are subject
to the Voting Trust. Calculations under this Section 11.2 of the Fixed Charge

forma basis assuming, in each case, that the Merger was consummated on the first
day of such period and that no shares of capital stock of Target are subject to
the Voting Trust at any time during such period. Notwithstanding the foregoing,
if the Merger Agreement has terminated prior to the consummation of the Merger
or the Merger is otherwise abandoned and no Event of Default shall occur as a
result thereof, then the foregoing calculations shall not be made on a pro forma
basis and shall be based on the most recent financial statements of the Borrower
and its Consolidated Subsidiaries delivered to the Lenders hereunder.

of notice or lapse of time, or both, would constitute an Event of Default, shall
have occurred and be continuing, (ii) no condition or event shall exist in
respect of the Borrower after giving full effect to such merger, consolidation,

         of any Subsidiary of the Borrower or of Target or any Subsidiary of
         Target, or any sale or lease of such line or facility subject to
         retained trackage rights, which will, in the reasonable judgment of the
         Borrower, facilitate obtaining a final order of the STB approving the
         Borrower's acquisition of control of Target and its Subsidiaries, and
         which will be consummated or become effective only if any when such
         order becomes effective; (3) any grant of trackage, haulage, switching

termination (as applicable) referred to in clause (i) or (ii) would be (w) to
increase the consideration payable per share of Target Common Stock, (x) to
increase the aggregate amount of cash consideration to be paid by Merger Sub in
connection with the Tender Offer and the Merger, (y) to decrease the number of
shares constituting Minimum Shares set forth in the condition with respect to

adverse to the Lenders, without in each case obtaining the prior written consent

         11.4.9 permit Grand Trunk or any of its other Subsidiaries (i) to amend
or otherwise change the terms of any of the US Credit Documents described in
clauses (i) through (vii) of the second sentence of Section 15.13 thereof, or

reasonably be expected to result in a Material Adverse Effect; provided,
however, that such failure shall not constitute an Event of Default (i) if such
failure would not, if Target were a Subsidiary of the Borrower for all purposes
hereunder, constitute an Event of Default under any other Section of this
Article 12, and (ii) unless such failure shall remain unremedied for a period of
thirty (30) days.

12.2     Effect of a Default

         Upon the occurrence and during the continuation of any Event of
Default, the Administrative Agent shall at the request, or may with the consent,
of the Majority Lenders, by notice to the Borrower (i) declare the obligation of
the Lenders to make Advances or Bid Advances to the Borrower to be terminated,
whereupon the same shall forthwith terminate, and/or (ii) declare the Loan and
the Bid Loan, all interest accrued and unpaid thereon and all other amounts
payable under this Agreement to be forthwith due and payable, whereupon the Loan
and the Bid Loan, all such accrued interest and all such other amounts shall






                                       103

<PAGE>



become and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the
Borrower and each of the Guarantors. Thereupon the Borrower shall immediately
pay to the Administrative Agent all such amounts due and payable. In addition to
the foregoing, in the event of the institution of any proceeding against the
Borrower or a Material Subsidiary or the Borrower or any Material Subsidiary
making an assignment for the general benefit of creditors or otherwise
voluntarily initiating any proceeding in respect of its property or creditors
under any Law relating to bankruptcy, insolvency or organization or relief of
debtors the effect of which is to cause an automatic stay to come into effect
with respect to the Borrower or a Material Subsidiary or an actual or deemed
entry of an order for relief with respect to any proceeding instituted by or
against the Borrower or a Material Subsidiary under the U.S. Federal Bankruptcy
Code, the Bankruptcy and Insolvency Act (Canada) or the Companies' Creditors
Arrangement Act (Canada) (as amended, supplemented or replaced from time to
time), as may be applicable, or any other applicable bankruptcy or insolvency
laws which provide for an automatic stay, the obligation of each Lender to make
Advances or Bid Advances shall automatically be terminated and the Loan and the
Bid Loan, all interest accrued and unpaid thereon and all other amounts payable
under this Agreement shall automatically become due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower and each of the Guarantors. For greater
certainty, the Borrower and each of the Guarantors will be considered to be in
default of their obligations hereunder by the mere lapse of time provided herein
for performing such obligations, without any requirement of further notice or
other act of the Administrative Agent or the Lenders unless a notice is
specifically required hereunder.

12.3     Remedies Cumulative; No Waiver

         For greater certainty, it is expressly understood and agreed that the
rights and remedies of the Lenders and the Administrative Agent under this
Agreement are cumulative and are in addition to, not in substitution for, any
rights or remedies provided by law; no failure on the part of the Lenders or the
Administrative Agent to exercise, and no delay in exercising, any right or
remedy hereunder or thereunder shall operate as a waiver thereof, nor shall any
single or partial exercise by the Lenders or the Administrative Agent of any
right or remedy for a default or breach of any term, covenant, condition or
agreement herein contained prejudice or preclude any other or further exercise
thereof or the exercise of any other right or remedy for the same or any other
default or breach and shall not waive, alter, affect or prejudice any other
right or remedy.

12.4     Set-Off

         In addition to, and not in limitation of, any rights now or hereafter
granted under applicable Law, each Lender is hereby expressly authorized (but
not obliged), at any time or from time to time upon the occurrence and during
the continuation of an Event of Default, to set off or compensate and to
appropriate and to apply any and all deposits, general or special, matured or
unmatured, and any other Indebtedness at any time held by or owing by such
Lender to, or for the credit of, or the account of, the Borrower or any of the
Guarantors against and on account of the obligations and liabilities of the





                                       104

<PAGE>



Borrower or each of the Guarantors due and payable to such Lender under this
Agreement including, without limitation, all claims of any nature or description
arising out of, or connected with, this Agreement, irrespective of whether or
not any demand therefor has been made and although such obligations and
liabilities of, or claims against, the Borrower or any of the Guarantors, are
contingent or unmatured. Each Lender shall upon any such set-off, compensation
or appropriation give immediate notice to the Administrative Agent and the other
Lenders and thereafter give notice to the Borrower.

ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OBLIGATIONS THEREUNDER, MAY
BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE,
COUNTY AND CITY OF NEW YORK. BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH
LOAN PARTY, FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, IRREVOCABLY

                  (I) ACCEPTS GENERALLY AND UNCONDITIONALLY THE NONEX- CLUSIVE
         JURISDICTION AND VENUE OF SUCH COURTS;

                  (II) WAIVES ANY DEFENSE OF FORUM NON CONVENIENS;

                  (III) AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH
         PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED
         MAIL, RETURN RECEIPT REQUESTED, TO SUCH LOAN PARTY AT ITS ADDRESS

         SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER SUCH LOAN PARTY IN ANY
         SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE
         AND BINDING SERVICE IN EVERY RESPECT;

                  (V) AGREES THAT LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN
         ANY OTHER MANNER PERMITTED BY LAW OR TO BRING PROCEEDINGS AGAINST SUCH
         LOAN PARTY IN THE COURTS OF ANY OTHER JURISDICTION; AND

                  (VI) AGREES THAT THE PROVISIONS OF THIS SECTION 14.2 RELATING
         TO JURISDICTION AND VENUE SHALL BE BINDING AND ENFORCEABLE TO THE
         FULLEST EXTENT PERMISSIBLE UNDER NEW YORK GENERAL OBLIGATIONS LAW
         SECTION 5-1402 OR OTHERWISE.

To the extent that any Loan Party now or hereafter may be entitled, in any
jurisdiction in which proceedings may at any time be commenced with respect to
this Agreement, to claim for itself or its revenues, assets or properties any
sovereign immunity (including, without limitation, immunity from service of
process, jurisdiction, suit, judgment, counterclaim, enforcement of or execution
on a judgment, attachment prior to the judgment, attachment in aid of execution
of a judgment or other legal process), and to the extent that in any
jurisdiction there may be attributed any such sovereign immunity (whether or not





                                       106

<PAGE>



claimed), each Loan Party hereby irrevocably undertakes not to claim and hereby
irrevocably waives any such immunity to the fullest extent permitted by law.

14.3     Judgment Currency

         14.3.1 If for any purpose, including the obtaining of judgment in any
court, it is necessary to convert a sum due hereunder from the currency in which
it is payable (the "Payment Currency") into another currency (the "Judgment
Currency"), the parties hereto agree, to the fullest extent that they may
lawfully and effectively do so, that the rate of exchange used shall be that at
which, in accordance with normal banking procedures, the Administrative Agent
could purchase the Payment Currency with the Judgment Currency in the New York
foreign exchange market on the Business Day preceding the date of final
judgment.

         14.3.2 The obligation of the Borrower in respect of any sum due from it
to the Lenders or the Administrative Agent hereunder shall, notwithstanding any
judgment or payment in a currency other than the Payment Currency, be discharged
only to the extent that on the Business Day following receipt by the
Administrative Agent of any sum so paid or adjudged to be so due in the Judgment
Currency the Administrative Agent may in accordance with normal banking
procedures, purchase the Payment Currency with the amount of the Judgment
Currency so paid or adjudged to be due; if the amount in the Payment Currency so
purchased is less than the sum originally due to the Lenders and the
Administrative Agent in the Payment Currency, the Borrower and each Guarantor
agrees, as a separate obligation and additional cause of action and
notwithstanding any such payment or judgment, to indemnify the Lenders and the
Administrative Agent against such loss and if the amount in the Payment Currency
so purchased exceeds the sum originally due to the Lenders and the
Administrative Agent in the Payment Currency, the Lenders and the Administrative
Agent agree to remit to the Borrower such excess.

         14.3.3 The term "rate of exchange" in this Section 14.3 means the spot
rate at which the Administrative Agent, in accordance with normal practices, is
able on the relevant date to purchase the Payment Currency with the Judgment
Currency and includes any premium and costs of exchange payable in connection
with the purchase.


                                   ARTICLE 15

                           THE AGENTS AND THE LENDERS

15.1     Authorization of Agents

         Each Lender hereby irrevocably appoints and authorizes each of the
Arrangers, the Advisor, the Syndication Agent, the Co-Documentation Agents and
the Administrative Agent to act as its agent hereunder with such powers as are
expressly delegated to the such Agent by the terms of this Agreement and the
Intercreditor Agreement, together with such other powers as are reasonably
incidental thereto; each Lender hereby authorizes and confirms the appointment





                                       107

<PAGE>



by Administrative Agent of Bank of Montreal as Repayment Agent under the
Intercreditor Agreement; and each Lender and Administrative Agent hereby
authorizes Repayment Agent to act as its agent in accordance with the terms of
the Intercreditor Agreement. Each Agent shall have no duties or responsibilities
except those expressly set forth in this Agreement or, in the case of the
Administrative Agent and the Repayment Agent, in the Intercreditor Agreement. As
to any matters not expressly provided for by this Agreement, the Administrative
Agent shall act hereunder or in connection herewith in accordance with
instructions of the Majority Lenders but, in the absence of any such
instructions, the Administrative Agent may (but shall not be obliged to) take
such action as it deems it necessary to protect the rights of the Lenders, and
any such instructions and any action taken by the Administrative Agent in
accordance herewith shall be binding upon all the Lenders. Each Agent shall not,
by reason of this Agreement, or, in the case of the Repayment Agent, by reason
of the Intercreditor Agreement, be deemed to be a trustee for the benefit of any
Lender, the Borrower, the Guarantors or any other Person. None of the Agents nor
any of their respective directors, officers, employees or agents shall be
responsible to the Lenders for any recitals, statements, representations or
warranties contained in this Agreement or in any certificate or other document
referred to, or provided for in, or received by any of them under, this
Agreement, for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement, or any other document referred to, or provided
for, herein or any collateral provided for hereby or for any failure by the
Borrower or any of the Guarantors to perform its obligations hereunder. The
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. None of the Agents nor any of their respective
directors, officers, employees or agents shall be responsible for any action
taken or omitted to be taken by it or them under or in connection herewith,
except for its or their own gross negligence or wilful misconduct. As of the
date on which Syndication Agent notifies the Borrower that it has concluded its
primary syndication of the Loan and Commitments, all obligations of the
Arrangers, the Advisor and the Syndication Agent, in such capacities hereunder,
shall terminate.

15.2     Agents' Responsibility

         15.2.1 Each Agent shall be entitled to rely upon any certificate,
notice or other document (including any cable or telegram) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper person or persons, and upon advice and statements of legal advisers,
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat each Lender as the holder of the
Participation in the Loan made by such Lender and as the holder of its share of
any Bid Loans and the holder of Money Market Loans made by it for all purposes
hereof unless and until an assignment or transfer has been accepted by the
Borrower and the Guarantors and the Administrative Agent in accordance with
Article 16.

         15.2.2 The Administrative Agent shall not be deemed to have knowledge
of the occurrence of an Event of Default unless the Administrative Agent has
received notice from a Lender or the Borrower or a Guarantor describing such an





                                       108

<PAGE>



Event of Default and stating that such notice is a "Notice of Default". In the
event that the Administrative Agent receives such a notice of the occurrence of
an Event of Default, the Administrative Agent shall promptly give notice thereof
to the Lenders. The Administrative Agent shall take such action with respect to
such Event of Default as shall be directed by the Majority Lenders, provided
that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obliged to) take such
action, or refrain from taking such action, with respect to such an Event of
Default as it shall deem advisable in the best interest of the Lenders.

         15.2.3 The Agents shall have no responsibility (i) to the Borrower or
any of the Guarantors on account of the failure of any Lender to perform its
obligations hereunder, or (iii) to any Lender on account of the failure of the
Borrower or any of the Guarantors to perform its obligations hereunder.

         15.2.4 Each of the Lenders severally represents and warrants to the
Agents that it has made its own independent investigation of the financial
condition and affairs of each of the Borrower and each of the Guarantors in
connection with the making and continuation of its Participation in the Loan or
its Bid Advances or Money Market Loans hereunder and has not relied on any
information provided to such Lender by any Agent in connection herewith, and
each Lender represents and warrants to the Agents that it shall continue to make
its own independent appraisal of the creditworthiness of the Borrower and each
of the Guarantors while the Loan or any Bid Loan or any Money Market Loan is
outstanding or any Commitment is in force.

15.3     Rights of Agents as Lenders

         With respect to its Commitments and its Participation in the Loan and
any Bid Loans made by it, each Agent in its capacity as a Lender shall have the
same rights and powers hereunder as any other Lender and may exercise the same
as though it were not acting as an Agent and the terms "Lender" or "Lenders"
shall, unless the context otherwise indicates, include such Agent in its
capacity as a Lender. Each Agent may (without having to account therefor to any
Lender) accept deposits from, lend money to and generally engage in any kind of
banking, or other business with the Borrower or any of the Guarantors as if it
were not acting as an Agent.

15.4     Indemnity

         The Lenders agree to indemnify each Agent (to the extent not otherwise
reimbursed by the Borrower or the Guarantors) rateably in accordance with their
respective Participation in the Loan (or, if no Advances have been made,
rateably in accordance with their respective Commitments), for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
cost, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by, or asserted against, such Agent in any way relating to
or arising out of this Agreement or any other documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby





                                       109

<PAGE>



(excluding, unless an Event of Default is apprehended or has occurred and is
continuing, normal administrative costs and expenses incidental to the
performance of its agency duties hereunder) or the enforcement of any of the
terms hereof or of any such other documents, provided that no Lender shall be
liable for any of the foregoing to the extent they arise from such Agent's gross
negligence or wilful misconduct.

15.5     Notice by Administrative Agent to Lenders

         Promptly after its receipt thereof, the Administrative Agent will
forward to each Lender a copy of each report, notice or other document required
by this Agreement to be delivered to the Administrative Agent for such Lender.

15.6     Protection of Agents

         15.6.1 No Agent shall be required to keep itself informed as to the
performance or observance by the Borrower or any of the Guarantors of this
Agreement or any other document referred to or provided for herein or to inspect
the properties or books of the Borrower or any of the Guarantors. Except for
notices, reports and other documents and information expressly required to be
furnished to the Lenders by an Agent hereunder, or, in the case of the Repayment
Agent, in accordance with the Intercreditor Agreement, such Agent shall have no
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs or financial condition of the Borrower or any
of the Guarantors which may come into the possession of such Agent. Nothing in
this Agreement, or, in the case of the Repayment Agent, in the Intercreditor
Agreement, shall oblige any Agent to disclose any information relating to the
Borrower or any of the Guarantors if such disclosure would or might in the
opinion of such Agent constitute a breach of any law or duty of secrecy or
confidence.

         15.6.2 Unless the Administrative Agent shall have been notified in
writing or by tested cable by any Lender prior to the date of an Advance or Bid
Advance requested hereunder that such Lender does not intend to make available
to the Administrative Agent such Lender's Participation in such Advance or Bid
Advance, the Administrative Agent may assume that such Lender has made such
Lender's Participation in such Advance or Bid Advance available to the
Administrative Agent on the date of such Advance or Bid Advance and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such corresponding amount is not in fact
made available to the Administrative Agent by such Lender, the Administrative
Agent shall be entitled to recover such amount (together with interest thereon
at the rate determined by the Administrative Agent as being its cost of funds in
the circumstances) on demand from such Lender or, if such Lender fails to
reimburse the Administrative Agent for such amount on demand, from the Borrower.

         15.6.3 Unless the Administrative Agent shall have been notified in
writing or by cable by the Borrower prior to the date on which any payment is
due hereunder that the Borrower does not intend to make such payment, the
Administrative Agent may assume that the Borrower has made such payment when so





                                       110

<PAGE>



due and the Administrative Agent may, in reliance upon such assumption, make
available to each Lender on such payment date an amount equal to such Lender's
pro rata share of such assumed payment. If it proves to be the case that the
Borrower has not in fact made such payment to the Administrative Agent, each
Lender shall forthwith on demand repay to the Administrative Agent the amount
made available to such Lender (together with interest at the rate determined by
the Administrative Agent as being its cost of funds in the circumstances).

15.7     Notice by Lenders to Administrative Agent

         Each Lender shall endeavor to use its best efforts to notify the
Administrative Agent of the occurrence of any event which by the giving of
notice or lapse of time or both would constitute an Event of Default forthwith
upon becoming aware of such event and of any legal proceeding such Lender
intends to take against the Borrower or any of the Guarantors in virtue of this
Agreement, but no Lender shall be liable if it fails to give such notice to the
Administrative Agent.

15.8     Resignation of Administrative Agent

         Subject to the appointment and acceptance of a successor Administrative
Agent (as provided below) (i) the Administrative Agent may resign at any time by
giving not less than thirty (30) days written notice thereof to the Lenders and
the Borrower, and (ii) the Administrative Agent may be removed at any time with
cause by the Majority Lenders by giving not less than thirty (30) days written
notice of their intention to do so to the Administrative Agent and the Borrower.
Upon such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent, which, if no Event of Default has
occurred and is continuing, must be acceptable to the Borrower. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation or receiving of notice of
removal, then the retiring Administrative Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent which, if no Event of Default has
occurred and is continuing, must be acceptable to the Borrower.

         If (i) the Total Commitment has been cancelled or terminated, (ii) the
Loan has been repaid, and (iii) the Administrative Agent has no outstanding Bid
Loans, the Administrative Agent may resign at any time by giving not less than
thirty (30) days' written notice thereof to the Lenders with outstanding Bid
Loans and the Borrower. If no agreement is reached by the parties to whom such
notice is given within such thirty (30) day period on the appointment of a
successor Administrative Agent, the Administrative Agent may appoint as a
successor Administrative Agent the Lender with the highest amount of outstanding
Bid Loans and such Lender shall become the Administrative Agent effective on
such appointment.

         Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, or upon the appointment by the
Administrative Agent of a successor Administrative Agent as aforesaid, such





                                       111

<PAGE>



successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent, the provisions of this 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 the Administrative Agent.

15.9     Sharing Among the Lenders

         The Lenders agree among themselves that, except as otherwise provided
for by the provisions of this Agreement, all sums received by the Administrative
Agent in its capacity as agent of the Lenders, for the ratable account of the
Lenders relative to this Agreement or any other document contemplated hereby
(whether received by voluntary payment, by the exercise of the right of set-off
or compensation or by counterclaim, cross action or as proceeds of realization
of any security) shall be shared by each Lender pro rata, in accordance with
their respective Participations and each Lender undertakes to do all such things
as may be reasonably required to give full effect to this Section 15.9. If any
sum which is so shared is later recovered from the Lender who originally
received it, each of the other Lenders shall restore its proportionate share of
such sum to such Lender, without interest.

         If any Lender obtains any payment (whether voluntary, involuntary or
through the exercise of any right of set-off or compensation or by counterclaim,
cross-action or as proceeds of realization of any security) on account of the
Loan in excess of its ratable share of payments on account of the Loan obtained
by all the Lenders, such Lender shall promptly deliver such amount to the
Administrative Agent for distribution to all Lenders pro rata in accordance with
their respective Participations.

         Each Lender agrees with the other Lenders that it will not, without the
prior written consent of the other Lenders, take or obtain any Lien on any
property of the Borrower or any Material Subsidiary to secure the obligations of
the Borrower or any of the Guarantors hereunder, except for the benefit of all
Lenders or as may otherwise be required by Law.

15.10    Intercreditor Agreement

         Each Lender hereby further authorizes Administrative Agent and
Repayment Agent, on behalf of and for the benefit of Lenders, to enter into the
Intercreditor Agreement, and each Lender agrees to be bound by the terms of the
Intercreditor Agreement.

15.11    Provisions for the Benefit of Lenders Only

         The provisions of this Article 15 relating to the rights and
obligations of the Lenders and Administrative Agent inter se shall be operative
as between the Lenders and Agents only, and the Borrower and the Guarantors
shall not have any rights or obligations under or be entitled to rely for any
purposes upon such provisions except for Sections 15.8 and 15.14.





                                       112

15.12    Amendment of Article 15
 
         Except for such provisions of Section 15.8 and Section 15.14 that
relate to the Borrower, the provisions of this Article 15 may be amended or
added to, from time to time, by execution by the Administrative Agent and the
Lenders of an instrument in writing and such instrument in writing shall validly
and effectively amend or add to any or all of the provisions of this Article 15
affecting the Lenders without requiring the execution of such instrument in
writing by the Borrower or any of the Guarantors. Notwithstanding the foregoing
sentence, for so long as no Event of Default has occurred and is continuing, the
second and third sentences of Section 15.13 cannot be amended without the
consent of the Borrower.

15.13    Authorized Waivers, Variations and Omissions

         If so authorized in writing by Majority Lenders, the Administrative
Agent may grant waivers, consents, vary the terms of this Agreement, and do or
omit to do all such acts and things in connection herewith or therewith. Except
with the prior written agreement of all the Lenders, nothing in this Section
15.13 shall authorize (i) any increase in the Total Commitment or subject the
Lenders to any additional financial or other material obligations, (ii) any
extension of the Term Loan Maturity Date, (iii) any extension of the Revolving
Loan Commitment Termination Date, (iv) any change in the definition of Majority
Lenders, (v) any reduction in any of the interest rates or fees (other than
agency fees payable to the Administrative Agent) provided for in this Agreement,
(vi) postpone any date fixed for any payment of interest or fees or (vii) any
amendments to any guarantees, security, if any, or Section 15.9 or this Section
15.13. Save as otherwise provided in Article 15 and in Section 16.1.2, all
instructions, decisions, approvals, consents or actions referred to in this
Agreement and required of the Lenders shall be made, taken or given by the
Majority Lenders. No amendment, waiver or consent shall, unless in writing and
signed by the applicable Agent in addition to the Lenders required herein to
take such action, affect the rights or duties of such Agent under this
Agreement. Notwithstanding anything in this Agreement to the contrary, (a) in
the event Majority Lenders or all Lenders shall consent to any amendment,
modification or waiver of any provision contained in Articles 2, 10, 11 or 12
(other than Sections 12.1.1, 12.1.2 and 12.1.11) of this Agreement, or the
definitions in Article 1 as used in such Articles, including without limitation
any waiver of compliance therewith as a condition to making any Advance or Bid
Advance, such amendment, modification or waiver shall not be effective
(notwithstanding approval thereof by Majority Lenders or all Lenders) with
respect to either this Agreement or the US Credit Agreement unless such
amendment, modification or waiver is effective with respect to both such
agreements and any fees which are paid by the Borrower or any of its
Subsidiaries to obtain consent to any such amendment, modification or waiver are
paid on a ratable basis to Lenders and "Lenders" (as defined in the US Credit
Agreement) who consent to such amendment, modification or waiver, and the
Lenders hereunder hereby consent to any such amendment, modification or waiver
in this Agreement and the US Credit Agreement as is necessary to give effect to
this sentence, and (b) any change in the definition of Majority Lenders or to
this Section 15.13 shall require the prior written agreement of all Lenders and
all "Lenders" as defined in the US Credit Agreement.

15.14             Dissenting Lenders

         If a Lender (in this Section 15.14 called a "Dissenting Lender")
withholds its consent or its approval following a request of the Borrower as
provided in this Agreement and, as a result, the consent of all the Lenders or
the Majority Lenders, as the case may be, cannot be obtained in connection with
such request, the Borrower may, provided at least 51% of the Lenders based on
the amount of the Total Commitment in effect from time to time have consented to
such request, by giving notice to each Dissenting Lender and to the Agent within
ten (10) days of being advised by the Administrative Agent of whether the
Lenders or the Majority Lenders, as the case may be, have consented to such
request, designate an alternate lender (which need not be an existing Lender) to
purchase an assignment in accordance with Section 16.1.7 of such Dissenting
Lender's Commitments and outstanding Loan and Bid Loan and Money Market Loans
(which alternative lender shall purchase such assignment prior to the expiry of
such ten (10) day delay) provided that no Lender shall be obligated to make any
such assignment as a result of a demand by the Borrower pursuant to this Section
15.14 unless said assignment is done on a without warranty basis and unless and
until such Dissenting Lender shall have received one or more payments from
either the Borrower or one or more assignees in an aggregate amount at least
equal to the aggregate outstanding principal amount of the Loan and Bid Loan and
Money Market Loans owing to such Dissenting Lender, together with accrued
interest thereon to the date of payment of such principal amount and all other
amounts payable to such Dissenting Lender under this Agreement. Any such
alternate lender is subject to the Administrative Agent's prior written
approval, such approval not to be unreasonably withheld. Nothing contained
herein shall be deemed to obligate any Lender or the Administrative Agent to
agree to any such request made by the Borrower.

                             SUCCESSORS AND ASSIGNS

16.1     Successors and Assigns

         16.1.1 This Agreement shall become effective when it shall have been
executed by the Borrower, the Guarantors, the Administrative Agent, the
Arrangers, the Advisor, the Syndication Agent and each Lender and thereafter
shall be binding upon and enure to the benefit of the Borrower, the Guarantors,
the Administrative Agent, the Arrangers, the Advisor, the Syndication Agent, the
Lenders and their respective successors and permitted assigns.

         16.1.2 Neither the Borrower nor any of the Guarantors shall have the
right to assign their rights or obligations hereunder or any interest herein
without the prior written consent of all the Lenders, which consent may be
arbitrarily withheld.

         16.1.3 A Lender may (i) without notice to or consent of any Person,
grant participations in its interest in the Credit to one or more Persons (each





                                       114

<PAGE>



a "Participant"); or (ii) with the consent of the Borrower (but not the
Guarantors) which consent shall not be unreasonably withheld or delayed, assign
its rights and obligations in the Credit to one or more financial institutions
(each an "Assignee") in whole or in part, subject to the following limitations:

                           (w) any such Assignee shall be subject to approval by
         the Administrative Agent and no such consent of the Borrower or
         approval of the Administrative Agent shall be required for assignments
         by a Lender to an Affiliate of such Lender or to another Lender or
         during the occurrence and continuance of an Event of Default;

                           (x) no Lender shall assign its Commitments (except to
         Affiliates of such Lender and to other Lenders) in amounts less than
         US$10,000,000 (or such lesser amount as shall constitute the aggregate
         amount of the Commitments and Advances of such Lender) in the
         aggregate;

                           (y) no Lender may assign its Revolving Loan
         Commitment or Term Loan Commitment or Advances except together with a
         proportionate share of all Commitments and Advances held by such
         Lender; and

                           (z) notwithstanding anything to the contrary
         contained herein, no Lender may assign its interest in the Credit
         except to a resident of Canada within the meaning of the Income Tax Act
         (Canada).

Except in the case of an Assignee which has delivered an assumption agreement
pursuant to Section 16.1.7, the Participant or Assignee shall not have any
rights under this Agreement (such Person's rights against such Lender in respect
of such participations and assignments to be those set forth in the agreement
executed by such Lender in favor of such Person relating thereto and such Person
shall not constitute a "Lender" hereunder). With respect to all such
participations (i) the obligations under this Agreement of each Lender selling a
participation interest hereunder shall remain unmodified and fully effective and
enforceable against such Lender, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the party entitled to receive payments for all
purposes of this Agreement, (iv) the Borrower, the Administrative Agent and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, and
(v) such Lender shall not grant to its Participant(s) any rights to consent or
withhold consent to any action taken by such Lender or the Administrative Agent
under this Agreement other than action requiring the consent of all of the
Lenders hereunder.

         16.1.4 Subject to Section 16.1.9, the Lenders may deliver a copy of any
financial statement or any other information relating to the business, assets or
condition (financial and otherwise) of the Borrower and its Subsidiaries or the
Guarantors which may be furnished to them under this Agreement or otherwise to





                                       115

<PAGE>



any prospective or other Participant or Assignee to the extent reasonably
required by such Participant or Assignee in connection with its interest or the
proposed acquisition of an interest in the Credit or a Bid Loan or any Money
Market Loans.

         16.1.5 The Borrower and each of the Guarantors shall provide such
certificates, acknowledgements and further assurances in respect of this
Agreement and the Credit or a Bid Loan or a Money Market Loan as such Lender may
reasonably require in connection with any participation or assignment pursuant
to Section 16.1.3.

         16.1.6 Except in the case of an Assignee which has delivered an
assumption agreement pursuant to Section 16.1.7:

         (a) a Lender granting a participation or making an assignment shall
         remain a "Lender" hereunder and shall act on behalf of all of its
         Participants and Assignees in all dealings with the Borrower and the
         Guarantors in respect of the Credit and the Bid Loans and any Money
         Market Loans;

         (b) the Participant or Assignee shall not constitute a "Lender" here-
         under; and

         (c) except with respect to Bankers' Acceptances, all amounts payable by
         the Borrower hereunder shall be determined as if such Lender had not
         granted such participation or made such assignment.

         16.1.7 A Lender may deliver to the Borrower, the Guarantors and the
Administrative Agent an agreement substantially in the form of Schedule 16.1.7
annexed hereto by which any Assignee of such Lender assumes the obligations and
agrees to be bound by all the terms and conditions of this Agreement, all as if
such Assignee had been an original party hereto. Upon any such assignment and
assumption of the obligations of such Lender by an Assignee:

         (a) the Administrative Agent shall, upon receipt of a fee of US$2,500
         from the Assignee (provided that such fee shall be paid by the Borrower
         in the event of any assignment pursuant to Section 7.12 or 8.5), record
         the assignment and any modified Commitments resulting therefrom; and

         (b) the assigning Lender, the Borrower and the Guarantors shall be
         released from their respective obligations hereunder (to the extent of
         such assignment and assumption) and thereafter shall not have any
         liability or obligations to each other to such extent, except in
         respect of matters arising prior to such assignment.

         In the event a Lender assigns the full amount of its Loan and
Commitments and such Lender has an outstanding Bid Loan and/or any Money Market
Loans at the time of such assignment, such Lender must also assign the full
amount of such Bid Rate Loans and Money Market Loans to a Person which is a
Lender at the time of such assignment.

         16.1.8 The Borrower and each of the Guarantors hereby consents to the
disclosure by each Lender to any Participant or Assignee of all information in
regard to this Agreement. The Borrower and each of the Guarantors further agrees
to co-operate fully with each Lender in connection with any transaction pursuant
to Section 16.1.7 and to execute and deliver such documents and assurances as a
Lender may reasonably request in connection therewith including, without
limitation, the agreement referred to in Section 16.1.7.

         16.1.9 Each Lender and the Administrative Agent agrees (on behalf of
itself and each of its Affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with their customary procedures for handling confidential information
of this nature and in accordance with safe and sound lending practices, any
non-public information supplied to it by the Borrower or any of its Subsidiaries
pursuant to this Agreement (and which is not independently known to such Lender
or the Administrative Agent) provided that nothing herein shall limit the
disclosure of any such information (i) to the extent required by Law or judicial
process, (ii) to counsel for any of the Lender or the Administrative Agent,
(iii) to a Lender's examiners, auditors or accountants, (iv) to the
Administrative Agent or any other Lender, (v) in connection with any litigation
to which any one or more of the Lenders is a party, (vi) to any Affiliate of any
Lender or the Administrative Agent, or (vii) to any Assignee or Participant (or
prospective Assignee or Participant) so long as such Assignee or Participant (or
prospective Assignee or Participant) first executes and delivers to the
respective Lender a Confidentiality Agreement substantially in the form of
Schedule 16.1.9 annexed hereto; provided, further, that, unless specifically
prohibited by applicable Law or court order, each Lender shall, prior to
disclosure thereof, notify the Borrower of any request for disclosure of any
such non-public information (x) by any governmental agency or representative
thereof (other than any such request in connection with an examination of such
Lenders financial condition by such governmental agency), or (y) pursuant to
legal process; and provided finally that in no event shall any Lender or the
Administrative Agent be obligated or required to return any materials furnished
by the Borrower or any of its Subsidiaries.

         16.1.10 No Lender shall be entitled to grant a participation or an
assignment pursuant to Section 16.1.3 or to change its branch of account, as the
case may be, if, as a result, the Borrower would be required to pay or reimburse
the Participant or Assignee for any Taxes under Section 9.7 or any Compensating
Amount under Section 8.2.

         16.1.11 Each Lender listed on the signature pages hereof hereby
represents and warrants (i) that it has experience and expertise in the making
of loans such as the Term Loans and/or the Revolving Loans, as applicable; and
(ii) that it will make its Advances for its own account in the ordinary course
of its business and without a view to distribution of its interest in the Credit
within the meaning of the Securities Act or the Exchange Act or other federal
securities laws (it being understood that, subject to the provisions of this
Article 16, the disposition of such interests in the Credit shall at all times
remain within its exclusive control). Each Lender listed on the signature pages
hereof hereby represents and warrants that it is a resident of Canada within the





                                       117

<PAGE>



meaning of the Income Tax Act (Canada). Each Lender that becomes a party hereto
after the date hereof pursuant to an assignment from a Lender shall be deemed to
represent and warrant that it is a resident of Canada within the meaning of the
Income Tax Act (Canada).

                                   ARTICLE 17

                                    GUARANTEE

17.1     Guarantee

         Each of the Guarantors, for good and valuable consideration received,
hereby absolutely, irrevocably and unconditionally guarantees, as primary
obligor and not merely as surety, in favor of each of the Lenders and the
Administrative Agent, the prompt and complete payment when due, whether at
stated maturity, by acceleration or otherwise, of all present and future
obligations of the Borrower resulting from the terms and conditions of this
Agreement, including without limitation, the repayment of the Bid Loan and the
Loan and all reimbursement obligations under any Letters of Credit, together
with interest thereon and all fees and other amounts as provided in this
Agreement (such obligations being herein called the "Obligations"). Each of the
Guarantors shall be considered as primarily liable to the Lenders and the
Administrative Agent, and shall not be released nor its liability hereunder
limited or lessened by any variation or departure from the provisions of this
Agreement nor by the Lenders or the Administrative Agent's granting time, taking
or giving up securities, accepting compositions, granting releases or
discharges, or otherwise dealing with any Person, nor by any other thing
whatsoever, either of a like nature to the foregoing or otherwise whereby as
guarantor only, a Guarantor would or might be released, and none of the Lenders
or the Administrative Agent shall be bound to exhaust its recourse against the
Borrower or any other Person or any security it may hold before being entitled
to payment from each of the Guarantors. The Guarantors covenant and agree that
until such time as each of the Lenders and the Administrative Agent shall have
been indefeasibly paid in full all Obligations, no payment will be taken,
demanded, received or accepted by a Guarantor of or on account of the principal
amount of or interest of any indebtedness incurred by a Guarantor in fulfillment
of its obligations pursuant to this Section 17.1 or on any other indebtedness
payable by the Borrower, each of the Guarantors agreeing that this said
indebtedness shall, at all times, be fully subordinated to and rank in time and
right of payment junior to the Obligations, and each of the Guarantors hereby
renounces any rights of compensation and/or set-off and/or counterclaim. Without
limiting the foregoing, each of the Guarantors hereby expressly subordinates and
postpones all of its rights to the benefit of subrogation (whether contractual,
under the Bankruptcy Code, under common law or otherwise) and all contractual,
common law, statutory and other rights of reimbursement, contribution,
exoneration or indemnity (or any similar right) from or against the Borrower
which may have arisen in connection with this guarantee, and agrees not to
enforce or attempt to enforce any of the foregoing, until indefeasible full
repayment of the Obligations and the termination of all Letters of Credit and
the Total Commitment. Each of the Guarantors hereby determines and agrees that
the execution, delivery and performance of this Agreement by such Guarantor is
necessary and convenient to the conduct, promotion or attainment of the business





                                       118

<PAGE>



of the Borrower and the Guarantors and in furtherance of the corporate purposes
of the Guarantors. Notwithstanding anything herein to the contrary, the
obligations of CNR Properties arising under this Article 17 are solely with
respect to the obligations of Canadian National Railway Company under this
Agreement in its capacity as a Borrower. Upon the reasonable request of the
Administrative Agent, CNR Properties will execute a guarantee agreement with
substantially the same effect as this Article 17 in order to guarantee the
obligations of any future Borrower or any other future Guarantor under this
Agreement to the extent that CNR Properties is permitted to guarantee such
obligations under applicable Law.

17.2     Guarantee Absolute

         Each of the Guarantors guarantees that the Obligations will be paid
strictly in accordance with the terms of this Agreement, regardless of any Law,
regulation, or order now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Administrative Agent or the Lenders with
respect thereto. The liability of each of the Guarantors under this Agreement
shall be absolute and unconditional irrespective of:

         (i) any lack of validity or enforceability of any provisions of this
         Agreement, any Bankers' Acceptance or any other agreement or instrument
         relating to this Agreement;

         (ii) any change in the time, manner or place of payment of or in any
         other term of, all or any of the Obligations or any other amendment,
         restatement or waiver of or any consent to departure from this
         Agreement;

         (iii) any exchange, release or non-perfection of any collateral or any
         release or amendment or waiver of or consent to departure from any
         other guarantee, for all or any of the Obligations;

         (iv) the reconstruction, reorganization, consolidation, amalgamation or
         merger of the Borrower with or into any other Person, or the transfer,
         sale, lease or other disposition by the Borrower of all or
         substantially all of its assets or business to any other Person,
         whether or not affected in compliance with the provisions of this
         Agreement;

         (v) the illegality under any applicable Law of repayment of the
         Obligations or the adoption of any Law purporting to render any
         Obligations null and void;

         (vi) any defense, setoff or counterclaim which may at any time be
         available to or asserted by any Guarantor against the Administrative
         Agent or any Lender; or

         (vii) any other circumstance which might otherwise constitute a defense
         available to, or a discharge of, the Borrower or a guarantor.

         The liability of each of the Guarantors under this Article 17 shall
continue to be effective or be reinstated, as the case may be, if at any time





                                       119

<PAGE>



any payment of any of the Obligations is rescinded or must otherwise be returned
by the Administrative Agent or any Lender upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, all as though such payment had not
been made.

17.3     Waiver

         Each of the Guarantors hereby waives promptness, diligence, notice of
acceptance, presentment, protest, demand, notice of default, and any other
notice with respect to any of the Obligations and its liability hereunder and
any requirement that the Administrative Agent or any Lender protect, secure,
perfect or insure any Lien, if any, or any property subject thereto or exhaust
any right or take any action against the Borrower or any other Person or any
collateral.

17.4     Continuing Guarantee

         The obligations of each of the Guarantors under this Article 17 shall
be a continuing guarantee and shall:

         (i) remain in full force and effect until payment in full of the
         Obligations and all other amounts payable under this Agreement;

         (ii) be binding upon each of the Guarantors, its successors and 
         assigns; and

         (iii) enure to the benefit of and be enforceable by the Lenders, the
         Administrative Agent and their respective successors, transferees and
         assigns.

         Without limiting the generality of the foregoing clause (iii), upon any
assignment by any Lender of all or any part of any interest in this Agreement by
it to any other Person in accordance with the terms of this Agreement, such
other Person shall thereupon become vested with all the rights in respect
thereof granted to such Lender herein or otherwise, subject, however, to the
provisions of this Agreement concerning the Administrative Agent and subject to
compliance with Section 16.1.7.

17.5     Fraudulent Conveyance Limitation

         17.5.1 Anything contained in this Article 17 to the contrary
notwithstanding, if any Fraudulent Transfer Law (as hereinafter defined) is
determined by a court of competent jurisdiction to be applicable to the
obligations of any Guarantor under this Article 17, such obligations of such
Guarantor hereunder shall be limited to a maximum aggregate amount equal to the
largest amount that would not render its obligations hereunder subject to
avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11
of the United States Code or any applicable provisions of comparable state law
(collectively, the "Fraudulent Transfer Laws"), in each case after giving effect
to all other liabilities of such Guarantor, contingent or otherwise, that are
relevant under the Fraudulent Transfer Laws (specifically excluding, however,
any liabilities of such Guarantor (x) in respect of intercompany indebtedness to





                                       120

<PAGE>



the Borrower or other affiliates of the Borrower to the extent that such
indebtedness would be discharged in an amount equal to the amount paid by such
Guarantor hereunder and (y) under any guaranty of subordinated indebtedness
which guaranty contains a limitation as to maximum amount similar to that set
forth in this Section 17.5.1, pursuant to which the liability of such Guarantor
hereunder is included in the liabilities taken into account in determining such
maximum amount) and after giving effect as assets to the value (as determined
under the applicable provisions of the Fraudulent Transfer Laws) of any rights
to subrogation, reimbursement, indemnification or contribution of such Guarantor
pursuant to applicable law or pursuant to the terms of any agreement (including
without limitation any such right of contribution under Section 17.5.2).

         17.5.2 Guarantors together desire to allocate among themselves, in a
fair and equitable manner, their obligations arising under this Article 17.
Accordingly, in the event any payment or distribution is made on any date by any
Guarantor under this Article 17 (a "Funding Guarantor") that exceeds its Fair
Share (as defined below) as of such date, that Funding Guarantor shall be
entitled to a contribution from each of the other Guarantors in the amount of
such other Guarantor's Fair Share Shortfall (as defined below) as of such date,
with the result that all such contributions will cause each Guarantor's
Aggregate Payments (as defined below) to equal its Fair Share as of such date.
"Fair Share" means, with respect to a Guarantor as of any date of determination,
an amount equal to (i) the ratio of (x) the Adjusted Maximum Amount (as defined
below) with respect to such Guarantor to (y) the aggregate of the Adjusted
Maximum Amounts with respect to all Guarantors, multiplied by (ii) the aggregate
amount paid or distributed on or before such date by all Funding Guarantors
under this Article 17 in respect of the obligations guarantied. "Fair Share
Shortfall" means, with respect to a Guarantor as of any date of determination,
the excess, if any, of the Fair Share of such Guarantor over the Aggregate
Payments of such Guarantor. "Adjusted Maximum Amount" means, with respect to a
Guarantor as of any date of determination, the maximum aggregate amount of the
obligations of such Guarantor under this Article 17, determined as of such date
in accordance with Section 17.5.1; provided that, solely for purposes of
calculating the "Adjusted Maximum Amount" with respect to any Guarantor for
purposes of this Section 17.5.2, any assets or liabilities of such Guarantor
arising by virtue of any rights to subrogation, reimbursement or indemnification
or any rights to or obligations of contribution hereunder shall not be
considered as assets or liabilities of such Guarantor. "Aggregate Payments"
means, with respect to a Guarantor as of any date of determination, an amount
equal to (i) the aggregate amount of all payments and distributions made on or
before such date by such Guarantor in respect of this Guaranty (including,
without limitation, in respect of this Section 17.5.2) minus (ii) the aggregate
amount of all payments received on or before such date by such Guarantor from
the other Guarantors as contributions under this Section 17.5.2. The amounts
payable as contributions hereunder shall be determined as of the date on which
the related payment or distribution is made by the applicable Funding Guarantor.
The allocation among Guarantors of their obligations as set forth in this
Section 17.5.2 shall not be construed in any way to limit the liability of any
Guarantor hereunder.

17.6     Taxes

         17.6.1 Any and all payments to the Lenders by the Guarantors in respect
of the Obligations, shall be made free and clear of and without deduction or
withholding for any and all present or future Taxes excluding, in the case of
each Lender and the Administrative Agent, (i) Taxes on the overall income or net
profits (or franchise taxes imposed in lieu thereof) of such Lender or
Administrative Agent imposed by any jurisdiction in which such Lender or
Administrative Agent is organized or has its Applicable Lending Office, and (ii)
in the case of each Lender and the Administrative Agent, Taxes imposed solely by
reason of the Lender or the Administrative Agent (as the case may be) doing
business in the jurisdiction imposing such Tax, other than as a result of this
Agreement or any transaction contemplated hereby (all Taxes, other than such
excluded Taxes, being hereinafter referred to as "Section 17.6 Taxes") unless
such Taxes are required by law or the administration thereof to be deducted or
withheld. If any Guarantor shall be required by Law or the administration
thereof to deduct or withhold any such Section 17.6 Taxes from or in respect of
any such amount payable hereunder then, (i) the amount payable shall be
increased as may be necessary so that after making all required deductions or
withholdings (including deductions or withholdings applicable to additional
amounts paid under this Section 17.6), the Lenders receive an amount equal to
the amount they would have received if no such deduction or withholding had been
made; (ii) such Guarantor shall make such deductions or withholdings; and (iii)
such Guarantor forthwith shall pay the full amount deducted or withheld to the
relevant taxation or other authority in accordance with applicable Law.

         17.6.2 Each Guarantor agrees to pay forthwith any present or future
stamp documentary taxes or any other excise or property taxes, charges or
similar levies (all such taxes, charges and levies being herein referred to as
"Other Taxes") imposed by any jurisdiction (or any political subdivision or
taxing authority thereof or therein) which arise from any payment made by the
Guarantors hereunder.

         17.6.3 Each Guarantor agrees to indemnify the Lenders for the full
amount of (i) Section 17.6 Taxes and Other Taxes not deducted or withheld and
paid by such Guarantors in accordance with Section 17.6.1 and 17.6.2 to the
relevant taxation or other authority and (ii) any Section 17.6 Taxes or Other
Taxes imposed by any jurisdiction on amounts payable by any Guarantor under this
Section 17.6, in each case paid by the Lenders and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not any such Taxes or Other Taxes were correctly or legally asserted;
provided that, if such Taxes or Other Taxes were incorrectly or illegally
imposed, such Lender shall, at the reasonable request of the applicable
Guarantor, take all reasonable actions that are without risk or material cost to
such Lender to claim and obtain refunds with respect to such Taxes or Other
Taxes and will promptly after receipt thereof remit such refunds to such
Guarantor. Payment under this indemnification shall be made within 15 days from
the date the Administrative Agent or the relevant Lenders make written demand
therefor. A certificate as to the amount of such Taxes or Other Taxes, providing
reasonable details of the calculation thereof, and evidence of payment thereof
submitted to the relevant Guarantor by the Administrative Agent shall be prima
facie evidence of the amount due from such Guarantor to the Administrative Agent
or the Lenders.






                                       122

<PAGE>



         17.6.4 Each Guarantor shall furnish to the Administrative Agent and the
relevant Lenders the original or a certified copy of a receipt evidencing any
payment of Taxes or other Taxes made by such Guarantor, as soon as such receipt
becomes available.

         Each Lender and the Administrative Agent agrees that it will (i) take
all reasonable actions reasonably requested by the Guarantor that are without
risk or material cost to such Lender or the Administrative Agent (as the case
may be) to maintain all exemptions, if any, available to it from withholding
taxes (whether available by treaty or existing administrative waiver), and (ii)
to the extent reasonable and without material cost to it, otherwise cooperate
with the Guarantor to minimize any amounts payable by the Guarantor under this
Section.

         If the Guarantor is required to pay additional amounts to or for the
account of any Lender pursuant to this section 17.6, then such Lender will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Lender, would not impose material cost on such Lender
and is not otherwise disadvantageous to such Lender.

         17.6.5 The provisions of this Section 17.6 shall survive the
termination of the Agreement and the repayment of all Advances and Bid Advances
and all Money Market Loans.



                                   ARTICLE 18

                                  MISCELLANEOUS

18.1     Severability

         Any provision of this Agreement which is or becomes prohibited or
unenforceable in any jurisdiction shall not invalidate, affect or impair the
remaining provisions hereof and any such prohibition or unenforceability in any
jurisdiction does not invalidate or render unenforceable any such provision in
any other jurisdiction.

18.2     Amendments, Waivers, Etc.

         Except as specifically provided in Section 15.12, no amendment,
modification or waiver of any provision of, and no waiver of the strict
observance, performance or compliance by the Borrower or each of the Guarantors
with any term, covenant, condition or agreement contained in this Agreement and
no indulgence granted by the Administrative Agent or the Lenders or consent to
any departure by the Borrower or any of the Guarantors therefrom, shall in any
event be effective unless it shall be in writing and signed by, as the case may
be, the Majority Lenders or the Administrative Agent on behalf of the Lenders or
the Majority Lenders, as required, and the Borrower and each of the Guarantors,





                                       123

<PAGE>



and then such amendment, modification, waiver or consent shall be effective only
in the specific instance and for the specific purpose for which it is given.

18.3     Direct Obligation

         Notwithstanding any other provision hereof, the Borrower shall be
obligated directly towards each of the Lenders in respect of the Participation
of each of the Lenders as well as any other amounts which may be payable by the
Borrower pursuant to or in connection with this Agreement or any Borrowings. The
obligations of each of the Lenders are independent from one another, are not
joint, and may not be increased, reduced, extinguished or otherwise affected due
to the default of another Lender pursuant hereto. Any default of any party
hereto in the performance of its obligations shall not release any of the other
parties hereto from the performance of any of their respective obligations.

18.4     Sharing of Information

         The Borrower and each of the Guarantors agrees that the Administrative
Agent and the Lenders may share amongst themselves any information which any of
them may possess concerning the Borrower or any of the Guarantors in respect of
the Borrower's and each of the Guarantors' undertakings, obligations or
indebtedness towards any Lender pursuant to this Agreement or otherwise, as well
as any payment received from the Borrower or any of the Guarantors by any
Lender. Without limiting the generality of the foregoing, the Administrative
Agent may disclose to any Lender and the Borrower and any of the Guarantors any
information contained in any notices, consents, certificates, documents or other
instruments or writings delivered to it under or pursuant to this Agreement.

18.5     Term of Agreement

         This Agreement shall continue in full force and effect until both the
Total Commitment of the Lenders has terminated and all Obligations (other than
inchoate indemnification obligations with respect to claims, losses or
liabilities which have not yet arisen) of the Borrower and each of the
Guarantors under or pursuant to this Agreement have been indefeasibly paid and
satisfied in full.

18.6     Further Assurances

         The Borrower and each of the Guarantors agrees to do, execute,
acknowledge, deliver or cause to be done, executed, acknowledged or delivered
all such further acts, deeds, documents, opinions and assurances as may be
reasonably requested by the Administrative Agent or any Lender from time to time
during the term hereof for the purpose of effecting the transactions
contemplated hereby.

18.7     Execution in Counterparts

         This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute but one and the same agreement.

18.8     Language

         The parties hereby confirm their express wish that the present
Agreement and all documents and agreements directly and indirectly related

50.1% (on a fully diluted basis) of the outstanding shares of common stock, par
value US$0.001 per share, of Illinois Central Corporation, a Delaware

Stock").

                  B. Merger Sub has offered to purchase not less than 50.1% (on
a fully diluted basis) and not more than 46,051,761 of the issued and

                  C. Simultaneously with the purchase of the Target Common
Stock, such Target Common Stock purchased by Merger Sub will be deposited into

         Merger Agreement with Target being the surviving corporation in such
         merger (such surviving corporation is sometimes referred to herein as
         the "Surviving Corporation");

                           (2) If Merger Sub has purchased 46,051,761 shares of
         Target Common Stock, each of the shares of Target Common Stock
         outstanding immediately before the consummation of the Merger (other
         than shares to be cancelled as described in clause (4) below and shares
         held by those who perfect appraisal rights, if any, under state law)
         will be converted into the right to receive a number of common shares,
         without par value, of the Company (the "Company Common Stock")
         determined in accordance with the Merger Agreement;

                           (3) If Merger Sub has purchased less than 46,051,761
         shares of Target Common Stock, each of the shares of Target Common
         Stock outstanding immediately before the consummation of the Merger
         (other than shares to be cancelled as described in clause (4) below and
         shares held by those who perfect appraisal rights, if any, under state
         law) will be converted into the right to receive (x) a number of shares
         of Company Common Stock determined in accordance with the Merger
         Agreement and (y) a cash payment in an amount determined in accordance
         with the Merger Agreement;

                           (4) Each of the shares of Target Common Stock
         outstanding immediately before the consummation of the Merger held by
         Merger Sub, Target or any of their respective direct or indirect
         Subsidiaries (including shares held in the Voting
         Trust) (the "Other Target Shares") shall be cancelled and retired
         without payment of any consideration therefor;

                           (5) As a result of the Merger, each of the shares of
         the capital stock of Merger Sub outstanding immediately before the
         consummation of the Merger will be converted into and become one fully
         paid and nonassessable share of common stock of Surviving Corporation
         (the "Surviving Corporation Common Stock"); and

                           (6) Following the Merger, all of the outstanding

adviser" as such terms are defined in the Investment Advisers Act of 1940, as
amended;

         2.1.19 except as set forth on Schedule 2.1.19 annexed hereto, there is
no fact known to the Company or its Subsidiaries which could have a Material
Adverse Effect which has not been fully disclosed to the Administrative Agent or
the Lenders other than matters of a general economic nature;

         2.1.20 the Company and each of its Material Subsidiaries possesses all
material franchises, certificates, licenses, permits and other authorizations or
exemptions from regulatory authorities and other Governmental Authorities, free
from burdensome restrictions or known conflict with the rights of others, that
are necessary for the ownership, maintenance and operation of its properties and
assets and the conduct of its business as now conducted and as proposed to be
conducted, and neither the Company nor any of the Material Subsidiaries is in
violation of any thereof, which failure to possess or violation could have a
Material Adverse Effect;

         2.1.21 each Canadian Plan is in compliance in all material respects
with all applicable Laws; neither the Company nor any of its Material
Subsidiaries has incurred any material liability to any Canadian Plan, whether
on account of any failure to meet the contribution or minimum funding
requirements applicable thereto, or relating to the administration or
termination of any Canadian Plan and no event has occurred and no condition
exists which presents a material risk that the Company or any of its Material
Subsidiaries will incur liabilities on account of the foregoing circumstances
which are material in the aggregate. Except as disclosed in Schedule 2.1.21, no
Canadian Plan is a Deficient Canadian Plan;

         2.1.22 each of the Borrower and each ERISA Affiliate of the Borrower
(a) has fulfilled its obligations under the minimum funding standards of ERISA
and the Code with respect to each Plan and (b) is in compliance in all respects
with the presently applicable provisions of ERISA and the Code with respect to
each Plan except for failures to comply which could not, singularly or in the
aggregate, have a Material Adverse Effect. Neither the Borrower nor any ERISA
Affiliate of the Borrower has (x) sought a waiver of the minimum funding
standard under Section 412 of the Code in respect of any Plan, (y) failed to
make any contribution or payment to any Plan or Multiemployer Plan or in respect
of any Benefit Arrangement, or made any amendment to any Plan or Benefit
Arrangement, which has resulted or could result in the imposition of a Lien
other than a Permitted Encumbrance of the type described in paragraphs (i)
through (x) in the definition of Permitted Encumbrances in Section 1.1 or the
posting of a bond or other security under ERISA or the Code, or (z) incurred any
liability under Title IV of ERISA, other than a liability to the PBGC for
premiums under Section 4007 of ERISA, which could in any case have a Material
Adverse Effect. No Prohibited Transaction and no Reportable Event has occurred
with respect to any such Plan within the past five (5) years which could have a
Material Adverse Effect. The execution, delivery and performance of this
Agreement does not constitute a Prohibited Transaction. Except as disclosed in
Schedule 2.1.22, there is no material unfunded benefit liability with respect to
any Plan of the Borrower or its ERISA Affiliates which could have a Material
Adverse Effect. Except to the extent required under Section 4980B of the Code
and for a US$5,000 payment made upon the death of a retired employee, no Plan
provides health or welfare benefits (through the purchase of insurance or
otherwise) for any retired or former employee of the Borrower, any of its
Subsidiaries or any of their respective ERISA Affiliates.

         2.1.23 the Borrower will use the proceeds of the Advances only for the
purposes permitted under Sections 3.1 and 3.2. No part of the proceeds of any
Advance will be used by the Borrower in violation of Regulation G, Regulation T,
Regulation U or Regulation X of the Board of Governors of the Federal Reserve
System;

         2.1.24 the aggregate Tangible Net Worth of the Excluded Subsidiaries
does not exceed C$50,000,000;

         2.1.25 the Company has delivered to Lenders complete and correct copies
of each Related Agreement and of all exhibits and schedules thereto;

         2.1.26 subject to the qualifications set forth therein, each of the
representations and warranties given by the Company and Merger Sub in the Merger
Agreement is true and correct in all material respects as of the date hereof (or
as of any earlier date to which such representation and warranty specifically
relates) and will be true and correct in all material respects as of the Initial
Funding Date (or such earlier date as the case may be), and to the Borrower's
actual knowledge, each representation and warranty made by Target in the Merger
Agreement is true and correct as of the date hereof (or as of any earlier date
to which such representation or warranty specifically relates) and will be true
and correct as of the Initial Funding Date;

         2.1.27 notwithstanding anything in the Merger Agreement to the
contrary, the representations and warranties of the Borrower set forth in
subsection 2.1.26 shall, solely for purposes of this Agreement, survive the
Initial Funding Date for the benefit of Lenders; and

         2.1.28 the Tender Offer Materials and other information furnished by
any Loan Party to any Agent or any Lender for purposes of or in connection with
this Agreement or any transaction contemplated hereby (including any such
information contained in the Confidential Information Memorandum with respect to
the credit facilities created hereunder, the Form F-4 that was submitted to the
Securities and Exchange Commission on a confidential basis on March 6, 1998 and
any information contained in any filings made by the Company after the date
which is one year prior to the Closing Date with the Securities and Exchange
Commission which are publicly available), taken as a whole, as of the date of
preparation thereof, do not contain any untrue statement of a material fact or
omits to state a material fact (known to any Loan Party, in the case of any
document not furnished by it) necessary in order to make the statements
contained therein not misleading in light of the circumstances in which the same
were made. Any projections and pro forma financial information contained in the
Financial Projections and the Pro Forma Closing Balance Sheet are based upon
good faith estimates and assumptions believed by the Company to be reasonable at
the time made, it being recognized by Lenders that such projections as to future
events are not to be viewed as facts and that actual results during the period
or periods covered by any such projections may differ from the projected
results. As of the date hereof, there are no facts known (or which should upon
the reasonable exercise of diligence be known) to any Loan Party (other than
matters of a general economic nature) that, individually or in the aggregate,
could reasonably be expected to result in a Material Adverse Effect and that
have not been disclosed herein or in other documents, certificates and
statements furnished to Lenders for use in connection with the transactions
contemplated hereby.

2.2      Survival of Representations and Warranties

         The representations and warranties herein set forth or contained in any
certificates or documents delivered to the Administrative Agent or the Lenders
pursuant hereto shall not be prejudiced by and shall survive any accommodation
hereunder and shall continue in full force and effect until the full payment and
performance of all obligations of the Borrower and the Guarantors hereunder or
pursuant hereto. The representations and warranties in Section 2.1, except for
Section 2.1.3 and Sections 2.1.14, 2.1.21, 2.1.22, 2.1.26 and 2.1.27 and except
that clause (i) of Section 2.1.7 shall be read as if it referred to the most
recent financial statements of the Company delivered by the Company to the
Administrative Agent pursuant to Section 11.1.2 and the date in Section 2.1.17
shall be the last day of the most recent fiscal year for which the Company has
furnished its audited annual consolidated statements to the Administrative Agent
pursuant to Section 11.1.2, shall be deemed to be repeated upon each Drawdown
Date (other than a Drawdown Date on which there is no increase in the amount of
credit extended under this Agreement), on the date of each Bid Borrowing and on
the date each Money Market Loan is made.


                                    ARTICLE 3

                                   THE CREDIT

3.1      Term Loan Commitment; Use of Proceeds of Term Loans

         3.1.1 Relying on each of the representations and warranties set out in
Article 2 and subject to the terms of this Agreement, each Lender severally and
not jointly, agrees to make its Term Loan Commitment available to the Borrower
as term loans on the Initial Funding Date in USDollars by way of US Base Rate
Advances or Libor Advances; provided that (a) a Lender shall have no obligation
to make any Term Loan if the amount thereof exceeds its then Available Term Loan
Commitment and (b) in no event shall the principal amount of the Term Loans made
to the Borrower exceed US$320,000,000.

         3.1.2 The Borrower agrees to use the proceeds of the Term Loans,
together with other funds, solely as follows:

         (i) to contribute the proceeds thereof, directly or indirectly, to the
         capital of Merger Sub to provide the consideration for Merger Sub to
         purchase the Tendered Target Shares, to pay or cause to be paid the
         consideration for any shares of Target Common Stock that have been
         converted into the right to receive a cash payment pursuant to the
         Merger Agreement and to pay or cause to be paid the purchase price of
         any other Target Common Stock purchased in any manner whatsoever, in an
         aggregate amount not to exceed US$1,796,018,679.00;

         (ii) to repay in full all Indebtedness outstanding under the Existing
         Credit Agreements in an amount not to exceed US$30,000,000, together
         with accrued and unpaid interest thereon and fees and expenses payable
         in connection therewith; and

         (iii) to pay or cause to be paid Transaction Costs.

3.2      Revolving Loan Commitment; Use of Proceeds of Revolving Loans

         3.2.1 Relying on each of the representations and warranties set out in
Article 2 and subject to the terms of this Agreement, each Lender severally and
not jointly, agrees to make its Revolving Loan Commitment available to the
Borrower on a revolving basis, during the period from the Initial Funding Date
until the Revolving Loan Commitment Termination Date applicable to such Lender,
in USDollars by way of US Base Rate Advances or Libor Advances or Letters of
Credit in accordance with Article 7; provided that a Lender shall have no
obligation to make any Advance under this Section 3.2.1 if the amount thereof
exceeds its then Available Revolving Loan Commitment and (b) in no event shall
the Total Utilization of Revolving Loan Commitments exceed the aggregate
Revolving Loan Commitments of all Lenders and provided further, that the
Revolving Loan Commitment of a Lender shall be deemed used from time to time to
the extent of the aggregate amount of the Money Market Loans then outstanding
owed to such Lender, and such deemed use of such Lender's Revolving Loan
Commitment shall be applied to reduce the amount of Advances available from such
Lender (such deemed use of such Lender's Revolving Loan Commitment being a
"Money Market Reduction"). No Advance shall be required to be made by a Lender
if, after giving effect to each applicable Money Market Reduction in effect
immediately prior to such Advance (and to the application of the proceeds of
such Advance), the aggregate Advances of any Lender would exceed the amount
permitted by the prior sentence.

         3.2.2 The Borrower agrees to use the proceeds of the Revolving Loans,
together with other funds, solely as follows:

         (i) to contribute the proceeds thereof, directly or indirectly, to the
         capital of Merger Sub to provide the consideration for Merger Sub to
         purchase the Tendered Target Shares, to pay or cause to be paid the
         consideration for any shares of Target Common Stock that have been
         converted into the right to receive a cash payment pursuant to the
         Merger Agreement and to pay or cause to be paid the purchase price of

         (ii) to repay in full all Indebtedness outstanding under the Existing
         Credit Agreements in an amount not to exceed US$30,000,000, together
         with accrued and unpaid interest thereon and fees and expenses payable
         in connection therewith;

         (iii)    to pay or cause to be paid Transaction Costs; and

         (iv) for general corporate purposes including, without limitation,
         commercial paper backstop.

         3.3.1 Term Loans. Subject to the terms and conditions hereof, upon
giving to the Administrative Agent prior written notice in accordance with
Section 3.6 by means of a Notice of Borrowing, the Borrower may borrow on the
Initial Funding Date from each Lender up to the amount of its Available Term
Loan Commitment in USDollars by way of Libor Advances, or US Base Rate Advances
in a minimum amount of ten million USDollars (US$10,000,000) or such larger
amount as is an integral multiple of one million USDollars (US$1,000,000) (or
the remaining balance of the Available Term Loan Commitment, if less than such
amount), provided that in no event shall the principal amount of the Term Loans
made to the Borrower exceed US$320,000,000. In each Notice of Borrowing in which
the Borrower has elected to pay interest at a margin or margins relative to
LIBOR on all or part of the Borrowing, the Borrower shall specify the duration
it selects for the initial Interest Period with respect to such Libor Loan
Portion in accordance with Section 5.4. Each Notice of Borrowing shall be
irrevocable and binding on the Borrower. The Drawdown Date for the Term Loans
shall be the Initial Funding Date, which shall be a Business Day. The Borrower
may make only one Borrowing under the Term Loan Commitments. Amounts borrowed
under this Section 3.3.1 and subsequently repaid or prepaid may not be
reborrowed.

         3.3.2 Revolving Loans. Subject to the terms and conditions hereof, from
time to time during the period from the Initial Funding Date until the Revolving
Loan Commitment Termination Date, upon giving to the Administrative Agent prior
written notice in accordance with Section 3.6 by means of a Notice of Borrowing,
the Borrower may from time to time borrow from each Lender up to the amount of
its Available Revolving Loan Commitment by way of Libor Advances or US Base Rate
Advances in a minimum amount of ten million USDollars (US$10,000,000) or such
larger amount as is an integral multiple of one million USDollars (US$1,000,000)
(or the remaining balance of the Available Revolving Loan Commitment, if less
than such amount), provided that in no event shall the Total Utilization of
Revolving Loan Commitments (after giving effect to any Money Market Reduction)
exceed the aggregate Revolving Loan Commitments of all Lenders. In each Notice
of Borrowing in which the Borrower has elected to pay interest at a margin or
margins relative to LIBOR on all or part of the Borrowing, the Borrower shall
specify the duration it selects for the initial Interest Period with respect to
such Libor Loan Portion in accordance with Section 5.4. Each Notice of Borrowing
shall be irrevocable and binding on the Borrower. In all cases the Drawdown Date
shall be a Business Day. Within the limits of each Lender's Revolving Loan
Commitment, the Borrower may borrow under this Section 3.3.2, repay pursuant to
Section 4.2 and reborrow under this Section 3.3.2.

3.4      Bid Advances

         3.4.1 Each Lender severally agrees that the Borrower may make Bid
Borrowings under this Section 3.4 from time to time on any Business Day during
the period from the Initial Funding Date until the date occurring one (1) month
(or, in the case of Fixed Rate Advances, thirty (30) days) prior to the
Revolving Loan Commitment Termination Date in the manner set forth below;
provided that (i) no Bid Borrowing may be requested or made until such time as
US$1,700,000,000 in original aggregate principal amount of Advances, Canadian
Term Loans and Canadian Revolving Loans have been made under this Agreement and
the Canadian Credit Agreement and (ii) following the making of each Bid
Borrowing, the Total Utilization of Revolving Loan Commitments (after giving
effect to any Money Market Reduction) shall not exceed the aggregate Revolving
Loan Commitments of all Lenders.

                  (i) The Borrower may request a Bid Borrowing under this
         Section 3.4 by delivering to the Administrative Agent, by telecopier,
         confirmed immediately in writing, not later than 10:00 a.m. (Chicago
         time) (A) at least three (3) Business Days prior to the date of the
         proposed Bid Borrowing, if the Borrower selects a Fixed Rate Advance,
         or (B) at least four (4) Business Days prior to the date of the
         proposed Bid Borrowing, if the Borrower selects a Libor Advance, a
         notice of a Bid Borrowing (a "Notice of Bid Borrowings"), in
         substantially the form of Schedule 3.4.1, specifying therein if the
         Borrower selects a Fixed Rate Advance or a Libor Advance, the date and
         aggregate amount of the proposed Bid Borrowing, the maturity date for
         repayment of each Bid Advance to be made as part of such Bid Borrowing
         (which maturity date may not be earlier than the date occurring one (1)
         month (or, in the case of Fixed Rate Advances, thirty (30) days) after
         the date of such Bid Borrowing or, in any case, may not be later
         than one hundred and eighty (180) days after the date of such Bid
         Borrowing, or, if earlier, the Revolving Loan Commitment Termination
         Date), the interest payment date or dates relating thereto, the right,
         if any, to prepay any principal amount of any Bid Advance to be made a
         part of such Bid Borrowing on such terms as the Borrower shall therein
         specify, and any other terms to be applicable to such Bid Borrowing.
         The Administrative Agent shall in turn promptly notify each Lender of
         each request for a Bid Borrowing received by it from the Borrower by
         sending such Lender a copy of the related Notice of Bid Borrowing.

                  (ii) Each Lender may, if, in its sole discretion, it elects to
         do so, irrevocably offer to make one or more Bid Advances to the
         Borrower as part of such proposed Bid Borrowing at a fixed rate or
         rates, or a margin or margins relative to LIBOR, as requested by the
         Borrower, by notifying the Administrative Agent via telecopier (which
         shall give prompt notice thereof to the Borrower), (A) after 9:00 a.m.
         but before 9:30 a.m. (Chicago time) on the date of such proposed Bid
         Borrowing, in the case of a Notice of Bid Borrowing for a Fixed Rate
         Advance and (B) after 1:30 p.m. but before 2:00 p.m. (Chicago time)
         three (3) Business Days before the date of such proposed Bid Borrowing,
         in the case of a Notice of Bid Borrowing for a Libor Advance, of the
         minimum amount (which amount shall be not less than US$1,000,000) and
         maximum amount of each Bid Advance which such Lender would be willing
         to make as part of such proposed Bid Borrowing (which amounts may,
         subject to the proviso to the first sentence of Section 3.4.1, exceed
         such Lender's Revolving Loan Commitment), the fixed rate or rates, or a
         margin or margins relative to LIBOR, as requested by the Borrower,
         which such Lender would be willing to accept for such Bid Advance and
         such Lender's Applicable Lending Office with respect to such Bid
         Advance; provided that if the Administrative Agent in its capacity as a
         Lender shall, in its sole discretion, elect to make any such offer, it
         shall notify the Borrower of such offer by 9:00 a.m. (Chicago time) on
         the date of such proposed Bid Borrowing, in the case of a Notice of Bid
         Borrowing for a Fixed Rate Advance and by 1:30 p.m. (Chicago time)
         three (3) Business Days before the date of such proposed Bid Borrowing,
         in the case of a Notice of Bid Borrowing for a Libor Advance. In the
         event that the Administrative Agent does not receive a notice from a
         Lender making an offer for a Bid Advance by the applicable time set out
         above in this paragraph (ii), such Lender shall be deemed for all
         purposes to have elected not to make such an offer. The failure by any
         Lender to give such notice shall not cause such Lender to be obligated
         to make any Bid Advance as part of such proposed Bid Borrowing.

                  (iii) The Borrower shall, in turn, (A) before 10:30 a.m.
         (Chicago time) on the date of such proposed Bid Borrowing, in the case
         of a Notice of Bid Borrowing for a Fixed Rate Advance and (B) before
         3:00 p.m. (Chicago time) three (3) Business Days before the date of
         such proposed Bid Borrowing, in the case of a Notice of Bid Borrowing
         for a Libor Advance, either:

                  (1) cancel such Bid Borrowing by giving the Administrative 
                  Agent notice to that effect, or

                  (2) accept one or more of the offers made by any Lender or
                  Lenders pursuant to paragraph (ii) above, in its sole
                  discretion, by giving notice to the Administrative Agent of
                  the amount of each Bid Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the
                  Administrative Agent on behalf of such Lender for such Bid
                  Advance pursuant to paragraph (ii) above) to be made by each
                  Lender as part of such Bid Borrowing, and reject any remaining
                  offers made by Lenders pursuant to paragraph (ii) above by
                  giving the Administrative Agent notice to that effect.

         The acceptance of offers by the Borrower pursuant to clause (2) of this
         paragraph (iii) shall be on the basis of ascending rates of interest or
         margins contained in the offers made by the Lenders pursuant to
         paragraph (ii) above; provided that, in the event that two or more of
         such offers contain the same rate of interest or margin for a greater
         aggregate principal amount than the amount specified in such Notice of
         Bid Borrowing less the aggregate principal amount of all such offers
         containing lower rates of interest that have been accepted by the
         Borrower pursuant to clause (2) of this paragraph (iii), The Borrower
         shall accept such offers at such rate of interest or margin in amounts
         allocated among the Lenders which made such offers pro rata according
         to the amounts so offered (or as nearly pro rata as shall be
         practicable after giving effect to the requirement that Bid Advances
         made in connection with a Bid Borrowing shall be a minimum amount of
         US$1,000,000).

                  (iv) If the Borrower notifies the Administrative Agent that
         such Bid Borrowing is cancelled pursuant to clause (1) of paragraph
         (iii) above, the Administrative Agent shall give prompt notice thereof
         to the Lenders and such Bid Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to clause (2) of paragraph (iii) above,
         the Administrative Agent shall in turn on the date of such acceptance
         notify (A) each Lender that has made an offer as described in paragraph
         (ii) above of the date and aggregate amount of such Bid Borrowing and
         whether or not any offer or offers made by such Lender pursuant to
         paragraph (ii) above have been accepted by the Borrower, (B) each
         Lender that is to make a Bid Advance as part of such Bid Borrowing of
         the amount of each Bid Advance to be made by such Lender as part of
         such Bid Borrowing, and (C) each Lender that is to make a Bid Advance
         as part of such Bid Borrowing, upon receipt, that the Administrative
         Agent has received forms of documents appearing to fulfill the
         applicable conditions set forth in Article 10.

                  (vi) Each Lender that is to make a Bid Advance as part of such
         Bid Borrowing shall, before 12:00 noon (Chicago time) on the date of
         such Bid Borrowing specified in the notice received from the
         Administrative Agent pursuant to clause (B) of the preceding paragraph
         (v) or any later time when such Lender shall have received notice from
         the Administrative Agent pursuant to clause (C) of the preceding
         paragraph (v), make available for the account of its Applicable Lending
         Office such Lender's ratable portion of such Bid Borrowing by
         depositing such portion in same day funds in the Administrative Agent's
         account specified in Section 9.1. Upon fulfillment of the applicable
         conditions set forth in Article 10, the Administrative Agent will
         promptly make available to the Borrower at the Administrative Agent's
         aforesaid address such funds as shall have
         actually been received by the Administrative Agent. Promptly after each
         Bid Borrowing, the Administrative Agent will notify each Lender of the
         amount of the Bid Borrowing.

         3.4.2 Each Bid Borrowing shall be in an aggregate amount of not less
than or US$10,000,000 or an integral multiple of US$1,000,000 respectively in
excess thereof. Following the making of each Bid Borrowing (and the application
of the proceeds thereof), the Borrower agrees that it shall be in compliance
with the limitations set forth in the proviso to the first sentence of Section
3.4.1. Except as otherwise provided in this Section 3.4, the provisions of this
Agreement dealing with Libor Loans shall apply, mutatis mutandis, to Bid
Borrowings at margins relative to LIBOR.

         3.4.3 Within the limits and on the conditions set forth in this Section
3.4, the Borrower may from time to time borrow under this Section 3.4, repay or
prepay pursuant to Section 3.4.4, and re-borrow under this Section 3.4; provided
that a Bid Borrowing shall not be made within four Business Days of the date
that any other Bid Borrowing is made.

         3.4.4 The Borrower shall repay to the Administrative Agent for the
account of each Lender which has made a Bid Advance, on the maturity date of
each Bid Advance (such maturity date being that specified by the Borrower for
repayment of such Bid Advance in the related Notice of Bid Borrowing delivered
pursuant to Section 3.4.1(i)), the then unpaid principal amount of such Bid
Advance. The Borrower shall have no right to prepay any principal amount of any
Bid Advance except on the terms specified for prepayment by the Borrower for
such Bid Advance in the related Notice of Bid Borrowing delivered pursuant to
Section 3.4.1(i) or otherwise with the consent of the Lender that has made the
relevant Bid Advance.

         3.4.5 The Borrower shall pay interest on the unpaid principal amount of
each Bid Advance from the date of such Bid Advance to the date the principal
amount of such Bid Advance is repaid in full, at the rate of interest for such
Bid Advance specified by the Lender making such Bid Advance in its notice with
respect thereto delivered pursuant to Section 3.4.1(ii), payable on the interest
payment date or dates specified by the Borrower for such Bid Advance in the
related Notice of Bid Borrowing delivered pursuant to Section 3.4.1(i).

3.5      Money Market Loans

         3.5.1 The Borrower may at any time and from time to time request any
one or more of the Lenders to make offers to make Money Market Loans to the
Borrower on any Business Day during the period from the date hereof until the
Revolving Loan Commitment Termination Date in the manner set forth below. Each
such Lender may, but shall have no obligation to, make such offer, and the
Borrower may, but shall have no obligation to, accept any such offers in the
manner set forth in this Section 3.5.

         3.5.2 In the event that the Borrower desires to borrow a Money Market
Loan from a Lender, the Borrower shall, prior to 11:00 a.m. (Montreal time),
request that such Lender provide a quotation to the Borrower of the amount and
terms under which such Lender would be willing to provide such Money Market
Loan. Each Money Market Loan shall be in USDollars in an amount of not less than
US$1,000,000 or an integral multiple of US$1,000,000 in excess thereof.

         3.5.3 In the event that the Borrower elects to accept a Lender's offer
for a Money Market Loan, the Borrower shall provide telephonic notice to such
Lender of its election in a timely manner after the time that such offer was
received by the Borrower. The failure of the Borrower to provide such notice of
acceptance in a timely manner shall be deemed to constitute a rejection of the
offer of such Lender. Any Money Market Loan to be made by a Lender pursuant to
this Section 3.5 shall be made by the Lender crediting an account specified by
the Borrower with the amount of such advance in same day funds in accordance
with the terms agreed upon for such Money Market Loan following receipt of the
Borrower's timely acceptance of the offer of such Lender with respect to such
Money Market Loan.

         3.5.4 The Borrower agrees to forward to the Lender with respect to a
Money Market Loan written evidence of such Money Market Loan by providing, on
the date upon which such Money Market Loan is made, documents, in form and
substance acceptable to both the Borrower and such Lender, executed and
delivered by a duly authorized officer of the Borrower, confirming the amount so
borrowed, the rate of interest applicable thereto and the maturity thereof (with
such Money Market Loan being due and payable on such date of maturity); provided
that the failure of the Borrower to provide such documents shall not impair the
obligation of the Borrower to repay any Money Market Loan borrowed by it. All
borrowings pursuant to this Section 3.5 shall bear interest at the rate quoted
to the Borrower by the relevant Lender in its quotation described in Section
3.5.2.

         3.5.5 In the event that all amounts then owing under this Agreement
become due and payable prior to their scheduled maturity, each Lender that has a
Money Market Loan outstanding may declare its Money Market Loans (with any
applicable interest thereon) to be immediately due and payable without the
consent of, or notice to, any other Lender; provided that if such event is an
Event of Default specified in Section 12.1.11, each Lender's Money Market Loans
(and any applicable interest thereon) shall automatically become immediately due
and payable.

         3.5.6 The Borrower and any Lender may at any time and from time to time
enter into written agreements that provide for procedures for soliciting and
extending Money Market Loans that differ from those specified in Sections 3.5.2
to 3.5.5, inclusive. As between the Borrower and such Lender such agreements
shall supersede the provisions of such sections to the extent specified therein.

         3.5.7 In the event that the availability under any Lender's Revolving
Loan Commitment (after giving effect to any applicable Money Market Reduction)
has been reduced to a level that is insufficient to permit such Lender to lend
its ratable share of any Borrowing requested to be made hereunder, the Borrower
shall repay such Lender's outstanding Money Market Loans simultaneously with or
prior to such Borrowing (which repayment may be financed with proceeds of such
Advances and shall be subject to the provisions of Section 3.5.8) by the amount
necessary to increase the availability under its Revolving Loan Commitment
(before giving effect to such Borrowing, but after giving effect to the
application of the proceeds thereof and to any Money Market Reduction in effect
after such application) to be at least equal to its ratable share of any such
Borrowing.

         3.5.8 Notwithstanding anything to the contrary contained herein, the
following provision shall apply to all Money Market Loans unless expressly
otherwise excluded in the terms thereof. If any payment of principal of any
Money Market Loan is made other than on the maturity date of such Money Market
Loan, as a result of the acceleration of the maturity thereof pursuant to
Section 3.5.5 or for any other reason whatsoever, the Borrower shall, upon
demand by the applicable Lender (with a copy of such demand to the
Administrative Agent), pay directly to such Lender as it may direct any amounts
required to compensate such Lender for any losses, costs or expenses which it
may reasonably incur as a result of such payment, including, without limitation,
any loss, cost or expense incurred by reason of the liquidation or redeployment
of deposits or other funds acquired by such Lender to fund or maintain such
Money Market Loan.

         3.5.9 Notwithstanding anything to the contrary contained herein, Money
Market Loans shall be deemed not to be extensions of credit, Advances or
Borrowings under this Agreement; provided that Money Market Loans shall be
considered to be extensions of credit under this Agreement for purposes of
calculating the Money Market Reduction.

         3.5.10 Notwithstanding anything to the contrary contained herein, the
Administrative Agent shall have no responsibility whatsoever for Money Market
Loans, either before or after default hereunder or thereunder, including,
without limitation, for establishing the terms thereof, declaring defaults
thereunder, monitoring compliance by the Borrower therewith or verifying
payments or repayments thereunder, and to the extent that any Lender entering
into a Money Market Loan requires any additional documentation in connection
therewith, such documentation shall be entirely the responsibility of such
Lender, including without limitation the preparation, execution, delivery and
safe-keeping thereof.

         3.5.11 Unless the Borrower shall have previously given the
Administrative Agent written notice of all then outstanding (or committed to be
advanced on or prior to the Business Day of the proposed Borrowing) Money Market
Loans (which notice shall be in writing and shall specify the applicable Lender
which had advanced a Money Market Loan, the principal amount thereof and the
borrowing date and scheduled repayment date thereof), each Notice of Borrowing
or Notice of Bid Borrowing, as the case may be, given hereunder shall also
specify such information.

3.6      Notice Provisions

         3.6.1 For each Borrowing, each optional repayment and each conversion,
the Administrative Agent shall have received prior to 11:00 a.m (Montreal time)
from the Borrower in writing a Notice of Borrowing, a Notice of Optional
Repayment or a Notice of Conversion, as the case may be, in accordance with the
following:

         (a) at least one (1) Business Day prior to the Drawdown Date or
Conversion Date, as the case may be, for each Borrowing or conversion by way of
US Base Rate Advance;

         (b) at least three (3) Business Days prior to the Drawdown Date or
Conversion Date, as the case may be, for each Borrowing or conversion by way of
Libor Advance (provided, however, that with respect to Libor Advances to be made
on the Initial Funding Date, the Borrower shall be required to deliver the
relevant Notice of Borrowing no later than 9:00 a.m. (Montreal time) two (2)
Business Days prior to the Initial Funding Date); and

         (c) at least three (3) Business Days prior to the Optional Repayment
Date for each optional repayment.

         3.6.2 If the Borrower gives a Notice of Borrowing to the Administrative
Agent in accordance with Section 3.6.1, the Administrative Agent shall on the
same day it receives such Notice of Borrowing notify each Lender by telecopier
of the particulars of such request for a Borrowing and of such Lender's
Participation in the proposed Borrowing and each Lender shall, no later than
2:00 p.m. (Montreal time) on the Drawdown Date, make or procure to be made its
Participation in the Borrowing available to the Administrative Agent.

3.7      Pro Rata Treatment

         Except in respect of Bid Loans, the Borrower agrees to request each
Borrowing from the Lenders pro rata in all respects according to their
respective Commitments and the Lenders agree to make each Borrowing available to
the Borrower pro rata in all respects according to their respective Commitments.
A Lender shall not be responsible for the Commitments of any other Lender.
Without prejudice to the rights of the Borrower against a defaulting Lender, the
failure or incapacity of a Lender to make available its Participation in a
Borrowing to the Borrower in accordance with its obligations under this
Agreement does not release the other Lenders from their obligations.

3.8      Accounts Kept by the Administrative Agent

         The Administrative Agent shall keep in its books, accounts for the Loan
and other amounts payable by the Borrower under this Agreement. The
Administrative Agent shall keep appropriate registers showing, the amount of the
indebtedness of the Borrower in respect of the Loan and showing each payment or
repayment of principal and interest made in respect of such indebtedness. Such
registers shall constitute (in the absence of manifest error) prima facie
evidence of their content against the Borrower, the Guarantors and the Lenders;
provided that the obligation of the Borrower and the Guarantors to pay or repay
any indebtedness and liability in accordance with the terms and conditions of
this Agreement shall not be affected by the failure of the Administrative Agent
to keep such registers. The Administrative Agent shall supply any Lender and the
Borrower, on demand, with copies of such registers.

3.9      Accounts Kept by each Lender

         Each Lender shall keep in its books, in respect of its Participation,
accounts for the Loan, any Bid Loans and Money Market Loans made by it, and
other amounts payable by the Borrower to it under this Agreement. Each Lender
shall make appropriate entries showing, as debits, the amount of the
indebtedness of the Borrower towards it in respect of the Loan, any such Bid
Loan or Money Market Loan, the amount of all accrued interest and any other
amount due to such Lender pursuant hereto and, as credits, each payment or
repayment of principal and interest made in respect of such indebtedness as well
as other amount paid to such Lender pursuant hereto. These accounts shall
constitute (in the absence of manifest error or of contradictory entries in the
accounts of the Administrative Agent referred in Section 3.8) prima facie
evidence of their content against the Borrower and the Guarantors.


                                    ARTICLE 4

                       REPAYMENT, CONVERSION AND REDUCTION

4.1      Mandatory Repayment and Prepayment of the Loan

         4.1.1 The Borrower covenants and agrees that it shall repay the Term
Loans made to it to the Administrative Agent for the account of the Lenders on
the Term Loan Maturity Date together with all unpaid interest accrued thereon or
owing pursuant thereto. The Borrower covenants and agrees that it shall repay
the Revolving Loans made to it to the Administrative Agent for the account of
the Lenders on the Revolving Loan Commitment Termination Date together with all
unpaid interest accrued and other amounts owing and unpaid hereunder or pursuant
hereto.

         4.1.2 The Company and the Borrower further covenant and agree that, no
later than the fifth Business Day following the date of receipt by the Company
or any of its Subsidiaries of any Net Asset Sale Proceeds in respect of any
Asset Sale consummated prior to the STB Approval Date, the Company and the
Borrower shall, and Company shall cause each borrower under the Canadian Credit
Agreement to, subject to Section 4.1.3, prepay the Term Loans, the Revolving
Loans, the Canadian Term Loans and the Canadian Revolving Loans in an aggregate
amount equal to such Net Asset Sale Proceeds (rounded downwards to the next
lowest multiple of US$100,000); provided, however, that the Company and the
Borrower shall not be required to repay any such Net Asset Sale Proceeds until
the aggregate amount thereof not yet applied to the repayment of the Term Loans,
Revolving Loans, Canadian Term Loans and Canadian Revolving Loans pursuant to
Section 4.1.3 exceeds US$10,000,000, at which time the Company and the Borrower
shall be obligated to repay (or cause each borrower under the Canadian Credit
Agreement to repay, as the case may be) all such Net Asset Sale Proceeds in
accordance with this Section as if the Company and its Subsidiaries had received
such amounts at such time; provided that, if the amount of any prepayment to the
Term Loans or Revolving Loans to be made by the Borrower pursuant to this
Section 4.1.2 exceeds the aggregate principal amount of that portion of the Loan
bearing interest at a rate determined by reference to the US Base Rate, the
Borrower shall place and maintain with the Administrative Agent an interest
bearing deposit in the amount of such excess amount pending application of such
amounts on deposit (it being understood that the Borrower, other than upon the
occurrence and during the continuance of an Event of Default, may direct the
Administrative Agent to invest such amounts on deposit in cash equivalents) from
time to time as soon as practicable thereafter to repay Term Loans or Revolving
Loans, respectively, consisting of US Base Rate Loans or other Advances to the
Borrower, which application shall be made in a manner which does not require
additional payments by the Borrower pursuant to Section 9.9.4.

         4.1.3 Any prepayments made pursuant to Section 4.1.2 shall be made
without premium or penalty and shall be applied first, to the prepayment of the
Term Loans and the Canadian Term Loans pro rata according to the respective
outstanding principal amount, if any, of each and to the full extent thereof,
and second, to the prepayment of the Revolving Loans and the Canadian Revolving
Loans pro rata according to the respective outstanding principal amount, if any,
of each and to the full extent thereof; provided that prepayments of the
Revolving Loans shall not be required pursuant to Section 4.1.2 or this Section
4.1.3 if on the date the relevant Net Asset Sale Proceeds are received by the
Company or any of its Subsidiaries (i) the Company's Public Debt Rating by S&P
is BBB or higher or the Company's Public Debt Rating by Moody's is Baa2 or
higher and (ii) the aggregate Revolving Loan Commitments and the commitments
under the Canadian Credit Agreement to make Canadian Revolving Loans are not
greater than US$700,000,000.

4.2      Optional Repayments

         4.2.1 At any time prior to the Revolving Loan Commitment Termination
Date, subject to Section 4.4, the Borrower may elect to repay by a Notice of
Optional Repayment received by the Administrative Agent, and on the Optional
Repayment Date set forth therein the Borrower shall repay, to the Administrative
Agent for the account of the Lenders, all or part of the Borrowings under the
Credit with interest accrued thereon to the date of such repayment. Within the
limits of each Lender's Revolving Loan Commitment and subject to the terms of
this Agreement, the Borrower may reborrow any Revolving Loans so repaid. Any
optional repayments pursuant to this Section 4.2 shall be applied as specified
by the Borrower in the applicable Notice of Optional Prepayment; provided that
in the event the Borrower fails to specify the Loans to which any such
prepayment shall be applied, such prepayment shall be applied first to repay
outstanding Revolving Loans to the full extent thereof, and applied pro rata in
proportion to the amount of Revolving Loans made to the Borrower, and second to
repay outstanding Term Loans to the full extent thereof. Notwithstanding
anything in this Agreement to the contrary, the Borrower shall not make any
optional prepayment of all or a portion of the outstanding Term Loans unless a
ratable portion of the Canadian Term Loans outstanding at the time of such
prepayment are also prepaid concurrently therewith.

         4.2.2 Subject to compliance with Section 4.2.1, prepayments may be made
without premium or penalty.

         4.2.3 All optional repayments are in addition to and not in replacement
of mandatory repayments provided for in Section 4.1.1.

         4.2.4 Notwithstanding the foregoing, a Borrowing outstanding by way of
Letter of Credit may only be repaid or discharged prior to the expiry date of
the Letter of Credit by:

         (a) the Administrative Agent being fully released and discharged of all
         its liabilities and obligations arising from such Letter of Credit and
         by written evidence satisfactory to the Administrative Agent of such
         full release and discharge being delivered to the Administrative Agent;
         or

         (b) by way of the issue to the Administrative Agent by a financial
         institution acceptable to the Administrative Agent, in its sole
         discretion, of a full, unconditional counter-guarantee or indemnity in
         favor of the Administrative Agent acceptable to the Administrative
         Agent in respect of such Letter of Credit.

4.3      Conversion Option

         4.3.1 At any time prior to the Term Loan Maturity Date or the Revolving
Loan Commitment Termination Date, respectively, subject to Section 4.4, the
Borrower may elect to convert by Notice of Conversion received by the
Administrative Agent, and on the Conversion Date set forth therein the Borrower
shall convert, any basis of funding (other than Letters of Credit) of all or any
portion of the Borrowings consisting of Term Loans and/or the Borrowings
consisting of Revolving Loans, respectively (each a "Converted Advance"), into
another basis of funding (each a "Conversion Advance"); provided that the
Borrower may convert the basis of funding of any Borrowings only into another
basis that the Borrower is permitted to select for such Borrowings under Section
3.1 or 3.2. The provisions of this Agreement relating to Libor Advances shall
apply mutatis mutandis to Conversion Advances comprising Libor Advances.

         4.3.2 If on any date an Advance is outstanding with respect to which
notice has not been delivered to the Administrative Agent specifying the
applicable basis for determining the rate of interest, then for that day that
Advance shall bear interest by reference to the US Base Rate.

4.4      Requirements for Optional Repayments and Optional Conversions

         Each optional repayment pursuant to Section 4.2 or conversion pursuant
to Section 4.3 shall be subject to the following terms and conditions:

         4.4.1 each repayment or conversion shall be in a minimum amount of
US$10,000,000 or such larger amount as is an integral multiple of US$1,000,000
(or, for repayments, the remaining balance of the Borrowings if less than such
minimum amount), and shall be made on a Business Day specified in the Notice of
Optional Repayment or Notice of Conversion;

         4.4.2 the Borrower shall have given the Administrative Agent notice in
accordance with Section 3.6 for each repayment and each conversion, each notice
stating the proposed date of the repayment or conversion and either the
aggregate principal amount of the repayment or the aggregate principal amount of
the Converted Advance and the type of Conversion Advance;

         4.4.3 if a Notice of Optional Repayment is given, it shall be
irrevocable and binding on the Borrower and the Borrower shall repay on the
Optional Repayment Date specified in such notice in USDollars the amount stated
in such notice with accrued interest to the date of such repayment; and if a
Notice of Conversion is given it shall be irrevocable and binding on the
Borrower; and

         4.4.4 should any such repayment or conversion result in the repayment
of or conversion from any Libor Loan Portion on a day other than the last day of
its then current Interest Period, the Borrower shall, in addition, pay to the
Administrative Agent the amount calculated as set forth in Section 9.9.4.

4.5      Authority to Debit

         In respect of all amounts payable by the Borrower under this Agreement,
the Borrower hereby irrevocably authorizes and instructs the Administrative
Agent to withdraw from or debit, from time to time when such amounts are due and
payable, any account of the Borrower listed in Schedule 4.5 annexed hereto (as
such Schedule 4.5 may be amended from time to time as agreed between the
Borrower and the Administrative Agent) for the purpose of satisfying payment
thereof.

4.6      Reduction of the Commitments

         4.6.1 The Borrower may, upon at least five (5) Business Days' notice to
the Administrative Agent, terminate in whole or reduce ratably in part (without
premium or penalty) the unused portions of the Commitments of the Lenders;
provided that each partial reduction shall be in the aggregate amount of
US$25,000,000 or an integral multiple of US$5,000,000 in excess of
US$25,000,000. In any such notice, the Borrower must state the proposed date and
aggregate principal amount of the reduction and, if such notice is given, the
Borrower shall pay the Administrative Agent in accordance with such notice the
amount, if any, by which the Total Utilization of Revolving Loan Commitments
(after giving effect to any Money Market Reduction) exceeds the proposed reduced
aggregate Revolving Loan Commitments and the Borrower shall pay at the same time
all interest and other amounts owing in respect of such excess amount accrued to
the date of such reduction. Should any such payment result in the payment of any
Libor Loan Portion on a day other than the last day of its then current interest
period, the Borrower shall, in addition, pay to the Administrative Agent for the
benefit of the applicable Lenders the amount calculated as set forth in Section
9.9.4.

         4.6.2 On each date that the Revolving Loans are required to be prepaid
pursuant to Section 4.1.2, the Revolving Loan Commitments shall be permanently
reduced in the amount of such required prepayment.

4.7      Increase of Revolving Loan Commitment

         The Borrower may, from time to time, request an increase of each
Lender's Revolving Loan Commitment by giving written notice to the
Administrative Agent making such request and specifying the date upon which the
Borrower requests that such increase come into effect (the "Effective Date") and
detailing the amount by which each Lender's Revolving Loan Commitment shall be
increased; such notice shall be given by the Borrower between the 90th and 60th
days prior to the Effective Date. The Administrative Agent shall promptly
forward a copy of such request to the Lenders and each Lender shall notify the
Administrative Agent within 30 days of the Borrower's request whether such
Lender is willing to grant such an increase. In the event that a Lender has
failed to notify the Administrative Agent within such 30 day period of whether
it has elected to increase its Revolving Loan Commitment, such Lender shall be
deemed not to have elected to increase its Revolving Loan Commitment. Each
increase request shall be considered by each Lender, in its sole discretion, and
each Lender shall not, under any circumstances, be obliged to approve or accept
any increase request. The Administrative Agent shall promptly notify the
Borrower and the Lenders which Lenders have elected to increase their respective
Revolving Loan Commitments. In the event that a Lender elects to increase its
Revolving Loan Commitment then (regardless of whether any other Lender has
elected to so increase but provided there is no increase in the Total Commitment
unless all the Lenders and all lenders designated as "Lenders" under the
Canadian Credit Agreement have agreed thereto) the Revolving Loan Commitment for
such Lender shall be increased by the amount of the increase requested by the
Borrower and agreed to by such Lender.

         If a Lender elects or is deemed to have elected not to increase its
Revolving Loan Commitment, the Lenders who have elected to increase their
Revolving Loan Commitments shall have the option (all such Lenders who elect to
exercise such option being "Accepting Lenders") to take up on a pro rata basis
the dissenting Lenders' portion of the increase by so advising the
Administrative Agent. The Administrative Agent shall allocate amongst the
Accepting Lenders the amount of the Revolving Loan Commitment available from
each dissenting Lender in its discretion but always on a pro rata basis or as
nearly pro rata as shall be practical.

         If the Accepting Lenders do not take up all of the dissenting Lenders'
portion of the increase (on a pro rata basis or otherwise), the Borrower may, at
its option (and at any time prior to or on the applicable Effective Date) offer
such portion to one or more financial institutions, provided that such other
financial institutions are acceptable to the Administrative Agent and provided
such offer is consummated as soon as possible to the satisfaction of the
Administrative Agent. The provisions in Section 15.14 dealing with Dissenting
Lenders shall not apply to a dissenting Lender under this Section 4.7.


                                    ARTICLE 5

                                INTEREST AND FEES

5.1      Interest

         The Borrowings shall bear interest from the date of each Advance,
calculated on a daily basis and payable in arrears, on the US Base Rate Loan at
the US Base Rate, and on each Libor Loan Portion at LIBOR plus the Applicable
Margin in effect from time to time for such Libor Loan Portion for the then
current Interest Period, and all overdue amounts shall bear interest in
accordance with Section 5.5. All outstanding amounts shall bear interest both
before and after default and before and after judgment at the rates determined
as aforesaid.

5.2      Payment of Interest on Libor Loan

         On each Interest Payment Date in respect of each Libor Loan Portion of
a Lender, the Borrower shall pay the Administrative Agent interest on such Libor
Loan Portion at the rate per annum determined by the Administrative Agent to be
LIBOR in respect of such Libor Loan Portion for the applicable Interest Period
plus the Applicable Margin in effect from time to time during such Interest
Period. Upon determination of the applicable rate of interest on any Libor Loan
Portion, the Administrative Agent shall notify the Borrower of this rate. The
Administrative Agent will compute the interest on the basis of the actual number
of days elapsed in the period for which such interest is payable divided by
three hundred and sixty (360).

5.3      Payment of Interest on US Base Rate Loan

         On each Interest Payment Date in respect of the US Base Rate Loan, the
Borrower shall pay the Administrative Agent interest on the US Base Rate Loan at
the US Base Rate. The Borrower will pay this interest in arrears for the period
up to but excluding such Interest Payment Date; the Administrative Agent will
compute the interest on the basis of the actual number of days elapsed in the
period for which such interest is payable divided by the actual number of days
of the year. Each change in the fluctuating interest rate for the US Base Rate
Loan will take place simultaneously with the corresponding change in the US Base
Rate.

5.4      Selection of Interest Periods

         In each Notice of Borrowing delivered pursuant to Section 3.3 and each
Notice of Conversion delivered pursuant to Section 4.3 in which the Borrower has
elected a Borrowing or Conversion Advance comprising a Libor Loan Portion and at
least three Business Days prior to the last day of each Interest Period in
respect of each Libor Loan Portion, the Borrower shall select and notify the
Administrative Agent of the Interest Period applicable to such Libor Loan
Portion commencing on the Drawdown Date, Conversion Date or last day of the
Interest Period, as the case may be, and ending on a Business Day, which period
shall be one (1) month, two (2) months, three (3) months, six (6) months or,
subject to availability, nine (9) months or twelve (12) months, as the Borrower
may elect; provided, however, that:

         5.4.1 if the Borrower fails to so elect the duration of any Interest
Period, the amount of such Libor Loan Portion shall be deemed to be a US Base
Rate Advance at the end of the current Interest Period and interest thereon
shall be payable at the US Base Rate; and

         5.4.2 the amount in respect of which the Borrower selects an Interest
Period shall not be less than ten million USDollars (US$10,000,000) and in
integral multiples of one million USDollars (US$1,000,000) in excess thereof.

5.5      Default Interest

         If the Borrower defaults in any payment of principal, interest or any
other amount due pursuant to this Agreement, the Borrower shall pay to the
Administrative Agent on demand interest on such overdue principal, overdue
interest and other overdue amount, from the date the amount is due until the
date it is paid in full, and all interest on overdue principal, all overdue
interest and all interest on overdue interest shall be compounded monthly, at
the rates per annum as follows:

         5.5.1 with respect to the Libor Loan and any Libor Advance to the
Borrower the Borrower shall be deemed to have elected that any amount of
principal of the Libor Loan or any Libor Loan Portion or Libor Advance which is
not paid when due shall thereupon cease to be a Libor Loan or Libor Advance and
shall be a US Base Rate Advance, and the Borrower shall pay interest on all such
overdue principal and any overdue interest and interest on interest thereon at a
fluctuating rate per annum at all times equal to the US Base Rate plus two
percent (2%) per annum; and

         5.5.2 on overdue principal of, and overdue interest on, the US Base
Rate Loan, and on any other amounts owing, at a fluctuating rate per annum at
all times equal to the US Base Rate plus two percent (2%) per annum.

5.6      Determination of Interest Rates

         5.6.1 Each Reference Lender, at the request of the Administrative
Agent, agrees to furnish to the Administrative Agent timely information for the
purpose of determining each US Base Rate and each LIBOR. If any one or more of
the Reference Lenders shall not furnish such timely information to the
Administrative Agent for the purpose of determining any such interest rate or
fee, the Administrative Agent shall determine such interest rate or fee on the
basis of timely information furnished by the remaining Reference Lenders.

         5.6.2 Each determination by the Administrative Agent from time to time

Guarantors and the Lenders.

5.8      Facility Fee

         The Borrower shall pay to the Administrative Agent, for the account of

such Lender's Term Loan Commitment and (y) on and after the Initial Funding

equal to the Facility Fee in effect from time to time during the period for
which such payment is made, payable in arrears on the last day of each March,

                                    ARTICLE 7

                                LETTERS OF CREDIT

7.1      Letter of Credit Commitment

         Subject to the terms and conditions hereof, the Administrative Agent,
on behalf of the Lenders, and in reliance on the agreements of the Lenders set
forth in Section 7.2, agrees to issue for the account of the Borrower Letters of
Credit in USDollars from time to time on any Business Day during the period from
the date hereof until the date occurring one month prior to the Revolving Loan
Commitment Termination Date; provided that (a) the Letter of Credit Exposure
shall not at any time exceed US$80,000,000, (b) the Borrower shall not request
the issuance of any Letter of Credit if, after giving effect to such issuance,
the Total Utilization of Revolving Loan Commitments (after giving effect to any
Money Market Reduction) would exceed the aggregate Revolving Loan Commitments
and (c) the Borrower shall not request the issuance of, and the Administrative
Agent shall not issue, any Letter of Credit having an expiration date later than
the Revolving Loan Commitment Termination Date.

7.2      Letter of Credit Participations

         The Administrative Agent irrevocably grants, and in order to induce the
Administrative Agent to issue its Letters of Credit for the account of the
Borrower hereunder, each Lender irrevocably accepts and hereby purchases from
the Administrative Agent, on the terms and conditions hereinafter stated, for
its own account and risk an undivided interest equal to such Lender's
Participation in the Administrative Agent's obligations and rights under each
Letter of Credit issued hereunder for the account of the Borrower and the amount
of each draft paid by the Administrative Agent thereunder. Each Lender
unconditionally and irrevocably agrees with the Administrative Agent that, on or
before the close of business of the Administrative Agent, on each day on which a
draft is paid under a Letter of Credit issued for the account of the Borrower
for which the Administrative Agent is not reimbursed in full by the Borrower in
accordance with the terms of this Agreement, including, without limitation,
pursuant to Section 7.8.1 (a "Lender Participation Date"), such Lender will pay
to the Administrative Agent for the account of the Administrative Agent at the
Administrative Agent's office specified in Section 9.1 such Lender's
Participation of any unpaid Reimbursement Obligation. The Administrative Agent
shall notify each Lender of the occurrence of a Lender Participation Date, and
the amount payable by it to the Administrative Agent based on such Lender's
Participation. Any such notice may be oral if promptly confirmed in writing
(including telecopy). If any Lender fails to make any such payment on or prior
to the first Business Day after such Lender receives notice as provided above,
then interest shall accrue on such Lender's obligation to make such payment
during the period from such Business Day to the day such Lender makes such
payment (or if earlier, the date on which the Borrower reimburses the
Administrative Agent for such unpaid Reimbursement Obligation) at the rate
specified in Section 15.6.2.

7.3      Repayment of Participants

         Upon and only upon receipt by the Administrative Agent of funds from
the Borrower in full or partial reimbursement of any draft paid under a Letter
of Credit with respect to which any Lender has theretofore paid the
Administrative Agent for the account of the Administrative Agent in full for
such Lender's participation pursuant to Section 7.2 and in full or partial
payment of interest, commissions or fees on such draft paid under a Letter of
Credit, the Administrative Agent will pay to such Lender, in the same funds as
those received by the Administrative Agent, or net against any then due
obligation of such Lender under Section 7.2 to make any payment to the
Administrative Agent, such Lender's Participation of such funds.

7.4      Role of the Administrative Agent

         The Administrative Agent will exercise and give the same care and
attention to each Letter of Credit as it gives to its other letters of credit
and similar obligations, and the Administrative Agent's sole liability to each
Lender shall be to distribute promptly, as and when received by the
Administrative Agent, each Lender's Participation of any payments made to the
Administrative Agent by the Borrower pursuant to Section 7.2. Each Lender agrees
that, in paying any drawing under a Letter of Credit, the Administrative Agent
shall not have any responsibility to obtain any document (other than as required
by such Letter of Credit) or to ascertain or inquire as to the validity or
accuracy of any such document or the authority of any Person delivering any such
document. Neither the Administrative Agent nor any of its representatives,
officers, employees or agents shall be liable to any Lender for (a) any action
taken or omitted to be taken in connection herewith at the request or with the
approval of the Majority Lenders, (b) any action taken or omitted to be taken in
the absence of gross negligence or wilful misconduct, (c) any recitals,
statements, representations or warranties contained in any document distributed
to any Lender, (d) the creditworthiness of the Borrower, or (e) the execution,
effectiveness, genuineness, validity, or enforceability of any Letter of Credit,
or any other document contemplated thereby. The Administrative Agent shall not
incur any liability (i) by acting in reliance upon any notice, consent,
certificate, statement or other writing (which may be a bank wire, telex or
similar writing) believed by it to be genuine or to be signed by the proper
party or parties or (ii) by acting as permitted under Section 7.14. The
obligations of the Lenders hereunder are several, and no Lender shall be liable
for the performance or non-performance of the obligations of any other Lender
under this Article 7.

7.5      Lenders' Obligations Absolute

         Each Lender acknowledges that its obligations to the Administrative
Agent under this Article 7, including the obligation to purchase and fund a
participation in the obligations and rights of the Administrative Agent under
each Letter of Credit and any unpaid Reimbursement Obligation, is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including, without limitation, (i) the occurrence and continuance of an Event of
Default or an event which, with the giving of notice or the passage of time, or
both, would constitute an Event of Default, (ii) subject to the next sentence of
this Section 7.5, the fact that a condition precedent to the issuance of any
Letter of Credit was not in fact satisfied, (iii) any failure or inability of
any other Lender to purchase or fund such a participation hereunder, or (iv) any
other failure by any other Lender to fulfil its obligations hereunder. Without
affecting the rights and remedies of the Administrative Agent and the Lenders
with respect to the Borrower in the event of any such condition precedent is not
in fact satisfied, each Lender authorizes the Administrative Agent in its sole
discretion and on behalf of such Lender (but without obligating the
Administrative Agent), without further notice to such Lender so long as the
Administrative Agent shall have notified the Lenders two Business Days prior to
the day of issuance that such condition precedent is not or will not be
satisfied, to waive any condition precedent set forth in Article 10 to the
issuance of the Letter of Credit (or deem each such condition precedent
satisfied) in connection with each issuance of the Letters of Credit unless the
Administrative Agent shall have received by the close of its business, Montreal
time, on the Business Day immediately preceding the day of such issuance written
instructions from the Majority Lenders not to waive such condition precedent and
such written instructions have not been withdrawn by the Majority Lenders. Each
payment by a Lender to the Administrative Agent for its own account shall be
made, without any offset, compensation, abatement, withholding or reduction
whatsoever.

7.6      Reinstatement and Survival

         Notwithstanding anything herein to the contrary, if the Administrative
Agent is required at any time whether before or after the Revolving Loan
Commitment Termination Date to make any payment under a Letter of Credit which
was outstanding on or before the Revolving Loan Commitment Termination Date,
each Lender shall pay over to the Administrative Agent, in accordance with the
provisions of this Article 7, the amount of such Lender's Participation of such
amount. If the Administrative Agent is required at any time (whether before or
after the Revolving Loan Commitment Termination Date) to return to the Borrower
or to a trustee, receiver, liquidator, custodian or other similar official any
portion of the payments made by or on behalf of the Borrower to the
Administrative Agent in reimbursement of Reimbursement Obligations and interest
thereon, each Lender shall, on demand of the Administrative Agent, forthwith pay
over to the Administrative Agent for its account such Lender's Participation of
such amount, plus interest thereon from the day such demand is made to the day
such amount is returned by such Lender to the Administrative Agent at the rate
specified in Section 15.6.2.

7.7      Procedure for Issuance and Renewal of Letters of Credit

         7.7.1 The Borrower may request the Administrative Agent to issue a
Commercial Letter of Credit in favor of a seller of goods to the Borrower, by
delivering to the Administrative Agent at its office specified in Section 9.1 a
commercial letter of credit application on the Administrative Agent's then
customary form (as such form may be modified from time to time, the "Commercial
Letter of Credit Applications"), completed to the satisfaction of the
Administrative Agent, together with the proposed form of such Commercial Letter
of Credit (which shall comply with the applicable requirements set forth herein)
and such other certificates, documents and other papers and information as the
Administrative Agent may reasonably request; provided that in the event of a
conflict between this Agreement and the Commercial Letter of Credit Application,
this Agreement shall govern with respect to such conflict.

         7.7.2 The Borrower may request the Administrative Agent to issue a
Standby Letter of Credit by delivering to the Administrative Agent at its office
specified in Section 9.1 a standby letter of credit application on the
Administrative Agent's then customary form (as such form may be modified from
time to time, the "Standby Letter of Credit Application"), completed to the
satisfaction of the Administrative Agent, together with the proposed form of
such Standby Letter of Credit (which shall comply with the applicable
requirements set forth herein) and such other certificates, documents and other
papers and information as the Administrative Agent may reasonably request;
provided that in the event of a conflict between this Agreement and the Standby
Letter of Credit Application, this Agreement shall govern with respect to such
conflict.

         7.7.3 Within three (3) Business Days following the date on which the
Administrative Agent shall have received an application for the issuance of a
Letter of Credit including the form thereof, and such additional certificates,
documents and other papers and information as the Administrative Agent may have
reasonably requested in satisfaction of all conditions to the issuance thereof,
the Administrative Agent shall, provided the conditions of Article 10 have been
complied with, issue such Letter of Credit (if the Borrower shall have requested
that such Letter of Credit be issued immediately) or (if the Borrower shall have
requested in the related Commercial Letter of Credit Application or Standby
Letter of Credit Application that such Letter of Credit be issued at a later
date) the Administrative Agent shall notify the Borrower that the Administrative
Agent shall, provided the conditions of Article 10 have been complied with,
issue such Letter of Credit on such later date, or that the Administrative Agent
shall not issue such Letter of Credit by reason of a provision set forth herein.

         7.7.4 The Borrower may request the extension or renewal of a Letter of
Credit issued hereunder which is not automatically renewed in accordance with
the terms contained therein, by giving written notice to the Administrative
Agent at least three (3) Business Days prior to the then current expiry date of
such Letter of Credit (provided that the Administrative Agent may accommodate
notices on shorter notice in its sole discretion). If the conditions precedent
in Section 10.2 shall have been fulfilled as required thereby, the
Administrative Agent shall promptly issue such extension or renewal.

         7.7.5 With respect to any Letter of Credit issued hereunder which by
its terms is automatically renewed or extended unless notice to the contrary is
received by the beneficiary thereunder within the time period set forth therein
(the "Revocation Period"), the Administrative Agent shall, upon receipt of
notice from the Majority Lenders (which notice must be received by the
Administrative Agent not later than 10:00 A.M. (Montreal time) ten (10) Business
Days prior to the expiration of the Revocation Period so long as the
Administrative Agent shall have notified the Lenders of such renewal or
extension at least one Business Day prior to such date), to the effect that the
Majority Lenders have elected not to extend the current expiry date of such
Letter of Credit, promptly notify the Borrower and the beneficiary thereunder
that such Letter of Credit shall not be renewed.

         7.7.6 Notwithstanding anything to the contrary in this Agreement, the
Administrative Agent shall have no obligation to extend or renew any Letter of
Credit issued hereunder to a maturity date extending beyond the Revolving Loan
Commitment Termination Date, and each Lender shall have no obligation to
purchase a participation in the Administrative Agent's obligations and rights
under any Letter of Credit extended or renewed to a date beyond the Revolving
Loan Commitment Termination Date.

7.8      Reimbursement of the Administrative Agent

         7.8.1 In the event that any drawing shall be made under any Letter of
Credit, and if no Event of Default shall have occurred and be continuing, (i)
the Administrative Agent shall promptly notify the Borrower of such payment and
of the amount thereof, (ii) the payment by the Administrative Agent of such
drawing shall constitute the making of a US Base Rate Advance to the Borrower by
the Lenders according to their respective Participation and the Borrower shall
be deemed to have elected to denominate same in USDollars and pay interest
thereon at the US Base Rate, and (iii) immediately upon receipt of such notice,
each Lender shall make its Participation, available to the Administrative Agent
by wire transfer of immediately available funds to the office of the
Administrative Agent specified in Section 9.1.

         7.8.2 In the event that a drawing shall be made under any Letter of
Credit and an Event of Default shall have occurred, no US Base Rate Advance
shall be deemed to have been made in respect of such drawing and the Borrower
(i) shall reimburse the Administrative Agent for the amount paid on each draft
drawn under each Letter of Credit not later than the close of business on the
first Business Day following the day on which the Borrower receives notice of
such drawing, and (ii) shall pay, (A) all charges and expenses relating to such
drawing as may be payable in accordance with Section 7.9 and (B) interest at the
rate specified in Section 7.10 on the amount of such drawing for the period
commencing on the date of any such payment and ending on the date reimbursement
is received by the Administrative Agent.

7.9      Commissions, Fees and Charges

         7.9.1 The Borrower agrees to pay for each Letter of Credit, to (A) the
Administrative Agent (solely for its account) a non-refundable fronting fee with
respect to each Letter of Credit, in an amount equal to 1/8 of 1% per annum of
the face amount thereof, and (B) the Administrative Agent for the account of
each Lender, a non-refundable letter of credit commission, computed at a rate
equal to the Applicable Margin times such Lender's Participation of the
aggregate amount available to be drawn under such Letter of Credit, such
fronting fee and letter of credit commissions to be payable quarterly in advance
for the number of days outstanding, at the rate specified above and in the
currency of such Letter of Credit, commencing on the date of issuance of such
Letter of Credit and thereafter on the last day of each March, June, September
and December so long as such Letter of Credit shall remain outstanding.

         7.9.2 In addition to the fees referred to in Section 7.9.1, the
Borrower agrees to pay or reimburse the Administrative Agent for such normal and
customary costs and expenses as are incurred or charged by the Administrative
Agent in issuing, effecting payment under or administering any Letter of Credit
(including, without limitation, amendment fees, correspondent lender fees,
reissuance costs and cancellation fees).

         7.9.3 The Administrative Agent shall promptly distribute, at the end of
each calendar quarter, all letter of credit commissions received for the account
of each Lender by the Administrative Agent during such calendar quarter,
together with a statement from the Administrative Agent reconciling the
collection and distribution of such commissions.

7.10     Interest on Amounts Disbursed under Letters of Credit

         Subject to Section 7.8, the Borrower agrees to pay to the
Administrative Agent interest on any and all amounts disbursed by the
Administrative Agent under any Letter of Credit from the date of disbursement
until reimbursed in full at the US Base Rate. Interest accrued hereunder shall
be payable on demand. For the purposes of computing the number of days for which
interest shall accrue on amounts disbursed under Letters of Credit, payments
received by the Administrative Agent after 1:00 PM., Montreal time, shall be
deemed to have been received on the next following Business Day. All payments
(including prepayments) by the Borrower to the Administrative Agent, whether on
account of the Borrower's Reimbursement Obligation or interest thereon, on
account of any fees due hereunder or otherwise, shall be made in USDollars for
Letters of Credit in USDollars and in immediately available funds without set
off, compensation or counterclaim to the Administrative Agent.

7.11     Computation of Interest and Fees; Payment not on Business Day

         7.11.1 Interest and per annum fees due under this Article 7 shall be
computed on the basis of a year of 365 (or 366 in a leap year) days for actual
days elapsed. Any change in any interest rate hereunder resulting from a change
in the US Base Rate shall become effective as of the opening of business on the
day on which such change in the US Base Rate becomes effective.

         7.11.2 If any payment under this Article 7 becomes due and payable on a
day which is not a Business Day, the maturity thereof shall be extended to the
next succeeding Business Day, and, in the case of any amount disbursed under a
Letter of Credit, interest thereon shall be payable at the then applicable rate
during such extension.

7.12     Increased Costs

         If any change occurring after the date of this Agreement in any Law or
in the interpretation or application thereof by any Governmental Authority
charged with the administration thereof shall either (i) impose, modify, assess
or deem applicable any reserve, special deposit, assessment or similar
requirement against Letters of Credit issued by the Administrative Agent or any
Lender or (ii) impose on the Administrative Agent or any Lender any other
condition regarding any Letter of Credit, and the result of any event referred
to in clauses (i) or (ii) above shall be to increase the cost to the
Administrative Agent or such Lender of issuing or maintaining a Letter of
Credit, or its participation therein, as the case may be (which increase in cost
shall be the result of the Administrative Agent's or such Lender's reasonable
allocation of the aggregate of such cost increases resulting from such events),
then, upon demand by the Administrative Agent or such Lender, the Borrower shall
immediately pay to the Administrative Agent or such Lender, from time to time as
specified by the Administrative Agent or such Lender, additional amounts which
shall be sufficient to compensate the Administrative Agent or such Lender for
such increased cost, together with interest on each such amount from the date
demanded until payment in full thereof at the rate provided in Section 7.10. A
certificate as to the fact and amount of such increased cost incurred by the
Administrative Agent or any Lender as a result of any event mentioned in clauses
(i) or (ii) above, submitted by the Administrative Agent or any such Lender to
the Borrower, shall be conclusive, absent manifest error.

         In the event the Borrower is required to pay additional amounts as
compensation for increased cost as provided above, the Borrower shall (subject
to the terms hereof) be entitled to require (with a copy to the Administrative
Agent) the Lender to whom such additional amounts are being paid to assign to an
alternate lender in accordance with Section 16.1.7 all of such Lender's rights
and obligations hereunder and such alternate lender shall execute all such
documents as may be reasonably required by the Administrative Agent, the
Borrower and such Lender to effect such assignment provided that (i) each such
assignment shall be arranged by the Borrower (with such reasonable assistance
from such Lender as the Borrower may request) after consultation with the
Administrative Agent and shall be an assignment of all of the rights and
obligations of the assigning Lender under this Agreement, (ii) no Lender shall
be obligated to make any such assignment as a result of a demand by the Borrower
pursuant to this Section 7.12 unless and until such Lender shall have received
payment from either the Borrower or the assignee in an aggregate amount at least
equal to the aggregate outstanding principal amount of the Loan and Bid Loan and
any Money Market Loans owing to such Lender, together with accrued interest
thereon to the date of payment of such principal amount and all other amounts
payable to such Lender under this Agreement (including, without limitation,
payment of the increased costs and additional amounts demanded by such Lender
pursuant to this Section 7.12 incurred by such Lender prior to the effective
date of such assignment), and (iii) such alternate lender shall have been
approved in writing by the Administrative Agent, such approval not to be
unreasonably withheld.

7.13     Further Assurances

         The Borrower hereby agrees from time to time, to do and perform any and
all acts and to execute any and all further instruments required or reasonably
requested by the Administrative Agent more fully to effect the purposes of this
Article 7 and the issuance of the Letters of Credit hereunder.

7.14     Nature of Obligations; Indemnities

         7.14.1 The obligations of the Borrower hereunder shall be absolute and
unconditional under any and all circumstances and irrespective of any set off,
compensation, counterclaim or defense to payment which the Borrower may have or
have had against the Administrative Agent, any Lender or any beneficiary of a
Letter of Credit. The Borrower assumes all risks of the acts or omissions of the
users of the Letters of Credit and all risks of the misuse of the Letters of
Credit. Neither the Administrative Agent, any of its correspondents nor any
Lender shall be responsible: (i) for the form, validity, sufficiency, accuracy,
genuineness or legal effect of any document specified in any applications for
any of the Letters of Credit, even if it should in fact prove to be in any or
all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for
the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any of the Letters of Credit or any of the
rights or benefits thereunder or proceeds thereof in whole or in part, which may
prove to be invalid or ineffective for any reason; (iii) for failure of any
draft to bear any reference or adequate reference to any of the Letters of
Credit, or failure of anyone to note the amount of any draft on the reverse of
any of the Letters of Credit or to surrender or to take up any of the Letters of
Credit or to send forward any such document apart from drafts as required by the
terms of any of the Letters of Credit; (iv) for error, omissions, interruptions
or delays in transmission or delivery of any messages, by mail, cable,
telegraph, telex or otherwise, whether or not they be in cipher; (v) for any
error, neglect, default, suspension or insolvency of any correspondents of the
Administrative Agent; (vi) for error in translation or for errors in
interpretation of technical terms; (vii) for any loss or delay, in the
transmission or otherwise, of any such document or draft or of proceeds thereof;
or (viii) for any other circumstances whatsoever in making or failing to make
payment under a Letter of Credit; provided that in each of the circumstances
referred to in clauses (i) through (viii) above the Borrower shall have a claim
against the Administrative Agent, and the Administrative Agent shall be liable
to the Borrower, to the extent, but only to the extent, of any direct, as
opposed to consequential, damages suffered by the Borrower which the Borrower
proves were caused by the Administrative Agent's wilful misconduct or gross
negligence. None of the above shall affect, impair or prevent the vesting of any
of the rights or powers of the Administrative Agent or any of the Lenders.

         7.14.2 In furtherance and extension and not in limitation of the
specific provisions hereinabove in this Article 7 set forth, (i) any action
taken or omitted by the Administrative Agent or by any of its respective
correspondents under or in connection with any of the Letters of Credit, if
taken or omitted in good faith and without wilful misconduct or gross
negligence, shall be binding upon the Borrower and shall not put the
Administrative Agent or its respective correspondents under any resulting
liability to the Borrower and (ii) the Administrative Agent may, without wilful
misconduct or gross negligence, accept documents that appear on their face to be
in order, without responsibility for further investigation, regardless of any
notice or information to the contrary; provided, that if the Administrative
Agent shall receive written notification from both the beneficiary of a Letter
of Credit and the Borrower that sufficiently identifies (in the opinion of the
Administrative Agent) documents to be presented to the Administrative Agent
which are not to be honored, the Administrative Agent agrees that it will not
honor such documents.

         7.14.3 The Borrower hereby agrees at all times to protect, indemnify
and save harmless the Administrative Agent and each Lender participating in a
Letter of Credit, from and against any and all claims, actions, suits and other
legal proceedings, and from and against any and all losses, claims, demands,
liabilities and damages, which they or any of them may, at any time, sustain or
incur by reason of or in consequence of or arising out of the issuance of any of
the Letters of Credit (all of the foregoing, collectively, the "indemnified
liabilities"), it being the intention of the parties that this Agreement shall
be construed and applied to protect and indemnify each of the Administrative
Agent and each Lender participating in a Letter of Credit against any and all
risks involved in the issuance of all of the Letters of Credit, all of which
risks, whether or not foreseeable, being hereby assumed by the Borrower,
including, without limitation, any and all risks of all acts by any Governmental
Authority and any and all claims by correspondents used in connection with a
Letter of Credit, provided that the Borrower shall not have any obligation
hereunder to an indemnified party with respect to indemnified liabilities
arising from the gross negligence or wilful misconduct of such indemnified
party. Neither the Administrative Agent nor any Lender shall, in any way, be
liable for any failure by it or anyone else to pay a draft drawn under any of
the Letters of Credit as a result of any acts, whether rightful or wrongful, of
any Governmental Authority or any correspondent used in connection with a Letter
of Credit or any other cause not readily within their control or the control of
their respective correspondents. Without limiting the generality of the
foregoing, the Borrower shall be responsible for, and shall reimburse the
Administrative Agent forthwith upon its receipt of any demand therefor, any and
all commissions, fees and other charges paid or payable by the Administrative
Agent to any foreign lender which shall be an advising lender or a beneficiary
of a Letter of Credit which shall, in reliance thereon, have issued its own
letter of credit in respect of obligations of the Borrower.

7.15     Payments upon any Event of Default

         The Borrower agrees that upon the occurrence and during the continuance
of any Event of Default, in addition to all other rights and remedies, the
Administrative Agent shall at the request, or may with the consent, of the
Majority Lenders by notice to the Borrower demand, immediate delivery of cash
collateral, and the Borrower agrees to deliver such cash collateral upon demand,
in an amount equal to the maximum amount that may be available to be drawn at
any time prior to the stated expiry of all outstanding Letters of Credit,
provided that such cash collateral shall be immediately due and payable upon the
occurrence of any Event of Default described in Section 12.1.11. Such cash
collateral shall be deposited in a special cash collateral account to be held by
the Administrative Agent as collateral security and as a pledge for the payment
and performance of the Borrower's obligations under this Agreement to the Agents
and the Lenders.


                                    ARTICLE 8

                             CHANGE IN CIRCUMSTANCES

8.1      Substitute Basis - Alternate Interest Rate

         If a Lender determines in good faith that:

         8.1.1 adequate and fair means do not exist for ascertaining the rate of
interest on a Libor Loan Portion for the ensuing Interest Period,

         8.1.2 the making or the continuing of a Libor Loan Portion has become
impracticable by an event materially or adversely affecting the London interbank
market, or

         8.1.3 deposits in USDollars are not available to such Lender in the
London interbank market in sufficient amounts in the ordinary course of business
for the ensuing Interest Period in respect of a Libor Loan Portion, then, such
Lender may notify the Administrative Agent thereof and if such Lender so
notifies the Administrative Agent, the Administrative Agent shall promptly
notify the Borrower and the other Lenders in writing and, effective upon the
date such interest rate would otherwise become applicable, such Libor Loan
Portion shall be deemed for all purposes to be a US Base Rate Advance and the
interest rate applicable thereto shall be the applicable US Base Rate.

8.2      Increased Costs

         If, with respect to any Borrowing or accommodation of any kind or
nature provided by the Lenders under this Agreement (each such form of
accommodation being in this Section 8.2 referred to as a "Facility") and as a
result of or due to any change occurring after the date of this Agreement in any
Law, or in the interpretation or application thereof by any Governmental
Authority charged with the administration thereof or by reason of any compliance
with any guideline, request or requirement from any fiscal, monetary or other
authority (whether or not having the force of law),

         (a) a Lender incurs a cost (which it would not otherwise have incurred)
         or becomes liable to make a payment (calculated with reference to the
         amount outstanding under a Facility) with respect to continuing to
         provide or maintain a Facility or as a result of obligations of a
         Lender being outstanding hereunder in favor of third parties (other
         than a tax imposed on the overall income or net profits of such Lender
         or franchise taxes imposed in lieu thereof);

         (b) any reserve, special deposit or similar requirement is imposed or
         increased with respect to a Facility increasing the cost thereof to a
         Lender;

         (c) a Lender suffers or will suffer a reduction in the rate of return
         on its overall capital (other than a reduction by reason of any
         increase in the taxes referred to in (a) above) as a result of the
         amount of the capital that a Lender is required to maintain being
         increased or of any change in the manner in which a Lender is required
         to allocate its resources, or as a result of a requirement to attribute
         or allocate capital in respect of any undrawn portion of a Facility;

         (d) if there is any increase in the direct cost to a Lender of making 
         available the Facility; or

         (e) a Lender becomes liable to make any payment (not being the payment
         of tax on its overall income or net profits or franchise taxes imposed
         in lieu thereof) on or calculated by reference to the amount of a
         Facility;

then and in each such case the Borrower shall, subject to the terms and
conditions of this Section 8.2, pay to such Lender such amount (herein called
the "Compensating Amount") as will compensate such Lender for and will indemnify
such Lender against such increases in cost or reductions of rate of return or
liability with respect to the Facility.

         After the occurrence of an event having the effect set out in (a), (b),
(c), (d) or (e) above entitling a Lender to the payment of a Compensating Amount
and such Lender determining to claim such Compensating Amount, such Lender shall
forthwith give notice to the Borrower of the Compensating Amount claimed with
details of the events giving rise thereto and shall at that time or within
twenty (20) days thereafter provide to the Borrower a certificate setting out in
reasonable detail a compilation of the Compensating Amount claimed or, if such
Lender is then unable to determine the Compensating Amount or the method of
compilation thereof an estimate of such Compensating Amount and/or the method or
the basis on which such Lender estimates the calculation will be made which
estimate will be confirmed or adjusted by the aforesaid certificate. The
certificate of a Lender with respect to the Compensating Amount shall be final
and conclusive in the absence of manifest error.

         The Borrower shall within thirty (30) days of receipt of such notice
from a Lender pay to such Lender the Compensating Amount (or the estimated
Compensating Amount) claimed but, if the Compensating Amount claimed and paid is
greater or lesser than the Compensating Amount as finally determined, such
Lender or the Borrower, as the case may be, shall pay to the other the amount
required to adjust the payment to the Compensating Amount required to be paid.
The obligation to pay such a Compensating Amount for subsequent periods will
continue, subject as herein provided, until the earlier of the termination of
the Facility affected by the event referred to in the notice given by such
Lender to the Borrower or the lapse or cessation of the event giving rise to the
Compensating Amount.

         A copy of any notice or certificate given pursuant to this Section 8.2
shall be given to the Administrative Agent at the same time as such notice or
certificate is given.

8.3      Illegality

         Notwithstanding anything to the contrary contained in this Agreement,
if any introduction of or change occurring after the date of this Agreement in
any Law, policy, exchange control, guideline or official directive (whether or
not having the force of law) or any change in the interpretation or application
thereof by any court or by any Governmental Authority charged with the
administration thereof makes it unlawful or prohibited for a Lender to make,
fund or maintain all or any Libor Loan Portion or the Canadian Base Rate Loan,
or to give effect to its obligations contemplated by this Agreement, such Lender
shall notify the Borrower and the Administrative Agent in writing of the change
and, within the period specified by such Lender in the notice, at the option of
the Borrower:

         8.3.1 if such introduction or change so affects the Libor Loan Portion,
the Borrower shall elect (i) that interest on the Libor Loan Portion shall be
payable at the US Base Rate, or (ii) to repay and, within the time required by
the new law (or at the end of any longer period that such Lender at its
discretion may agree), the Borrower shall repay the Libor Loan Portion, together
with accrued interest up to the date of payment and all other amounts which are
due, and in any such event the obligation of the Lenders to make any further
Libor Advance or to allow any conversion of an Advance into a Libor Advance
shall terminate for so long as any circumstance entitling any Lender to give
such a notice shall continue.

8.4      Indemnity

         If the Borrower converts or prepays any amounts pursuant to Section 8.3
in respect to a Libor Loan Portion on a day other than the last day of an
Interest Period in respect of such Libor Loan Portion, the Borrower shall on
demand pay to the Administrative Agent, the amount required to indemnify the
Lenders for any loss, cost or expense incurred as a result of such conversion or
prepayment including, without limitation, any costs incurred in liquidating or
maintaining or redeploying deposits or other funds obtained by the Lenders to
fund such Libor Loan Portion. A certificate of the Lenders setting out the basis
of the determination of the amount necessary to indemnify them shall, in the
absence of manifest error, be conclusive and binding for all purposes.

8.5      Replacement of a Lender

         In the event a Lender has given a notice to the Borrower pursuant to
Section 8.1, 8.2 or 8.3, the Borrower shall (subject to the terms hereof) be
entitled to require (with a copy to the Administrative Agent) the Lender having
given such notice to assign to an alternate lender in accordance with Section
16.1.7 all of such Lender's rights and obligations hereunder and such alternate
lender shall execute all such documents as may be reasonably required by the
Administrative Agent, the Borrower and such Lender to effect such assignment,
provided that (i) each such assignment shall be arranged by the Borrower (with
such reasonable assistance from such Lender as the Borrower may request) after
consultation with the Administrative Agent and shall be an assignment of all of
the rights and obligations of the assigning Lender under this Agreement, (ii) no
Lender shall be obligated to make any such assignment as a result of a demand by
the Borrower pursuant to this Section 8.5 unless and until such Lender shall
have received payment from either the Borrower or the assignee in an aggregate
amount at least equal to the aggregate outstanding principal amount of the Loan
and Bid Loan and any Money Market Loans owing to such Lender, together with
accrued interest thereon to the date of payment of such principal amount and all
other amounts payable to such Lender under this Agreement (including, without
limitation, payment of any amounts owing to such Lender pursuant to Section 8.1,
8.2 or 8.3, as applicable, prior to the effective date of such assignment),
(iii) such alternate lender shall have been approved in writing by the
Administrative Agent, such approval not to be unreasonably withheld, and (iv)
any such assignment shall be subject to the restrictions set forth in Section
16.1.3.

         The Borrower shall make all payments hereunder regardless of any

9.7      Taxes

         (a) Any and all payments by the Borrower to or for the account of any
Lender or the Administrative Agent shall be made free and clear of and without
deduction for any and all present or future Taxes, duties, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Lender and the Administrative Agent, Taxes on the
overall income or net profits (or franchise taxes imposed in lieu thereof) of
such Lender or Administrative Agent imposed by the United States or any
political subdivision thereof or by any foreign jurisdiction in which such
Lender or Administrative Agent is organized or has its applicable lending office
(all such non-excluded Taxes, duties, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "Section 9.7
Taxes"). If the Borrower shall be required by law to deduct any Section 9.7
Taxes from or in respect of any sum payable hereunder to any Lender or the
Administrative Agent, (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this Section 9.7) such Lender or the
Administrative Agent (as the case may be) receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions, (iii) the Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
law and (iv) the Borrower shall furnish to the Administrative Agent the original
or a certified copy of a receipt evidencing payment thereof.

         (b) The Borrower agrees to indemnify each Lender and the Administrative
Agent for the full amount of Section 9.7 Taxes (including, without limitation,
any Section 9.7 Taxes imposed or asserted by any jurisdiction on amounts payable
under this Section 9.7) paid by such Lender or the Administrative Agent (as the
case may be) and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto. This indemnification shall be made
within 5 Business Days from the date such Lender or the Administrative Agent (as
the case may be) makes demand therefor.

         (c) Each Lender that is not a citizen or resident of the United States
of America, a corporation, partnership or other entity created or organized in
or under the laws of the United States of America or any state or political
subdivision thereof (a "Non-US Lender") shall deliver to the Borrower and the
Administrative Agent two copies of either US Internal Revenue Service Form 1001
or Form 4224, or, in the case of a Non-US Lender claiming exemption from US
federal withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of "portfolio interest", a Form W-8, or any subsequent versions
thereof or successors thereto (and, if such Non-US Lender does not deliver a
Form W-8, a certificate that such Lender is not a "bank" for purposes of Section
881(c) of the Code, is not a 10-percent shareholder (within the meaning of
Section 871(h)(3)(B) of the Code) of the Borrower and is not a controlled
foreign corporation related to the Borrower (within the meaning of section
864(d)(4) of the Code)), properly completed and duly executed by such Non-US
Lender claiming complete exemption from, US federal withholding tax on all
payments by the Borrower under this Agreement. Such forms shall be delivered by
each Non-US Lender on or before the date it becomes a party to this Agreement
and on or before the date, if any, such Non-US Lender changes its Applicable
Lending Office by designating a different lending office (a "New Lending
Office"). In addition, each Non-US Lender shall deliver such forms promptly upon
the obsolescence or invalidity of any form previously delivered by such Non-US
Lender. Each Non-US lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the US taxing authorities for such purpose) or if such certificate or
form becomes incorrect or invalid. The Borrower shall not be required to
indemnify any Non-US Lender, or to pay any additional amounts to any Non-US
Lender, in respect of United States federal withholding tax pursuant to Section
9.7(a) or (b) to the extent that the obligation to withhold amounts with respect
to the United States federal withholding tax existed on the date such Non-US
Lender became a party to this Agreement or, with respect to payments to a New
Lending Office, the date such Non-US Lender designated such New Lending Office
with respect to a Loan.

         (d) For any period with respect to which a Lender has failed to provide
the Borrower with the appropriate form pursuant to Section 9.7(c) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which a form originally was required to be provided), such Lender
shall not be entitled to increased amounts or indemnification under Section
9.7(a) or (b) with respect to Section 9.7 Taxes imposed by the United States;
provided, however, that should a Lender, which is otherwise exempt from
withholding tax, become subject to Section 9.7 Taxes because of its failure to
deliver a form required hereunder, the Borrower shall take such steps as such
Lender shall reasonably request (at such Lender's expense) to assist such Lender
to recover such Section 9.7 Taxes.

         (e) If the Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this Section 9.7, then such Lender will change
the jurisdiction of its Applicable Lending Office so as to eliminate or reduce
any such additional payment which may thereafter accrue if such change, in the
judgment of such Lender, is not otherwise disadvantageous to such Lender.

         (f) If any Lender or the Administrative Agent, as applicable, receives
a refund of or credit for a Tax for which a payment has been made by the
Borrower pursuant to this Section 9.7 which refund or credit in the good faith
judgment of such Lender or the Administrative Agent, as the case may be, is
attributable to such payment made by the Borrower, then the Lender or the
Administrative Agent, as the case may be, shall reimburse the Borrower for such
amount as the Lender or the Administrative Agent, as the case may be, determines
to be the proportion of the refund or credit as will leave it, after such
reimbursement, in no better or worse position than it would have been if the
payment had not been required. Each Lender and the Administrative Agent, as the
case may be, shall claim any refund or credit that it determines is available to
it, unless it concludes in its reasonable discretion that it would be adversely
affected by making such a claim.

         (g) Each Lender that is a partnership created or organized in or under
the laws of the United States of America or any state or political subdivision
thereof (a "U.S. Partnership Lender") shall deliver to the Borrower and the
Administrative Agent two copies of US Internal Revenue Service From W-9,
properly completed and duly executed by such US Partnership Lender, claiming
complete exemption from backup withholding. Such forms shall be delivered by
each U.S. Partnership Lender on or before the date it becomes a party to this
Agreement and promptly upon the obsolescence or invalidity of such forms. Each
U.S. Partnership Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower or any other form of certificate adopted
by the US taxing authorities for such purpose) or if such certificate or form
becomes incorrect or invalid.

9.8      Application of Payments

         All payments made by or on behalf of the Borrower to the Administrative
Agent for the account of the Lenders pursuant to this Agreement shall in each
instance be applied by the Administrative Agent in the following order:

         9.8.1 to amounts due hereunder other than those amounts described in
Sections 9.8.2, 9.8.3 and 9.8.4 hereof;

         9.8.2    to amounts due pursuant to Article 5 and Section 7.9.1;

         9.8.3    to repayment of amounts due in respect of the Loan; and

         9.8.4    to repayment of amounts due in respect of Bid Loans and Money 
Market Loans;

provided that after acceleration pursuant to Section 12.2, payments shall be
applied as the Lenders, in their discretion, may from time to time determine,
provided that payments on the Loan, the Bid Loans and the Money Market Loans
shall be made on a pro rata basis after acceleration.

9.9      Expenses and Indemnity

         9.9.1 The Borrower shall supply all statements, reports, certificates,
opinions, appraisals and other documents or information required to be furnished
to the Lenders or the Administrative Agent pursuant to this Agreement without
cost to any Lender or to the Administrative Agent.

         9.9.2 The Borrower shall reimburse and indemnify the Administrative
Agent (for itself and on behalf of the Lenders) and the other Agents, on demand,
all of the legal fees and disbursements (and tax on goods and services in
respect thereof) of Arrangers' Counsel and costs and other out-of-pocket
expenses (and tax on goods and services in respect thereof) reasonably incurred
from time to time in connection with (i) the due diligence, negotiation,
preparation and execution of this Agreement and any other documents referred to
herein or contemplated hereby, (ii) the negotiation, preparation and execution
of all waivers, amendments and variations in relation to this Agreement and any
other documents referred to herein or contemplated hereby, (iii) the operation
and interpretation of this Agreement and any agreement among the Lenders and the
Administrative Agent concerning their respective rights, remedies, duties and
responsibilities, and (iv) the syndication or arrangement of the Credit and
publicity, advertising and signing in connection with the Credit. In addition,
the Borrower agrees to pay on demand all of the legal fees of the Administrative
Agent and each of the Lenders and disbursements and costs and expenses (and tax
on goods and services in respect thereof) reasonably incurred in connection with
the enforcement of, or the preservation of any rights under, this Agreement and
the preservation, enforcement and realization of any other documents referred to
herein or contemplated hereby.

In addition, the Borrower shall pay or indemnify the Administrative Agent and
the Lenders against any and all stamp, registration and similar taxes which may
be payable in connection with the entry into, the performance of and the
enforcement of this Agreement.

         9.9.3 Without prejudice to the rights of the Lenders under the
provisions of Section 5.4, the Borrower agrees to indemnify each Lender against
any loss or expense which it may sustain or incur in obtaining or redeploying
deposits as a result of the failure by the Borrower to pay when due any
principal of the Loan or a Bid Loan or a Money Market Loan or for any reason to
borrow in accordance with a Notice of Borrowing or a Notice of Bid Borrowing or
other similar notice given by the Borrower to the Administrative Agent, to the
extent that any such loss or expense is not recovered pursuant to any other
provisions hereof. A certificate of a Lender or the Administrative Agent setting
forth the basis for the determination of the interest due on overdue principal
or interest and of the amounts necessary to indemnify such Lender in respect of
such loss or expense, submitted to the Borrower, shall be conclusive and binding
for all purposes except in case of manifest error.

         9.9.4 Notwithstanding any other provision of this Agreement, if for any
reason, including the acceleration of the maturity of the Loan, the Borrower
prepays, repays or converts all or any portion of the Libor Loan on a day other
than the last day of the then current Interest Period applicable to the Libor
Loan or a Libor Loan Portion, or if the Borrower, having given a Notice of
Borrowing requesting a Libor Advance, fails for any reason to fulfill on or
before the Drawdown Date for such Borrowing the applicable conditions set forth
in Article 10, the Borrower shall on demand pay to each Lender the amount
required to indemnify such Lender for any loss, cost or expense incurred by such
Lender as a result of such payment or conversion or failure to fulfil such
conditions including, without limitation, any loss or expense incurred in
liquidating or in maintaining or redeploying deposits or other funds obtained by
such Lender to fund or maintain the Libor Loan or such Libor Loan Portion. A
certificate of a Lender setting out the basis of the determination of the amount
necessary to indemnify it shall, in the absence of manifest error, be conclusive
and binding for all purposes.

         9.9.5 The Borrower agrees to indemnify and hold the Administrative
Agent and each of the Lenders harmless from and against any and all reasonable
claims, damages, losses, liabilities and expenses incurred, suffered or
sustained by the Administrative Agent or any of the Lenders by reason of,
relating to, arising out of or resulting from the Credit, the entering into,
carrying out or performance of this Agreement or any matter or document
contemplated herein by the Administrative Agent or a Lender, other than, in
respect of the Administrative Agent or a Lender, any such claim which arises as
a result of the gross negligence or wilful misconduct of the Administrative
Agent or such Lender.

9.10     Non-Receipt by Administrative Agent

         Where a sum is to be paid hereunder to the Administrative Agent for the
account of another party hereto, the Administrative Agent shall not be obliged
to make the same available to that other party hereto until it has been able to
establish that it has actually received such sum, but if it does pay out a sum
and it proves to be the case that it had not actually received the sum it paid
out, then the party hereto to whom such sum was so made available shall on
request ensure that the amount so made available is refunded to the
Administrative Agent, and shall on demand indemnify the Administrative Agent
against any cost or loss it may have suffered or incurred by reason of its
having paid out such sum prior to its having received such sum.

9.11     Indemnity by the Borrower

         The Borrower hereby indemnifies and holds the Lenders, the Agents and
their respective shareholders (provided such shareholders directly or indirectly
control any one of them), directors, partners (solely in the case of any Lender
or Agent that is a general or limited partnership), agents, officers,
Subsidiaries and affiliates (each an "Indemnified Party") harmless from and
against any and all damages, losses, settlement payments, obligations,
liabilities, claims, actions or causes of action, and costs and expenses
(collectively, "Indemnified Liabilities") incurred, suffered, sustained or
required to be paid by an Indemnified Party by reason of, relating to, arising

         Contaminant affecting, the property of the Borrower or any Subsidiary
         of the Borrower (the "Property") in violation of Environmental Laws,
         whether or not the same originates or emanates from any such Property
         or any contiguous real property, including any loss of value of any
         such Property as a result of any of the foregoing;

         (b) (i) any costs of removal or remedial action incurred by any
         federal, provincial, state, municipal, local or other government, (ii)
         any costs incurred by any other Person or damages from injury to,
         destruction of, or loss of natural resources, including costs of
         assessing such injury, destruction or loss incurred in relation with
         the Property, or (iii) the operators and activities of the Company or

         at, near, or with respect to the Property;

         (d) any investigative, administrative or judicial proceeding commenced

         shall be designated as a party or a potential party thereto, and any
         fees or expenses incurred by the Indemnified Parties in enforcing this
         indemnity, and all Indemnified Liabilities, whether based on any
         federal, state or foreign laws, statutes, rules or regulations
         (including securities and commercial laws, statutes, rules or
         regulations), on common law or equitable cause or on contract or
         otherwise, that may be imposed on, incurred by, or asserted against any
         such Indemnified Party, in any manner relating to or arising out of
         this Agreement, the Intercreditor Agreement or the Related Agreements
         or the transactions contemplated hereby or thereby (including the
         Lenders' agreement to make the Loan hereunder or the use or intended
         use of the proceeds thereof or the issuance of Letters of Credit
         hereunder or the use or intended use of any thereof), or any

other than, in respect to an Indemnified Party, any such claims which shall

Indemnified Party shall be entitled to select its own counsel, which shall be
subject to approval by the Borrower, acting reasonably, and, in addition to such
indemnity, the Borrower shall pay promptly the reasonable fees an expenses of
such counsel. Each Indemnified Party shall keep the Borrower advised on a
regular basis in regard to any such litigation or the preparation therefor and

representations to the Indemnified Party in respect thereof. This
indemnification obligation shall survive the execution hereof and the
termination of the Commitment of any Lender to make Advances hereunder.

9.12     Survival of Indemnification Obligations

         Without prejudice to the survival or termination of any other agreement
of the Borrower under this Agreement, the obligations of the Borrower under

in, or in connection with, this Agreement is incorrect or misleading in any
material respect; or

individually or in the aggregate at any time exceeds C$50,000,000 and such
failure shall continue after the applicable grace period, if any, specified in

failure diligently and in good faith and in respect of which no final
non-appealable judgment or order for the payment of money has been rendered and
no execution proceedings have been commenced and are unstayed; or any other
default which has not been cured or waived under any agreement or instrument
relating to any such Indebtedness, the amount of which individually or in the
aggregate at any time exceeds C$50,000,000, of the Company or any of its
Subsidiaries, or any other event, shall occur and shall continue after the

instalment or other payment (within the meaning of Section 412(n) of the Code or
Section 302(f) of ERISA) shall have occurred with respect to any Plan or Plans

encumbrance in favor of a Plan or the PBGC; or (ii) a trustee shall be appointed

liability which in the aggregate may exceed C$50,000,000; or

consummated, shall be unwound, reversed or otherwise rescinded in whole or in
part for any reason, or (iii) prior to the Merger Date, any party to the Merger
Agreement shall have taken action to terminate the Merger Agreement; provided,
however, that the occurrence of any of the events described in this Section
12.1.10 shall not constitute an Event of Default if on or prior to the first
anniversary of the Initial Funding Date (x) all outstanding Term Loans and
Canadian Term Loans shall have been repaid and (y) the Revolving Loan
Commitments and the commitments to make Canadian Revolving Loans under the
Canadian Credit Agreement (and all outstanding Revolving Loans and Canadian

basis (according to the initial amounts thereof) to an aggregate amount not
exceeding US$500,000,000 or the Equivalent Amount in CDollars; or

         12.1.11 the Company or any Material Subsidiary shall not pay its debts
generally as such debts become due, or shall admit in writing its inability to
pay its debts generally as they become due, or shall make a general assignment
for the benefit of creditors; or any proceeding shall be commenced or instituted
by or against the Company, or any Material Subsidiary seeking to adjudicate it
bankrupt or insolvent, or seeking winding-up, reorganization, arrangement,
adjustment, dissolution, protection, relief, liquidation or composition of it or
its debt under any law relating to bankruptcy, insolvency or reorganization or
relief of debtors, or seeking appointment of a receiver, trustee, sequestrator
or other similar official for it or for any substantial or material part of its
property or seeking the suspension of the operations of the Company or any
Material Subsidiary and, in the case of any such proceeding instituted against
the Company or any Material Subsidiary and in respect of which the Company or
any Material Subsidiary has not by any act indicated its consent to, approval
of, or acquiescence in, such proceeding, such proceeding shall remain
undismissed for a period of sixty (60) days; or the Company, or any Material
Subsidiary shall take corporate action to authorize any of the actions set forth
above in this Section 12.1.11 or

         12.1.12 at any time prior to the later of the STB Approval Date and the
Merger Date, the Target shall fail to perform, observe or comply with any of the
covenants contained in Section 6 of the Merger Agreement and such failure could
reasonably be expected to result in a Material Adverse Effect; provided,
however, that such failure shall not constitute an Event of Default (i) if such
failure would not, if Target were a Subsidiary of the Borrower for all
purposes hereunder, constitute an Event of Default under any other Section of
this Article 12, and (ii) unless such failure shall remain unremedied for a
period of thirty (30) days.

12.2     Effect of a Default

         Upon the occurrence and during the continuation of any Event of
Default, the Administrative Agent shall at the request, or may with the consent,
of the Majority Lenders, by notice to the Company (i) declare the obligation of
the Lenders to make Advances or Bid Advances to the Borrower to be terminated,
whereupon the same shall forthwith terminate, and/or (ii) declare the Loan and
the Bid Loan, all interest accrued and unpaid thereon and all other amounts
payable under this Agreement to be forthwith due and payable, whereupon the Loan
and the Bid Loan, all such accrued interest and all such other amounts shall
become and be forthwith due and payable, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the
Borrower and each of the Guarantors. Thereupon the Borrower shall immediately
pay to the Administrative Agent all such amounts due and payable. In addition to
the foregoing, in the event of the institution of any proceeding against the
Borrower or a Material Subsidiary or the Borrower or any Material Subsidiary
making an assignment for the general benefit of creditors or otherwise
voluntarily initiating any proceeding in respect of its property or creditors
under any Law relating to bankruptcy, insolvency or organization or relief of
debtors the effect of which is to cause an automatic stay to come into effect
with respect to the Borrower or a Material Subsidiary or an actual or deemed
entry of an order for relief with respect to any proceeding instituted by or
against the Borrower or a Material Subsidiary under the U.S. Federal Bankruptcy
Code, the Bankruptcy and Insolvency Act (Canada) or the Companies' Creditors
Arrangement Act (Canada) (as amended, supplemented or replaced from time to
time), as may be applicable, or any other applicable bankruptcy or insolvency
laws which provide for an automatic stay, the obligation of each Lender to make
Advances or Bid Advances shall automatically be terminated and the Loan and the
Bid Loan, all interest accrued and unpaid thereon and all other amounts payable
under this Agreement shall automatically become due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower and each of the Guarantors. For greater
certainty, the Borrower and each of the Guarantors will be considered to be in
default of their obligations hereunder by the mere lapse of time provided herein
for performing such obligations, without any requirement of further notice or
other act of the Administrative Agent or the Lenders unless a notice is
specifically required hereunder.

12.3     Remedies Cumulative; No Waiver

         For greater certainty, it is expressly understood and agreed that the
rights and remedies of the Lenders and the Administrative Agent under this
Agreement are cumulative and are in addition to, not in substitution for, any
rights or remedies provided by law; no failure on the part of the Lenders or the
Administrative Agent to exercise, and no delay in exercising, any right or
remedy hereunder or thereunder shall operate as a waiver thereof, nor shall any
single or partial exercise by the Lenders or the Administrative Agent of any
right or remedy for a default or breach of any term, covenant, condition or
agreement herein contained prejudice or preclude any other or further exercise
thereof or the exercise of any other right or remedy for the same or any other
default or breach and shall not waive, alter, affect or prejudice any other
right or remedy.

12.4     Set-Off

         In addition to, and not in limitation of, any rights now or hereafter
granted under applicable Law, each Lender is hereby expressly authorized (but
not obliged), at any time or from time to time upon the occurrence and during
the continuation of an Event of Default, to set off or compensate and to
appropriate and to apply any and all deposits, general or special, matured or
unmatured, and any other Indebtedness at any time held by or owing by such
Lender to, or for the credit of, or the account of, the Borrower or any of the
Guarantors against and on account of the obligations and liabilities of the
Borrower or each of the Guarantors due and payable to such Lender under this
Agreement including, without limitation, all claims of any nature or description
arising out of, or connected with, this Agreement, irrespective of whether or
not any demand therefor has been made and although such obligations and
liabilities of, or claims against, the Borrower or any of the Guarantors, are
contingent or unmatured. Each Lender shall upon any such set-off, compensation
or appropriation give immediate notice to the Administrative Agent and the other
Lenders and thereafter give notice to the Borrower.

Business Day; provided however that notices and communications to the
Administrative Agent pursuant to Article 3, Article 4, Section 5.5 and Section
7.7 hereof shall not be effective until actually received by the Administrative
Agent. In the event of a postal strike or any slow-down in the postal service,
no notice of or communication by mail shall be effective if sent during or
within five (5) Business Days prior to the commencement of, such strike or
slow-down unless it is actually received by the party to whom it is addressed
and, in such event, it shall be effective only on the date of actual receipt.

          THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,

                  ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY LOAN PARTY
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OBLIGATIONS THEREUNDER, MAY

COUNTY AND CITY OF NEW YORK. BY EXECUTING AND DELIVERING THIS AGREEMENT, EACH
LOAN PARTY, FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, IRREVOCABLY

                  (I) ACCEPTS GENERALLY AND UNCONDITIONALLY THE NONEX- CLUSIVE
         JURISDICTION AND VENUE OF SUCH COURTS;

                  (II) WAIVES ANY DEFENSE OF FORUM NON CONVENIENS;

                  (III) AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH
         PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED
         MAIL, RETURN RECEIPT REQUESTED, TO SUCH LOAN PARTY AT ITS ADDRESS
         PROVIDED IN ACCORDANCE WITH SECTION 13.1;

                  (IV) AGREES THAT SERVICE AS PROVIDED IN CLAUSE (III) ABOVE IS
         SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER SUCH LOAN PARTY IN ANY
         SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE
         AND BINDING SERVICE IN EVERY RESPECT;

                  (V) AGREES THAT LENDERS RETAIN THE RIGHT TO SERVE PROCESS IN

         LOAN PARTY IN THE COURTS OF ANY OTHER JURISDICTION; AND

                  (VI) AGREES THAT THE PROVISIONS OF THIS SECTION 14.2 RELATING

To the extent that any Loan Party now or hereafter may be entitled, in any
jurisdiction in which proceedings may at any time be commenced with respect to
this Agreement, to claim for itself or its revenues, assets or properties any
sovereign immunity (including, without limitation, immunity from service of
process, jurisdiction, suit, judgment, counterclaim, enforcement of or execution
on a judgment, attachment prior to the judgment, attachment in aid of execution
of a judgment or other legal process), and to the extent that in any
jurisdiction there may be attributed any such sovereign immunity (whether or not
claimed), each Loan Party hereby irrevocably undertakes not to claim and hereby
irrevocably waives any such immunity to the fullest extent permitted by law.

14.3     Judgment Currency

         14.3.1 If for any purpose, including the obtaining of judgment in any
court, it is necessary to convert a sum due hereunder from the currency in which
it is payable (the "Payment Currency") into another currency (the "Judgment
Currency"), the parties hereto agree, to the fullest extent that they may
lawfully and effectively do so, that the rate of exchange used shall be that at
which, in accordance with normal banking procedures, the Administrative Agent
could purchase the Payment Currency with the Judgment Currency in the New York
foreign exchange market on the Business Day preceding the date of final
judgment.

         14.3.2 The obligation of the Borrower in respect of any sum due from it
to the Lenders or the Administrative Agent hereunder shall, notwithstanding any
judgment or payment in a currency other than the Payment Currency, be discharged
only to the extent that on the Business Day following receipt by the
Administrative Agent of any sum so paid or adjudged to be so due in the Judgment
Currency the Administrative Agent may in accordance with normal banking
procedures, purchase the Payment Currency with the amount of the Judgment
Currency so paid or adjudged to be due; if the amount in the Payment Currency so
purchased is less than the sum originally due to the Lenders and the
Administrative Agent in the Payment Currency, the Borrower and each Guarantor
agrees, as a separate obligation and additional cause of action and
notwithstanding any such payment or judgment, to indemnify the Lenders and the
Administrative Agent against such loss and if the amount in the Payment Currency
so purchased exceeds the sum originally due to the Lenders and the
Administrative Agent in the Payment Currency, the Lenders and the Administrative
Agent agree to remit to the Borrower such excess.

         14.3.3 The term "rate of exchange" in this Section 14.3 means the spot
rate at which the Administrative Agent, in accordance with normal practices, is
able on the relevant date to purchase the Payment Currency with the Judgment
Currency and includes any premium and costs of exchange payable in connection
with the purchase.

                           THE AGENTS AND THE LENDERS

15.1     Authorization of Agents

         Each Lender hereby irrevocably appoints and authorizes each of the
Arrangers, the Advisor, the Syndication Agent, the Co-Documentation Agents and
the Administrative Agent to act as its agent hereunder with such powers as are
expressly delegated to the such Agent by the terms of this Agreement and the
Intercreditor Agreement, together with such other powers as are reasonably
incidental thereto; each Lender hereby authorizes and confirms the appointment
by Administrative Agent of Bank of Montreal as Repayment Agent under the
Intercreditor Agreement; and each Lender and Administrative Agent hereby
authorizes Repayment Agent to act as its agent in accordance with the terms of
the Intercreditor Agreement. Each Agent shall have no duties or responsibilities
except those expressly set forth in this Agreement or, in the case of the
Administrative Agent and the Repayment Agent, in the Intercreditor Agreement. As
to any matters not expressly provided for by this Agreement, the Administrative
Agent shall act hereunder or in connection herewith in accordance with
instructions of the Majority Lenders but, in the absence of any such
instructions, the Administrative Agent may (but shall not be obliged to) take
such action as it deems it necessary to protect the rights of the Lenders, and
any such instructions and any action taken by the Administrative Agent in
accordance herewith shall be binding upon all the Lenders. Each Agent shall not,
by reason of this Agreement, or, in the case of the Repayment Agent, by reason
of the Intercreditor Agreement, be deemed to be a trustee for the benefit of any
Lender, the Borrower, the Guarantors or any other Person. None of the Agents nor
any of their respective directors, officers, employees or agents shall be
responsible to the Lenders for any recitals, statements, representations or
warranties contained in this Agreement or in any certificate or other document
referred to, or provided for in, or received by any of them under, this
Agreement, for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement, or any other document referred to, or provided
for, herein or any collateral provided for hereby or for any failure by the
Borrower or any of the Guarantors to perform its obligations hereunder. The
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. None of the Agents nor any of their respective
directors, officers, employees or agents shall be responsible for any action
taken or omitted to be taken by it or them under or in connection herewith,
except for its or their own gross negligence or wilful misconduct. As of the
date on which Syndication Agent notifies the Borrower that it has concluded its
primary syndication of the Loan and Commitments, all obligations of the
Arrangers, the Advisor and the Syndication Agent, in such capacities hereunder,
shall terminate.

15.2     Agents' Responsibility

         15.2.1 Each Agent shall be entitled to rely upon any certificate,
notice or other document (including any cable or telegram) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper person or persons, and upon advice and statements of legal advisers,
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat each Lender as the holder of the
Participation in the Loan made by such Lender and as the holder of its share of
any Bid Loans and as the holder of Money Market Loans made by it for all
purposes hereof unless and until an assignment or transfer has been accepted by
the Borrower and the Guarantors and the Administrative Agent in accordance with
Article 16.

         15.2.2 The Administrative Agent shall not be deemed to have knowledge
of the occurrence of an Event of Default unless the Administrative Agent has
received notice from a Lender or the Borrower or a Guarantor describing such an
Event of Default and stating that such notice is a "Notice of Default". In the
event that the Administrative Agent receives such a notice of the occurrence of
an Event of Default, the Administrative Agent shall promptly give notice thereof
to the Lenders. The Administrative Agent shall take such action with respect to
such Event of Default as shall be directed by the Majority Lenders, provided
that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obliged to) take such
action, or refrain from taking such action, with respect to such an Event of
Default as it shall deem advisable in the best interest of the Lenders.

         15.2.3 The Agents shall have no responsibility (i) to the Borrower or
any of the Guarantors on account of the failure of any Lender to perform its
obligations hereunder, or (iii) to any Lender on account of the failure of the
Borrower or any of the Guarantors to perform its obligations hereunder.

         15.2.4 Each of the Lenders severally represents and warrants to the
Agents that it has made its own independent investigation of the financial
condition and affairs of each of the Borrower and each of the Guarantors in
connection with the making and continuation of its Participation in the Loan or
its Bid Advances or Money Market Loans hereunder and has not relied on any
information provided to such Lender by any Agent in connection herewith, and
each Lender represents and warrants to the Agents that it shall continue to make
its own independent appraisal of the creditworthiness of the Borrower and each
of the Guarantors while the Loan or any Bid Loan or any Money Market Loan is
outstanding or any Commitment is in force.

15.3     Rights of Agents as Lenders

         With respect to its Commitments and its Participation in the Loan and
any Bid Loans made by it, each Agent in its capacity as a Lender shall have the
same rights and powers hereunder as any other Lender and may exercise the same
as though it were not acting as an Agent and the terms "Lender" or "Lenders"
shall, unless the context otherwise indicates, include such Agent in its
capacity as a Lender. Each Agent may (without having to account therefor to any
Lender) accept deposits from, lend money to and generally engage in any kind of
banking, or other business with the Borrower or any of the Guarantors as if it
were not acting as an Agent.

15.4     Indemnity

         The Lenders agree to indemnify each Agent (to the extent not otherwise
reimbursed by the Borrower or the Guarantors) rateably in accordance with their
respective Participation in the Loan (or, if no Advances have been made,
rateably in accordance with their respective Commitments), for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
cost, expenses or disbursements of any kind and nature whatsoever which may
be imposed on, incurred by, or asserted against, such Agent in any way relating
to or arising out of this Agreement or any other documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
(excluding, unless an Event of Default is apprehended or has occurred and is
continuing, normal administrative costs and expenses incidental to the
performance of its agency duties hereunder) or the enforcement of any of the
terms hereof or of any such other documents, provided that no Lender shall be
liable for any of the foregoing to the extent they arise from such Agent's gross
negligence or wilful misconduct.

15.5     Notice by Administrative Agent to Lenders

         Promptly after its receipt thereof, the Administrative Agent will
forward to each Lender a copy of each report, notice or other document required
by this Agreement to be delivered to the Administrative Agent for such Lender.

15.6     Protection of Agents

         15.6.1 No Agent shall be required to keep itself informed as to the
performance or observance by the Borrower or any of the Guarantors of this
Agreement or any other document referred to or provided for herein or to inspect
the properties or books of the Borrower or any of the Guarantors. Except for
notices, reports and other documents and information expressly required to be
furnished to the Lenders by an Agent hereunder, or, in the case of the Repayment
Agent, in accordance with the Intercreditor Agreement, such Agent shall have no
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs or financial condition of the Borrower or any
of the Guarantors which may come into the possession of such Agent. Nothing in
this Agreement, or, in the case of the Repayment Agent, in the Intercreditor
Agreement, shall oblige any Agent to disclose any information relating to the
Borrower or any of the Guarantors if such disclosure would or might in the
opinion of such Agent constitute a breach of any law or duty of secrecy or
confidence.

         15.6.2 Unless the Administrative Agent shall have been notified in
writing or by tested cable by any Lender prior to the date of an Advance or Bid
Advance requested hereunder that such Lender does not intend to make available
to the Administrative Agent such Lender's Participation in such Advance or Bid
Advance, the Administrative Agent may assume that such Lender has made such
Lender's Participation in such Advance or Bid Advance available to the
Administrative Agent on the date of such Advance or Bid Advance and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such corresponding amount is not in fact
made available to the Administrative Agent by such Lender, the Administrative
Agent shall be entitled to recover such amount (together with interest thereon
at the rate determined by the Administrative Agent as being its cost of funds in
the circumstances) on demand from such Lender or, if such Lender fails to
reimburse the Administrative Agent for such amount on demand, from the Borrower.

         15.6.3 Unless the Administrative Agent shall have been notified in
writing or by cable by the Borrower prior to the date on which any payment is
due hereunder that the Borrower does not intend to make such payment, the
Administrative Agent may assume that the Borrower has made such payment when so
due and the Administrative Agent may, in reliance upon such assumption, make
available to each Lender on such payment date an amount equal to such Lender's
pro rata share of such assumed payment. If it proves to be the case that the
Borrower has not in fact made such payment to the Administrative Agent, each
Lender shall forthwith on demand repay to the Administrative Agent the amount
made available to such Lender (together with interest at the rate determined by
the Administrative Agent as being its cost of funds in the circumstances).

15.7     Notice by Lenders to Administrative Agent

         Each Lender shall endeavor to use its best efforts to notify the
Administrative Agent of the occurrence of any event which by the giving of
notice or lapse of time or both would constitute an Event of Default forthwith
upon becoming aware of such event and of any legal proceeding such Lender
intends to take against the Borrower or any of the Guarantors in virtue of this
Agreement, but no Lender shall be liable if it fails to give such notice to the
Administrative Agent.

15.8     Resignation of Administrative Agent

         Subject to the appointment and acceptance of a successor Administrative
Agent (as provided below) (i) the Administrative Agent may resign at any time by
giving not less than thirty (30) days written notice thereof to the Lenders and
the Borrower, and (ii) the Administrative Agent may be removed at any time with
cause by the Majority Lenders by giving not less than thirty (30) days written
notice of their intention to do so to the Administrative Agent and the Borrower.
Upon such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent, which, if no Event of Default has
occurred and is continuing, must be acceptable to the Borrower. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation or receiving of notice of
removal, then the retiring Administrative Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent which, if no Event of Default has
occurred and is continuing, must be acceptable to the Borrower.

         If (i) the Total Commitment has been cancelled or terminated, (ii) the
Loan has been repaid, and (iii) the Administrative Agent has no outstanding Bid
Loans, the Administrative Agent may resign at any time by giving not less than
thirty (30) days' written notice thereof to the Lenders with outstanding Bid
Loans and the Borrower. If no agreement is reached by the parties to whom such
notice is given within such thirty (30) day period on the appointment of a
successor Administrative Agent, the Administrative Agent may appoint as a
successor Administrative Agent the Lender with the highest amount of outstanding
Bid Loans and such Lender shall become the Administrative Agent effective on
such appointment.

         Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, or upon the appointment by the
Administrative Agent of a successor Administrative Agent as aforesaid, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent, the provisions of this 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 the Administrative Agent.

15.9     Sharing Among the Lenders

         The Lenders agree among themselves that, except as otherwise provided
for by the provisions of this Agreement, all sums received by the Administrative
Agent in its capacity as agent of the Lenders, for the ratable account of the
Lenders relative to this Agreement or any other document contemplated hereby
(whether received by voluntary payment, by the exercise of the right of set-off
or compensation or by counterclaim, cross action or as proceeds of realization
of any security) shall be shared by each Lender pro rata, in accordance with
their respective Participations and each Lender undertakes to do all such things
as may be reasonably required to give full effect to this Section 15.9. If any
sum which is so shared is later recovered from the Lender who originally
received it, each of the other Lenders shall restore its proportionate share of
such sum to such Lender, without interest.

         If any Lender obtains any payment (whether voluntary, involuntary or
through the exercise of any right of set-off or compensation or by counterclaim,
cross-action or as proceeds of realization of any security) on account of the
Loan in excess of its ratable share of payments on account of the Loan obtained
by all the Lenders, such Lender shall promptly deliver such amount to the
Administrative Agent for distribution to all Lenders pro rata in accordance with
their respective Participations.

         Each Lender agrees with the other Lenders that it will not, without the
prior written consent of the other Lenders, take or obtain any Lien on any
property of the Company or any Material Subsidiary to secure the obligations of
the Borrower or any of the Guarantors hereunder, except for the benefit of all
Lenders or as may otherwise be required by Law.

15.10    Intercreditor Agreement

         Each Lender hereby further authorizes Administrative Agent and the
Repayment Agent, on behalf of and for the benefit of Lenders, to enter into the
Intercreditor Agreement, and each Lender agrees to be bound by the terms of the
Intercreditor Agreement.

15.11    Provisions for the Benefit of Lenders Only

         The provisions of this Article 15 relating to the rights and
obligations of the Lenders and Administrative Agent inter se shall be operative
as between the Lenders and Agents only, and the Borrower and the Guarantors
shall not have any rights or obligations under or be entitled to rely for any
purposes upon such provisions except for Sections 15.8 and 15.14.

15.12    Amendment of Article 15

         Except for such provisions of Section 15.8 and Section 15.14 that
relate to the Borrower, the provisions of this Article 15 may be amended or
added to, from time to time, by execution by the Administrative Agent and the
Lenders of an instrument in writing and such instrument in writing shall validly
and effectively amend or add to any or all of the provisions of this Article 15
affecting the Lenders without requiring the execution of such instrument in
writing by the Borrower or any of the Guarantors. Notwithstanding the foregoing
sentence, for so long as no Event of Default has occurred and is continuing, the
second and third sentences of Section 15.13 cannot be amended without the
consent of the Borrower.

15.13    Authorized Waivers, Variations and Omissions

         If so authorized in writing by Majority Lenders, the Administrative
Agent may grant waivers, consents, vary the terms of this Agreement, and do or
omit to do all such acts and things in connection herewith or therewith. Except
with the prior written agreement of all the Lenders, nothing in this Section
15.13 shall authorize (i) any increase in the Total Commitment or subject the
Lenders to any additional financial or other material obligations, (ii) any
extension of the Term Loan Maturity Date, (iii) any extension of the Revolving
Loan Commitment Termination Date, (iv) any change in the definition of Majority
Lenders, (v) any reduction in any of the interest rates or fees (other than
agency fees payable to the Administrative Agent) provided for in this Agreement,
(vi) postpone any date fixed for any payment of interest or fees or (vii) any
amendments to any guarantees, security, if any, or Section 15.9 or this Section
15.13. Save as otherwise provided in Article 15 and in Section 16.1.2, all
instructions, decisions, approvals, consents or actions referred to in this
Agreement and required of the Lenders shall be made, taken or given by the
Majority Lenders. No amendment, waiver or consent shall, unless in writing and
signed by the applicable Agent in addition to the Lenders required herein to
take such action, affect the rights or duties of such Agent under this
Agreement. Notwithstanding anything in this Agreement to the contrary, (a) in
the event Majority Lenders or all Lenders shall consent to any amendment,
modification or waiver of any provision contained in Articles 2, 10, 11 or 12
(other than Sections 12.1.1, 12.1.2 and 12.1.11) of this Agreement, or the
definitions in Article 1 as used in such Articles, including without limitation
any waiver of compliance therewith as a condition to making any Advance or Bid
Advance, such amendment, modification or waiver shall not be effective
(notwithstanding approval thereof by Majority Lenders or all Lenders) with
respect to either this Agreement or the Canadian Credit Agreement unless such
amendment, modification or waiver is effective with respect to both such
agreements and any fees which are paid by the Company or any of its Subsidiaries
to obtain consent to any such amendment, modification or waiver are paid on a
ratable basis to Lenders and "Lenders" (as defined in the Canadian Credit
Agreement) who consent to such amendment, modification or waiver, and the
Lenders hereunder hereby consent to any such amendment, modification or waiver
in this Agreement and the Canadian Credit Agreement as is necessary to give
effect to this sentence, and (b) any change in the definition of Majority
Lenders or to this Section 15.13 shall require the prior written agreement of
all Lenders and all "Lenders" as defined in the Canadian Credit Agreement.

15.14    Dissenting Lenders

         If a Lender (in this Section 15.14 called a "Dissenting Lender")
withholds its consent or its approval following a request of the Borrower as
provided in this Agreement and, as a result, the consent of all the Lenders or
the Majority Lenders, as the case may be, cannot be obtained in connection with
such request, the Borrower may, provided at least 51% of the Lenders based on
the amount of the Total Commitment in effect from time to time have consented to
such request, by giving notice to each Dissenting Lender and to the Agent within
ten (10) days of being advised by the Administrative Agent of whether the
Lenders or the Majority Lenders, as the case may be, have consented to such
request, designate an alternate lender (which need not be an existing Lender) to
purchase an assignment in accordance with Section 16.1.7 of such Dissenting
Lender's Commitments and outstanding Loan and Bid Loan and Money Market Loans
(which alternative lender shall purchase such assignment prior to the expiry of
such ten (10) day delay) provided that no Lender shall be obligated to make any
such assignment as a result of a demand by the Borrower pursuant to this Section
15.14 unless said assignment is done on a without warranty basis and unless and
until such Dissenting Lender shall have received one or more payments from
either the Borrower or one or more assignees in an aggregate amount at least
equal to the aggregate outstanding principal amount of the Loan and Bid Loan and
Money Market Loans owing to such Dissenting Lender, together with accrued
interest thereon to the date of payment of such principal amount and all other
amounts payable to such Dissenting Lender under this Agreement. Any such
alternate lender is subject to the Administrative Agent's prior written
approval, such approval not to be unreasonably withheld. Nothing contained
herein shall be deemed to obligate any Lender or the Administrative Agent to
agree to any such request made by the Borrower.


                                   ARTICLE 16

                             SUCCESSORS AND ASSIGNS

16.1     Successors and Assigns

         16.1.1 This Agreement shall become effective when it shall have been
executed by the Borrower, the Guarantors, the Administrative Agent, the
Arrangers, the Advisor, the Syndication Agent and each Lender and thereafter
shall be binding upon and enure to the benefit of the Borrower, the Guarantors,
the Administrative Agent, the Arrangers, the Advisor, the Syndication Agent, the
Lenders and their respective successors and permitted assigns.

         16.1.2 Neither the Borrower nor any of the Guarantors shall have the
right to assign their rights or obligations hereunder or any interest herein
without the prior written consent of all the Lenders, which consent may be
arbitrarily withheld.

         16.1.3 A Lender may (i) without notice to or consent of any Person,
grant participations in its interest in the Credit to one or more Persons (each
a "Participant"); or (ii) with the consent of the Borrower (but not the
Guarantors) which consent shall not be unreasonably withheld or delayed, assign
its rights and obligations in the Credit to one or more financial institutions
(each an "Assignee") in whole or in part, subject to the following limitations:

                           (w) any such Assignee shall be subject to approval by
         the Administrative Agent and no such consent of the Borrower or
         approval of the Administrative Agent shall be required for assignments
         by a Lender to an Affiliate of such Lender or to another Lender or
         during the occurrence and continuance of an Event of Default;

                           (x) no Lender shall assign its Commitments (except to
         Affiliates of such Lender and to other Lenders) in amounts less than
         US$10,000,000 (or such lesser amount as shall constitute the aggregate
         amount of the Commitments and Advances of such Lender) in the
         aggregate;

                           (y) no Lender may assign its Revolving Loan
         Commitment or Term Loan Commitment or Advances except together with a
         proportionate share of all Commitments and Advances held by such
         Lender; and

                           (z) notwithstanding anything to the contrary
         contained herein, no Lender may assign its Advances or Commitments
         except to a citizen or resident of the United States of America, a
         corporation, partnership or other entity created or organized in or
         under the laws of the United States of America or any state or
         political subdivision thereof or any other Person that is completely
         exempt from U.S. federal withholding provisions with respect to all
         payments to be made by the Borrower hereunder.

Except in the case of an Assignee which has delivered an assumption agreement
pursuant to Section 16.1.7, the Participant or Assignee shall not have any
rights under this Agreement (such Person's rights against such Lender in respect
of such participations and assignments to be those set forth in the agreement
executed by such Lender in favor of such Person relating thereto and such Person
shall not constitute a "Lender" hereunder). With respect to all such
participations (i) the obligations under this Agreement of each Lender selling a
participation interest hereunder shall remain unmodified and fully effective and
enforceable against such Lender, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the party entitled to receive payments for all
purposes of this Agreement, (iv) the Borrower, the Administrative Agent and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, and
(v) such Lender shall not grant to its Participant(s) any rights to consent or
withhold consent to any action taken by such Lender or the Administrative Agent
under this Agreement other than action requiring the consent of all of the
Lenders hereunder.

         In addition to the assignments and participations permitted under the
foregoing provisions of this Section 16.1, any Lender may assign and pledge all
or any portion of its rights and obligations in the Credit, and any other
Obligations owed to such Lender to any Federal Reserve Bank as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System and any operating circular issued by such Federal Reserve Bank;
provided that (i) no lender shall, as between the Borrower and such Lender, be
relieved of any of its obligations hereunder as a result of any such assignment
and pledge and (ii)in no event shall such Federal Reserve bank be considered to
be a "Lender" or be entitled to require the assigning Lender to take or omit any
action hereunder.

         16.1.4 Subject to Section 16.1.9, the Lenders may deliver a copy of any
financial statement or any other information relating to the business, assets or
condition (financial and otherwise) of the Company and its Subsidiaries or the
Guarantors which may be furnished to them under this Agreement or otherwise to
any prospective or other Participant or Assignee to the extent reasonably
required by such Participant or Assignee in connection with its interest or the
proposed acquisition of an interest in the Credit or a Bid Loan or any Money
Market Loans.

         16.1.5 The Borrower and each of the Guarantors shall provide such
certificates, acknowledgements and further assurances in respect of this
Agreement and the Credit or a Bid Loan or a Money Market Loan as such Lender may
reasonably require in connection with any participation or assignment pursuant
to Section 16.1.3.

         16.1.6 Except in the case of an Assignee which has delivered an
assumption agreement pursuant to Section 16.1.7:

         (a) a Lender granting a participation or making an assignment shall
         remain a "Lender" hereunder and shall act on behalf of all of its
         Participants and Assignees in all dealings with the Borrower and the
         Guarantors in respect of the Credit and the Bid Loans and any Money
         Market Loans;

         (b) the Participant or Assignee shall not constitute a "Lender" 
         hereunder; and

         (c) all amounts payable by the Borrower hereunder shall be determined
         as if such Lender had not granted such participation or made such
         assignment.

         16.1.7 A Lender may deliver to the Borrower, the Guarantors and the
Administrative Agent an agreement substantially in the form of Schedule 16.1.7
annexed hereto by which any Assignee of such Lender assumes the obligations and
agrees to be bound by all the terms and conditions of this Agreement, all as if
such Assignee had been an original party hereto. Upon any such assignment and
assumption of the obligations of such Lender by an Assignee:

         (a) the Administrative Agent shall, upon receipt of a fee of US$2,500
         from the Assignee (provided that such fee shall be paid by the Borrower
         in the event of any assignment pursuant to Section 7.12 or 8.5), record
         the assignment and any modified Commitments resulting therefrom; and

         (b) the assigning Lender, the Borrower and the Guarantors shall be
         released from their respective obligations hereunder (to the extent of
         such assignment and assumption) and thereafter shall not have any
         liability or obligations to each other to such extent, except in
         respect of matters arising prior to such assignment.

In the event a Lender assigns the full amount of its Loan and Commitments and
such Lender has an outstanding Bid Loan and/or any Money Market Loans at the
time of such assignment, such Lender must also assign the full amount of such
Bid Rate Loans and Money Market Loans to a Person which is a Lender at the time
of such assignment.

         16.1.8 The Borrower and each of the Guarantors hereby consents to the
disclosure by each Lender to any Participant or Assignee of all information in
regard to this Agreement. The Borrower and each of the Guarantors further agrees
to co-operate fully with each Lender in connection with any transaction pursuant
to Section 16.1.7 and to execute and deliver such documents and assurances as a
Lender may reasonably request in connection therewith including, without
limitation, the agreement referred to in Section 16.1.7.

         16.1.9 Each Lender and the Administrative Agent agrees (on behalf of
itself and each of its Affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with their customary procedures for handling confidential information
of this nature and in accordance with safe and sound lending practices, any
non-public information supplied to it by the Company or any of its Subsidiaries
pursuant to this Agreement (and which is not independently known to such Lender
or the Administrative Agent) provided that nothing herein shall limit the
disclosure of any such information (i) to the extent required by Law or judicial
process, (ii) to counsel for any of the Lender or the Administrative Agent,
(iii) to a Lender's examiners, auditors or accountants, (iv) to the
Administrative Agent or any other Lender, (v) in connection with any litigation
to which any one or more of the Lenders is a party, (vi) to any Affiliate of any
Lender or the Administrative Agent, or (vii) to any Assignee or Participant (or
prospective Assignee or Participant) so long as such Assignee or Participant (or
prospective Assignee or Participant) first executes and delivers to the
respective Lender a Confidentiality Agreement substantially in the form of
Schedule 16.1.9 annexed hereto; provided, further, that, unless specifically
prohibited by applicable Law or court order, each Lender shall, prior to
disclosure thereof, notify the Company of any request for disclosure of any such
non-public information (x) by any governmental agency or representative thereof
(other than any such request in connection with an examination of such Lenders
financial condition by such governmental agency), or (y) pursuant to legal
process; and provided finally that in no event shall any Lender or the
Administrative Agent be obligated or required to return any materials furnished
by the Company or any of its Subsidiaries.

         16.1.10 No Lender shall be entitled to grant a participation or an
assignment pursuant to Section 16.1.3 or to change its branch of account, as the
case may be, if, as a result, the Borrower would be required to pay or reimburse
the Participant or Assignee for any Taxes under Section 9.7 or any Compensating
Amount under Section 8.2.

         16.1.11 Each Lender listed on the signature pages hereof hereby
represents and warrants (i) that it has experience and expertise in the making
of loans such as the Term Loans and/or the Revolving Loans, as applicable; and
(ii) that it will make its Advances for its own account in the ordinary course
of its business and without a view to distribution of its interest in the Credit
within the meaning of the Securities Act or the Exchange Act or other federal
securities laws (it being understood that, subject to the provisions of this
Article 16, the disposition of such interests in the Credit shall at all times
remain within its exclusive control). Each Lender listed on the signature pages
hereof hereby represents and warrants that it is a citizen or resident of the
United States of America, a corporation, partnership or other entity created or
organized in or under the laws of the United States of America or any state or
political subdivision thereof or any other Person that is completely exempt from
U.S. federal withholding tax with respect to all payments to be made by the
Borrower hereunder. Each Lender that becomes a party hereto after the date
hereof shall be deemed to represent and warrant that it is a citizen or resident
of the United States of America, a corporation, partnership or other entity
created or organized in or under the laws of the United States of America or any
state or political subdivision thereof or any other Person that is exempt from
U.S. federal withholding tax with respect to all payments to be made by the
Borrower hereunder.


                                   ARTICLE 17

                                    GUARANTEE

         17.1     Guarantee

         Each of the Guarantors, for good and valuable consideration received,
hereby absolutely, irrevocably and unconditionally guarantees, as primary
obligor and not merely as surety, in favor of each of the Lenders and the
Administrative Agent, the prompt and complete payment when due, whether at
stated maturity, by acceleration or otherwise, of all present and future
obligations of the Borrower resulting from the terms and conditions of this
Agreement, including without limitation, the repayment of the Bid Loan and the
Loan and all reimbursement obligations under any Letters of Credit, together
with interest thereon and all fees and other amounts as provided in this
Agreement (such obligations being herein called the "Obligations"). Each of the
Guarantors shall be considered as primarily liable to the Lenders and the
Administrative Agent, and shall not be released nor its liability hereunder
limited or lessened by any variation or departure from the provisions of this
Agreement nor by the Lenders or the Administrative Agent's granting time, taking
or giving up securities, accepting compositions, granting releases or
discharges, or otherwise dealing with any Person, nor by any other thing
whatsoever, either of a like nature to the foregoing or otherwise whereby as
guarantor only, a Guarantor would or might be released, and none of the Lenders
or the Administrative Agent shall be bound to exhaust its recourse against the
Borrower or any other Person or any security it may hold before being entitled
to payment from each of the Guarantors. The Guarantors covenant and agree that
until such time as each of the Lenders and the Administrative Agent shall have
been indefeasibly paid in full all Obligations, no payment will be taken,
demanded, received or accepted by a Guarantor of or on account of the principal
amount of or interest of any indebtedness incurred by a Guarantor in fulfillment
of its obligations pursuant to this Section 17.1 or on any other indebtedness
payable by the Borrower, each of the Guarantors agreeing that this said
indebtedness shall, at all times, be fully subordinated to and rank in time and
right of payment junior to the Obligations, and each of the Guarantors hereby
renounces any rights of compensation and/or set-off and/or counterclaim. Without
limiting the foregoing, each of the Guarantors hereby expressly subordinates and
postpones all of its rights to the benefit of subrogation (whether contractual,
under the Bankruptcy Code, under common law or otherwise) and all contractual,
common law, statutory and other rights of reimbursement, contribution,
exoneration or indemnity (or any similar right) from or against the Borrower
which may have arisen in connection with this guarantee, and agrees not to
enforce or attempt to enforce any of the foregoing, until indefeasible full
repayment of the Obligations and the termination of all Letters of Credit and
the Total Commitment. Each of the Guarantors hereby determines and agrees that
the execution, delivery and performance of this Agreement by such Guarantor is
necessary and convenient to the conduct, promotion or attainment of the business
of the Borrower and the Guarantors and in furtherance of the corporate purposes
of the Guarantors. Notwithstanding anything herein to the contrary, the
obligations of CNR Properties arising under this Article 17 are solely with
respect to the obligations of Canadian National Railway Company under this
Agreement in its capacity as a Guarantor and arise only to the extent it is
permitted to guarantee such obligations under applicable Law. Upon the
reasonable request of the Administrative Agent, CNR Properties will execute a
guarantee agreement with substantially the same effect as this Article 17 in
order to guarantee the obligations of any future Guarantor under this Agreement
to the extent that CNR Properties is permitted to guarantee such obligations
under applicable law.

17.2     Guarantee Absolute

         Each of the Guarantors guarantees that the Obligations will be paid
strictly in accordance with the terms of this Agreement, regardless of any Law,
regulation, or order now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Administrative Agent or the Lenders with
respect thereto. The liability of each of the Guarantors under this Agreement
shall be absolute and unconditional irrespective of:

         (i) any lack of validity or enforceability of any provisions of this
         Agreement, or any other agreement or instrument relating to this
         Agreement;

         (ii) any change in the time, manner or place of payment of or in any
         other term of, all or any of the Obligations or any other amendment,
         restatement or waiver of or any consent to departure from this
         Agreement;

         (iii) any exchange, release or non-perfection of any collateral or any
         release or amendment or waiver of or consent to departure from any
         other guarantee, for all or any of the Obligations;

         (iv) the reconstruction, reorganization, consolidation, amalgamation or
         merger of the Borrower with or into any other Person, or the transfer,
         sale, lease or other disposition by the Borrower of all or
         substantially all of its assets or business to any other Person,
         whether or not affected in compliance with the provisions of this
         Agreement;

         (v) the illegality under any applicable Law of repayment of the
         Obligations or the adoption of any Law purporting to render any
         Obligations null and void;

         (vi) any defense, setoff or counterclaim which may at any time be
         available to or asserted by any Guarantor against the Administrative
         Agent or any Lender; or

         (vii) any other circumstance which might otherwise constitute a defense
         available to, or a discharge of, the Borrower or a guarantor.

         The liability of each of the Guarantors under this Article 17 shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment of any of the Obligations is rescinded or must otherwise be returned
by the Administrative Agent or any Lender upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, all as though such payment had not
been made.

17.3     Waiver

         Each of the Guarantors hereby waives promptness, diligence, notice of
acceptance, presentment, protest, demand, notice of default, and any other
notice with respect to any of the Obligations and its liability hereunder and
any requirement that the Administrative Agent or any Lender protect, secure,
perfect or insure any Lien, if any, or any property subject thereto or exhaust
any right or take any action against the Borrower or any other Person or any
collateral.

17.4     Continuing Guarantee

         The obligations of each of the Guarantors under this Article 17 shall
be a continuing guarantee and shall:

         (i) remain in full force and effect until payment in full of the
         Obligations and all other amounts payable under this Agreement;

         (ii) be binding upon each of the Guarantors, its successors and
         assigns; and

         (iii) enure to the benefit of and be enforceable by the Lenders, the
         Administrative Agent and their respective successors, transferees and
         assigns.

         Without limiting the generality of the foregoing clause (iii), upon any
assignment by any Lender of all or any part of any interest in this Agreement by
it to any other Person in accordance with the terms of this Agreement, such
other Person shall thereupon become vested with all the rights in respect
thereof granted to such Lender herein or otherwise, subject, however, to the
provisions of this Agreement concerning the Administrative Agent and subject to
compliance with Section 16.1.7.

17.5     Fraudulent Conveyance Limitation

         17.5.1 Anything contained in this Article 17 to the contrary
notwithstanding, if any Fraudulent Transfer Law (as hereinafter defined) is
determined by a court of competent jurisdiction to be applicable to the
obligations of any Guarantor (other than the Company ) under this Article 17,
such obligations of such Guarantor hereunder shall be limited to a maximum
aggregate amount equal to the largest amount that would not render its
obligations hereunder subject to avoidance as a fraudulent transfer or
conveyance under Section 548 of Title 11 of the United States Code or any
applicable provisions of comparable state law (collectively, the "Fraudulent
Transfer Laws"), in each case after giving effect to all other liabilities of
such Guarantor, contingent or otherwise, that are relevant under the Fraudulent
Transfer Laws (specifically excluding, however, any liabilities of such
Guarantor (x) in respect of intercompany indebtedness to the Borrower or other
affiliates of the Borrower to the extent that such indebtedness would be
discharged in an amount equal to the amount paid by such Guarantor hereunder and
(y) under any guaranty of subordinated indebtedness which guaranty contains a
limitation as to maximum amount similar to that set forth in this Section
17.5.1, pursuant to which the liability of such Guarantor hereunder is included
in the liabilities taken into account in determining such maximum amount) and
after giving effect as assets to the value (as determined under the applicable
provisions of the Fraudulent Transfer Laws) of any rights to subrogation,
reimbursement, indemnification or contribution of such Guarantor pursuant to
applicable law or pursuant to the terms of any agreement (including without
limitation any such right of contribution under Section 17.5.2).

         17.5.2 Guarantors together desire to allocate among themselves, in a
fair and equitable manner, their obligations arising under this Article 17.
Accordingly, in the event any payment or distribution is made on any date by any
Guarantor under this Article 17 (a "Funding Guarantor") that exceeds its Fair
Share (as defined below) as of such date, that Funding Guarantor shall be
entitled to a contribution from each of the other Guarantors in the amount of
such other Guarantor's Fair Share Shortfall (as defined below) as of such date,
with the result that all such contributions will cause each Guarantor's
Aggregate Payments (as defined below) to equal its Fair Share as of such date.
"Fair Share" means, with respect to a Guarantor as of any date of determination,
an amount equal to (i) the ratio of (x) the Adjusted Maximum Amount (as defined
below) with respect to such Guarantor to (y) the aggregate of the Adjusted
Maximum Amounts with respect to all Guarantors, multiplied by (ii) the aggregate
amount paid or distributed on or before such date by all Funding Guarantors
under this Article 17 in respect of the obligations guarantied. "Fair Share
Shortfall" means, with respect to a Guarantor as of any date of determination,
the excess, if any, of the Fair Share of such Guarantor over the Aggregate
Payments of such Guarantor. "Adjusted Maximum Amount" means, with respect to a
Guarantor as of any date of determination, the maximum aggregate amount of the
obligations of such Guarantor under this Article 17, determined as of such date
in accordance with Section 17.5.1; provided that, solely for purposes of
calculating the "Adjusted Maximum Amount" with respect to any Guarantor for
purposes of this Section 17.5.2, any assets or liabilities of such Guarantor
arising by virtue of any rights to subrogation, reimbursement or indemnification
or any rights to or obligations of contribution hereunder shall not be
considered as assets or liabilities of such Guarantor. "Aggregate Payments"
means, with respect to a Guarantor as of any date of determination, an amount
equal to (i) the aggregate amount of all payments and distributions made on or
before such date by such Guarantor in respect of this Guaranty (including,
without limitation, in respect of this Section 17.5.2) minus (ii) the aggregate
amount of all payments received on or before such date by such Guarantor from
the other Guarantors as contributions under this Section 17.5.2. The amounts
payable as contributions hereunder shall be determined as of the date on which
the related payment or distribution is made by the applicable Funding Guarantor.
The allocation among Guarantors of their obligations as set forth in this
Section 17.5.2 shall not be construed in any way to limit the liability of any
Guarantor hereunder.

17.6     Taxes

         17.6.1 Any and all payments to the Lenders by the Guarantors in respect
of the Obligations, shall be made free and clear of and without deduction or
withholding for any and all present or future Taxes excluding, in the case of
each Lender and the Administrative Agent, (i) Taxes on the overall income or net
profits (or franchise taxes imposed in lieu thereof) of such Lender or
Administrative Agent imposed by any jurisdiction in which such Lender or
Administrative Agent is organized or has its Applicable Lending Office, and (ii)
in the case of each Lender and the Administrative Agent, Taxes imposed solely by
reason of the Lender or the Administrative Agent (as the case may be) doing
business in the jurisdiction imposing such Tax, other than as a result of this
Agreement or any transaction contemplated hereby (all Taxes, other than such
excluded Taxes, being hereinafter referred to as "Section 17.6 Taxes") unless
such Taxes are required by law or the administration thereof to be deducted or
withheld. If any Guarantor shall be required by Law or the administration
thereof to deduct or withhold any such Section 17.6 Taxes from or in respect of
any such amount payable hereunder then, (i) the amount payable shall be
increased as may be necessary so that after making all required deductions or
withholdings (including deductions or withholdings applicable to additional
amounts paid under this Section 17.6), the Lenders receive an amount equal to
the amount they would have received if no such deduction or withholding had been
made; (ii) such Guarantor shall make such deductions or withholdings; and (iii)
such Guarantor forthwith shall pay the full amount deducted or withheld to the
relevant taxation or other authority in accordance with applicable Law.

         17.6.2 Each Guarantor agrees to pay forthwith any present or future
stamp documentary taxes or any other excise or property taxes, charges or
similar levies (all such taxes, charges and levies being herein referred to as
"Other Taxes") imposed by any jurisdiction (or any political subdivision or
taxing authority thereof or therein) which arise from any payment made by the
Guarantors hereunder.

         17.6.3 Each Guarantor agrees to indemnify the Lenders for the full
amount of (i) Section 17.6 Taxes and Other Taxes, not deducted or withheld and
paid by such Guarantors in accordance with Section 17.6.1 and 17.6.2 to the
relevant taxation or other authority and (ii) any Section 17.6 Taxes or Other
Taxes imposed by any jurisdiction on amounts payable by any Guarantor under this
Section 17.6, in each case paid by the Lenders and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not any such Taxes or Other Taxes were correctly or legally asserted;
provided that, if such Taxes or Other Taxes were incorrectly or illegally
imposed, such Lender shall, at the reasonable request of the applicable
Guarantor, take all reasonable actions that are without risk or material cost to
such Lender to claim and obtain refunds with respect to such Taxes or Other
Taxes and will promptly remit such refunds after receipt thereof to such
Guarantor. Payment under this indemnification shall be made within 15 days from
the date the Administrative Agent or the relevant Lenders make written demand
therefor. A certificate as to the amount of such Taxes or Other Taxes, providing
reasonable details of the calculation thereof, and evidence of payment thereof
submitted to the relevant Guarantor by the Administrative Agent shall be prima
facie evidence of the amount due from such Guarantor to the Administrative Agent
or the Lenders.

         17.6.4 Each Guarantor shall furnish to the Administrative Agent and the
relevant Lenders the original or a certified copy of a receipt evidencing any
payment of Taxes or other Taxes made by such Guarantor, as soon as such receipt
becomes available.

                  Each Lender and the Administrative Agent agrees that it will
(i) take all reasonable actions reasonably requested by the Guarantor that are
without risk or material cost to such Lender or the Administrative Agent (as the
case may be) to maintain all exemptions, if any, available to it from
withholding taxes (whether available by treaty or existing administrative
waiver), and (ii) to the extent reasonable and without material cost to it,
otherwise cooperate with the Guarantor to minimize any amounts payable by the
Guarantor under this Section.

                  If the Guarantor is required to pay additional amounts to or
for the account of any Lender pursuant to this section 17.6, then such Lender
will change the jurisdiction of its Applicable Lending Office so as to eliminate
or reduce any such additional payment which may thereafter accrue if such
change, in the judgment of such Lender, would not impose material cost on such
Lender and is not otherwise disadvantageous to such Lender.

         17.6.5 The provisions of this Section 17.6 shall survive the
termination of the Agreement and the repayment of all Advances and Bid Advances
and all Money Market Loans.


                                   ARTICLE 18

                                  MISCELLANEOUS

18.1     Severability

         Any provision of this Agreement which is or becomes prohibited or
unenforceable in any jurisdiction shall not invalidate, affect or impair the
remaining provisions hereof and any such prohibition or unenforceability in any
jurisdiction does not invalidate or render unenforceable any such provision in
any other jurisdiction.

18.2     Amendments, Waivers. Etc.

         Except as specifically provided in Section 15.12, no amendment,
modification or waiver of any provision of, and no waiver of the strict
observance, performance or compliance by the Borrower or each of the Guarantors
with any term, covenant, condition or agreement contained in this Agreement and
no indulgence granted by the Administrative Agent or the Lenders or consent to
any departure by the Borrower or any of the Guarantors therefrom, shall in any
event be effective unless it shall be in writing and signed by, as the case may
be, the Majority Lenders or the Administrative Agent on behalf of the Lenders or
the Majority Lenders, as required, and the Borrower and each of the Guarantors,
and then such amendment, modification, waiver or consent shall be effective only
in the specific instance and for the specific purpose for which it is given.

18.3     Direct Obligation

         Notwithstanding any other provision hereof, the Borrower shall be
obligated directly towards each of the Lenders in respect of the Participation
of each of the Lenders as well as any other amounts which may be payable by the
Borrower pursuant to or in connection with this Agreement or any Borrowings. The
obligations of each of the Lenders are independent from one another, are not
joint, and may not be increased, reduced, extinguished or otherwise affected due
to the default of another Lender pursuant hereto. Any default of any party
hereto in the performance of its obligations shall not release any of the other
parties hereto from the performance of any of their respective obligations.

18.4     Sharing of Information

         The Borrower and each of the Guarantors agrees that the Administrative
Agent and the Lenders may share amongst themselves any information which any of
them may possess concerning the Borrower or any of the Guarantors in respect of
the Borrower's and each of the Guarantors' undertakings, obligations or
indebtedness towards any Lender pursuant to this Agreement or otherwise, as well
as any payment received from the Borrower or any of the Guarantors by any
Lender. Without limiting the generality of the foregoing, the Administrative
Agent may disclose to any Lender and the Borrower and any of the Guarantors any
information contained in any notices, consents, certificates, documents or other
instruments or writings delivered to it under or pursuant to this Agreement.

18.5     Term of Agreement

         This Agreement shall continue in full force and effect until both the
Total Commitment of the Lenders has terminated and all Obligations (other than
inchoate indemnification obligations with respect to claims, losses or
liabilities which have not yet arisen) of the Borrower and each of the
Guarantors under or pursuant to this Agreement have been indefeasibly paid and
satisfied in full.

18.6     Further Assurances

         The Borrower and each of the Guarantors agrees to do, execute,
acknowledge, deliver or cause to be done, executed, acknowledged or delivered
all such further acts, deeds, documents, opinions and assurances as may be
reasonably requested by the Administrative Agent or any Lender from time to time
during the term hereof for the purpose of effecting the transactions
contemplated hereby.

18.7     Execution in Counterparts

         This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed shall be deemed to be an original and all of which taken together shall
constitute but one and the same agreement.

18.8     [Intentionally Omitted]

18.9     Whole Agreement

         This Agreement and the letters referred to in Sections 5.7 and 5.9 in
regard to the underwriting fee and administrative fee constitute the whole
agreement between the parties in respect of the Credit and the Bid Loans, and as
and from the date of this Agreement cancel and supersede any other prior
agreements, undertakings, declarations and representations, written or oral, in
respect thereto.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective representatives thereunto duly authorized as of the
date first above written.
