3.    Press Release

      The press release of Canadian National Railway Company and Burlington
      Northern Santa Fe Corporation was issued at Montreal, Quebec and Fort
      Worth, Texas on December 20, 1999. A copy of the press release is
      annexed hereto.


4.    Summary of Material Change

      Canadian National Railway Company ("CN") and Burlington Northern Santa
      Fe Corporation ("BNSF") announced that their boards of directors have
      approved a definitive agreement to combine their businesses.


5.    Full Description of Material Change

      Canadian National Railway Company ("CN") and Burlington Northern Santa
      Fe Corporation ("BNSF") announced that their boards of directors have
      approved a definitive agreement to combine their businesses. The
      end-to-end combination will create North America's largest railroad and
      will offer shippers substantially enhanced single-line service.
      Combined, the companies currently operate about 50,000 route-miles of
      track, employ about 67,000 people and have combined revenues of
      approximately US$12.5 billion (Cdn$18.5 billion).

<PAGE>

                                      -2-


      The combined businesses have an equity market capitalization of
      approximately US$19 billion (Cdn$28 billion) based on the closing stock
      prices on Friday, December 17, 1999, of US$29.75 for CN and US$28.375
      for BNSF. The transaction is expected to be accretive to earnings per
      share in the first year after the combination becomes effective. The
      companies expect that all required regulatory approvals can be obtained
      and the transaction completed by mid-2001.

      Terms of the Combination

      To implement the transaction in a tax-efficient manner, North American
      Railways, Inc. ("NAR") will be created as the parent company for BNSF
      and as the companion company for CN. The transaction will result in the
      shareholders of each company having voting and ownership interests in
      both companies.

      The shareholders of BNSF will receive for each BNSF common share a
      common security consisting of one North American Railways common share
      and one CN voting share that will trade together as one security.

      The shareholders of CN will receive for each CN common share 1.05 CN
      voting shares and, at their option, either 1.05 shares of North American
      Railways common stock or 1.05 shares of CN stock exchangeable for 1.05
      shares of North American Railways common stock. The CN voting share will
      trade together with the CN exchangeable share as one security and will be
      Canadian Property for investment, dividend and tax purposes.

      The result will be that, at all times, each company will have the same
      shareholder base with each shareholder having the same economic benefits
      and voting rights.

      North American Railways, by its charter, will conform to the provisions of
      the CN Commercialization Act and Canadian corporate law on the composition
      of boards of directors. Like CN, North American Railways shareholders will
      be subject to an ownership limit whereby no single shareholder can own
      more than 15 percent of North American Railways' voting shares; North
      American Railways will have its head office in Montreal and will operate
      in both of Canada's official languages. BNSF will continue to be
      headquartered in Fort Worth.

      Boards of Directors and Management

      Upon the closing of the transaction, Robert D. Krebs, Chairman and Chief
      Executive Officer of BNSF, will become non-executive Chairman of North
      American Railways and of CN; and Paul M. Tellier, President and Chief
      Executive Officer of CN, will become President and Chief Executive Officer
      of North American Railways as well as CN. E. Hunter Harrison, Executive
      Vice President and Chief Operating Officer of CN, will become Chief
      Operating Officer of North American Railways as well as CN; and Thomas N.
      Hund, Senior Vice President, Chief Financial Officer and Treasurer of
      BNSF, will become Chief Financial

<PAGE>

                                      -3-


      Officer of North American Railways and of CN. In addition, Matthew K.
      Rose, President and Chief Operating Officer of BNSF, will become President
      and Chief Executive Officer of BNSF.

      A five-person implementation committee, consisting of Mr. Krebs, Mr.
      Tellier, Mr. Harrison, Mr. Hund and Mr. Rose, will begin work immediately.
      The mandate of this committee, which will operate through consensus, is to
      direct the preparation of the U.S. Surface Transportation Board (STB)
      application and related matters, to direct integration planning and,
      within regulatory limits, to effect interim voluntary coordination
      agreements between CN and BNSF in such areas as information systems,
      purchasing, operations and marketing.

      The size and composition of the North American Railways board will be
      identical to that of the CN board. The majority of directors will be
      Canadian residents. The 15-member board will consist of six members drawn
      from each of the current CN and BNSF boards plus three new appointees:

    o From the current CN board: Purdy Crawford, J. V. Raymond Cyr, The
      Honorable Edward C. Lumley, David G. A. McLean, Robert Pace, and Paul M.
      Tellier;

    o From the current BNSF board: John J. Burns, Jr., Robert D. Krebs, Roy S.
      Roberts, J. Steven Whisler, Edward E. Whitacre, Jr., and Michael B.
      Yanney;

    o The three new appointees: Laurent Beaudoin, C.C., FCA, Chairman,
      Bombardier Inc.; Steven A. Burd, Chairman, President & Chief Executive
      Officer, Safeway Inc.; Jean C. Monty, President & Chief Executive Officer,
      BCE Inc.

      Conditions

      This combination is subject to, among other things, approval by the
      shareholders of both companies, as well as to customary regulatory
      approvals. CN will proceed with a Plan of Arrangement (the "Arrangement")
      that will be submitted to a Canadian court to confirm that the combination
      is fair to CN shareholders and complies with all relevant Canadian
      statutory and regulatory requirements. The combination will also be
      subject to approval by the STB. The combination will be accounted for as a
      purchase.

      Non-Solicitation

      Each party has agreed that neither it nor any of its subsidiaries nor any
      of the officers and directors of it or its subsidiaries shall, and that it
      shall direct and use its best efforts to cause its and its subsidiaries'
      employees, agents and representatives (including any investment banker,
      attorney or accountant retained by it or any of its subsidiaries)
      (collectively, "its representatives") not to, directly or indirectly,
      initiate, solicit, encourage or otherwise facilitate any inquiries or the
      making of any proposal or offer with respect to an Alternative Proposal
      (as defined). Each of the parties has further agreed that neither it nor
      any of its subsidiaries nor any of the officers and directors of it or any
      of its subsidiaries

<PAGE>

                                      -4-


      shall, and that it shall direct and use its best efforts to cause its
      representatives not to, directly or indirectly, have any discussion with
      or provide any confidential information or data relating to or in
      contemplation of an Alternative Proposal or engage in any negotiations or
      discussions concerning an Alternative Proposal, or otherwise facilitate
      any effort or attempt to make or implement an Alternative Proposal;
      provided, however, that nothing contained in the Combination Agreement
      shall prevent either party or its directors from: (A) complying with Rule
      14d-9 and Rule 14e-2 promulgated under the U.S. Securities Exchange Act,
      1934 with regard to an Alternative Proposal or, in the case of CN,
      complying with the requirements of the CBCA and applicable Canadian
      securities laws in relation to the preparation and dissemination of
      directors' circulars in response to take-over bids and the calling and
      holding of requisitioned stockholders meetings; (B) prior to the taking of
      the vote to be taken at their respective stockholder meetings, engaging in
      any discussions or negotiations with, or providing any information to, any
      person in response to an unsolicited bona fide written Alternative
      Proposal; or (C) prior to the taking of the vote to be taken at their
      respective stockholder meetings, subject to the obligation to duly convene
      the stockholder meetings at which a vote of the stockholders shall be
      taken regarding the approval and adoption of the applicable merger or
      Arrangement resolutions, recommending such an unsolicited bona fide
      written Alternative Proposal to the stockholders of such party if, and
      only to the extent that, with respect to the actions referred to in
      clauses (B) or (C), (i) such party has complied with the terms of this
      covenant, (ii) the board of directors of such party concludes in good
      faith (after consultation with its outside legal counsel and its financial
      advisors) that such Alternative Proposal is reasonably capable of being
      completed, taking into account all legal, financial, regulatory and other
      aspects of the proposal and the person making the proposal, and would, if
      consummated, result in a transaction more favorable to such party's
      stockholders from a financial point of view than the transactions
      contemplated by the Combination Agreement, (iii) the board of directors of
      such party determines in good faith after consultation with outside legal
      counsel that the failure to take such action would result in the
      reasonable likelihood that the board of directors would breach its
      fiduciary duties to the company or its stockholders under applicable law,
      and (iv) prior to entering into negotiations or discussions with, or
      providing any information or data to, any person in connection with an
      Alternative Proposal by any such person, the board of directors of such
      party shall receive from such person an executed confidentiality agreement
      on terms substantially similar to those contained in the confidentiality
      agreement between CN and BNSF; provided, however, that such
      confidentiality agreement shall contain terms that allow such party to
      comply with its obligations under this covenant. For these purposes, the
      Combination Agreement provides that an "Alternative Proposal" means, with
      respect to any person, any proposal or offer with respect to a merger,
      organization, amalgamation, arrangement, share exchange, consolidation,
      business combination, recapitalization, liquidation, dissolution or
      similar transaction involving such person, or any purchase or sale of the
      consolidated assets (including stock of such person's subsidiaries) of
      such person or any of its subsidiaries, taken as a whole, having an
      aggregate value equal to 15% or more of its market capitalization, or any
      purchase or sale of, or

<PAGE>

                                      -5-


      tender or exchange offer for, 15% or more of such person's or any of such
      person's subsidiaries' equity securities.

      The parties have also agreed to immediately cease and cause to be
      terminated any existing activities, discussions or negotiations with any
      parties conducted heretofore with respect to any Alternative Proposal and
      to take the necessary steps to promptly inform each of its representatives
      of the obligations undertaken. Each party has agreed that it will notify
      the other party promptly, but in any event within twenty-four (24) hours,
      if any such inquiries, proposals or offers are received by, any such
      information is requested from, or any such discussions or negotiations are
      sought to be initiated or continued with, any of its representatives
      indicating, in connection with such notice, the name of such person making
      such inquiry, proposal, offer or request and the substance of any such
      inquiries, proposals or offers and the status of any such discussions or
      negotiations. Without limiting the generality of the foregoing, the notice
      (which the Combination Agreement requires to be given by a party at least
      five business days in advance of any public announcement or other
      dissemination of the withdrawal, modification or change in such party's
      board of directors' recommendation to its stockholders in respect of the
      transactions contemplated by the Combination Agreement) shall set forth
      all material terms of the Alternative Proposal or other matter forming the
      basis for the withdrawal, modification or change by such party's board of
      directors of its recommendation and such notice shall be updated in
      writing on a current basis in the event that any such materials terms are
      modified or changed. Without limiting the recipient's right to make
      proposals in general, the recipient of such notice shall be permitted to
      make one or more proposals to such party during this five business day
      period and such proposals shall be considered by such party. The parties
      have also agreed to promptly request each person that has heretofore
      executed a confidentiality agreement in connection with its consideration
      of any Alternative Proposal to return all confidential information
      heretofore furnished to such person by or on behalf of such party or any
      of its subsidiaries.

      Termination and Break Fee Events; Options

      The Combination Agreement may be terminated and the transactions
      contemplated by the Combination Agreement may be abandoned at any time
      prior to the closing (notwithstanding any approval by the shareholders of
      BNSF or CN):

      (i)   by mutual written consent of BNSF and CN;
      (ii)  by either BNSF or CN, if the closing has not occurred by December
            31, 2002 (the "Outside Date");
      (iii) by either BNSF or CN, if (a) any judgment, injunction, order or
            decree enjoining BNSF or CN from consummating the merger or
            Arrangement is entered and such judgment, injunction, order or
            decree shall become final and nonappealable or (b) the court elects
            not to issue the final order approving the Arrangement and the
            court's decision on the matter has

<PAGE>

                                      -6-

            been fully appealed (and not reversed) or has become final and
            nonappealable;
      (iv)  by either BNF or CN, if the approvals of the stockholders of BNSF or
            CN contemplated by the Combination Agreement shall not have been
            obtained by reason of the failure to obtain the required vote at a
            duly held meeting of stockholders or of any adjournment thereof;
      (v)   by BNSF, if the board of directors of CN shall have withdrawn,
            adversely modified or changed its approval or recommendation of the
            Combination Agreement, the transactions contemplated by the
            Combination Agreement or the Arrangement resolution;
      (vi)  by CN, if the board of directors of BNSF shall have withdrawn,
            adversely modified or changed its approval or recommendation of the
            Combination Agreement or the transactions contemplated by the
            Combination Agreement;
      (vii) by BNSF, upon a breach of any representation, warranty, covenant or
            agreement of CN, or if any representation or warranty of CN shall
            become untrue, in either case such that the conditions set forth in
            Section 8.2 of the Combination Agreement would be incapable of being
            satisfied by the Outside Date (or as otherwise extended), provided
            that a wilful breach shall be deemed to cause such conditions to be
            incapable of being satisfied by such date;
      (viii) by CN, upon a breach of any representation, warranty, covenant or
            agreement of BNSF or NAR, or if any representation or warranty of
            BNSF or NAR shall become untrue, in either case such that the
            conditions set forth in Section 8.3 of the Combination Agreement
            would be incapable of being satisfied by the Outside Date (or as
            otherwise extended), provided that a wilful breach shall be deemed
            to cause such conditions to be incapable of being satisfied by such
            date; or
      (ix)  by either BNSF or CN at any time prior to December 31, 2002, if the
            STB shall have issued a decision (which decision shall not have been
            stayed or enjoined) that (A) constitutes a final order approving,
            exempting or otherwise authorizing consummation of the transactions
            contemplated by the Combination Agreement (or subsequently presented
            to the STB by agreement of BNSF and CN), including the Arrangement
            and the merger, as may require such authorization and (B)(1) changes
            the exchange ratio or (2) imposes on BNSF, NAR, CN or any of their
            respective subsidiaries any other terms or conditions (including
            labor protective provisions, but excluding conditions heretofore
            imposed by the United States Interstate Commerce Commission in New
            York Dock Railway-Control-Brooklyn Eastern District, 360 I.C.C. 60
            (1979)) that would significantly and adversely affect the economic
            benefits of the transactions contemplated by the Combination
            Agreement to BNSF, CN and their stockholders, taken as a whole (such
            decision, an "Adverse STB Decision").

BNSF, after consulting with its counsel, deems it necessary to do so in the
exercise of its fiduciary obligations to BNSF or its stockholders; provided
further, that BNSF shall give CN at least five business days' written notice
prior to making any public announcement or other dissemination of any
withdrawal, modification or change of the recommendation of BNSF's board of
directors (the "BNSF Five Business Day Window"). Regardless of whether BNSF's

stockholders regarding the adoption of this Agreement or the approval of the
transactions contemplated by this Agreement, BNSF shall as promptly as

         Replacement Option shall otherwise be unchanged from those of the BNSF
         Option from which it was converted, and any document or agreement
         previously evidencing such BNSF Option shall thereafter evidence and be
         deemed to evidence such Newco Replacement Option.

                    (iv) Each share of capital stock of Merger Sub issued and
         outstanding immediately prior to the Merger Effective Time shall be
         converted into one share of common stock of the Surviving Corporation,
         and the Surviving Corporation shall thereby become a wholly owned
         Subsidiary of Newco.

                    (v) Each share of capital stock of Newco issued and
         outstanding immediately prior to the Merger Effective Time shall no
         longer be outstanding, shall be canceled and retired without payment of
         any consideration therefor, and shall cease to exist.

         (d) The certificate of incorporation of BNSF shall be amended in the
Merger to read in its entirety as set forth on Exhibit I and, as so amended,
shall be the certificate of incorporation of the Surviving Corporation until
amended in accordance with applicable Law. The by-laws of BNSF shall be amended
in the Merger to read in their entirety as set forth on Exhibit J and, as so
amended, shall be the by-laws of the Surviving Corporation until amended in
accordance with applicable Law.

         (e) The initial directors and officers of the Surviving Corporation
shall consist of the directors and officers of Merger Sub immediately prior to
the Merger Effective Time.

         2.5 Surrender of and Payment for BNSF Common Shares. (a) Prior to the
Merger Effective Time, CN and BNSF shall jointly appoint an agent (the "Exchange
Agent") for the purpose of exchanging certificates formerly representing BNSF
Common Shares as provided in

                                       12

Section 2.4(c). At the Arrangement Effective Time and in a manner consistent
with applicable Law, Newco and CN shall jointly cause to be deposited with the
Exchange Agent Newco Stapled Unit certificates representing the aggregate number
of Newco Common Shares and the aggregate number of CN Voting Shares to be paid
in respect of the BNSF Common Shares (such Newco Common Shares and CN Voting
Shares or, where appropriate, a portion thereof, the "BNSF Merger Consideration"
). Promptly after the Merger Effective Time, BNSF and CN shall cause the
Exchange Agent to send to each holder of BNSF Common Shares at the Merger
Effective Time a letter of transmittal for use in such exchange, which shall
specify that the delivery shall be effected, and risk of loss and title shall
pass, only upon proper delivery of the certificates representing BNSF Common
Shares to the Exchange Agent.

         (b) Each holder of BNSF Common Shares that have been converted into the
right to receive Newco Stapled Units, upon surrender to the Exchange Agent of a
certificate or certificates representing such BNSF Common Shares, together with
a properly completed letter of transmittal covering such BNSF Common Shares,
shall be entitled to receive the BNSF Merger Consideration payable in respect of
such BNSF Common Shares. Until so surrendered, each such certificate shall,
after the Merger Effective Time, represent for all purposes only the right to
receive such BNSF Merger Consideration.

         (c) If any portion of the BNSF Merger Consideration is to be paid to a
Person other than the registered holder of the BNSF Common Shares represented by
the certificate or certificates surrendered in exchange therefor, it shall be a
condition to such payment that the certificate or certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the Person requesting such payment shall pay to the Exchange Agent any transfer
or other Taxes required as a result of such payment to a Person other than the
registered holder of such BNSF Common Shares or establish to the satisfaction of
the Exchange Agent that such Tax has been paid or is not payable.

         (d) After the Merger Effective Time, there shall be no further
registration of transfers of BNSF Common Shares. If, after the Merger Effective
Time, certificates representing BNSF Common Shares are presented to the
Surviving Corporation, they shall be canceled and exchanged for the BNSF Merger
Consideration in accordance with the procedures set forth in this Section 2.5.

         (e) Any portion of the BNSF Merger Consideration deposited with the
Exchange Agent pursuant to this Section 2.5 that remains unclaimed by the
holders of BNSF Common Shares twelve months after the Merger Effective Time
shall be returned to Newco, upon demand, and any such holder who has not
exchanged his BNSF Common Shares for BNSF Merger Consideration in accordance
with this Section 2.5 prior to that time shall thereafter look only to Newco for
his claim for BNSF Merger Consideration and any dividends or distributions with
respect to Newco Common Shares. Notwithstanding the foregoing, Newco shall not
be liable to

                                       13


<PAGE>



any holder of BNSF Common Shares for any amount paid to a public official
pursuant to applicable abandoned property Laws.

         (f) No dividends or other distributions with respect to Newco Common
Shares shall be paid to the holder of any unsurrendered certificates formerly
representing BNSF Common Shares until such certificates are surrendered as
provided in this Section 2.5. Upon such surrender, there shall be paid, without
interest, to the Person in whose name the Newco Stapled Unit certificates
representing the BNSF Merger Consideration into which such BNSF Common Shares
were converted are registered (i) all dividends and other distributions in
respect of Newco Common Shares that are payable on a date subsequent to, and the
record date for which occurs at or after, the Merger Effective Time and (ii) all
dividends or other distributions in respect of BNSF Common Shares that are
payable on a date subsequent to, and the record date for which occurs before,
the Merger Effective Time.

         2.6 Interim Order. The notice of motion for the application referred to
in Section 2.1(a) shall request that the Interim Order provide (i) for the class
of Persons to whom notice is to be provided in respect of the Arrangement and
the CN Stockholder Meeting and for the manner in which such notice is to be
provided; (ii) that the requisite approval for the Arrangement Resolution shall
be two-thirds of the votes cast on the Arrangement Resolution by holders of CN
Common Stock and holders of CN Options voting together as a single class present
in person or by proxy at the CN Stockholder Meeting; and (iii) for the grant of
the Dissent Rights.

         2.7 The Arrangement. The Arrangement shall provide that, and the
parties covenant to take such steps as are necessary to ensure that, commencing
at the Arrangement Effective Time, the following shall occur and shall be deemed
to occur in the following order:

         (a) The authorized share capital of CN shall be reorganized by the
creation of the following three classes of shares in the capital of CN:

                    (i) a class of shares, designated as CN Voting Shares, the
         authorized number of which shall be unlimited;

                    (ii) a class of shares, designated as CN Exchangeable
         Shares, the authorized number of which shall be unlimited; and

                    (iii) a class of shares, designated as CN Limited Voting
         Equity Shares, the authorized number of which shall be unlimited.

                                       14


<PAGE>



         (b) Each outstanding CN Common Share shall be changed into a number of
CN Voting Shares equal to the Exchange Ratio and a number of CN Exchangeable
Shares equal to the Exchange Ratio.

         (c) Simultaneously with the change in share capital under Section
2.7(b), each CN Exchangeable Share to which the holder of a CN Common Share is
entitled and with respect to which such holder has elected, in a duly completed
and timely submitted letter of transmittal and election form, to transfer to
Newco for a Newco Common Share (the CN Exchangeable Share with respect to which
such election was made, a "Newco Elected Exchangeable Share") shall be
transferred by the holder thereof, without any further act or formality on such
holder's part, to Newco in exchange for one Newco Common Share issued by Newco.
Notwithstanding the foregoing, each holder of CN Common Shares who is not a
resident of Canada for purposes of the Income Tax Act (Canada) shall be deemed
to have elected to exchange all of the CN Exchangeable Shares issuable to such
holder pursuant to the Arrangement for Newco Common Shares and the CN
Exchangeable Shares to which such holder is entitled shall be deemed for all
purposes to be Newco Elected Exchangeable Shares, except where and to the extent
that such holder specifically elects in a duly completed and timely submitted
letter of transmittal and election form not to have such exchange occur. CN and
BNSF may jointly determine that such transfer and exchange shall be made to and
with NAR Subco rather than Newco.

         (d) Simultaneously with the change in share capital under Section
2.7(b) and the transfer to Newco and exchange under Section 2.7(c) of the Newco
Elected Exchangeable Shares, each Newco Elected Exchangeable Share shall be
converted into one CN Limited Voting Equity Share.

         (e) Simultaneously with the change in share capital under Section
2.7(b), the transfer to Newco and exchange under Section 2.7(c) of the Newco
Elected Exchangeable Shares and the conversion under Section 2.7(d) of the Newco
Elected Exchangeable Shares, Newco shall and shall be deemed to have subscribed
for and agreed to purchase and CN shall issue and sell to Newco one (1) CN
Limited Voting Equity Share upon payment by Newco to CN of a sum equal to the
closing trading price, per share, of the CN Common Shares on The Toronto Stock
Exchange on the trading day which is two days prior to the Arrangement Effective
Date divided by the Exchange Ratio. CN and BNSF may jointly determine that such
issuance shall be made to NAR Subco rather than Newco.

         (f) All holders of Newco Common Shares, other than those issued
pursuant to the exchange provided for in Section 2.7(c), shall be deemed to have
subscribed for and agreed to purchase at a purchase price of $0.05 per share, or
such other amount as to which the parties may agree, and CN shall issue to each
such holder of Newco Common Shares, one (1) CN Voting Share for each Newco
Common Share so held upon payment by Newco to CN of the aggregate subscription
price therefor.

                                       15


<PAGE>



         (g) Newco shall issue to and deposit with the Trustee the Special
Voting Share, in consideration of the payment to Newco of $0.05 by CN, to be
thereafter held of record by the Trustee as trustee for and on behalf of, and
for the use and benefit of, the holders of the CN Exchangeable Shares in
accordance with the Voting and Exchange Trust Agreement.

         (h) Each CN Option shall be exchanged for an option (a "CN Replacement
Option") to purchase that number of Newco Stapled Units equal to the product of
the Exchange Ratio multiplied by the number of CN Common Shares subject to such
CN Option immediately prior to the Arrangement Effective Time. Each CN
Replacement Option shall provide for an exercise price per Newco Stapled Unit
equal to the exercise price per CN Common Share of such CN Option immediately
prior to the Arrangement Effective Time divided by the Exchange Ratio. If the
foregoing calculation results in a CN Replacement Option being exercisable for a
fraction of a Newco Stapled Unit, then the number of Newco Stapled Units subject
to such CN Replacement Option shall be rounded up to the next whole number of
Newco Stapled Units. The term to expiry, conditions to and manner of exercising,
vesting schedule, and all other terms and conditions of such CN Replacement
Option shall otherwise be unchanged from those of the CN Option for which it was
exchanged, and any document or agreement previously evidencing such CN Option
shall thereafter evidence and be deemed to evidence such CN Replacement Option.

         (i) The authorized share capital of CN shall be amended by the
elimination of the CN Common Shares as a class of authorized shares.

         2.8 Board of Directors; Management. (a) Immediately prior to the Merger
Effective Time, the parties shall cause the board of directors of CN and the
board of directors of Newco, respectively, to be identical and composed of
fifteen members, six of whom shall be designated by BNSF, six of whom shall be
designated by CN and three of whom shall be jointly designated by agreement
between BNSF and CN. Unless BNSF agrees otherwise, all of CN's designees to the

Canadians, as defined in the CBCA. The six BNSF designees are: John J. Burns,
Jr.; Robert D. Krebs; Roy S. Roberts; J. Steven Whisler; Edward E. Whitacre,

unwilling to serve as directors at the time of Closing, replacements shall be
selected in accordance with the first two sentences of this Section 2.8(a).

         (b) At the Closing, the parties shall cause the following officers of

capacity. The remaining officers of CN and Newco to be appointed to office at
the Closing shall include representatives of both CN and BNSF and shall be
agreed on by the boards of directors of Newco and CN to take offices at the
Closing after receiving advice from the Chief Executive Officer of Newco and CN
to take offices at the Closing, after consultation with the Chairman of Newco
and CN to take offices at the Closing.

         2.9 Head Office. The head office of each of CN and Newco following the
Closing shall be situated in the Montreal Urban Community, Quebec, Canada.

         2.10 Withholding Rights. Each of CN, BNSF, Newco and the Surviving
Corporation shall be entitled to deduct and withhold from the consideration
otherwise payable to any Person pursuant to this Article II such amounts as it
is required to deduct and withhold with respect to the making of such payment
under any provision of applicable Law. Any amounts so withheld shall be treated
for all purposes of this Agreement as having been paid to the holder of CN
Common Shares or BNSF Common Shares, as the case may be, in respect of which
such deduction and withholding was made.

         2.11 The Closing. Unless otherwise mutually agreed in writing, the
closing of the transactions contemplated by this Agreement (the "Closing") shall
take place at 9:00 a.m., Chicago time, at the offices of Mayer, Brown & Platt,

                                   ARTICLE III

                      REPRESENTATIONS AND WARRANTIES OF CN

         Except as set forth in the corresponding sections or subsections of the
disclosure letter, dated the date of this Agreement, delivered by CN to BNSF
(the "CN Disclosure Letter"), CN represents and warrants to BNSF as follows:

         3.1 Corporate Existence and Power. CN is a corporation duly
incorporated, validly existing and in good standing under the Laws of Canada,
and has all corporate power and all material governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted. CN is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified,
individually or in the aggregate, would not be reasonably likely to have a
Material Adverse Effect on CN. Prior to the date of this Agreement, CN has made
available to BNSF true and complete copies of CN's constitutive documents, each
as amended to date, and such constitutive documents are in full force and
effect.

         3.2 Corporate Authorization. The execution, delivery and performance of
this Agreement and the Stock Option Agreements by CN and the consummation by CN
of the transactions contemplated hereby and thereby are within CN's corporate
powers and, except as set forth in the next sentence, have been duly authorized
by all necessary corporate action. The affirmative vote of two-thirds of the
votes cast on the Arrangement Resolution by holders of CN Common Shares and the
holders of CN Options voting together as a single class is the only vote of any
class or series of CN capital stock necessary to consummate the Arrangement.
This Agreement has been duly executed and delivered by CN and constitutes its
legal, valid and binding obligation, enforceable against it in accordance with
its terms, subject to bankruptcy, insolvency and other applicable Laws affecting
creditors' rights generally and general principles of equity.

         3.3 Governmental Authorization. The execution, delivery and performance
by CN of this Agreement and the Stock Option Agreements and the consummation by
CN of the transactions contemplated hereby and thereby require no action by or
in respect of, or filing with, any Governmental Entity other than (i) any
approvals required by the Interim Order; (ii) the Final Order; (iii) filings
with the Director under the CBCA; (iv) compliance with any applicable
requirements of the HSR Act and the Competition Act; (v) compliance with any
applicable requirements relating to approval of the transactions contemplated by
this Agreement by the Surface Transportation Board (the "STB"); (vi) compliance
with any applicable requirements of the 1933 Act, the 1934 Act and the
Securities Act; (vii) compliance with any applicable United States "blue sky" or
Canadian provincial securities Laws; (viii) immaterial actions or filings
relating to ordinary operational matters; (ix) approval by The Toronto Stock
Exchange of the

                                       18


<PAGE>



grant of the option by CN to BNSF under the CN Stock Option Agreement and the
issuance of CN Common Shares thereunder and (x) compliance with any applicable
requirements of the Defense Production Act of 1950, as amended (commonly known
as Exon-Florio).

         3.4 Non-Contravention. The execution, delivery and performance by CN of
this Agreement and the Stock Option Agreements and the consummation by CN of the
transactions contemplated hereby and thereby do not and will not (except in the
case of clauses (ii), (iii) and (iv) of this Section 3.4, for any such matters
that individually or in the aggregate would not be reasonably likely to have a
Material Adverse Effect on CN) (i) contravene or conflict with CN's constitutive
documents; (ii) assuming compliance with the matters referred to in Section 3.3,
contravene or conflict with, or constitute a violation of, any provision of any
Law binding upon or applicable to CN or any of its Subsidiaries; (iii)
constitute a default under, or give rise to a right of termination, cancellation
or acceleration of, any right or obligation of CN or any of its Subsidiaries or
to a loss of any benefit to which CN or any of its Subsidiaries is entitled
under any provision of any agreement, contract or other instrument binding upon
CN or any of its Subsidiaries, or any license, franchise, permit or other
similar authorization held by CN or any of its Subsidiaries; or (iv) result in
the creation or imposition of any Lien on any asset of CN or any of its
Subsidiaries.

         3.5 Capitalization. (a) The authorized capital stock of CN consists of
(i) an unlimited number of CN Common Shares, (ii) an unlimited number of Class A
Preferred Shares ("CN Class A Preferred Shares"), and (iii) an unlimited number
of Class B Preferred Shares, no par value ("CN Class B Preferred Shares"). As of
December 15, 1999, there were outstanding (i) 202,270,686 CN Common Shares, (ii)
no CN Class A Preferred Shares, (iii) no CN Class B Preferred Shares, and (iv)
CN Options to purchase an aggregate of 8,473,402 CN Common Shares (of which CN
Options to purchase an aggregate of approximately 4,072,616 CN Common Shares
were exercisable). All outstanding shares of CN's capital stock have been duly
authorized and validly issued and are fully paid and nonassessable. Except as
set forth in this Section 3.5 and except for the 5.25% Convertible Preferred
Securities due June 30, 2029 of CN or as contemplated by Section 6.1, and except
for the exercise of CN Options outstanding on December 15, 1999, or issued since
that date in accordance with Section 6.1, there are outstanding (x) no shares of
capital stock or other voting securities of CN, (y) no securities of CN or any
of its Subsidiaries convertible into or exchangeable for shares of capital stock
or voting securities of CN and (z) no options or other rights to acquire from CN
or any of its Subsidiaries, and no obligation of CN or any of its Subsidiaries
to issue, any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of CN (the items in clauses
(x), (y) and (z) being referred to collectively as the "CN Securities"). There
are no outstanding obligations of CN or any of its Subsidiaries to repurchase,
redeem or otherwise acquire any CN Securities, except for the transactions
contemplated by this Agreement.

                                       19


<PAGE>



         (b) As of the date of this Agreement, there are no outstanding bonds,
debentures, notes or other indebtedness of CN having the right to vote (or
convertible into or exercisable for CN Securities having the right to vote) on
any matters upon which holders of CN Common Stock may vote (collectively, the
"CN Voting Debt").

         3.6 Material Subsidiaries. Each of CN's Material Subsidiaries has been
duly incorporated or formed under all applicable Laws, is validly existing and
in good standing under the Laws of its jurisdiction and has full corporate or
legal power and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted. Each of CN's
Material Subsidiaries is duly qualified to do business and is in good standing
in each jurisdiction where the character of the property owned or leased by it
or the nature of its activities makes such qualification necessary, except for
those jurisdictions where the failure to be so qualified, individually or in the
aggregate, would not be reasonably likely to have a Material Adverse Effect on
CN. All of the outstanding shares and other ownership interests of CN's Material
Subsidiaries that are held directly or indirectly by CN are validly issued,
fully paid and nonassessable; all such shares and other ownership interests are
owned directly or indirectly by CN, free and clear of all material Liens and
free of any other limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests). Other than those obligations identified in Section 3.6 of
the CN Disclosure Letter, there are no outstanding (i) securities of CN or any
of its Subsidiaries convertible into or exchangeable for shares of capital stock
or other voting securities or ownership interests in any Subsidiary of CN or
(ii) options or other rights to acquire from CN or any of its Subsidiaries, and
no other obligation of CN or any of its Subsidiaries to issue, any capital stock
or voting securities or other ownership interests in, or any securities
convertible into or exchangeable for any capital stock, voting securities or
ownership interests in, any Subsidiary of CN (the capital stock of each
Subsidiary of CN, together with the items in clauses (i) and (ii), being
referred to collectively as the "CN Subsidiary Securities"). There are no
outstanding obligations of CN or any Subsidiary of CN to repurchase, redeem or
otherwise acquire any outstanding CN Subsidiary Securities.

         3.7 Canadian Securities Filings and SEC Filings. CN has filed with the
Canadian Securities Regulators and the SEC true and complete copies of all
forms, reports, schedules, statements and other documents required to be filed
by it since January 1, 1997 (such forms, reports, schedules, statements and
other documents, including any financial statements or other documents,
including any schedules included therein, are referred to as the "CN Reports").
Each such CN Report filed pursuant to the 1934 Act at the time filed (i) did not
contain any untrue statement of a material fact necessary to make the statements
made therein, in light of the circumstances in which they were made, not
misleading and (ii) complied in all material respects with all other
requirements of applicable securities Laws. Each such CN Report filed pursuant
to the 1933 Act at the time declared effective (i) did not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the

                                       20


<PAGE>



statements therein not misleading and (ii) complied in all material respects
with all other requirements of applicable securities Laws. CN has not filed any
confidential material change report with any Canadian Securities Regulator or
any other securities authority or regulator or any securities exchange or other
self-regulatory authority that, as of the date of this Agreement, remains
confidential.

         3.8 Financial Statements. The audited consolidated financial statements
and unaudited consolidated interim financial statements of CN included in the CN
Reports fairly present, in conformity with Canadian GAAP or GAAP, as applicable,
applied on a consistent basis (except as may be indicated in the notes thereto),
the consolidated financial position of CN and its consolidated Subsidiaries as
of the dates thereof and their consolidated results of operations and cash flows
for the periods then ended (subject to normal year-end adjustments in the case
of the unaudited consolidated interim financial statements).

         3.9 No Material Adverse Changes. Except as contemplated by this
Agreement or as publicly disclosed prior to the date of this Agreement, since
December 31, 1998, CN and the CN Material Subsidiaries have conducted their
business in the ordinary course consistent with past practice and there has not
been (i) any event, occurrence or development of a state of circumstances or
facts that has had or reasonably could be expected to have a Material Adverse
Effect on CN (other than as a result of changes in conditions, including
economic or political developments, applicable to the railroad industry in
general or any changes in the economy or securities markets in general) or (ii)
any declaration, setting aside or payment of any dividend or other distribution
with respect to any shares of CN capital stock.

         3.10 Undisclosed Material Liabilities. Except for (i) liabilities
reflected in the CN Reports and (ii) liabilities incurred in the ordinary course
of business of CN and its Subsidiaries consistent with past practice subsequent
to December 31, 1998, CN and its Subsidiaries have no liabilities that would
reasonably be expected to have a Material Adverse Effect on CN and there is no
existing condition or set of circumstances that would be reasonably likely to
result in such a liability; provided, however, that this representation does not
cover, and shall not be deemed to be breached as a result of, any such liability
that results primarily from a Customary Action.

         3.11 Litigation. Except as set forth in the CN Reports, (i) there is no
action, suit, investigation or proceeding (or any basis therefor) pending
against or, to the knowledge of CN, threatened against or affecting CN or any of
its Subsidiaries or any of their respective properties before any court or
arbitrator or any Governmental Entity where there is a reasonable probability of
a determination adverse to CN or any of its Subsidiaries that would be
reasonably likely to have a Material Adverse Effect on CN, and (ii) as of the
date of this Agreement, there is no such action, suit, investigation or
proceeding that in any manner challenges or seeks to prevent, enjoin, alter or
materially delay the Arrangement or any of the other transactions contemplated
by this Agreement.

                                       21


<PAGE>




         3.12 Taxes. Except as set forth in the CN Reports or as would not
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on CN, (i) all Tax Returns, statements, reports and forms
(collectively, the "CN Returns") required to be filed with any taxing authority
or provided to any other Person as of the date of this Agreement by, or with
respect to, CN and its Subsidiaries have been filed or provided in accordance
with all applicable Laws; (ii) CN and its Subsidiaries have timely paid or
withheld all Taxes shown as due and payable on the CN Returns that have been so
filed or required to be withheld by CN or any of its Subsidiaries as of the date
of this Agreement and, as of the time of filing, the CN Returns were true,
complete and correct; (iii) CN and its Subsidiaries have made provision for all
Taxes payable by CN and its Subsidiaries for which no CN Return has yet been
filed or resulting from the final resolution of any controversy with any taxing
authority; (iv) the charges, accruals and reserves for Taxes with respect to CN
and its Subsidiaries reflected in the CN Reports are adequate under Canadian
GAAP or GAAP, as applicable, to cover the Tax liabilities accruing through the
date thereof; and (v) as of the date of this Agreement, there is no action,
suit, proceeding, investigation, audit or claim now proposed or pending against
or with respect to CN or any of its Subsidiaries in respect of any Tax where a
determination or decision against CN or any of its Subsidiaries is more probable
than not.

         3.13 Employee Matters. (a) Except as contemplated by this Agreement,
Section 3.13 of the CN Disclosure Letter identifies (i) each "employee benefit
plan," as defined in Section 3(3) of ERISA (other than multiemployer plans, as
defined in Section 3(37) of ERISA), and (ii) each employment, severance or other
similar contract, arrangement or policy and each retirement or deferred
compensation plan, stock plan, incentive compensation plan, vacation pay,
severance pay, bonus or benefit arrangement, insurance (including self-insured
arrangements) or hospitalization program, workers' compensation program,
disability program, supplemental unemployment program or fringe benefit
arrangement, whether maintained pursuant to contract or informal understanding,
that does not constitute an "employee benefit plan" (as defined in Section 3(3)
of ERISA), which, in the case of items described in both clauses (i) and (ii),
is maintained, administered or contributed to by CN or any of its ERISA
Affiliates or with respect to which CN or any of its ERISA Affiliates has any
liability (collectively, the "CN U.S. Employee Plans"). Except as contemplated
by this Agreement, Section 3.13 of the CN Disclosure Letter identifies each
bonus, deferred compensation, incentive compensation, share purchase, share
appreciation, share option, severance and termination pay, hospitalization, drug
and other medical benefits, life and other insurance, dental, disability, sick
leave, salary continuation, vacation, supplemental unemployment benefits,
profit-sharing, mortgage assistance, pension, retirement and supplemental
retirement plans, programs and agreements sponsored, maintained, contributed to
or required to be contributed to by CN for the benefit of any of the Canadian
Employees, whether or not insured (collectively, the "CN Canadian Employee
Plans" and, together with the CN U.S. Employee Plans, the "CN Employee Plans").
True and correct copies of each of the CN Employee Plans, all amendments
thereto, any written

                                       22


<PAGE>



interpretations thereof distributed to employees, and all contracts relating
thereto or the funding thereof, including all trust agreements, insurance
contracts, administration contracts, investment management agreements,
subscription and participation agreements, recordkeeping agreements and summary
plan descriptions, all as currently in effect, have been furnished or made
available to BNSF. CN has supplied or made available to BNSF an accurate
description of any CN Employee Plan that is not in written form. To the extent
applicable, true and correct copies of the three most recent annual reports
(Form 5500, including, if applicable, Schedule B thereto) prepared in connection
with any CN Employee Plan and the most recent actuarial valuation report
prepared in connection with any such plan have been furnished or made available
to BNSF.

         (b) The only CN Employee Plans that are subject to Title IV of ERISA
(the "CN Pension Plans") are identified as such in Section 3.13 of the CN
Disclosure Letter. The only CN Canadian Employee Plans that are registered
pension plans (the "CN Canadian Pension Plans") are identified as such in
Section 3.13 of the CN Disclosure Letter. No "accumulated funding deficiency,"
as defined in Section 412 of the Code, has been incurred with respect to any CN
Pension Plan, whether or not waived. To CN's knowledge, no "reportable event,"
within the meaning of Section 4043 of ERISA and the regulations promulgated
thereunder has occurred with respect to any CN Pension Plan, and no event
described in Section 4041 (other than a standard termination), 4042, 4062 or
4063 of ERISA has occurred in connection with any CN Pension Plan, other than a
reportable event for which the PBGC notice requirements have been waived or a
reportable event that would not be reasonably likely to have a Material Adverse
Effect on CN. No condition exists and no event has occurred that could
constitute grounds for termination of or the appointment of a trustee to
administer any CN Pension Plan under Section 4042 of ERISA and, to CN's
knowledge, neither CN nor any of its ERISA Affiliates has engaged in, or is a
successor or parent corporation to an entity that has engaged in, a transaction
for which CN or any of its ERISA Affiliates would have liability under Section
4069 or 4212(c) of ERISA. To CN's knowledge, nothing done or omitted to be done
and no transaction or holding of any asset under or in connection with any CN
Employee Plan has or will make CN or any of its ERISA Affiliates or any officer
or director of CN or any of its ERISA Affiliates subject to any liability under
Title I or Section 4071 of ERISA or liable for any Tax pursuant to Section 4975
or Chapter 43, 47, 68 or 100 of the Code that would be reasonably likely to have
a Material Adverse Effect on CN.

         (c) Each CN Employee Plan that is intended to be qualified under
Section 401(a) of the Code is the subject of a favorable determination letter
issued by the IRS covering all changes in Law and changes to the form of the CN
Employee Plan for which the remedial amendment period (as described in
regulations issued under Section 401(b) of the Code) has not expired. Each CN
Employee Plan has been maintained in substantial compliance with its terms and
with the requirements prescribed by any and all Laws, including ERISA and the
Code, that are applicable to such CN Employee Plan.

                                       23

         (d) None of the payments contemplated by the CN Employee Plans or any
other contract, plan or arrangement covering any employee or former employee of
CN or any of its ERISA Affiliates and arising solely as a result of the
transactions contemplated by this Agreement would, in the aggregate, constitute
excess parachute payments as defined in Section 280G of the Code (without regard
to subsection (b)(4) thereof) or provide for payments that exceed the
deductibility limitations of Section 162(m) of the Code.

         (e) Except for obligations arising pursuant to any collective
bargaining agreements, to the knowledge of CN and its Subsidiaries, no condition
exists that would prevent CN or any of its Subsidiaries from amending or
terminating any CN Employee Plan providing health or medical benefits in respect
of any active or former employees of CN or any of its Subsidiaries.

         (f) There has been no amendment or interpretation by CN or any of its
ERISA Affiliates relating to, or change in employee participation or coverage
under any CN Employee Plan that would increase materially the expense of
maintaining such CN Employee Plan above the level of expense incurred in respect
thereof for the fiscal year ended December 31, 1998.

         (g) To the extent applicable, each CN Employee Plan that constitutes a
"group health plan" (as defined in Section 6071(1) of ERISA or Section
4980B(g)(2) of the Code), including any plans of current or former affiliates
that must be taken into account under Sections 4980B and 414(t) of the Code or
Section 601 of ERISA, has been operated in substantial compliance with
applicable Law, including the group health plan continuation coverage
requirements of Section 4980B of the Code and Section 601 of ERISA and the
requirements of Chapter 100 of the Code.

         (h) There are no actions, suits or claims (other than routine claims
for benefits) pending or, to CN's knowledge, threatened involving any CN
Employee Plan or the assets thereof, and no facts exist that could give rise to
any such actions, suits or claims (other than routine claims for benefits).

         (i) With respect to each employee pension benefit plan (as defined in
Section 3(2) of ERISA) that is a multiemployer plan with respect to which CN or
any of its ERISA Affiliates may have any liability (including any liability
attributable to a current or former member of CN's or any of its ERISA
Affiliates' "controlled group" (as defined in Section 4001(a)(14) of ERISA)),
(i) all contributions have been made as required by the terms of the plans, the
terms of any collective bargaining agreements and applicable Law, (ii) neither
CN nor any of its ERISA Affiliates has withdrawn, partially withdrawn or
received any notice of any claim or demand for withdrawal liability or partial
withdrawal liability that would be reasonably likely to have a Material Adverse
Effect on CN and (iii) neither CN nor any of its ERISA Affiliates has received
any notice that any such plan is in reorganization, that increased contributions
may be required to avoid a reduction in plan benefits or the imposition of any
excise Tax, that any such plan is or

                                       24


<PAGE>



has been funded at a rate less than that required under Section 412 of the Code
or that any plan is or may become insolvent.

         (j) As of December 31, 1998, the Expected Postretirement Benefit
Obligation (as defined in Statement of Financial Accounting Standards No. 106)
in respect of postretirement health and medical benefits for current and former
employees of CN or any of its Subsidiaries calculated by CN's actuary using
reasonable actuarial assumptions was $65,000,000.

         (k) Neither CN's board of directors nor any committee thereof has
adopted a resolution or taken any other action to determine or declare that any
of the transactions contemplated by this Agreement will constitute a change of
control for purposes of any CN Employee Plan.

         (l) The transactions contemplated by this Agreement will not trigger
any obligation to fund the benefits under any CN Employee Plan.

         3.14 Finders' Fees. Except for Salomon Smith Barney Inc.; The Beacon
Group Capital Services Group, LLC, and Nesbitt Burns Inc. copies of whose
engagement agreements have been provided to BNSF, there is no investment banker,
broker, finder or other intermediary that has been retained by or is authorized
to act on behalf of CN or any of its Subsidiaries who might be entitled to any
fee or commission from BNSF or any of its affiliates in connection with the
transactions contemplated by this Agreement.

         3.15 Environmental Matters. Except as set forth in the CN Reports or
otherwise previously disclosed in writing by CN to BNSF, there are no
Environmental Liabilities of CN that, individually or in the aggregate, have had
or would be reasonably likely to have a Material Adverse Effect on CN.

         3.16 Compliance with Laws. Except as publicly disclosed and except for
any matter that would not be reasonably likely to have a Material Adverse Effect
on CN, neither CN nor any of its Subsidiaries is in violation of, or has
violated, any applicable provision of any Law.

         3.17 Year 2000 Compliance. CN and its Subsidiaries are Year 2000
Compliant, and there are no foreseeable material expenses or other material
liabilities associated with the process of CN and its Subsidiaries becoming Year
2000 Compliant.

                                   ARTICLE IV

                     REPRESENTATIONS AND WARRANTIES OF BNSF



                                       25


<PAGE>



         Except as set forth in the corresponding sections or subsections of the
disclosure letter, dated the date of this Agreement, delivered by BNSF to CN
(the "BNSF Disclosure Letter"), BNSF represents and warrants to CN as follows:

         4.1 Corporate Existence and Power. BNSF is a corporation duly
incorporated, validly existing and in good standing under the Laws of the State
of Delaware, and has all corporate power and all material governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted. BNSF is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where the failure to be so qualified,
individually or in the aggregate, would not be reasonably likely to have a
Material Adverse Effect on BNSF. Prior to the date of this Agreement, BNSF has
made available to CN true and complete copies of its constitutive documents,
each as amended to date, and such constitutive documents are in full force and
effect.

         4.2 Corporate Authorization. The execution, delivery and performance of
this Agreement and the Stock Option Agreements by BNSF and the consummation by
BNSF of the transactions contemplated hereby and thereby are within BNSF's
corporate powers and, except as set forth in the next sentence, have been duly
authorized by all necessary corporate action. The affirmative vote of the
holders of at least a majority of the outstanding BNSF Common Shares entitled to
vote on the approval and adoption of this Agreement is the only vote of any
class or series of BNSF capital stock necessary to consummate the Merger. This
Agreement has been duly executed and delivered by BNSF and constitutes its
legal, valid and binding obligation, enforceable against BNSF in accordance with
its terms, subject to bankruptcy, insolvency and other applicable Laws affecting
creditors' rights generally and general principles of equity.

         4.3 Governmental Authorization. The execution, delivery and performance
by BNSF of this Agreement and the Stock Option Agreements and the consummation
by BNSF of the transactions contemplated hereby and thereby require no action by
or in respect of, or filing with, any Governmental Entity other than (i)
compliance with any applicable requirements of the HSR Act and the Competition
Act; (ii) compliance with any applicable requirements relating to approval of
the transactions contemplated by this Agreement by the STB; (iii) compliance
with any applicable requirements of the Securities Act, the 1933 Act and the
1934 Act; (iv) compliance with any applicable United States "blue sky" or
Canadian provincial securities Laws; and (v) immaterial actions or filings
relating to ordinary operational matters and filings with the United States
Federal Communications Commission with respect to radio licenses held by BNSF
and its Subsidiaries.

                                       26


<PAGE>



         4.4 Non-Contravention. The execution, delivery and performance by BNSF
of this Agreement and the Stock Option Agreements and the consummation by BNSF
of the transactions contemplated hereby and thereby do not and will not (except
in the case of clauses (ii), (iii) and (iv) of this Section 4.4, for any such
matters that individually or in the aggregate would not be reasonably likely to
have a Material Adverse Effect on BNSF) (i) contravene or conflict with its
constitutive documents; (ii) assuming compliance with the matters referred to in
Section 4.3, contravene or conflict with, or constitute a violation of, any
provision of any Law binding upon or applicable to BNSF or any of its
Subsidiaries; (iii) constitute a default under, or give rise to a right of
termination, cancellation or acceleration of, any right or obligation of BNSF or
any of its Subsidiaries or to a loss of any benefit to which BNSF or any of its
Subsidiaries is entitled under any provision of any agreement, contract or other
instrument binding upon BNSF or any of its Subsidiaries, or any license,
franchise, permit or other similar authorization held by BNSF or any of its
Subsidiaries; or (iv) result in the creation or imposition of any Lien on any
asset of BNSF or any of its Subsidiaries.

         4.5 Capitalization. (a) The authorized capital stock of BNSF consists
of (i) six hundred million (600,000,000) BNSF Common Shares, (ii) twenty-five
million (25,000,000) shares of Preferred Stock, par value $0.01 per share ("BNSF
Preferred Stock") of which 6,900,000 shares were designated as 6 1/4% Cumulative
Convertible Preferred Stock, Series A, and 3,000,000 shares are being designated
Junior Participating Preferred Stock, Series B, in connection with the BNSF
Shareholder Rights Plan, and (iii) fifty million (50,000,000) shares of Class A
Preferred Stock, par value $0.01 per share ("BNSF Class A Preferred Stock"). As
of December 15, 1999, there were outstanding (i) 454,945,828 BNSF Common Shares
and 29,970,990 BNSF Common Shares were held in treasury, (ii) no shares of BNSF
Preferred Stock, (iii) no shares of BNSF Class A Preferred Stock, and (iv) BNSF
Options to purchase an aggregate of 30,048,057 BNSF Common Shares (of which,
BNSF Options to purchase an aggregate of 20,602,140 BNSF Common Shares were
exercisable). All outstanding shares of BNSF's capital stock have been duly
authorized and validly issued and are fully paid and nonassessable. Except as
set forth in this Section 4.5 or as contemplated by Section 7.1, and except for
the exercise of BNSF Options outstanding on December 15, 1999, or issued since
that date in accordance with Section 7.1, there are outstanding (x) no shares of
capital stock or other voting securities of BNSF, (y) no securities of BNSF or
any of its Subsidiaries convertible into or exchangeable for shares of capital
stock or voting securities of BNSF and (z) no options or other rights to acquire
from BNSF or any of its Subsidiaries, and no obligation of BNSF or any of its
Subsidiaries to issue, any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of BNSF
(the items in clauses (x), (y) and (z) being referred to collectively as the
"BNSF Securities"). There are no outstanding obligations of BNSF or any of its
Subsidiaries to repurchase, redeem or otherwise acquire any BNSF Securities,
except for the transactions contemplated by this Agreement.

                                       27


<PAGE>



         (b) As of the date of this Agreement, there are no outstanding bonds,
debentures, notes or other indebtedness of BNSF having the right to vote (or
convertible into or exercisable for BNSF Securities having the right to vote) on
any matters upon which holders of BNSF Common Stock may vote (collectively, the
"BNSF Voting Debt").

         4.6 Material Subsidiaries. Each of BNSF's Material Subsidiaries has
been duly incorporated or formed under all applicable Laws, is validly existing
and in good standing under the Laws of its jurisdiction and has full corporate
or legal power and all material governmental licenses, authorizations, consents
and approvals required to carry on its business as now conducted. Each of BNSF's
Material Subsidiaries is duly qualified to do business and is in good standing
in each jurisdiction where the character of the property owned or leased by it
or the nature of its activities makes such qualification necessary, except for
those jurisdictions where the failure to be so qualified, individually or in the
aggregate, would not be reasonably likely to have a Material Adverse Effect on
BNSF. All of the outstanding shares and other ownership interests of BNSF's
Material Subsidiaries that are held directly or indirectly by BNSF are validly
issued, fully paid and nonassessable; all such shares and other ownership
interests are owned directly or indirectly by BNSF, free and clear of all
material Liens and free of any other limitation or restriction (including any
restriction on the right to vote, sell or otherwise dispose of such capital
stock or other ownership interests). Other than those obligations identified in
Section 4.6 of the BNSF Disclosure Letter, there are no outstanding (i)
securities of BNSF or any of its Subsidiaries convertible into or exchangeable
for shares of capital stock or other voting securities or ownership interests in
any Subsidiary of BNSF or (ii) options or other rights to acquire from BNSF or
any of its Subsidiaries, and no other obligation of BNSF or any of its
Subsidiaries to issue, any capital stock, voting securities or other ownership
interests in, or any securities convertible into or exchangeable for any capital
stock voting securities or ownership interests in, any Subsidiary of BNSF (the
capital stock of each Subsidiary of BNSF, together with the items in clauses (i)
and (ii), being referred to collectively as the "BNSF Subsidiary Securities").
There are no outstanding obligations of BNSF or any Subsidiary of BNSF to
repurchase, redeem or otherwise acquire any outstanding BNSF Subsidiary
Securities.

         4.7 SEC Filings. BNSF has filed with the SEC true and complete copies
of all forms, reports, schedules, statements and other documents required to be
filed by it since January 1, 1997 (such forms, reports, schedules, statements
and other documents, including any financial statements or other documents,
including any schedules included therein, are referred to as the "BNSF
Reports"). Each such BNSF Report filed pursuant to the 1934 Act at the time
filed (i) did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading and (ii) complied in all material respects with all other
requirements of applicable securities Laws. Each such BNSF Report filed pursuant
to the 1933 Act at the time declared effective (i) did not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make

                                       28


<PAGE>



the statements therein not misleading and (ii) complied in all material respects
with all other requirements of applicable securities Laws. BNSF has not filed
any confidential report with the SEC or any other securities authority or
regulator or any securities exchange or other self-regulatory authority that, as
of the date of this Agreement, remains confidential.

         4.8 Financial Statements. The audited consolidated financial statements
and unaudited consolidated interim financial statements of BNSF included in the
BNSF Reports fairly present, in conformity with GAAP applied on a consistent
basis (except as may be indicated in the notes thereto), the consolidated
financial position of BNSF and its consolidated Subsidiaries as of the dates
thereof and their consolidated results of operations and cash flows for the
periods then ended (subject to normal year-end adjustments in the case of the
unaudited consolidated interim financial statements).

         4.9 No Material Adverse Changes. Except as contemplated by this
Agreement or as publicly disclosed prior to the date of this Agreement, since
December 31, 1998, BNSF and the BNSF Material Subsidiaries have conducted their
business in the ordinary course consistent with past practice and there has not
been (i) any event, occurrence or development of a state of circumstances or
facts that has had or reasonably could be expected to have a Material Adverse
Effect on BNSF (other than as a result of changes in conditions, including
economic or political developments, applicable to the railroad industry
generally or any changes in the economy or securities markets in general) or
(ii) any declaration, setting aside or payment of any dividend or other
distribution with respect to any shares of BNSF capital stock.

         4.10 Undisclosed Material Liabilities. Except for (i) liabilities
reflected in the BNSF Reports and (ii) liabilities incurred in the ordinary
course of business of BNSF and its Subsidiaries consistent with past practice
subsequent to December 31, 1998, BNSF and its Subsidiaries have no liabilities
that would reasonably be expected to have a Material Adverse Effect on BNSF and
there is no existing condition or set of circumstances that would be reasonably
likely to result in such a liability; provided, however, that this
representation does not cover, and shall not be deemed to be breached as a
result of, any such liability that results primarily from a Customary Action.

         4.11 Litigation. Except as set forth in the BNSF Reports, (i) there is
no action, suit, investigation or proceeding (or any basis therefor) pending
against or, to the knowledge of BNSF, threatened against or affecting BNSF or
any of its Subsidiaries or any of their respective properties before any court
or arbitrator or any Governmental Entity where there is a reasonable probability
of a determination adverse to BNSF or any of its Subsidiaries that would be
reasonably likely to have a Material Adverse Effect on BNSF, and (ii) as of the
date of this Agreement, there is no such action, suit, investigation or
proceeding that in any manner challenges or seeks to prevent, enjoin, alter or
materially delay the Arrangement or any of the other transactions contemplated
by this Agreement.

                                       29


<PAGE>




         4.12 Taxes. Except as set forth in the BNSF Reports or as would not
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on BNSF, (i) all Tax Returns, statements, reports and forms
(collectively, the "BNSF Returns") required to be filed with any taxing
authority or provided to any other Person as of the date of this Agreement by,
or with respect to, BNSF and its Subsidiaries have been filed or provided in
accordance with all applicable Laws; (ii) BNSF and its Subsidiaries have timely
paid or withheld all Taxes shown as due and payable on the BNSF Returns that
have been so filed or required to be withheld by BNSF or any of its Subsidiaries
as of the date of this Agreement and, as of the time of filing, the BNSF Returns
were true, complete and correct; (iii) BNSF and its Subsidiaries have made
provision for all Taxes payable by BNSF and its Subsidiaries for which no BNSF
Return has yet been filed or resulting from the final resolution of any
controversy with any taxing authority; (iv) the charges, accruals and reserves
for Taxes with respect to BNSF and its Subsidiaries reflected in the BNSF
Reports are adequate under GAAP to cover the Tax liabilities accruing through
the date thereof; and (v) as of the date of this Agreement, there is no action,
suit, proceeding, investigation, audit or claim now proposed or pending against
or with respect to BNSF or any of its Subsidiaries in respect of any Tax where a
determination or decision against BNSF or any of its Subsidiaries is more
probable than not.

         4.13 Employee Matters. (a) Except as contemplated by this Agreement,
Section 4.13 of the BNSF Disclosure Letter identifies (i) each "employee benefit
plan," as defined in Section 3(3) of ERISA (other than multiemployer plans, as
defined in Section 3(37) of ERISA), and (ii) each employment, severance or other
similar contract, arrangement or policy and each retirement or deferred
compensation plan, stock plan, incentive compensation plan, vacation pay,
severance pay, bonus or benefit arrangement, insurance (including self-insured
arrangements) or hospitalization program, workers' compensation program,
disability program, supplemental unemployment program or fringe benefit
arrangement, whether maintained pursuant to contract or informal understanding,
that does not constitute an "employee benefit plan" (as defined in Section 3(3)
of ERISA), which, in the case of items described in both clauses (i) and (ii),
is maintained, administered or contributed to by BNSF or any of its ERISA
Affiliates or with respect to which BNSF or any of its ERISA Affiliates has any
liability (collectively, the "BNSF Employee Plans"). True and correct copies of
each of the BNSF Employee Plans, all amendments thereto, any written
interpretations thereof distributed to employees, and all contracts relating
thereto or the funding thereof, including all trust agreements, insurance
contracts, administration contracts, investment management agreements,
subscription and participation agreements, recordkeeping agreements and summary
plan descriptions, all as currently in effect, have been furnished or made
available to CN, or were available upon request from BNSF. Any BNSF Employee
Plan that was not provided to CN (as designated in Section 4.13 of the BNSF
Disclosure Letter by an asterisk) is not material (using the definition of
"material" set forth in Section 1.1). BNSF has supplied or made available to CN
an accurate description of any BNSF Employee Plan that is not in written form.
To the extent applicable,

                                       30


<PAGE>



true and correct copies of the three most recent annual reports (Form 5500,
including, if applicable, Schedule B thereto) prepared in connection with any
BNSF Employee Plan and the most recent actuarial valuation report prepared in
connection with any such plan have been furnished or made available to CN.

         (b) The only BNSF Employee Plans that are subject to Title IV of ERISA
(the "BNSF Pension Plans") are identified as such in Section 4.13 of the BNSF
Disclosure Letter. No "accumulated funding deficiency," as defined in Section
412 of the Code, has been incurred with respect to any BNSF Pension Plan,
whether or not waived. To BNSF's knowledge, no "reportable event," within the
meaning of Section 4043 of ERISA and the regulations promulgated thereunder has
occurred with respect to any BNSF Pension Plan, and no event described in
Section 4041 (other than a standard termination), 4042, 4062 or 4063 of ERISA
has occurred in connection with any BNSF Pension Plan, other than a reportable
event for which the PBGC notice requirements have been waived or a reportable
event that would not be reasonably likely to have a Material Adverse Effect on
BNSF. No condition exists and no event has occurred that could constitute
grounds for termination of or the appointment of a trustee to administer any
BNSF Pension Plan under Section 4042 of ERISA and, to BNSF's knowledge, neither
BNSF nor any of its ERISA Affiliates has engaged in, or is a successor or parent
corporation to an entity that has engaged in, a transaction for which BNSF or
any of its ERISA Affiliates would have liability under Section 4069 or 4212(c)
of ERISA. To BNSF's knowledge, nothing done or omitted to be done and no
transaction or holding of any asset under or in connection with any BNSF
Employee Plan has or will make BNSF or any of its ERISA Affiliates or any
officer or director of BNSF or any of its ERISA Affiliates subject to any
liability under Title I or Section 4071 of ERISA or liable for any Tax pursuant
to Section 4975 or Chapter 43, 47 or 68 of the Code that would be reasonably
likely to have a Material Adverse Effect on BNSF.

         (c) Each BNSF Employee Plan that is intended to be qualified under
Section 401(a) of the Code is the subject of a favorable determination letter
issued by the IRS covering all changes in Law and changes to the form of the
BNSF Employee Plan for which the remedial amendment period (as described in
regulations issued under Section 401(b) of the Code) has not expired. Each BNSF
Employee Plan has been maintained in substantial compliance with its terms and
with the requirements prescribed by any and all Laws, including ERISA and the
Code, that are applicable to such BNSF Employee Plan.

         (d) None of the payments contemplated by the BNSF Employee Plans or any
other contract, plan or arrangement covering any employee or former employee of
BNSF or any of its ERISA Affiliates and arising solely as a result of the
transactions contemplated by this Agreement would, in the aggregate, constitute
excess parachute payments as defined in Section 280G of the Code (without regard
to subsection (b)(4) thereof) or provide for payments that exceed the
deductibility limitations of Section 162(m) of the Code.

                                       31

         (e) Except for obligations arising pursuant to any collective
bargaining agreements, to the knowledge of BNSF and its Subsidiaries, no
condition exists that would prevent BNSF or any of its Subsidiaries from
amending or terminating any BNSF Employee Plan providing health or medical
benefits in respect of any active or former employees of BNSF or any of its
Subsidiaries.

         (f) There has been no amendment or interpretation by BNSF or any of its
ERISA Affiliates relating to, or change in employee participation or coverage
under any BNSF Employee Plan that would increase materially the expense of
maintaining such BNSF Employee Plan above the level of expense incurred in
respect thereof for the fiscal year ended December 31, 1998.

         (g) To the extent applicable, each BNSF Employee Plan that constitutes
a "group health plan" (as defined in Section 6071(1) of ERISA or Section
4980B(g)(2) of the Code), including any plans of current or former affiliates
that must be taken into account under Sections 4980B and 414(t) of the Code or
Section 601 of ERISA, has been operated in substantial compliance with
applicable Law, including the group health plan continuation coverage
requirements of Section 4980B of the Code and Section 601 of ERISA and the
requirements of Chapter 100 of the Code.

         (h) There are no actions, suits or claims (other than routine claims
for benefits) pending or, to BNSF's knowledge, threatened involving any BNSF
Employee Plan or the assets thereof, and no facts exist that could give rise to
any such actions, suits or claims (other than routine claims for benefits).

         (i) With respect to each employee pension benefit plan (as defined in
Section 3(2) of ERISA) that is a multiemployer plan with respect to which BNSF
or any of its ERISA Affiliates may have any liability (including any liability
attributable to a current or former member of BNSF's or any of its ERISA
Affiliates' "controlled group" (as defined in Section 4001(a)(14) of ERISA)),
(i) all contributions have been made as required by the terms of the plans, the
terms of any collective bargaining agreements and applicable Law, (ii) neither
BNSF nor any of its ERISA Affiliates has withdrawn, partially withdrawn or
received any notice of any claim or demand for withdrawal liability or partial
withdrawal liability that would be reasonably likely to have a Material Adverse
Effect on BNSF and (iii) neither BNSF nor any of its ERISA Affiliates has
received any notice that any such plan is in reorganization, that increased
contributions may be required to avoid a reduction in plan benefits or the
imposition of any excise Tax, that any such plan is or has been funded at a rate
less than that required under Section 412 of the Code or that any plan is or may
become insolvent.

         (j) As of December 31, 1998, the Expected Postretirement Benefit
Obligation (as defined in Statement of Financial Accounting Standards No. 106)
in respect of postretirement

                                       32


<PAGE>



health and medical benefits for current and former employees of BNSF or any of
its Subsidiaries calculated by BNSF's actuary using reasonable actuarial
assumptions was approximately $232,000,000.

         (k) Neither BNSF's board of directors nor any committee thereof has
adopted a resolution or taken any other action to declare or determine that any
of the transactions contemplated by this Agreement will constitute a change in
control for the purposes of any BNSF Employee Plan.

         (l) The transactions contemplated by this Agreement will not trigger
any obligation to fund the benefits under any BNSF Employee Plan.

         4.14 Finders' Fees. Except for Goldman, Sachs & Co., a copy of whose
engagement agreement has been provided to CN, there is no investment banker,
broker, finder or other intermediary that has been retained by or is authorized
to act on behalf of BNSF or any of its Subsidiaries who might be entitled to any
fee or commission from BNSF or any of its affiliates in connection with the
transactions contemplated by this Agreement.

         4.15 Environmental Matters. Except as set forth in the BNSF Reports or
otherwise previously disclosed in writing by BNSF to CN, there are no
Environmental Liabilities of BNSF that, individually or in the aggregate, have
had or would be reasonably likely to have a Material Adverse Effect on BNSF.

         4.16 Takeover Statutes; Rights Plan. (a) BNSF's board of directors has
taken all necessary action to make Section 203 of the DGCL inapplicable to this
Agreement and the BNSF Stock Option Agreement and the transactions contemplated
hereby and thereby.

         (b) BNSF's board of directors has taken all necessary action to render
the rights issued pursuant to the terms of the BNSF Shareholder Rights Plan
inapplicable to the Merger, this Agreement and the transactions contemplated
hereby and thereby.

         4.17 Compliance with Laws. Except as publicly disclosed and except for
any matter that would not be reasonably likely to have a Material Adverse Effect
on BNSF, neither BNSF nor any of its Subsidiaries is in violation of, or has
violated, any applicable provision of any Law.

         4.18 Year 2000 Compliance. BNSF and its Subsidiaries are Year 2000
Compliant, and there are no foreseeable material expenses or other material
liabilities associated with the process of BNSF and its Subsidiaries becoming
Year 2000 Compliant.

Act or filed with Canadian Securities Regulators prepared in connection with
transactions contemplated by this Agreement shall contain any untrue statement
of a material fact or omit to state a material fact required to be stated in any
such document or necessary in order to make any information so furnished for use

under the 1933 Act or filed with Canadian Securities Regulators prepared in
connection with the transactions contemplated by this Agreement shall contain
any untrue statement of a material fact or omit to state a material fact
required to be stated in any such document or necessary in order to make any
information so furnished for use in any such document not misleading. Each party
shall promptly notify the other if at any time before or after the Closing it
becomes aware that any such information contains any untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements contained therein, in the case of such 1934 Act

and, in the case of such 1933 Act filings, not misleading.

         (g) Within two business days after the date of this Agreement, CN shall
prepare and file with The Toronto Stock Exchange a notice of the option granted
by CN to BNSF under the CN Stock Option Agreement and the proposed issuance of
CN Common Shares issuable upon the exercise of such option and shall use
reasonable best efforts to cause The Toronto Stock Exchange to accept such

         5.4 Access to Information. (a) Subject to any confidentiality
agreements or other confidentiality obligations binding upon any party or any of
such party's Subsidiaries, from the date of this Agreement until the Arrangement
Effective Time and except as prohibited by applicable Law, each party shall give
the other party, its counsel, financial advisors, auditors and other authorized
representatives full, reasonable access to the offices, properties, books and
records of such party and its Subsidiaries, shall furnish to the other party,
its counsel, financial advisors, auditors and other authorized representatives
such financial and operating data and other information as such Persons may
reasonably request and shall instruct such party's employees, counsel and
financial advisors to cooperate with the other party in its investigation of the
business of such party and its Subsidiaries; provided, however, that no
investigation pursuant



                                       36


<PAGE>



to this Section 5.4 shall affect any representation or warranty given by the
parties under this Agreement; and provided further, that access to certain

date access shall be granted to such information consistent with this Section
5.4 and subject to the terms of such order.

         (b) The parties acknowledge that certain information may be

         proceedings commenced or, to the best of such party's knowledge,
         threatened against, relating to or involving or otherwise affecting
         such party or any Subsidiary of such party that, if pending on the date
         of this Agreement, would have been required to have been disclosed
         pursuant to Section 3.11 or Section 4.11, as the case may be, that
         relate to the consummation of the transactions contemplated by this
         Agreement.

         5.6 Stock Exchange Listing. Each party shall use its reasonable best
efforts to have the Newco Common Shares and CN Voting Shares constituting the

Stapled Units approved for listing on The Toronto Stock Exchange.

         5.7 Public Announcements. The initial press release with respect to the
transactions contemplated by this Agreement shall be a joint press release.
Thereafter, the parties shall consult with each other before issuing any press

Agreement and, except as may be required by applicable Law or the requirements
of any securities exchange on which a party's securities are traded, will not
issue any such press release prior to such consultation.

                                       37


<PAGE>




         5.8 Further Assurances. At and after the Arrangement Effective Time,
the officers and directors of each party shall be authorized to execute and
deliver, in the name and on behalf of such party, any deeds, bills of sale,
assignments or assurances and to take and do, in the name and on behalf of such
party, any other actions and things necessary or desirable with respect to the
consummation of the transactions contemplated by this Agreement.

         5.9 Cooperation. Without limiting any party's obligation under any
other provision of this Agreement, each party shall together, or pursuant to an
allocation of responsibility to be agreed among the parties, coordinate and
cooperate (i) with respect to the timing of the BNSF Stockholder Meeting and the
CN Stockholder Meeting and shall use reasonable best efforts to hold such
meetings on the same day; (ii) in connection with the preparation of the
Circular, the Form S-4, the Form F-4, the Form S-3 and the Form S-8; (iii) in

with the consummation of the transactions contemplated by this Agreement; (iv)
in seeking any such actions, consents, approvals or waivers or making any such

         5.10 Closing Matters. Each party shall deliver at the Closing such
customary certificates, resolutions and other closing documents as may be
reasonably required by the other parties to this Agreement.

         5.11 Obligations of Newco. Each of CN and BNSF will take all actions
necessary to cause Newco to perform its obligations under this Agreement.
Without limiting the generality of the foregoing, CN, BNSF and Newco agree that:

         (a) immediately prior to the Merger Effective Time, Newco shall be a
corporation duly incorporated, validly existing and in good standing under the
Laws of Delaware and shall



                                       38


<PAGE>



have all corporate powers and all material governmental licenses,
authorizations, consents and approvals required to carry on the businesses of
BNSF as such businesses are now conducted;

         (b) at the Merger Effective Time, the performance by Newco of this
Agreement and the consummation by Newco of the transactions contemplated by this
Agreement shall be within the corporate powers of Newco and shall have been duly
authorized by all necessary corporate action on the part of Newco;

         (c) at the Merger Effective Time, the performance by Newco of this
Agreement and the consummation by Newco of the transactions contemplated by this
Agreement shall require no action by or in respect of, or filing with, any
Governmental Entity other than (i) compliance with any applicable requirements
of the Competition Act; (ii) compliance with any applicable requirements
relating to approval of the transactions contemplated by this Agreement by the
STB; (iii) compliance with any applicable requirements of the 1933 Act and the
1934 Act; (iv) compliance with any applicable United States "blue sky" or
Canadian provincial securities Laws; and (v) immaterial actions or filings
relating to ordinary operational matters;

         (d) at the Merger Effective Time, the performance by Newco of this
Agreement and the consummation by Newco of the transactions contemplated by this
Agreement will not (except in the case of clauses (ii), (iii) and (iv) of this
subsection (d), for any such matters that individually or in the aggregate would
not be reasonably likely to have a Material Adverse Effect on Newco) (i)
contravene or conflict with the certificate of incorporation or by-laws of
Newco, (ii) assuming compliance with the matters set forth in subsection (c)
above, contravene or conflict with or constitute a violation of any provisions
of any Law binding upon or applicable to Newco, (iii) constitute a default under
or give rise to any right of termination, cancellation or acceleration of any
right or obligation of Newco or any of its Subsidiaries or to a loss of any
benefit to which Newco or any of its Subsidiaries is entitled under any
agreement, contract or other instrument binding upon Newco or any of its
Subsidiaries or any license, franchise, permit or other similar authorization
held by Newco or any of its Subsidiaries or (iv) result in the creation of or
imposition of any material Lien on any asset of Newco or any Subsidiary of
Newco;

         (e) at the Merger Effective Time, Newco shall issue the Newco Common
Stock and the Newco Replacement Options in accordance with Section 2.3, and such
securities shall be duly authorized, validly issued and fully paid and
nonassessable;

         (f) from and after the Merger Effective Time, Newco shall, or shall
cause BNSF to, perform the obligations of BNSF under each agreement between BNSF
and any employee of BNSF providing for protections or benefits to such employee
in the event of a change of control, and Newco and CN together shall ensure that
the obligations of CN under each agreement



                                       39


<PAGE>



between CN and any employee of CN providing for protections or benefits to such
employee in the event comparable circumstances are satisfied; and

         (g) from the date hereof until the Arrangement Effective Time, Newco
shall not engage in any activities other than in connection with or as
contemplated by this Agreement.

         5.12 Implementation Committee. Immediately after the date of this
Agreement, BNSF and CN will establish a committee (the "Implementation
Committee") consisting of three representatives of BNSF and two representatives
of CN. The initial BNSF representatives shall be Robert D. Krebs, Thomas N. Hund
and Matthew K. Rose and the initial CN representatives shall be Paul M. Tellier
and E. Hunter Harrison. The successor to any representative on the
Implementation Committee shall be designated by the party that designated such
representative. Without in any way limiting their rights under Article VIII or
Article IX, BNSF and CN agree that the Implementation Committee shall be
responsible, on behalf of both parties, for directing the preparation and
presentation to the STB of all filings and other presentations in connection
with seeking any STB approval, exemption or other authorization necessary to
consummate the transactions contemplated by this Agreement, the prosecution of
such filings and other presentation and negotiation (with the STB or any third
party) of any matters in connection with seeking such approval. In addition to
the foregoing, to the extent permitted by applicable Law, the Implementation
Committee shall work actively to develop plans for the integration of the
operations of CN and BNSF after the Arrangement Effective Time. BNSF and CN
agree that the principal objectives of the Implementation Committee are to
ensure that the STB approval of the transactions contemplated by this Agreement
is obtained as expeditiously and on terms as favorable to Newco, BNSF, CN and
their respective Subsidiaries as is reasonably possible, and to develop plans
for the integration of the operations of BNSF and CN that will permit the most
expeditious and favorable integration of such operations as is reasonably
possible. The Implementation Committee shall act by consensus and not by
majority vote of its members. The composition of the Implementation Committee
reflects the nature of the issues to be addressed by the Implementation
Committee with respect to CN and BNSF, and the fact that the STB process will
relate to issues in the United States rather than to the relative influence of
CN and BNSF on the Implementation Committee.

         5.13 Interline Coordinations. As soon as practicable after the date of
this Agreement, BNSF and CN shall, to the extent consistent with applicable Law,
work in good faith to develop and implement a range of mutually beneficial
interline coordinations. Without limiting the generality of the foregoing, it is
currently contemplated that such interline coordinations will include, among
other things, to the extent consistent with applicable Law, matters relating to
information technology (intended to develop a common information technology
platform), procurement and marketing.

                                       40


<PAGE>



         5.14 Dividends. CN and BNSF shall coordinate the declaration, setting
of record dates and payment dates of dividends on CN and BNSF common stock so
that (i) holders of CN common stock do not receive dividends on both CN Common
Shares, on the one hand, and Newco Common Shares or CN Exchangeable Shares
received in the Arrangement, on the other hand, in respect of any calendar
quarter or fail to receive a dividend on either CN Common Shares, on the one
hand, or Newco Common Shares or CN Exchangeable Shares received in the
Arrangement, on the other hand, in respect of any calendar quarter and (ii)
holders of BNSF common stock do not receive dividends on both BNSF Common
Shares, on the one hand, and Newco Common Shares received in the Merger, on the
other hand, in respect of any calendar quarter or fail to receive a dividend on
either BNSF Common Shares, on the one hand, or Newco Common Shares received in
the Merger, on the other hand, in respect of any calendar quarter.

         5.15 Shareholder Rights Plans and Similar Matters. BNSF shall not
reduce or cause to be reduced the percentage threshold in the definition of
"Acquiring Person" set forth in the BNSF Shareholder Rights Plan or take any
other action that would impact the ability of CN to exercise the option granted
to CN under the BNSF Stock Option Agreement or CN's ability to own, vote and
exercise all rights of ownership of the BNSF Common Shares purchased by CN upon
exercise of the option granted to CN under the BNSF Stock Option Agreement. CN
shall not adopt or cause to be adopted a shareholder rights plan or similar
arrangement that would impact the ability of BNSF to exercise the option granted
to BNSF under the CN Stock Option Agreement or BNSF's ability to own, vote and

                                   ARTICLE VI

                                 COVENANTS OF CN

         6.1 Conduct of CN. From the date of this Agreement until the
Arrangement Effective Time, except as provided in Section 6.1 of the CN
Disclosure Letter, CN and CN's Subsidiaries shall conduct their business in the
ordinary course of business consistent with past practice and shall use their
reasonable best efforts to preserve intact their business organizations and
relationships with third parties; provided, however, that nothing in this
Section 6.1 shall be deemed to prevent CN and its Subsidiaries from taking any
action referred to in clauses (b)(ii), (c), (f) or (g) of this Section 6.1 where
the taking of such action is not consistent with the past practices of CN and
its Subsidiaries if, but only if, such action is a Customary Action.
Notwithstanding anything to the contrary in this Agreement, CN shall be
permitted to repurchase CN Common Shares from time to time prior to the Closing
in open market purchases, at the prevailing market price; provided, however,
that such repurchases shall not, in the aggregate, have the effect of (i)
decreasing the number of issued and outstanding CN Common Shares by more than
2.5% during any calendar quarter, as compared to the number of issued and
outstanding CN Common Shares at the beginning of such calendar quarter or (ii)
decreasing the



                                       41


<PAGE>



number of issued and outstanding CN Common Shares by more than 8.0% during any
calendar year, as compared to the number of issued and outstanding CN Common
Shares at the beginning of such calendar year. Without limiting the generality
of the foregoing, from the date of this Agreement until the Closing, without the
written consent of BNSF, which shall not be unreasonably withheld:

                    (a) Except for the Arrangement, CN shall not adopt or
         propose any change in its constitutive documents;

                    (b) Except for the Arrangement and the other transactions
         contemplated by this Agreement, CN shall not, and shall not permit any
         CN Subsidiary, to (i) adopt a plan of complete or partial liquidation,
         dissolution, merger, consolidation, restructuring, recapitalization or
         other reorganization or (ii) make any acquisition of any business or
         other assets, whether by means of merger, consolidation or otherwise,
         other than in the ordinary course of business consistent with past
         practices and other than acquisitions that are Customary Actions;
         provided, however, that any wholly owned subsidiary of CN may merge or
         consolidate with CN or any other wholly owned subsidiary of CN and any
         wholly owned subsidiary of CN that is not a Material Subsidiary may be
         liquidated or dissolved;

                    (c) CN shall not, and shall not permit any CN Subsidiary to,
         sell, lease, license or otherwise dispose of any material assets or
         property except (i) pursuant to existing contracts or commitments, (ii)
         in the ordinary course of business consistent with past practice and
         (iii) any such sale, lease, license or other disposition that is a
         Customary Action or that is to any wholly owned Subsidiary of CN;

                    (d) CN shall not, and shall not permit any of its
         Subsidiaries to, declare, set aside or pay any dividend or make any
         other distribution with respect to any shares of CN capital stock other
         than cash dividends on CN Common Shares not in excess of Canadian $0.70
         per share, per year;

                    (e) Except (i) as expressly permitted by Article II or
         Section 6.1(h), (ii) pursuant to existing contracts or commitments or
         (iii) pursuant to CN Options and other awards outstanding on the date
         of this Agreement, CN shall not, and shall not permit any of its
         Subsidiaries to, issue, deliver or sell, or authorize or propose the
         issuance, delivery or sale of, any CN Securities, any CN Voting Debt,
         any securities or ownership interests in any Material Subsidiary of CN
         or any securities convertible into or exchangeable for, or any rights,
         warrants or options to acquire, any CN Securities, CN Voting Debt or
         securities or ownership interests in any Material Subsidiary of CN;

                    (f) Except for (i) borrowings under existing credit
         facilities, replacements therefor and refinancings thereof, (ii)
         borrowings in the ordinary course of business consistent with past
         practice or (iii) borrowings that are Customary Actions, CN shall not,
         and shall not permit any of its Subsidiaries to, incur any indebtedness
         for borrowed money or guarantee any such indebtedness;

                    (g) Except for loans, advances, capital contributions or
         investments made in the ordinary course of business consistent with
         past practice and except for loans, advances, capital contributions or
         investments that are Customary Actions, CN shall not, and shall not
         permit any of its Subsidiaries to, make any loans, advances or capital
         contributions to, or investments in, any other Person (other than to CN
         or any Subsidiary of CN);

                    (h) (i) Except for any of the actions referred to in this
         clause (h)(i) that is taken in the ordinary course of business
         consistent in magnitude and character with past practice and with the
         terms of severance or termination arrangements in effect or pending on
         the date of this Agreement with respect to individuals with comparable
         positions or responsibilities, and except for any of such actions that,
         in the aggregate, are not material, CN shall not, and shall not permit
         any of its Subsidiaries to, grant any severance or termination pay to,
         or enter into any termination or severance arrangement with, any of its
         directors, executive officers or employees and (ii) except for any of
         the actions referred to in this clause (h)(ii) that is taken in the
         ordinary course of business consistent in magnitude and character with
         past practice, and except for any of such actions that in the aggregate
         are not material, CN shall not, and shall not permit any of its
         Subsidiaries to, establish, adopt, enter into, amend or take action to
         accelerate any rights or benefits under, or grant awards under, (A) any
         plan or arrangement providing for options, stock, performance awards or
         other forms of incentive or deferred compensation or (B) any collective
         bargaining, bonus, profit sharing, thrift, compensation, restricted
         stock, pension, retirement, deferred compensation, employment,
         termination, severance or other plan, agreement, trust, fund, policy or
         arrangement for the benefit of any of its directors, executive officers
         or employees. Notwithstanding anything to the contrary in this
         Agreement, (i) CN may offer any of its directors, officers or employees
         retention and incentive arrangements comparable to those that BNSF has
         made available to its directors, officers and employees prior to the
         date of this Agreement or could offer to such directors, officers and
         employees under the terms of Section 7.1(h) and (ii) CN may take such
         action as it deems appropriate to compensate current or future holders
         of CN Options for any adverse Tax consequences resulting directly or
         indirectly from the Arrangement. For purposes of this Section 6.1(h)
         only, "material" shall mean material in relation to the overall
         compensation costs of CN and its Subsidiaries;



                                       43


<PAGE>



                    (i) CN shall not, and shall not permit any of its
         Subsidiaries to, make any cash capital expenditures in any calendar
         year in an aggregate amount in excess of $825 million;

                    (j) Neither CN's board of directors nor any committee
         thereof shall adopt any resolution or take any other action to
         determine or declare that any of the transactions contemplated by this
         Agreement will constitute a change in control for purposes of any CN
         Employee Plan; and

                    (k) CN shall not, and shall not permit any of its
         Subsidiaries to, agree or commit to do any of the actions prohibited by
         Sections 6.1(a) through 6.1(j).

         6.2 Tax Matters. From the date of this Agreement until the Arrangement
Effective Time, except as would not be reasonably likely to have a Material
Adverse Effect on CN, CN shall, and shall cause its Subsidiaries to, (i) file
all tax returns, statements, reports and forms (collectively, the "CN
Post-Signing Returns") required to be filed with any taxing authority in
accordance with all applicable Laws; (ii) timely withhold or pay all Taxes
required to be withheld or shown as due and payable on the CN Post-Signing
Returns that are so filed and, as of the time of filing, the CN Post-Signing
Returns shall be true, complete and correct; (iii) make provision for all Taxes
payable by CN and its Subsidiaries for which no CN Post-Signing Return is due
prior to the Arrangement Effective Time; and (iv) promptly notify BNSF of any
action, suit, proceeding, investigation, audit or claim pending against or with
respect to CN or any of its Subsidiaries in respect of any Tax where a
determination or decision against CN is more probable than not.

         6.3 No Solicitations; Other Offers. (a) CN agrees that neither it nor
any of its Subsidiaries nor any of the officers and directors of it or its
Subsidiaries shall, and that it shall direct and use its best efforts to cause
its and its Subsidiaries' employees, agents and representatives (including any
investment banker, attorney or accountant retained by it or any of its
Subsidiaries) (CN, its Subsidiaries and their officers, directors, employees,
agents and representatives being referred to as the "CN Representatives") not
to, directly or indirectly, initiate, solicit, encourage or otherwise facilitate
any inquiries or the making of any proposal or offer with respect to an
Alternative Proposal. CN further agrees that neither it nor any of its
Subsidiaries nor any of the officers and directors of it or any of its
Subsidiaries shall, and that it shall direct and use its best efforts to cause
the CN Representatives not to, directly or indirectly, have any discussion with
or provide any confidential information or data relating to or in contemplation
of an Alternative Proposal or engage in any negotiations or discussions
concerning an Alternative Proposal, or otherwise facilitate any effort or
attempt to make or implement an Alternative Proposal; provided, however, that
nothing contained in this Agreement shall prevent either CN or its directors
from: (A) complying with Rule 14d-9 and Rule 14e-2 promulgated under the 1934
Act with regard to an Alternative Proposal or complying with the



                                       44


<PAGE>



requirements of the CBCA and applicable Canadian securities Laws in relation to
the preparation and dissemination of directors' circulars in response to
take-over bids and the calling and holding of requisitioned stockholders
meetings; (B) prior to the taking of the vote to be taken at the CN Stockholder
Meeting, engaging in any discussions or negotiations with, or providing any
information to, any Person in response to an unsolicited bona fide written
Alternative Proposal; or (C) prior to the taking of the vote to be taken at the
CN Stockholder Meeting, subject to the obligation of CN pursuant to Section
2.1(b) to duly convene the CN Stockholder Meeting at which a vote of the
stockholders of CN shall be taken regarding the approval and adoption of the
Arrangement Resolutions, recommending such an unsolicited bona fide written
Alternative Proposal to the stockholders of CN if, and only to the extent that,
with respect to the actions referred to in clauses (B) or (C), (i) CN has
complied with the terms of this Section 6.3, (ii) the board of directors of CN
concludes in good faith (after consultation with its outside legal counsel and
its financial advisors) that such Alternative Proposal is reasonably capable of
being completed, taking into account all legal, financial, regulatory and other
aspects of the proposal and the Person making the proposal, and would, if
consummated, result in a transaction more favorable to CN's stockholders from a
financial point of view than the transactions contemplated by this Agreement,
(iii) the board of directors of CN determines in good faith after consultation
with outside legal counsel that the failure to take such action would result in
the reasonable likelihood that the board of directors would breach its fiduciary
duties under applicable Law, and (iv) prior to entering into negotiations or
discussions with, or providing any information or data to, any Person in
connection with an Alternative Proposal by any such Person, the board of
directors of CN shall receive from such Person an executed confidentiality
agreement on terms substantially similar to those contained in the
Confidentiality Agreement; provided, however, that such confidentiality
agreement shall contain terms that allow CN to comply with its obligations under
this Section 6.3.

         (b) CN agrees that it will immediately cease and cause to be terminated
any existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Alternative Proposal. CN agrees that it will take
the necessary steps to promptly inform each CN Representative of the obligations
undertaken in Section 6.3(a). CN agrees that it will notify BNSF promptly, but
in any event within twenty-four (24) hours, if any such inquiries, proposals or
offers are received by, any such information is requested from, or any such
discussions or negotiations are sought to be initiated or continued with, any CN
Representative indicating, in connection with such notice, the name of such
Person making such inquiry, proposal, offer or request and the substance of any
such inquiries, proposals or offers. CN thereafter shall keep BNSF informed, on
a timely basis, of the status and terms of any such inquiries, proposals or
offers and the status of any such discussions or negotiations. Without limiting
the generality of the foregoing, the notice delivered by CN commencing the CN
Five Business Day Window shall set forth all material terms of the Alternative
Proposal or other matter forming the basis for the withdrawal, modification or
change by CN's board of directors of its recommendation that the CN stockholders
approve and adopt the Arrangement Resolution and such notice shall be



                                       45


<PAGE>



updated in writing on a current basis in the event that any such material terms
are modified or changed. Without limiting BNSF's right to make proposals in
general, BNSF shall be permitted to make one or more proposals to CN during the
CN Five Business Day Window and such proposals shall be considered by CN. CN
also agrees that it will promptly request each Person that has heretofore
executed a confidentiality agreement in connection with its consideration of any
Alternative Proposal to return all confidential information heretofore furnished
to such Person by or on behalf of CN or any of its Subsidiaries.

action is not consistent with the past practices of BNSF and its Subsidiaries
if, but only if, such action is a Customary Action. Notwithstanding anything to

at the beginning of such calendar quarter or (ii) decreasing the number of
issued and outstanding BNSF Common Shares by more than 8.0% during any calendar
year, as compared to the number of issued and outstanding BNSF Common Shares at
the beginning of such calendar year. Without limiting the generality of the

         practice and with the terms of severance or termination arrangements in
         effect or pending on the date of this Agreement with respect to

stockholders of BNSF shall be taken regarding the approval and adoption of this
Agreement and the transactions contemplated by this Agreement, recommending such
an unsolicited bona fide written Alternative Proposal to the stockholders of
BNSF if, and only to the extent that, with respect to the actions referred to in
clauses (B) or (C), (i) BNSF has complied with the terms of this Section 7.3,
(ii) the board of directors of BNSF concludes in good faith (after consultation
with its outside legal counsel and its financial advisors) that such Alternative
Proposal is reasonably capable of being completed, taking into account all
legal, financial, regulatory and other aspects of the proposal and the Person
making the proposal, and would, if consummated, result in a transaction more
favorable to BNSF's stockholders from a financial point of view than the
transactions contemplated by this Agreement, (iii) the board of directors of
BNSF determines in good faith after consultation with outside legal counsel that
the failure to take such action would result in the reasonable likelihood that
the board of directors would breach its fiduciary

duties to BNSF or its stockholders under applicable Law and (iv) prior to
entering into negotiations or discussions with, or providing any information or
data to, any Person in connection with an Alternative Proposal by any such
Person, the board of directors of BNSF shall receive from such Person an
executed confidentiality agreement on terms substantially similar to those
contained in the Confidentiality Agreement; provided, however, that such
confidentiality agreement shall contain terms that allow BNSF to comply with its
obligations under this Section 7.3.

         (b) BNSF agrees that it will immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any Alternative Proposal. BNSF agrees that
it will take the necessary steps to promptly inform each BNSF Representative of
the obligations undertaken in Section 7.3(a). BNSF agrees that it will notify CN
promptly, but in any event within twenty-four (24) hours, if any such inquiries,
proposals or offers are received by, any such information is requested from, or
any such discussions or negotiations are sought to be initiated or continued
with, any BNSF Representative indicating, in connection with such notice, the
name of such Person making such inquiry, proposal, offer or request and the
substance of any such inquiries, proposals or offers. BNSF thereafter shall keep
CN informed, on a timely basis, of the status and terms of any such inquires,
proposals or offers and the status of any such discussions or negotiations.
Without limiting the generality of the foregoing, the notice delivered by BNSF
commencing the BNSF Five Business Day Window shall set forth all material terms
of the Alternative Proposal or other matter forming the basis for the
withdrawal, modification or change by BNSF's board of directors of its
recommendation that the BNSF stockholders approve and adopt this Agreement and
such notice shall be updated in writing on a current basis in the event that any
such material terms are modified or changed. Without limiting CN's right to make
proposals in general, CN shall be permitted to make one or more proposals to
BNSF during the BNSF Five Business Day Window and such proposals shall be
considered by BNSF. BNSF also agrees that it will promptly request each Person
that has heretofore executed a confidentiality agreement in connection with its
consideration of any Alternative Proposal to return all confidential information
heretofore furnished to such Person by or on behalf of BNSF or any of its
Subsidiaries.

         7.4 Takeover Statutes; Rights Plan. BNSF shall take all actions
necessary to ensure that the representations and warranties set forth in Section
4.16 remain true and correct at all times.

<PAGE>



                    (i) CN shall have performed in all material respects all of

         representations and warranties speak as of an earlier time, in which
         event such representations and warranties shall be true and correct as
         of such earlier time), except where the failure of such representations
         and warranties (other than those in Section 3.5) to be true and
         correct, individually or in the aggregate, would not be reasonably
         likely to have a Material Adverse Effect on CN (it being understood
         that the representations and warranties of CN made in Section 3.5 must
         be accurate in all significant respects when made and, except as
         contemplated by this Agreement, at and as of the Merger Effective Time

         result of changes in the conditions, including economic and political
         developments, applicable to the railroad industry in general or any
         changes in the economy or securities markets in general).

         been accurate both when made and at and as of the Arrangement Effective
         Time as if made at and as of that time (except to the extent such
         representations and warranties speak as of an earlier time, in which
         event such representations and warranties shall be true and correct as
         of such earlier time), except where the failure of such representations
         and warranties (other than those in Sections 4.5 and 4.16) to be true
         and correct, individually or in the aggregate, would not be reasonably
         likely to have a Material Adverse Effect on BNSF (it being understood
         that the representations and warranties of BNSF made in Section 4.5 and
         4.16 must be accurate in all significant respects when made and, except
         as contemplated by this Agreement, at and as of the Arrangement
         Effective Time as if made at and as of that time); and

                    (iii) since the date of this Agreement, there shall not have
         been any event, occurrence, development or state of circumstances that,
         individually or in the aggregate, has had or could reasonably be
         expected to have a Material Adverse Effect on BNSF (other than as a
         result of changes in the conditions, including economic and political
         developments, applicable to the railroad industry in general or any
         changes in the economy or securities markets in general).

                                   ARTICLE IX

                                   TERMINATION

         9.1 Termination. This Agreement may be terminated and the transactions
contemplated by this Agreement may be abandoned at any time prior to the Closing
(notwithstanding any approval of this Agreement by the stockholders of BNSF or
CN):

                    (i)  by mutual written consent of BNSF and CN;

                    (ii) by either BNSF or CN, if the Closing has not occurred
         by December 31, 2002 (the "Outside Date");

                    (iii) by either BNSF or CN, if (a) any judgment, injunction,
         order or decree enjoining BNSF or CN from consummating the Merger or
         Arrangement is entered and such judgment, injunction, order or decree
         shall become final and nonappealable or (b) the Court elects not to
         issue the Final Order and the Court's decision on the matter has been
         fully appealed (and not reversed) or has become final and
         nonappealable;

                    (iv) by either BNSF or CN, if the approvals of the
         stockholders of BNSF or CN contemplated by this Agreement shall not
         have been obtained by reason of the failure to obtain the required vote
         at a duly held meeting of stockholders or of any adjournment thereof;

                    (v) by BNSF, if the board of directors of CN shall have
         withdrawn, adversely modified or changed its approval or recommendation
         of this Agreement, the transactions contemplated by this Agreement or
         the Arrangement Resolution;

                    (vi) by CN, if the board of directors of BNSF shall have
         withdrawn, adversely modified or changed its approval or recommendation
         of this Agreement or the transactions contemplated by this Agreement;

                    (vii) by BNSF, upon a breach of any representation,
         warranty, covenant or agreement of CN, or if any representation or
         warranty of CN shall become untrue, in either case such that the
         conditions set forth in Section 8.2 would be incapable of being



                                       54


<PAGE>



         satisfied by the Outside Date (or as otherwise extended), provided that
         a wilful breach shall be deemed to cause such conditions to be
         incapable of being satisfied by such date;

                    (viii) by CN, upon a breach of any representation, warranty,
         covenant or agreement of BNSF, or if any representation or warranty of
         BNSF shall become untrue, in either case such that the conditions set
         forth in Section 8.3 would be incapable of being satisfied by the
         Outside Date (or as otherwise extended), provided that a wilful breach
         shall be deemed to cause such conditions to be incapable of being
         satisfied by such date; or

                    (ix) by either BNSF or CN at any time prior to December 31,
         2002, if the STB shall have issued a decision (which decision shall not
         have been stayed or enjoined) that (A) constitutes a final order
         approving, exempting or otherwise authorizing consummation of the
         transactions contemplated by this Agreement (or subsequently presented
         to the STB by agreement of BNSF and CN), including the Arrangement and
         the Merger, as may require such authorization and (B)(1) changes the
         Exchange Ratio or (2) imposes on BNSF, Newco, CN or any of their
         respective Subsidiaries any other terms or conditions (including labor
         protective provisions, but excluding conditions heretofore imposed by
         the United States Interstate Commerce Commission in New York Dock
         Railway-Control-Brooklyn Eastern District, 360 I.C.C. 60 (1979)) that
         would significantly and adversely affect the economic benefits of the
         transactions contemplated by this Agreement to BNSF, CN and their
         stockholders, taken as a whole (such decision, an "Adverse STB
         Decision").

         9.2 Effect of Termination. If this Agreement is terminated pursuant to
Section 9.1, this Agreement shall become void and of no effect with no liability
on the part of any party to this Agreement, except that (i) the agreements
contained in Sections 3.14, 4.14, 4.16, 5.15, 7.4, 10.4, 10.5, 10.6, 10.7, 10.8,
10.10, 10.11, and 10.12 shall survive such termination and (ii) no such
termination shall relieve any party of any liability or damages resulting from
any breach by that party of this Agreement.

                                    ARTICLE X

                            MISCELLANEOUS AND GENERAL

         10.1 Modification, Amendment and Assignment. Subject to the provisions
of applicable Law, at any time prior to the Closing, the parties to this
Agreement may modify or amend this Agreement, by written agreement executed and

this Agreement.



                                       55


<PAGE>



         10.2 Waiver of Conditions. (a) Any party to this Agreement may (i)
extend the time for the performance of any of the obligations or other acts of
the other parties to this Agreement, (ii) waive any inaccuracies in the
representations and warranties of the other parties to this Agreement contained
in this Agreement or in any document delivered by the other pursuant to this
Agreement or (iii) waive compliance with any of the agreements, or satisfaction
of any of the conditions, contained in this Agreement by the other parties to
this Agreement. Any agreement on the part of a party to this Agreement to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed by such party.

         (b) No failure or delay by any party in exercising any right, power or
privilege under this Agreement shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. Except as
otherwise provided in this Agreement, the rights and remedies provided in this
Agreement shall be cumulative and not exclusive of any rights or remedies
provided by Law.

         10.3 Counterparts. This Agreement may be executed in any number of
counterparts, each such counterpart being deemed to be an original instrument,
and all such counterparts shall together constitute the same agreement.

         10.4 Expenses; Certain Payments. (a) Except as otherwise provided in
this Section 10.4 or agreed in writing by the parties, each party shall bear its
own expenses (including the fees and expenses of any attorneys, accountants,
investment bankers, brokers, finders or other intermediaries or other Persons
engaged by it) incurred in connection with this Agreement and the transactions
contemplated by this Agreement. CN and BNSF shall share equally all expenses
incurred by either party in connection with any action approved or authorized by
the Implementation Committee.

         (b) BNSF shall pay CN a fee equal to $450 million (the "BNSF
Termination Fee"), which amount shall be payable by wire transfer of same day
funds, in the event that (i) an Alternative Proposal shall have been made to
BNSF or shall have been made directly to BNSF's stockholders generally or any
Person shall have publicly announced an intention (whether or not conditional)
to make an Alternative Proposal with respect to BNSF and thereafter (A) BNSF's
stockholders do not adopt this Agreement at the BNSF Stockholder Meeting and (B)
this Agreement is terminated by either CN or BNSF; or (ii) this Agreement is
terminated by CN pursuant to Section 9.1(vi) or (viii) (but, with respect to
Section 9.1(viii), solely with respect to a breach of Section 7.3). Such payment
shall be due and payable no later than the business day after the date that
notice of termination of this Agreement is first given. BNSF acknowledges that
the agreements contained in this Section 10.4(b) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
CN would not enter into this Agreement. Accordingly, if BNSF fails to pay when
due the amount due pursuant to this Section 10.4(b) and, in order to obtain such
payment, CN commences a suit which results in a



                                       56


<PAGE>



judgment against BNSF for the fee set forth in this Section 10.4(b), BNSF shall
pay to CN its costs and expenses (including attorneys' fees) in connection with
such suit, together with interest on the amount of the fee at the prime rate of
Citibank N.A. in effect on the date such payment was required to be made.

         (c) CN shall pay BNSF a fee equal to $200 million (the "CN Termination
Fee"), which amount shall be payable by wire transfer of same day funds, in the
event that (i) an Alternative Proposal shall have been made to CN or shall have
been made directly to CN's stockholders generally or any Person shall have
publicly announced an intention (whether or not conditional) to make an
Alternative Proposal with respect to CN and thereafter (A) CN's stockholders do
not adopt the Arrangement Resolution at the CN Stockholder Meeting and (B) this
Agreement is terminated by either BNSF or CN; or (ii) this Agreement is
terminated by BNSF pursuant to Section 9.1(v) or (vii) (but, with respect to
9.1(vii), solely with respect to a breach of Section 6.3). Such payment shall be
due and payable no later than the business day after the date that notice of
termination of this Agreement is first given. CN acknowledges that the
agreements contained in this Section 10.4(c) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
BNSF would not enter into this Agreement. Accordingly, if CN fails to pay
promptly the amount due pursuant to this Section 10(c), and, in order to obtain
such payment, BNSF commences a suit which results in a judgment against CN for
the fee set forth in this Section 10.4(c), CN shall pay to BNSF its costs and
expenses (including attorneys' fees) in connection with such suit, together with
interest on the amount of the fee at the prime rate of Citibank N.A. in effect
on the date such payment was required to be made.

         (d) BNSF shall pay CN a fee equal to $300 million (the "BNSF STB
Termination Fee"), which amount shall be payable by wire transfer of same day
funds, in the event that (i) BNSF sends CN a written notice (the "BNSF STB
Notice") stating either that BNSF intends to terminate this Agreement pursuant
to Section 9.1(ix) or does not intend to consummate the transactions
contemplated by this Agreement in reliance on Section 8.1(iv); (ii) within five
business days after the date that CN receives BNSF's notice referred to in
clause (i) of this sentence, CN sends BNSF a written notice that,
notwithstanding the alleged Adverse STB Decision, CN is willing to consummate
the transactions contemplated by this Agreement; (iii) within three business
days after receiving the notice referred to in clause (ii) of this sentence,
BNSF does not send CN a written notice that, notwithstanding the alleged Adverse
STB Decision, BNSF is willing to consummate the transactions contemplated by
this Agreement and is revoking the BNSF STB Notice ; and (iv) the conditions to
Closing for CN and BNSF other than the condition in Section 8.1(iv) (and any
other condition to Closing to the extent relating to any matter referred to in
Section 8.1(iv)) have been or promptly could be satisfied or, if appropriate,
waived. If CN sends the notice referred to in clause (ii) above, CN shall be
deemed to have waived its right to terminate this Agreement pursuant to Section
9.1(ix) (or pursuant to any other provision of this Agreement for reasons
relating to any matter referred to in Section



                                       57


<PAGE>



9.1(ix)) and to have taken the position that the condition in Section 8.1(iv)
has been satisfied and that all of the other conditions to Closing for CN have
been or promptly could be satisfied or waived. Upon the revocation referred to
in clause (iii) above, BNSF shall be deemed to have waived its right to
terminate this Agreement pursuant to Section 9.1(ix) (or pursuant to any other
provision of this Agreement for reasons relating to any matter referred to in
Section 9.1(ix)) and to have taken the position that the condition in Section
8.1(iv) has been satisfied and that all of the other conditions to closing for
BNSF have been or promptly could be satisfied or waived. If BNSF fails to
deliver the written notice contemplated by clause (i) of the first sentence in
this Section 10.4(d) within five business days of the issuance by the STB of a
decision (which decision has not been stayed or enjoined) constituting a final
order approving, exempting or otherwise authorizing the consummation of the
transactions contemplated by this Agreement, BNSF shall be deemed to have waived
the condition to Closing set forth in Section 8.1(iv) (as well as any other
condition to Closing for reasons relating to any matter referred to in Section
8.1(iv)) as well as its right to terminate this Agreement pursuant to Section
9.1(ix) (or pursuant to any other provision of this Agreement for reasons
relating to any matter referred to in Section 9.1(ix)). Assuming that clauses
(i), (ii), (iii) and (iv) above have been satisfied, the BNSF STB Termination
Fee shall be due and payable no later than the second business day after the
notice referred to in clause (iii) above has not been and can no longer be
given. If CN does not send the notice referred to in clause (ii) above within
five business days after the date on which CN receives BNSF's notice delivered
pursuant to clause (i) of the first sentence of this Section 10.4(d), CN shall
be deemed to have waived its right to send the notice referred to in clause (ii)
above, BNSF shall not owe the BNSF STB Termination Fee and the BNSF STB Notice
shall be deemed final. The BNSF STB Notice shall also be deemed to be final if
the BNSF STB Termination Fee becomes due and payable. This Agreement shall
terminate at such time the BNSF STB Notice shall be deemed final in accordance
with either of the two immediately preceding sentences. BNSF acknowledges that
the agreements contained in this Section 10.4(d) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
CN would not enter into this Agreement. Accordingly, if BNSF fails to pay the
amount when due pursuant to this Section 10.4(d) and, in order to obtain such
payment, CN commences a suit which results in a judgment against BNSF for the
fee set forth in this Section 10.4(d), BNSF shall pay to CN its costs and
expenses (including attorneys' fees) in connection with such suit, together with
interest on the amount of the fee at the prime rate of Citibank, N.A. in effect
on the date such payment was required to be made. Nothing in this Section
10.4(d) shall prevent CN from asserting that no Adverse STB Decision has been
issued and that the condition to Closing in Section 8.1(iv) has been satisfied,
in either case, despite BNSF's claim to the contrary and that no termination
right arose under Section 9.1(ix); provided, however, that CN shall be deemed to
have waived the right to make such an assertion if it sends the notice referred
to in clause (ii) above. BNSF may not terminate this Agreement pursuant to
Section 9.1(ix) or elect not to consummate the transactions contemplated by this
Agreement on the basis of the condition set forth in Section 8.1(iv) unless BNSF
has complied with the provisions of this Section 10.4(d).

         (e) CN shall pay BNSF a fee equal to $150 million (the "CN STB
Termination Fee"), which amount shall be payable by wire transfer of same day
funds, in the event that (i) CN sends BNSF a written notice (the "CN STB
Notice") stating either that CN intends to terminate this Agreement pursuant to
Section 9.1(ix) or does not intend to consummate the transactions contemplated
by this Agreement in reliance on Section 8.1(iv); (ii) within five business days
after the date that BNSF receives CN's notice referred to in clause (i) of this
sentence, BNSF sends CN a written notice that, notwithstanding the alleged
Adverse STB Decision, BNSF is willing to consummate the transactions
contemplated by this Agreement; (iii) within three business days after receiving
the notice referred to in clause (ii) of this sentence, CN does not send BNSF a
written notice that, notwithstanding the alleged Adverse STB Decision, CN is
willing to consummate the transactions contemplated by this Agreement and is
revoking the CN STB Notice; and (iv) the conditions to Closing for BNSF and CN
other than the condition in Section 8.1(iv) (and any other condition to Closing
to the extent relating to any matter referred to in Section 8.1(iv)) have been
or promptly could be satisfied or, if appropriate, waived. If BNSF sends the
notice referred to in clause (ii) above, BNSF shall be deemed to have waived its
right to terminate this Agreement pursuant to Section 9.1(ix) (or pursuant to
any other provision of this Agreement for reasons relating to any matter
referred to in Section 9.1 (ix)) and to have taken the position that the
condition in Section 8.1(iv) has been satisfied and that all of the other
conditions to Closing for BNSF have been or promptly could be satisfied or
waived. Upon the revocation referred to in clause (iii) above, CN shall be
deemed to have waived its right to terminate this Agreement pursuant to Section
9.1(ix) (or pursuant to any other provision of this Agreement for reasons
relating to any matter referred to in Section 9.1 (ix)) and to have taken the
position that the condition in Section 8.1(iv) has been satisfied and that all
of the other conditions to closing for CN have been or promptly could be
satisfied or waived. If CN fails to deliver the written notice contemplated by
clause (i) of the first sentence in this Section 10.4(e) within five business
days of the issuance by the STB of a decision (which decision has not been
stayed or enjoined) constituting a final order approving, exempting or otherwise
authorizing the consummation of the transactions contemplated by this Agreement,
CN shall be deemed to have waived the condition to Closing set forth in Section
8.1(iv) (as well as any other condition to Closing for reasons relating to any
matter referred to in Section 8.1(iv)) as well as its right to terminate this
Agreement pursuant to Section 9.1(ix) (or pursuant to any other provision of
this Agreement for reasons relating to any matter referred to in Section
9.1(ix)). Assuming that clauses (i), (ii), (iii) and (iv) above have been
satisfied, the CN STB Termination Fee shall be due and payable no later than the
second business day after the notice referred to in clause (iii) above has not
been and can no longer be given. If BNSF does not send the notice referred to in
clause (ii) above within five business days after the date on which BNSF
receives CN's notice delivered pursuant to clause (i) of the first sentence of
this Section 10.4(e), BNSF shall be deemed to have waived its right to send the
notice referred to in clause (ii) above, CN shall not owe the CN STB Termination
Fee and the CN STB Notice shall be deemed final. The CN Notice shall also be
deemed to be final if the CN STB Termination Fee becomes due and payable. This
Agreement shall terminate at such time the CN Notice shall be deemed final in
accordance with either of the

two immediately preceding sentences. CN acknowledges that the agreements
contained in this Section 10.4(e) are an integral part of the transactions
contemplated by this Agreement and that, without these agreements, BNSF would
not enter into this Agreement. Accordingly, if CN fails to pay the amount when
due pursuant to this Section 10.4(e) and, in order to obtain such payment, BNSF
commences a suit which results in a judgment against CN for the fee set forth in
this Section 10.4(e), CN shall pay to BNSF its costs and expenses (including
attorneys' fees) in connection with such suit, together with interest on the
amount of the fee at the prime rate of Citibank, N.A. in effect on the date such
payment was required to be made. Nothing in this Section 10.4(e) shall prevent
BNSF from asserting that no Adverse STB Decision has been issued and that the
condition to Closing in Section 8.1(iv) has been satisfied, in either case,
despite CN's claim to the contrary and that no termination right arose under
Section 9.1(ix); provided, however, that BNSF shall be deemed to have waived the
right to make such an assertion if it sends the notice referred to in clause
(ii) above. CN may not terminate this Agreement pursuant to Section 9.1(ix) or
elect not to consummate the transactions contemplated by this Agreement on the
basis of the condition set forth in Section 8.1(iv) unless CN has complied with
the provisions of this Section 10.4(e).

         10.5 Governing Law and Venue; Waiver of Jury Trial. (a) This Agreement
shall be deemed to be made in and in all respects shall be interpreted,
construed and governed by and in accordance with the Laws of the State of New
York without regard to the conflict of law principles thereof; provided,
however, that matters relating to CN's corporate affairs and the Arrangement
shall be governed by the Laws of Canada without regard to conflict of laws
principles thereof and matters relating to BNSF's corporate affairs and the
Merger shall be governed by the Laws of Delaware without regard to conflict of
laws principles thereof. The parties hereby irrevocably and unconditionally
consent to submit to the exclusive jurisdiction of both the courts of the State
of Delaware and of the United States of America located in Wilmington, Delaware

this Agreement and the transactions contemplated by this Agreement, waive any
objection to the laying of venue of any such litigation in the Delaware Courts
or the Quebec Court and agree not to plead or claim in any Delaware Court or the
Quebec Court that such litigation brought therein has been brought in an
inconvenient forum; provided, however, that the parties agree that any
proceedings in the Quebec Court arising out of or relating to this Agreement and
the transactions contemplated by this Agreement shall be conducted in English
and all written documents relating to any such proceedings shall be written in
English.

         (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION

DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH SUCH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH SUCH PARTY HAS BEEN INDUCED
TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND

         10.7 Entire Agreement. This Agreement (including any exhibits to this
Agreement and the ancillary agreements contemplated by this Agreement), the
Confidentiality Agreement, the BNSF Disclosure Letter and the CN Disclosure
Letter constitute the entire agreement, and supersede all other prior
agreements, understandings, representations and warranties both written and
oral, among the parties with respect to the subject matter of this Agreement.
EACH PARTY TO THIS AGREEMENT AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND
WARRANTIES CONTAINED IN THIS AGREEMENT, NEITHER CN NOR BNSF MAKES ANY
REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER
REPRESENTATIONS OR WARRANTIES MADE BY ITSELF OR ANY OF ITS OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, FINANCIAL AND LEGAL ADVISORS OR OTHER REPRESENTATIVES, WITH
RESPECT TO THE EXECUTION AND DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO
THE OTHER OR THE OTHER'S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER
INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

         10.8 No Third Party Beneficiaries. This Agreement is not intended to
confer upon any Person other than the parties to this Agreement any rights or
remedies under this Agreement.

         10.9 Severability. The provisions of this Agreement and any other
agreement contemplated by this Agreement shall be deemed severable and the
invalidity or unenforceability of any provision of this Agreement or any other
agreement contemplated by this Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement or any



                                       63


<PAGE>



provisions of such other agreements. Without limiting the generality of the
foregoing, the invalidity or unenforceability of any provision of any such other
agreement shall not affect the validity or enforceability of any provision of
this Agreement. If any provision of this Agreement or any other agreement
contemplated by this Agreement or the application thereof to any Person or any
circumstance, is invalid or unenforceable, (i) a suitable and equitable
provision shall be substituted therefor in order to carry out, so far as may be
valid and enforceable, the intent and purpose of such invalid or unenforceable
provision and (ii) the remainder of this Agreement or any provisions of such
other agreements and the application of such provision to other Persons or
circumstances shall not be affected by such invalidity or unenforceability, nor
shall such invalidity or unenforceability affect the validity or enforceability
of such provision, or the application thereof, in any other jurisdiction.

         10.10 Interpretation. The table of contents and headings in this
Agreement are for convenience of reference only, do not constitute part of this
Agreement and shall not be deemed to limit or otherwise affect any of the
provisions of this Agreement.

         10.11 Fair Construction. This Agreement shall be deemed to be the joint
work product of the parties without regard to the identity of the draftsperson,
and any rule of construction that a document shall be interpreted or construed
against the drafting party shall not be applicable.

         10.12 Limitation on Liability for Misrepresentations. Neither BNSF nor
CN shall have any liability for any breach of a representation or warranty
contained in this Agreement in respect of which the other party has notified
BNSF or CN, as the case may be, in writing that it has performed satisfactory
due diligence (a "Notified Matter"). Neither BNSF nor CN shall be permitted to
assert that any condition to such party's obligation to consummate the
transactions contemplated by this Agreement has not been satisfied as a result
of any Notified Matter.

         10.13 Survival. The representations and warranties and agreements
contained in this Agreement and in any certificate or other writing delivered
pursuant to this Agreement shall terminate at the Merger Effective Time, except
for the agreements contained in Sections 5.11(f), 10.4(a), 10.5, 10.6, 10.7,
10.8, 10.10, 10.11 and 10.13; provided, however, that nothing in this Agreement

ITEM 2A.
                                    Exhibit A

                                     FORM OF
                            CN STOCK OPTION AGREEMENT

         This STOCK OPTION AGREEMENT, dated as of December 18, 1999 (this
"Agreement"), is between CANADIAN NATIONAL RAILWAY COMPANY, a Canadian
corporation ("Issuer"), and BURLINGTON NORTHERN SANTA FE CORPORATION, a Delaware
corporation ("Grantee").

                                    RECITALS

         A. The Combination Agreement. Prior to the entry into this Agreement
and prior to the grant of the Option (as defined in Section 1(a)), Issuer,
Grantee, NORTH AMERICAN RAILWAYS, INC., a Delaware corporation owned 50% by
Issuer and 50% by Grantee ("Newco"), and Western Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Newco ("Merger Sub"), have entered
into a Combination Agreement, dated as of the date of this Agreement (the
"Combination Agreement"), pursuant to which Grantee and Issuer have agreed to
effect certain transactions upon the terms and subject to the conditions set
forth in the Combination Agreement.

         B. The Stock Option Agreement. As an inducement and condition to
Grantee's willingness to enter into the Combination Agreement, and in
consideration thereof, the board of directors of Issuer has approved the grant
to Grantee of the Option pursuant to this Agreement and the acquisition of
Common Stock (as defined below) by Grantee pursuant to this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth in this Agreement and in the Combination
Agreement, the parties agree as follows:

         1. The Option. (a) Issuer hereby grants to Grantee an irrevocable
option (the "Option") to purchase, subject to the terms and conditions of this
Agreement, up to 28,895,812 fully paid and nonassessable common shares in the
capital of Issuer ("Common Stock"), of Issuer at a price per share in cash equal
to the average of the closing price of Issuer's Common Stock on the New York
Stock Exchange (as reported in The Wall Street Journal, New York City edition)
on the five trading days ending on the last trading day preceding the Notice
Date (as defined below) (the "Option Price"); provided, however, that in no
event shall the number of shares for which the Option is exercisable exceed
12.5% of the shares of Common Stock issued and outstanding at the time of
exercise (giving effect to the shares of Common Stock issued or issuable under
the Option) (the "Maximum Applicable Percentage"). The number of shares of
Common Stock purchasable upon exercise of the Option are subject to adjustment
as set forth in this Agreement.
<PAGE>

         (b) In the event that any additional shares of Common Stock are issued
or otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement), the aggregate number of shares of Common Stock
purchasable upon exercise of the Option (inclusive of shares, if any, previously
purchased upon exercise of the Option) shall automatically be increased (without
any further action on the part of Issuer or Grantee being necessary) so that,
after such issuance, it equals the Maximum Applicable Percentage. No such
increase shall affect the Option Price.

         2. Exercise; Closing. (a) Manner of Exercise; Termination. Grantee or
any other person that shall become a holder of all or part of the Option in
accordance with the terms of this Agreement (each such person being sometimes
referred to in this Agreement as the "Holder") may exercise the Option, in whole
or in part, by delivering a written notice thereof as provided in Section 2(d)
within 18 months following the occurrence of a Triggering Event (as defined in
Section 2(b)) unless prior to such Triggering Event either the Merger Effective
Time or the Arrangement Effective Time (as such terms are defined in the
Combination Agreement) shall have occurred or the Option shall have terminated
in accordance with the following sentence. The Option shall terminate upon any
of (i) the occurrence of either the Merger Effective Time or the Arrangement
Effective Time, (ii) if no notice pursuant to the preceding sentence has been
delivered prior thereto, the close of business on the day 18 months after the
date that Grantee becomes entitled to receive the CN Termination Fee (as defined
in the Combination Agreement) under Section 10.4(c) of the Combination
Agreement, (iii) the performance of the BNSF Stock Option Agreement (as defined
in the Combination Agreement) by Grantee or the right of Issuer to purchase
shares of Grantee's common stock upon exercise of the option granted thereunder
shall have been finally enjoined or held invalid by a court of competent
jurisdiction or (iv) the execution of or the written agreement to enter into an
agreement or series of agreements relating to a Business Combination Transaction
(as defined below) with such Holder; provided, however, that in the event that
any portion of the Option is held by any other person other than the Grantee in
accordance with the terms of this Agreement, any termination pursuant to clause
(iv) above shall only apply to such portion of the Option held by such Holder
and shall not effect that portion of the Option held by the Grantee or such
other persons, as the case may be. A "Business Combination Transaction" shall
mean (i) a consolidation, exchange of shares or merger of a Holder with any
Person and, in the case of a merger, in which the Holder shall not be the
continuing or surviving corporation, (ii) any transaction (including, without
limitation, a consolidation, exchange of shares or merger) in which the Holder
shall be the continuing or surviving corporation but the then outstanding shares
of capital stock of the Holder shall be changed into or exchanged for stock or
other securities of the Holder or any other Person or cash or any other property
or the capital stock of such Holder outstanding immediately before such
transaction shall after such transaction represent less than 50% of the common
shares and common share equivalents of such Holder outstanding immediately after
the transaction or (iii) a sale, lease or other transfer of all or substantially
all the assets of the Holder to any Person.

         (b) Triggering Event. A "Triggering Event" shall have occurred if the
Combination Agreement is terminated and Grantee shall have become entitled to
receive the CN Termination Fee pursuant to Section 10.4(c) of the Combination
Agreement.

<PAGE>

         (c) Notice of Triggering Event by Issuer. Issuer shall notify Grantee
promptly in writing of the occurrence of any Triggering Event, it being
understood that the giving of such notice by Issuer shall not be a condition to
the right of the Holder to exercise the Option.

         (d) Notice of Exercise by Grantee. If the Holder shall be entitled to
and wishes to exercise the Option, it shall send to Issuer a written notice (the
date of which is referred to in this Agreement as the "Notice Date") specifying
(i) the total number of shares that the Holder will purchase pursuant to such
exercise and (ii) a place and date (a "Closing Date") not earlier than three
business days nor later than 30 business days from the Notice Date for the
closing of such purchase (a "Closing"); provided, that if the Closing cannot be
effected by reason of the application of any law or regulation, (x) the Holder
or Issuer, as required, promptly after the giving of such notice shall file the
required notice, report, filing or application for approval and shall
expeditiously process the same and (y) the Closing Date shall be extended to not
later than the tenth business day following the expiration or termination of the
restriction imposed by such law. Each of the Holder and the Issuer agrees to use
its reasonable best efforts to cooperate with and provide information to Issuer
or Holder, as the case may be, for the purpose of any required notice, report,
filing or application for approval.

         (e) Payment of Purchase Price. At each Closing, the Holder shall pay to
Issuer the aggregate purchase price for the shares of Common Stock purchased
pursuant to the exercise of the Option in immediately available funds by a wire
transfer to a bank account designated by Issuer; provided, that failure or
refusal of Issuer to designate such a bank account shall not preclude the Holder
from exercising the Option, in whole or in part.

         (f) Delivery of Common Stock. At such Closing, simultaneously with the
payment of the purchase price by the Holder, Issuer shall deliver to the Holder
a certificate or certificates representing the number of shares of Common Stock
purchased by the Holder and, if the Option shall be exercised in part only, a
new Option evidencing the rights of the Holder to purchase the balance (as
adjusted pursuant to Section 1(b)) of the shares of Common Stock then
purchasable under this Agreement.

         (g) Restrictive Legend. Certificates for Common Stock delivered at a
Closing shall be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate is
         subject to resale restrictions arising under the Securities Act of
         1933, as amended, and the applicable Canadian securities laws."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if the Holder shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission, or a written opinion of counsel, in form and substance
reasonably satisfactory to Issuer, to the effect that such legend is not
required for purposes of either the Securities Act of 1933, as amended (the
"Securities Act") or the applicable Canadian securities laws. In addition, such
certificates shall bear any other legend as may be required by applicable law.
<PAGE>

         (h) Ownership of Record; Tender of Purchase Price; Expenses. Upon the
giving by the Holder to Issuer of a written notice of exercise referred to in
Section 2(d) and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not have been delivered to the
Holder. Issuer shall pay all expenses, and any and all United States and
Canadian federal, provincial, territorial, state and local taxes and other
charges that may be payable in connection with the preparation, issue and
delivery of stock certificates under this Section 2 in the name of the Holder or
its assignee, transferee or designee.

         (i) Effect of Statutory or Regulatory Restraints on Exercise. To the
extent that, upon or following the giving by the Holder to Issuer of a written
notice of exercise referred to in Section 2(d), Issuer is prohibited under
applicable law or regulation from delivering to the Holder a certificate or
certificates representing the number of shares of Common Stock purchased by the
Holder, Issuer shall immediately so notify the Holder in writing and thereafter
deliver or cause to be delivered, from time to time, to the Holder the portion
of the Option Shares that Issuer is no longer prohibited from delivering, within
two business days after the date on which it is no longer so prohibited;
provided, however, that upon notification by Issuer in writing of such
prohibition, the Holder may, at any time after receipt of such notification from
Issuer, revoke in writing its exercise notice, whether in whole or to the extent
of the prohibition, whereupon, in the latter case, Issuer shall promptly (i)
deliver to the Holder that portion of the Option Shares that Issuer is not
prohibited from delivering pursuant to the time periods set forth in Section
2(d); and (ii) deliver to the Holder, as appropriate, with respect to the
Option, a new Stock Option Agreement evidencing the right of the Holder to
purchase that number of shares of Common Stock for which the surrendered Stock
Option Agreement was exercisable at the time of giving the written notice of
exercise referred to in Section 2(d). Notwithstanding anything to the contrary
in this Agreement, the period for exercise of rights related to the Option set
forth in Section 2(a) shall be extended, at the request of Holder, for a period
not to exceed 180 days from the date that the Option would have terminated
pursuant to Section 2(a) hereof or such shorter period necessary to permit the
delivery of all the Option Shares subject to the exercise notice.

         (j) Conditions to Exercise. The obligation of the Issuer to effect the
Closing shall be subject to the following conditions:

                  (a)      all regulatory approvals required of the Issuer in
                           connection with the issuance of the Option Shares
                           hereunder shall have been obtained, including that
                           the grant of the Option and the issuance of the
                           Option Shares shall have been approved by The Toronto
                           Stock Exchange; and

                  (b)      the issuance of the Option Shares at the Closing
                           shall not be prohibited by any law, regulation,
                           injunction or order of any Governmental Entity (as
                           defined in the Combination Agreement).
<PAGE>

         (k) Waiver of Voting Rights. The Grantee agrees that it shall have no
voting rights, and shall not exercise or permit to be exercised any voting
rights in any circumstance, in respect of the Option or the Common Stock
purchasable under the Option unless, until, and only to the extent that the
Option has been exercised and Common Stock has actually been purchased
thereunder.

         3. Covenants of Issuer. In addition to its other agreements and
covenants in this Agreement, Issuer agrees:

                  (a) Shares Reserved for Issuance. It will maintain, free from
         preemptive rights, sufficient authorized but unissued shares of Common
         Stock to issue the appropriate number of shares of Common Stock
         pursuant to the terms of this Agreement so that the Option may be fully
         exercised without additional authorization of Common Stock after giving
         effect to all other options, warrants, convertible securities and other
         rights of third parties to purchase shares of Common Stock from Issuer.

                  (b) No Avoidance. It will not avoid or seek to avoid (whether
         by amendment of its constitutive documents or through reorganization,
         consolidation, merger, issuance of rights, dissolution or sale of
         assets, or by any other voluntary act) the observance or performance of
         any of the covenants, agreements or conditions to be observed or
         performed under this Agreement by Issuer.

                  (c) Further Assurances. After the date of this Agreement, it
         will promptly take all actions as may from time to time be required
         (including (i) seeking any necessary governmental approval, exemption
         or other authorization, (ii) complying with all applicable premerger
         notification, reporting and waiting period requirements under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and
         (iii) in the event that prior notice, report, filing or approval with
         respect to any Governmental Entity is necessary under any applicable
         foreign, United States or Canadian federal, provincial, territorial,
         state or local law before the Option may be exercised, cooperating
         fully with the Holder in preparing and processing the required
         applications or notices) in order to permit each Holder to exercise the
         Option and purchase shares of Common Stock pursuant to such exercise
         and to take all action necessary to protect the rights of the Holder
         against dilution.

                  (d) Stock Exchange Listing. It will use its reasonable best
         efforts to cause the shares of Common Stock to be issued pursuant to
         the Option to be approved for listing (to the extent they are not
         already listed) on all securities exchanges on which shares of Common
         Stock of the Issuer are then listed, subject to official notice of
         issuance.

         4. Representations and Warranties of Issuer. Issuer represents and
warrants to Grantee as follows:

                  (a) Shares Reserved for Issuance; Capital Stock. Issuer has
         taken all necessary corporate action to authorize and reserve, free
         from preemptive rights, and
<PAGE>

         permit it to issue, sufficient authorized but unissued shares of
         Common Stock so that the Option may be fully exercised without
         additional authorization of Common Stock after giving effect to all
         other options, warrants, convertible securities and other rights of
         third parties to purchase shares of Common Stock from Issuer, and all
         such shares, upon issuance pursuant to the Option, will be duly
         authorized, validly issued, fully paid and nonassessable, and will be
         delivered free and clear of all claims, liens, encumbrances, and
         security interests (other than those created by this Agreement) and
         not subject to any preemptive rights.

         5. Adjustments. In addition to the adjustment to the total number of
shares of Common Stock purchasable upon exercise of the Option pursuant to
Section 1(b), the total number of shares of Common Stock purchasable upon the
exercise of the Option shall be subject to adjustment from time to time as
follows:

                  (a) In the event of any change in the outstanding shares of
         Common Stock by reason of stock dividends, split-ups, mergers,
         recapitalizations, combinations, subdivisions, conversions, exchanges
         of shares or the like, the type and number of shares of Common Stock
         purchasable upon exercise of the Option, shall be appropriately
         adjusted, and proper provision shall be made in the agreements
         governing any such transaction, so that (i) any Holder shall receive
         upon exercise of the Option the number and class of shares, other
         securities, property or cash that such Holder would have received in
         respect of the shares of Common Stock purchasable upon exercise of the
         Option if the Option had been exercised and such shares of Common Stock
         had been issued to such Holder immediately prior to such event or the
         record date therefor, as applicable and (ii) in the event any
         additional shares of Common Stock are to be issued or otherwise become
         outstanding as a result of any such change (other than pursuant to an
         exercise of the Option), the number of shares of Common Stock
         purchasable upon exercise of the Option shall be increased so that,
         after such issuance and together with shares of Common Stock previously
         issued pursuant to the exercise of the Option (as adjusted on account
         of any of the foregoing changes in the Common Stock), the number of
         shares so purchasable equals the Maximum Applicable Percentage of the
         number of shares of Common Stock issued and outstanding immediately
         after the consummation of such change. If any such change in the
         outstanding shares of Common Stock occurs at any time on or after the
         first trading day included in the calculation of the Option Price and
         prior to the Closing, equitable adjustment shall be made to the Option
         Price to reflect the effect of such change.

                  (b) Without limiting the parties' relative rights and
         obligations under the Combination Agreement, in the event that Issuer
         enters into an agreement or arrangement (i) to consolidate with or
         merge into any person, other than Grantee or one of its subsidiaries,
         and Issuer will not be the continuing or surviving corporation in such
         consolidation or merger, (ii) to permit any person, other than Grantee
         or one of its subsidiaries, to merge into Issuer and Issuer will be the
         continuing or surviving corporation, but in connection with such
         merger, the shares of Common Stock outstanding immediately prior to the
         consummation of such merger will be changed into
<PAGE>

         or exchanged for stock or other securities of Issuer or any other
         person or cash or any other property, or the shares of Common Stock
         outstanding immediately prior to the consummation of such merger will,
         after such merger, represent less than 50% of the outstanding voting
         securities of the merged company, or (iii) to sell or otherwise
         transfer all or substantially all of its assets to any person, other
         than Grantee or one of its subsidiaries, then, and in each such case,
         the agreement governing such transaction will make proper provision so
         that the Option will, upon the consummation of any such transaction
         and upon the terms and conditions set forth herein, be converted into,
         or exchanged for, an option with identical terms appropriately
         adjusted to acquire the number and class of shares or other securities
         or property that Grantee would have received in respect of the Common
         Stock if the Option had been exercised immediately prior to such
         consolidation, merger, sale or transfer or the record date therefor,
         as applicable and make any other necessary adjustments.

         6. Registration. (a) Upon the occurrence of a Triggering Event, Issuer
shall, at the request of a Holder, as promptly as practicable prepare, file and
keep current a shelf registration statement under the Securities Act covering
any or all shares issued and issuable pursuant to the Option and shall use its
best efforts to cause such registration statement to become and remain effective
for such period as may be reasonably necessary to permit the sale or other
disposition of any shares of Common Stock issued upon total or partial exercise
of the Option ("Option Shares") in accordance with any plan of disposition
requested by such Holder; provided, however, that Issuer may suspend filing of
or maintaining the effectiveness of a registration statement relating to a
registration request by a Holder under this Section 6 for a period of time (not
in excess of 60 days in the aggregate) if in its judgment such filing of such
registration statement or the maintenance of its effectiveness would require the
disclosure of nonpublic information that Issuer has a good faith business
purpose for preserving as confidential. Subject to the foregoing, Issuer will
use its reasonable best efforts to cause such registration statement to become
effective as soon as practicable. In connection with any such registration,
Issuer and the Holder requesting such registration shall provide each other with
representations, warranties, indemnities and other agreements customarily given
in connection with such registrations. If requested by such Holder in connection
with such registration, Issuer shall become a party to any underwriting
agreement relating to the sale of such shares, but only to the extent of
obligating Issuer in respect of representations, warranties, indemnities,
contribution and other agreements customarily made by issuers in such
underwriting agreements.

         (b) In the event that such Holder so requests, the closing of the sale
or other disposition of the Common Stock or other securities pursuant to a
registration statement filed pursuant to Section 6(a) shall occur substantially
simultaneously with the exercise of the Option.

         (c) Any registration statement prepared and filed under this Section 6
and any sale covered thereby, will be at Issuer's expense except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of the Holder's counsel related thereto. In connection with any
registration pursuant to this Section 6, Issuer and such Holder will provide
each other and any underwriter of the offering with customary representations,
warranties, covenants, indemnification, and contribution in connection with such
registration.
<PAGE>

         7. Extension of Exercise Periods. The periods for exercise of certain
rights under Section 2 shall be extended in each such case at the request of the
Holder to the extent necessary to avoid liability by the Holder under Section
16(b) of the Securities Exchange Act of 1934, as amended ("Section 16(b)"), by
reason of such exercise.

         8. Assignment. Neither party may assign any of its rights or
obligations under this Agreement or the Option to any other person without the
express written consent of the other party. Any attempted assignment in
contravention of the preceding sentence shall be null and void.

         9. Filings; Other Actions. The parties hereto will use their reasonable
best efforts to make all filings with, and to obtain consents of, all third
parties and governmental authorities necessary for the consummation of the
transactions contemplated by this Agreement.

         10. Specific Performance. The parties acknowledge that damages would be
an inadequate remedy for a breach of this Agreement by either party and that the
obligations of the parties shall be specifically enforceable through injunctive
or other equitable relief.

         11. Severability. The provisions of this Agreement, the Combination
Agreement and any other agreement contemplated by the Combination Agreement
shall be deemed severable and the invalidity or unenforceability of any
provision of this Agreement, the Combination Agreement or any other agreement
contemplated by the Combination Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement or any provisions of
such other agreement. Without limiting the generality of the foregoing, the
invalidity or unenforceability of any provision of any such other agreement
shall not affect the validity or enforceability of any provision of this
Agreement. If any provision of this Agreement or any such other agreement or the
application thereof to any Person or any circumstance, is invalid or
unenforceable, (i) a suitable and equitable provision shall be substituted
therefor in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid or unenforceable provision and (ii) the
remainder of this Agreement or any such other agreement and the application of
such provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction. If for any reason a Governmental Entity
determines that the Holder is not permitted to acquire the full number of shares
of Common Stock provided in Section 1(a) of this Agreement (as adjusted pursuant
to Sections 1(b) and 5 of this Agreement), it is the express intention of Issuer
to allow the Holder to acquire or to require Issuer to repurchase such lesser
number of shares as may be permissible, without any amendment or modification of
this Agreement or any other agreement executed or to be executed in connection
herewith.

         12. Notices. Notices, requests, instructions or other documents to be
given under this Agreement shall be in writing and shall be deemed given, (i)
when sent, if sent by facsimile, provided that a copy of the facsimile is
promptly sent by U.S. mail and confirmation of receipt has been delivered (ii)
when delivered, if delivered personally to the intended recipient, and (iii)


<PAGE>

one business day later, if sent by overnight delivery via an international
courier service and, in each case at the respective addresses of the parties set
forth in the Combination Agreement.

         13. Expenses. Except as otherwise expressly provided in this Agreement
or in the Combination Agreement, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated by this Agreement shall be
paid by the party incurring such expense, including fees and expenses of its own
financial consultants, investment bankers, accountants, and counsel.

         14. Entire Agreement. This Agreement, the Confidentiality Agreement (as
defined in the Combination Agreement) and the Combination Agreement (including
any other exhibits thereto and the ancillary agreements contemplated thereby)
constitute the entire agreement, and supersede all other prior agreements,
understandings, representations and warranties, both written and oral, between
the parties, with respect to the subject matter of this Agreement. The terms and
conditions of this Agreement shall inure to the benefit of and be binding upon
the parties and their respective successors and permitted assigns. Nothing in
this Agreement is intended to confer upon any person or entity, other than the
parties to this Agreement, and their respective successors and permitted
assigns, any rights or remedies under this Agreement.

         15.      Governing Law and Venue; Waiver of Jury Trial.

         (a) This Agreement shall be deemed to be made in and in all respects
shall be interpreted, construed and governed by and in accordance with the laws
of the State of New York without regard to the conflict of law principles
thereof. The parties hereby irrevocably and unconditionally consent to submit to
the exclusive jurisdiction of both the courts of the State of Delaware and of
the United States of America located in Wilmington, Delaware (the "Delaware
Courts") and the Quebec Superior Court located in Montreal, Quebec (the "Quebec
Court") for any litigation arising out of or relating to this Agreement and the
transactions contemplated by this Agreement, waive any objection to the laying
of venue of any such litigation in the Delaware Courts or the Quebec Court and
agree not to plead or claim in any Delaware Court or the Quebec Court that such
litigation brought therein has been brought in an inconvenient forum; provided,
however, that the parties agree that any proceedings in the Quebec Court arising
out of or relating to this Agreement and the transactions contemplated by this
Agreement shall be conducted in English and all written documents relating to
any such proceedings shall be written in English.

         (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY
RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN THE
EVENT OF


<PAGE>

LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS
AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS
WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 15.

         16. U.S. Dollars. All amounts paid or payable hereunder, and all prices
referenced hereunder, shall be in United States Dollars.

         17. Captions. The Section and paragraph captions in this Agreement are
for convenience of reference only, do not constitute part of this Agreement and
shall not be deemed to limit or otherwise affect any of the provisions of this
Agreement.

ITEM 2B.
                                   Exhibit B

                                    FORM OF
                          BNSF STOCK OPTION AGREEMENT

         This STOCK OPTION AGREEMENT, dated as of December 18, 1999 (this
"Agreement"), is between BURLINGTON NORTHERN SANTA FE CORPORATION, a Delaware
corporation ("Issuer"), and CANADIAN NATIONAL RAILWAY COMPANY, a Canadian
corporation ("Grantee").


                                   RECITALS

         A. The Combination Agreement. Prior to the entry into this Agreement
and prior to the grant of the Option (as defined in Section 1(a)), Issuer,
Grantee, NORTH AMERICAN RAILWAYS, INC., a Delaware corporation owned 50% by
Issuer and 50% by Grantee ("Newco"), and Western Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Newco ("Merger Sub"), have
entered into a Combination Agreement, dated as of the date of this Agreement
(the "Combination Agreement"), pursuant to which Grantee and Issuer have
agreed to effect certain transactions upon the terms and subject to the
conditions set forth in the Combination Agreement.

         B. The Stock Option Agreement. As an inducement and condition to
Grantee's willingness to enter into the Combination Agreement, and in
consideration thereof, the board of directors of Issuer has approved the grant
to Grantee of the Option pursuant to this Agreement and the acquisition of
Common Stock (as defined below) by Grantee pursuant to this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth in this Agreement and in the Combination
Agreement, the parties agree as follows:

         1. The Option. (a) Issuer hereby grants to Grantee an irrevocable
option (the "Option") to purchase, subject to the terms and conditions of this
Agreement, up to 64,992,261 fully paid and nonassessable shares of common
stock, par value $0.01 per share ("Common Stock"), of Issuer at a price per
share in cash equal to the average of the closing price of Issuer's Common
Stock on the New York Stock Exchange (as reported in The Wall Street Journal,
New York City edition) on the five trading days ending on the last trading day
preceding the Notice Date (as defined below) (the "Option Price"); provided,
however, that in no event shall the number of shares for which the Option is
exercisable exceed 12.5% of the shares of Common Stock issued and outstanding
at the time of exercise (giving effect to the shares of Common Stock issued or
issuable under the Option) (the "Maximum Applicable Percentage"). The number
of shares of Common Stock purchasable upon exercise of the Option are subject
to adjustment as set forth in this Agreement.


<PAGE>


         (b) In the event that any additional shares of Common Stock are
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement), the aggregate number of shares of Common
Stock purchasable upon exercise of the Option (inclusive of shares, if any,
previously purchased upon exercise of the Option) shall automatically be
increased (without any further action on the part of Issuer or Grantee being
necessary) so that, after such issuance, it equals the Maximum Applicable
Percentage. No such increase shall affect the Option Price.

         2. Exercise; Closing. (a) Manner of Exercise; Termination. Grantee or
any other person that shall become a holder of all or part of the Option in
accordance with the terms of this Agreement (each such person being sometimes
referred to in this Agreement as the "Holder") may exercise the Option, in
whole or in part, by delivering a written notice thereof as provided in
Section 2(d) within 18 months following the occurrence of a Triggering Event
(as defined in Section 2(b)) unless prior to such Triggering Event either the
Merger Effective Time or the Arrangement Effective Time (as such terms are
defined in the Combination Agreement) shall have occurred or the Option shall
have terminated in accordance with the following sentence. The Option shall
terminate upon any of (i) the occurrence of either the Merger Effective Time
or the Arrangement Effective Time, (ii) if no notice pursuant to the preceding
sentence has been delivered prior thereto, the close of business on the day 18
months after the date that Grantee becomes entitled to receive the BNSF
Termination Fee (as defined in the Combination Agreement) under Section
10.4(b) of the Combination Agreement, (iii) the performance of the CN Stock
Option Agreement (as defined in the Combination Agreement) by Grantee or the
right of Issuer to purchase shares of Grantee's common stock upon exercise of
the option granted thereunder shall have been finally enjoined or held invalid
by a court of competent jurisdiction or (iv) the execution of or the written
agreement to enter into an agreement or series of agreements relating to a
Business Combination Transaction (as defined below) with such Holder;
provided, however, that in the event that any portion of the Option is held by
any other person other than the Grantee in accordance with the terms of this
Agreement, any termination pursuant to clause (iv) above shall only apply to
such portion of the Option held by such Holder and shall not effect that
portion of the Option held by the Grantee or such other persons, as the case
may be. A "Business Combination Transaction" shall mean (i) a consolidation,
exchange of shares or merger of a Holder with any Person and, in the case of a
merger, in which the Holder shall not be the continuing or surviving
corporation, (ii) any transaction (including, without limitation, a
consolidation, exchange of shares or merger) in which the Holder shall be the
continuing or surviving corporation but the then outstanding shares of capital
stock of the Holder shall be changed into or exchanged for stock or other
securities of the Holder or any other Person or cash or any other property or
the capital stock of such Holder outstanding immediately before such
transaction shall after such transaction represent less than 50% of the common
shares and common share equivalents of such Holder outstanding immediately
after the transaction or (iii) a sale, lease or other transfer of all or
substantially all the assets of the Holder to any Person.

         (b) Triggering Event. A "Triggering Event" shall have occurred if the
Combination Agreement is terminated and Grantee shall have become entitled to
receive the BNSF Termination Fee pursuant to Section 10.4(b) of the
Combination Agreement.


<PAGE>


         (c) Notice of Triggering Event by Issuer. Issuer shall notify Grantee
promptly in writing of the occurrence of any Triggering Event, it being
understood that the giving of such notice by Issuer shall not be a condition
to the right of the Holder to exercise the Option.

         (d) Notice of Exercise by Grantee. If the Holder shall be entitled to
and wishes to exercise the Option, it shall send to Issuer a written notice
(the date of which is referred to in this Agreement as the "Notice Date")
specifying (i) the total number of shares that the Holder will purchase
pursuant to such exercise and (ii) a place and date (a "Closing Date") not
earlier than three business days nor later than 30 business days from the
Notice Date for the closing of such purchase (a "Closing"); provided, that if
the Closing cannot be effected by reason of the application of any law or
regulation, (x) the Holder or Issuer, as required, promptly after the giving
of such notice shall file the required notice, report, filing or application
for approval and shall expeditiously process the same and (y) the Closing Date
shall be extended to not later than the tenth business day following the
expiration or termination of the restriction imposed by such law. Each of the
Holder and the Issuer agrees to use its reasonable best efforts to cooperate
with and provide information to Issuer or Holder, as the case may be, for the
purpose of any required notice, report, filing or application for approval.

         (e) Payment of Purchase Price. At each Closing, the Holder shall pay
to Issuer the aggregate purchase price for the shares of Common Stock
purchased pursuant to the exercise of the Option in immediately available
funds by a wire transfer to a bank account designated by Issuer; provided,
that failure or refusal of Issuer to designate such a bank account shall not
preclude the Holder from exercising the Option, in whole or in part.

         (f) Delivery of Common Stock. At such Closing, simultaneously with
the payment of the purchase price by the Holder, Issuer shall deliver to the
Holder a certificate or certificates representing the number of shares of
Common Stock purchased by the Holder and, if the Option shall be exercised in
part only, a new Option evidencing the rights of the Holder to purchase the
balance (as adjusted pursuant to Section 1(b)) of the shares of Common Stock
then purchasable under this Agreement.

         (g) Restrictive Legend. Certificates for Common Stock delivered at a
Closing shall be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate
         is subject to resale restrictions arising under the Securities Act of
         1933, as amended."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if the Holder shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission, or a written opinion of counsel, in form and substance
reasonably satisfactory to Issuer, to the effect that such legend is not
required for purposes of the Securities Act of 1933, as amended (the
"Securities Act"). In addition, such certificates shall bear any other legend
as may be required by applicable law.


<PAGE>

         (h) Ownership of Record; Tender of Purchase Price; Expenses. Upon the
giving by the Holder to Issuer of a written notice of exercise referred to in
Section 2(d) and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not have been delivered to the
Holder. Issuer shall pay all expenses, and any and all United States and
Canadian federal, provincial, territorial, state and local taxes and other
charges that may be payable in connection with the preparation, issue and
delivery of stock certificates under this Section 2 in the name of the Holder
or its assignee, transferee or designee.

         (i) Effect of Statutory or Regulatory Restraints on Exercise. To the
extent that, upon or following the giving by the Holder to Issuer of a written
notice of exercise referred to in Section 2(d), Issuer is prohibited under
applicable law or regulation from delivering to the Holder a certificate or
certificates representing the number of shares of Common Stock purchased by
the Holder, Issuer shall immediately so notify the Holder in writing and
thereafter deliver or cause to be delivered, from time to time, to the Holder
the portion of the Option Shares that Issuer is no longer prohibited from
delivering, within two business days after the date on which it is no longer
so prohibited; provided, however, that upon notification by Issuer in writing
of such prohibition, the Holder may, at any time after receipt of such
notification from Issuer, revoke in writing its exercise notice, whether in
whole or to the extent of the prohibition, whereupon, in the latter case,
Issuer shall promptly (i) deliver to the Holder that portion of the Option
Shares that Issuer is not prohibited from delivering pursuant to the time
periods set forth in Section 2(d); and (ii) deliver to the Holder, as
appropriate, with respect to the Option, a new Stock Option Agreement
evidencing the right of the Holder to purchase that number of shares of Common
Stock for which the surrendered Stock Option Agreement was exercisable at the
time of giving the written notice of exercise referred to in Section 2(d).
Notwithstanding anything to the contrary in this Agreement, the period for
exercise of rights related to the Option set forth in Section 2(a) shall be
extended, at the request of Holder, for a period not to exceed 180 days from
the date that the Option would have terminated pursuant to Section 2(a) hereof
or such shorter period necessary to permit the delivery of all the Option
Shares subject to the exercise notice.

         (j) Conditions to Exercise. The obligation of the Issuer to effect
the Closing shall be subject to the condition that the issuance of the Option
Shares at the Closing shall not be prohibited by any law, regulation,
injunction or order of any Governmental Entity (as defined in the Combination
Agreement).

         (k) Waiver of Voting Rights. The Grantee agrees that it shall have no
voting rights, and shall not exercise or permit to be exercised any voting
rights in any circumstance, in respect of the Option or the Common Stock
purchasable under the Option unless, until, and only to the extent that the
Option has been exercised and Common Stock has been actually purchased
thereunder.

         3. Covenants of Issuer. In addition to its other agreements and
covenants in this Agreement, Issuer agrees:


<PAGE>


                  (a) Shares Reserved for Issuance. It will maintain, free
         from preemptive rights, sufficient authorized but unissued shares of
         Common Stock to issue the appropriate number of shares of Common
         Stock pursuant to the terms of this Agreement so that the Option may
         be fully exercised without additional authorization of Common Stock
         after giving effect to all other options, warrants, convertible
         securities and other rights of third parties to purchase shares of
         Common Stock from Issuer.

                  (b) No Avoidance. It will not avoid or seek to avoid
         (whether by amendment of its constitutive documents or through
         reorganization, consolidation, merger, issuance of rights,
         dissolution or sale of assets, or by any other voluntary act) the
         observance or performance of any of the covenants, agreements or
         conditions to be observed or performed under this Agreement by
         Issuer.

                  (c) Further Assurances. After the date of this Agreement, it
         will promptly take all actions as may from time to time be required
         (including (i) seeking any necessary governmental approval, exemption
         or other authorization, (ii) complying with all applicable premerger
         notification, reporting and waiting period requirements under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and
         (iii) in the event that prior notice, report, filing or approval with
         respect to any Governmental Entity is necessary under any applicable
         foreign, United States or Canadian federal, provincial, territorial,
         state or local law before the Option may be exercised, cooperating
         fully with the Holder in preparing and processing the required
         applications or notices) in order to permit each Holder to exercise
         the Option and purchase shares of Common Stock pursuant to such
         exercise and to take all action necessary to protect the rights of
         the Holder against dilution.

                  (d) Stock Exchange Listing. It will use its reasonable best
         efforts to cause the shares of Common Stock to be issued pursuant to
         the Option to be approved for listing (to the extent they are not
         already listed) on all securities exchanges on which shares of Common
         Stock of the Issuer are then listed, subject to official notice of
         issuance.

         4. Representations and Warranties of Issuer. Issuer represents and
warrants to Grantee as follows:

                  (a) Shares Reserved for Issuance; Capital Stock. Issuer has
         taken all necessary corporate action to authorize and reserve, free
         from preemptive rights, and permit it to issue, sufficient authorized
         but unissued shares of Common Stock so that the Option may be fully
         exercised without additional authorization of Common Stock after
         giving effect to all other options, warrants, convertible securities
         and other rights of third parties to purchase shares of Common Stock
         from Issuer, and all such shares, upon issuance pursuant to the
         Option, will be duly authorized, validly issued, fully paid and
         nonassessable, and will be delivered free and clear of all claims,
         liens, encumbrances, and security interests (other than those created
         by this Agreement) and not subject to any preemptive rights.


<PAGE>


         5. Adjustments. In addition to the adjustment to the total number of
shares of Common Stock purchasable upon exercise of the Option pursuant to
Section 1(b), the total number of shares of Common Stock purchasable upon the
exercise of the Option shall be subject to adjustment from time to time as
follows:

                  (a) In the event of any change in the outstanding shares of
         Common Stock by reason of stock dividends, split-ups, mergers,
         recapitalizations, combinations, subdivisions, conversions, exchanges
         of shares or the like, the type and number of shares of Common Stock
         purchasable upon exercise of the Option, shall be appropriately
         adjusted, and proper provision shall be made in the agreements
         governing any such transaction, so that (i) any Holder shall receive
         upon exercise of the Option the number and class of shares, other
         securities, property or cash that such Holder would have received in
         respect of the shares of Common Stock purchasable upon exercise of
         the Option if the Option had been exercised and such shares of Common
         Stock had been issued to such Holder immediately prior to such event
         or the record date therefor, as applicable and (ii) in the event any
         additional shares of Common Stock are to be issued or otherwise
         become outstanding as a result of any such change (other than
         pursuant to an exercise of the Option), the number of shares of
         Common Stock purchasable upon exercise of the Option shall be
         increased so that, after such issuance and together with shares of
         Common Stock previously issued pursuant to the exercise of the Option
         (as adjusted on account of any of the foregoing changes in the Common
         Stock), the number of shares so purchasable equals the Maximum
         Applicable Percentage of the number of shares of Common Stock issued
         and outstanding immediately after the consummation of such change. If
         any such change in the outstanding shares of Common Stock occurs at
         any time on or after the first trading day included in the
         calculation of the Option Price and prior to the Closing, equitable
         adjustment shall be made to the Option Price to reflect the effect of
         such changes.

                  (b) Without limiting the parties' relative rights and
         obligations under the Combination Agreement, in the event that Issuer
         enters into an agreement or arrangement (i) to consolidate with or
         merge into any person, other than Grantee or one of its subsidiaries,
         and Issuer will not be the continuing or surviving corporation in
         such consolidation or merger, (ii) to permit any person, other than
         Grantee or one of its subsidiaries, to merge into Issuer and Issuer
         will be the continuing or surviving corporation, but in connection
         with such merger, the shares of Common Stock outstanding immediately
         prior to the consummation of such merger will be changed into or
         exchanged for stock or other securities of Issuer or any other person
         or cash or any other property, or the shares of Common Stock
         outstanding immediately prior to the consummation of such merger
         will, after such merger, represent less than 50% of the outstanding
         voting securities of the merged company, or (iii) to sell or
         otherwise transfer all or substantially all of its assets to any
         person, other than Grantee or one of its subsidiaries, then, and in
         each such case, the agreement governing such transaction will make
         proper provision so that the Option will, upon the consummation of
         any such transaction and upon the terms and conditions set forth
         herein, be converted into, or


<PAGE>


         exchanged for, an option with identical terms appropriately adjusted
         to acquire the number and class of shares or other securities or
         property that Grantee would have received in respect of the Common
         Stock if the Option had been exercised immediately prior to such
         consolidation, merger, sale or transfer or the record date therefor,
         as applicable and make any other necessary adjustments.

         6. Registration. (a) Upon the occurrence of a Triggering Event,
Issuer shall, at the request of a Holder, as promptly as practicable prepare,
file and keep current a shelf registration statement under the Securities Act
covering any or all shares issued and issuable pursuant to the Option and
shall use its best efforts to cause such registration statement to become and
remain effective for such period as may be reasonably necessary to permit the
sale or other disposition of any shares of Common Stock issued upon total or
partial exercise of the Option ("Option Shares") in accordance with any plan
of disposition requested by such Holder; provided, however, that Issuer may
suspend filing of or maintaining the effectiveness of a registration statement
relating to a registration request by a Holder under this Section 6 for a
period of time (not in excess of 60 days in the aggregate) if in its judgment
such filing of such registration statement or the maintenance of its
effectiveness would require the disclosure of nonpublic information that
Issuer has a good faith business purpose for preserving as confidential.
Subject to the foregoing, Issuer will use its reasonable best efforts to cause
such registration statement to become effective as soon as practicable. In
connection with any such registration, Issuer and the Holder requesting such
registration shall provide each other with representations, warranties,
indemnities and other agreements customarily given in connection with such
registrations. If requested by such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement
relating to the sale of such shares, but only to the extent of obligating
Issuer in respect of representations, warranties, indemnities, contribution
and other agreements customarily made by issuers in such underwriting
agreements.

         (b) In the event that such Holder so requests, the closing of the
sale or other disposition of the Common Stock or other securities pursuant to
a registration statement filed pursuant to Section 6(a) shall occur
substantially simultaneously with the exercise of the Option.

         (c) Any registration statement prepared and filed under this Section
6 and any sale covered thereby, will be at Issuer's expense except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of the Holder's counsel related thereto. In connection with any
registration pursuant to this Section 6, Issuer and such Holder will provide
each other and any underwriter of the offering with customary representations,
warranties, covenants, indemnification, and contribution in connection with
such registration.

         7. Extension of Exercise Periods. The periods for exercise of certain
rights under Section 2 shall be extended in each such case at the request of
the Holder to the extent necessary to avoid liability by the Holder under
Section 16(b) of the Securities Exchange Act of 1934, as amended ("Section
16(b)"), by reason of such exercise.

         8. Assignment. Neither party may assign any of its rights or
obligations under this Agreement or the Option to any other person without the
express written consent of the other


<PAGE>


party. Any attempted assignment in contravention of the preceding sentence
shall be null and void.

         9. Filings; Other Actions. The parties hereto will use their
reasonable best efforts to make all filings with, and to obtain consents of,
all third parties and governmental authorities necessary for the consummation
of the transactions contemplated by this Agreement.

         10. Specific Performance. The parties acknowledge that damages would
be an inadequate remedy for a breach of this Agreement by either party and
that the obligations of the parties shall be specifically enforceable through
injunctive or other equitable relief.

         11. Severability. The provisions of this Agreement, the Combination
Agreement and any other agreement contemplated by the Combination Agreement
shall be deemed severable and the invalidity or unenforceability of any
provision of this Agreement, the Combination Agreement or any other agreement
contemplated by the Combination Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement or any provisions of
such other agreement. Without limiting the generality of the foregoing, the
invalidity or unenforceability of any provision of any such other agreement
shall not affect the validity or enforceability of any provision of this
Agreement. If any provision of this Agreement or any such other agreement or
the application thereof to any Person or any circumstance, is invalid or
unenforceable, (i) a suitable and equitable provision shall be substituted
therefor in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid or unenforceable provision and (ii) the
remainder of this Agreement or any such other agreement and the application of
such provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction. If for any reason a Governmental Entity
determines that the Holder is not permitted to acquire the full number of
shares of Common Stock provided in Section 1(a) of this Agreement (as adjusted
pursuant to Sections 1(b) and 5 of this Agreement), it is the express
intention of Issuer to allow the Holder to acquire or to require Issuer to
repurchase such lesser number of shares as may be permissible, without any
amendment or modification of this Agreement or any other agreement executed or
to be executed in connection herewith.

         12. Notices. Notices, requests, instructions or other documents to be
given under this Agreement shall be in writing and shall be deemed given, (i)
when sent, if sent by facsimile, provided that a copy of the facsimile is
promptly sent by U.S. mail and confirmation of receipt has been delivered (ii)
when delivered, if delivered personally to the intended recipient, and (iii)
one business day later, if sent by overnight delivery via an international
courier service and, in each case at the respective addresses of the parties
set forth in the Combination Agreement.

         13. Expenses. Except as otherwise expressly provided in this
Agreement or in the Combination Agreement, all costs and expenses incurred in
connection with this Agreement and the transactions contemplated by this
Agreement shall be paid by the party incurring such expense, including fees
and expenses of its own financial consultants, investment bankers,
accountants, and counsel.


<PAGE>


         14. Entire Agreement. This Agreement, the Confidentiality Agreement
(as defined in the Combination Agreement) and the Combination Agreement
(including any other exhibits thereto and the ancillary agreements
contemplated thereby) constitute the entire agreement, and supersede all other
prior agreements, understandings, representations and warranties, both written
and oral, between the parties, with respect to the subject matter of this
Agreement. The terms and conditions of this Agreement shall inure to the
benefit of and be binding upon the parties and their respective successors and
permitted assigns. Nothing in this Agreement is intended to confer upon any
person or entity, other than the parties to this Agreement, and their
respective successors and permitted assigns, any rights or remedies under this
Agreement.

         15. Governing Law and Venue; Waiver of Jury Trial.

         (a) This Agreement shall be deemed to be made in and in all respects
shall be interpreted, construed and governed by and in accordance with the
laws of the State of New York without regard to the conflict of law principles
thereof. The parties hereby irrevocably and unconditionally consent to submit
to the exclusive jurisdiction of both the courts of the State of Delaware and
of the United States of America located in Wilmington, Delaware (the "Delaware
Courts") and the Quebec Superior Court located in Montreal, Quebec (the
"Quebec Court") for any litigation arising out of or relating to this
Agreement and the transactions contemplated by this Agreement, waive any
objection to the laying of venue of any such litigation in the Delaware Courts
or the Quebec Court and agree not to plead or claim in any Delaware Court or
the Quebec Court that such litigation brought therein has been brought in an
inconvenient forum; provided, however, that the parties agree that any
proceedings in the Quebec Court arising out of or relating to this Agreement
and the transactions contemplated by this Agreement shall be conducted in
English and all written documents relating to any such proceedings shall be
written in English.

         (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES
ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 15.

         16. U.S. Dollars. All amounts paid or payable hereunder, and all
prices referenced hereunder, shall be in United States Dollars.


<PAGE>


         17. Effectiveness. This Agreement shall not be effective until, but
shall become effective automatically immediately, without any action on the
part of Issuer, Grantee or any Holder, when, the Reciprocating Event (as
defined below) occurs. The "Reciprocating Event" shall mean the approval by
The Toronto Stock Exchange of both (i) the grant of the option granted to
Issuer by Grantee under the CN Stock Option Agreement and (ii) the issuance of
the shares of Grantee's common stock issuable thereunder.

         18. Captions. The Section and paragraph captions in this Agreement
are for convenience of reference only, do not constitute part of this
Agreement and shall not be deemed to limit or otherwise affect any of the
provisions of this Agreement.

             CANADIAN NATIONAL RAILWAY COMPANY, a corporation
             incorporated under the laws of Canada

             ("CN")

RECITALS:

A.  Newco and CN have agreed to enter into this Co-operation Agreement to ensure

    enterprise and the shareholders of Newco and CN are provided with equivalent
    economic returns;

B.  This Co-operation Agreement will govern the future operations and
    relationships of Newco and CN and sets out the governing principles of the

                                  ARTICLE A.1.
                         GOVERNANCE OF THE CORPORATIONS
C.1.1. Core Principles

        Each of Newco and CN agree that the Corporations shall be governed in a
manner that gives full effect to the following principles (the "Core
Principles"):

      D.1.1.1. Newco and CN shall each maintain its separate corporate existence
      but shall operate together as a single economic enterprise, and shall be
      managed on a unified basis for the benefit of the public shareholders of
      the two Corporations as a combined group;

      E.1.1.2. Members of the boards of directors and the Chief Executive
      Officer of Newco and CN will be identical and other members of senior
      management will be selected to allow the Corporations to be managed on a
      unified basis;

      F.1.1.3. Participating shares and voting shares of the Corporations, other
      than the CN Limited Voting Equity Shares, will be issued, traded and
      transferred together in the form of Trading Units, with the consequence
      that all holders of such shares (a) will benefit identically when
      dividends are declared or other distributions are made by either
      Corporation or on liquidation of either Corporation, and (b) will have the
      right to vote or to direct votes in each Corporation; and

      G.1.1.4. Newco shall comply with the provisions of the CN
      Commercialization Act as to the restriction on ownership of shares and the
      location of its head office and shall adopt the principles of the Official
      Languages Act (Canada) as provided herein.

H.1.2. Identicality of the Boards

        Each Corporation will do all acts and things necessary and within their
respective powers to ensure that the board of directors of Newco and the board
of directors of CN comprise the same individuals (the "Identicality Provision").
To that end, the Restated Certificate of Incorporation of Newco shall provide
that, subject to the amendment provisions contained therein, in order to be
qualified to be a member of the Newco board, an individual must be a member of
the CN board (the "Qualification Provision").

I.1.3. Governance

        In order that the Corporations shall be governed in accordance with the
Core Principles:

      J.1.3.1. Future Election of Directors and Directors' Meetings. The
      Corporations shall call and hold meetings of their respective shareholders
      to elect directors as close as possible in time, and shall cause to be
      nominated and proposed as management nominees the same slate of people to
      be elected as directors of each Corporation. Prior to each meeting of
      shareholders at which directors are to be elected, the nominating
      committee of each board will select and propose for approval by the boards
      of directors a common slate; provided that the slate shall be composed so
      as to comply with the requirements as to qualification and residency of
      directors contained in the incorporating legislation of both Corporations.
      Prior to any election or appointment of directors to be made by the boards
      of directors, including without limitation any appointment of a director
      to fill a vacancy on the boards, the nominating committee of each board
      will select and propose for election or appointment by the boards of
      directors, and the boards of directors shall elect or appoint, the same
      individual or individuals to each board, subject to compliance with the
      requirements as to qualification and residency of directors contained in
      the incorporating legislation of both Corporations.

      K.1.3.2. Charter Documents. The Restated Certificate of Incorporation of
      Newco shall be in the form attached as Exhibit H to the Combination
      Agreement and the articles of arrangement of CN shall be in the form
      attached hereto as Schedule A, and each shall contain:

         L.1.3.2.1. provisions imposing constraints on the issue, transfer and
         ownership, including joint ownership, of voting shares of the
         Corporation to prevent any one person, together with associates of that
         person, from holding, beneficially owning or controlling, directly or
         indirectly, otherwise than by way of security only, in the aggregate,
         voting shares to which are attached more than fifteen percent of the
         votes that may ordinarily be cast to elect directors of the
         Corporation;

         M.1.3.2.2. provisions respecting the enforcement of the constraints
         imposed pursuant to section 1.3.2.1; and

         N.1.3.2.3. provisions specifying that the head office of the
         Corporation is to be situated in the Montreal Urban Community, Quebec;

       in a manner that complies with and is subject to the exceptions contained
       in the CN Act, and such provisions may only be amended as provided in the
       Restated Certificate of Incorporation of Newco and the articles of
       incorporation of CN.

      O.1.3.3. By-Laws. The by-laws of each Corporation shall be in the form
      attached hereto as Schedule B. The board of directors of each Corporation
      may propose or make an amendment to its by-laws with respect to a matter
      which is treated in a similar manner in the by-laws of the other
      Corporation only if (a) a corresponding amendment is proposed or


<PAGE>

                                      - 4 -

      made to the by-laws of the other Corporation, or (b) such amendment is
      required to be made by law.

      P.1.3.4. Chair. The initial Chair of the board of directors of both
      Corporations shall be o, if he is willing and able to serve in that
      capacity. On an ongoing basis, the boards of directors of the Corporations
      shall agree on one person to be appointed as Chair of both boards of
      directors.

      Q.1.3.5. Board Committees. The board of directors of Newco and CN will
      establish identical committees of the board, including (without
      limitation) a nominating committee, audit committee and compensation
      committee. The members of the corresponding committees of the Corporations
      will be identical. Such number of the members of any such committees as
      may be required by the CBCA from time to time to be resident Canadians
      shall be resident Canadians.

      R.1.3.6. Chief Executive Officer. The initial Chief Executive Officer of
      both Corporations shall be o, if he is willing and able to serve in
      that capacity. On an ongoing basis, the boards of directors of the
      Corporations shall agree on one person to be appointed as the Chief
      Executive Officer of both Corporations.

      S.1.3.7. Management. Each Corporation will do, and agrees to cause each of
      its subsidiaries to do, all acts and things that may be necessary and
      desirable to ensure that the businesses of Newco and CN are managed on a
      unified basis for the benefit of the shareholders of the two Corporations
      as a combined group, including the appointment of common management at the
      senior executive level for both Corporations.

      T.1.3.8. Inter-Corporate Transactions. In consequence of the Core
      Principle that the Corporations should be operated as a single economic
      enterprise, no special board committee review, minority shareholder
      approval or other similar procedures for the protection of minority
      shareholders shall be required for transactions between Newco and its
      subsidiaries on the one hand and CN and its subsidiaries on the other.
      Notwithstanding any other provision of this Agreement, in any agreement,
      arrangement, dealing or transaction (a "Transaction") involving Newco (or
      a subsidiary of Newco) and CN (or a subsidiary of CN), the parties thereto
      shall agree to the amount and nature of any consideration to be paid by
      one to the other and to terms and conditions of the Transaction on the
      same basis as they would have agreed if they were dealing with each other
      at arm's length, unless the parties agree that in the circumstances it is
      not necessary or desirable to do so for any reason (including, without
      limiting the generality of the foregoing, the taxation laws applicable to
      either of them).

      U.1.3.9. English and French Language. Newco adopts the principles of
      Canadian bilingualism applicable to services provided by federal
      institutions as reflected in Parts IV and V of the Official Languages Act
      (Canada) and will endeavour to implement those principles in the offering
      of its services and the operation of its facilities in Canada.

                               SHAREHOLDER MATTERS

V.2.1. Place of Shareholder Meetings.

       Meetings of shareholders of the Corporations shall be held as close as
possible in time and at the same location, and shall be held at the registered
office of CN or at such other place within Canada as the directors of Newco and
CN may determine.

2.2    Record Date

       For all meetings of shareholders of the Corporations, the directors may
fix in advance a date as the record date for the purpose of determining
shareholders entitled to receive notice of the meetings of shareholders which,
in any case where the directors so fix a record date, shall be the same record
date for each Corporation. The directors shall not fail to fix a record date for
a meeting of shareholders if the effect under the incorporating legislation of
the Corporations would be to default to different record dates for the meetings
of shareholders of each Corporation.

2.3    Rights of Dissent

       If dissent rights are granted to shareholders of one of the Corporations
by the incorporating legislation of the Corporation or otherwise in connection
with the proposed approval of any matter by shareholders, the board of directors
of the other Corporation shall ensure that shareholders of that Corporation are
granted equivalent dissent rights.

2.4    CN Limited Voting Equity Shares

       The Corporations [and NAR Subco] agree that the voting rights attaching
to the CN Limited Voting Equity Shares shall be voted in a manner that is
consistent with the Core Principles.


                                  ARTICLE A.3.
                COVENANTS RELATING TO DIVIDENDS AND OTHER MATTERS

W.3.1. Dividends

      X.3.1.1. Subject to the articles of incorporation of CN, neither
      Corporation shall declare or pay any cash or stock dividends or make any
      distributions on shares comprising Trading Units unless the other
      Corporation shall simultaneously declare or pay, as the case may be, an
      identical or corresponding cash or stock dividend or distribution per
      share on the shares comprising the other Trading Units, except that (a) CN
      may elect to pay dividends in Canadian dollars in accordance with the CN
      Exchangeable Share Provisions, and Newco may elect to pay dividends in
      U.S. dollars, and (b) either Corporation may, in lieu of declaring a
      corresponding stock dividend, effect a corresponding subdivision of the CN
      Exchangeable Shares, CN Voting Shares and/or the Newco Common Shares, as
      the case may be.


<PAGE>

                                      - 6 -

      Y.3.1.2. Each Corporation will take all such actions and do all such
      things as are reasonably necessary, in co-operation with the other
      Corporation, to ensure that (i) the respective declaration date, record
      date and payment date for a dividend or distribution (or stock subdivision
      in lieu of a stock dividend) on its shares shall be the same as the
      declaration date, record date and payment date for a corresponding
      dividend or distribution (or stock subdivision in lieu of a stock
      dividend) on the other Corporation's shares.

      Z.3.1.3. If the boards of directors of the Corporations determine that a
      payment from one Corporation to the other is necessary or appropriate in
      connection with the payment of a dividend or the making of a distribution
      by the other Corporation, the relevant Corporation shall make an
      equalizing payment to the other Corporation sufficient to permit the other
      Corporation to pay the equivalent dividend or make the equivalent
      distribution.

AA.3.2. Other Covenants

      BB.3.2.1. Newco will take all such actions and do all such things as are
      reasonably necessary or desirable to enable and permit CN, in accordance
      with applicable law, to pay and otherwise perform its obligations with
      respect to the satisfaction of the Liquidation Amount or the Retraction
      Price in respect of each issued and outstanding CN Exchangeable Share upon
      the liquidation, dissolution or winding-up of CN or the delivery of a
      Retraction Request by a holder of CN Exchangeable Shares, as the case may
      be, including without limitation all such actions and all such things as
      are necessary or desirable to enable and permit CN to cause to be
      delivered Newco Common Shares to the holders of CN Exchangeable Shares in
      accordance with the provisions of Article 5 or 6, as the case may be, of
      the CN Exchangeable Share Provisions;

      CC.3.2.2. Newco will take all such actions and do all such things as are
      reasonably necessary or desirable to enable and permit Newco [NAR Subco],
      in accordance with applicable law, to perform Newco's [NAR Subco's]
      obligations arising upon the exercise by it of the Liquidation Call Right
      or the Retraction Call Right, including without limitation all such
      actions and all such things as are necessary or desirable to enable and
      permit Newco [NAR Subco] to cause Newco Common Shares to be issued to the
      holders of CN Exchangeable Shares in accordance with the provisions of the
      Liquidation Call Right or the Retraction Call Right, as the case may be;
      and

      DD.3.2.3. Neither Corporation shall initiate, propose or seek a voluntary
      liquidation, dissolution or winding up of the other Corporation unless it
      proposes to effect a substantially contemporaneous voluntary liquidation,
      dissolution or winding up of itself.

      EE.3.2.4. If Newco becomes a "specified financial institution" (as such
      term is defined in the Income Tax Act (Canada)) or does not deal at arm's
      length with such a person, Newco [NAR Subco] will exercise the Retraction
      Call Right if requested to do so by a holder of CN Exchangeable Shares
      making a Retraction Request who either alone or together with "specified
      persons" (as such term is defined in paragraph (h) of the definition of
      "taxable preferred share" in a subsection 248(l) of the Income Tax Act
      (Canada)) receives dividends in respect of more than 10% of the CN
      Exchangeable Shares.

FF.3.3. Reservation of Newco Common Shares

       Newco hereby represents, warrants and covenants in favour of CN that
Newco has reserved for issuance and will, at all times while any CN Exchangeable
Shares (other than CN Exchangeable Shares held by Newco or its Affiliates) are
outstanding, keep available, free from pre-emptive and other rights, out of its
authorized and unissued capital stock such number of Newco Common Shares (or
other shares or securities into which Newco Common Shares may be reclassified or
changed as contemplated by section 4.1 hereof) (a) as is equal to the sum of (i)
the number of CN Exchangeable Shares issued and outstanding from time to time

        The boards of directors of the Corporations shall determine, in good
faith and in their sole discretion, economic equivalence for the purposes of
sections 4.1, 4.2, 4.4 and 4.5, and each such determination shall be binding on

boards of directors of the Corporations may consider the factors set out in
section 3.5 of the CN Exchangeable Share Provisions.

4.7 Issuance of Shares

      4.7.1 Newco will issue Newco Common Shares only (i) upon exchange of CN

Principles.

4.9 Tender Offers

        In the event that a tender offer, take-over bid, share exchange offer,
share exchange bid, or similar transaction with respect to either Corporation
(an "Offer") is proposed to the Corporation or its shareholders, the Corporation
will use its reasonable efforts expeditiously and in good faith to take all such
actions and do all such things as are necessary or desirable to enable and
permit holders of the shares represented by Trading Units of the other
Corporation to participate in such Offer to the same extent and on an
economically equivalent basis as the holders of the shares of the Corporation,
without discrimination. Without limiting the generality of the foregoing, Newco
will use its reasonable efforts expeditiously and in good faith to ensure that
holders of CN Exchangeable Shares may participate in all such Offers without
being required to retract Exchangeable Shares (or, if so required, to ensure
that any such retraction shall be effective only upon, and shall be conditional
upon, the closing of the Offer and only to the extent necessary to tender or
deposit to the Offer).

"Self-Tender Offer") for its outstanding Trading Units (or for any of its shares
included in such Trading Units) unless a substantially contemporaneous
Self-Tender Offer for an equivalent percentage of the outstanding Trading Units
of the other Corporation is made on the same or corresponding terms; provided
that CN shall be entitled to offer to pay any cash consideration payable
thereunder in Canadian dollars and Newco shall be entitled to offer to pay any
cash consideration payable thereunder in U.S. dollars. In connection with any
such Self Tender Offers, the Corporations agree to make all commercially
reasonable efforts, including by seeking discretionary relief from applicable
securities regulatory authorities, to permit any pro-rationing of acceptances of
such Self-Tender Offers to occur on a basis which treats both Self-Tender Offers
as a single offer being made for a single class of securities.

4.11 No Transfer of CN Limited Voting Equity Shares

        Newco [NAR Subco] will not[, and Newco will ensure that [NAR Subco] does
not], sell, pledge, encumber or otherwise deal in the CN Limited Voting Equity
Shares except that Newco [NAR Subco] shall be permitted to transfer the CN
Limited Voting Equity Shares to a wholly-owned direct or indirect subsidiary of
Newco [NAR Subco] [or to another entity controlled and wholly-owned, directly or
indirectly, by Newco].

      material change or other filing required by a stock exchange or securities
      regulatory authority and will use all reasonable endeavours to ensure, as
      far as practicable, that the Corporations co-ordinate the content and
      timing of release of announcements.

             transferred by the holder thereof, without any further act or

<PAGE>


                                     -7-



             determine], in exchange for one Newco Common Share issued by

         (e) Simultaneously with the change in share capital under paragraph
             2.2(b) above, the transfer to and acquisition by Newco under
             paragraph 2.2(c) above of the Newco Elected Exchangeable Shares
             and the conversion under paragraph 2.2(d) above of the Newco

             have subscribed for and agreed to purchase and CN shall issue and
             sell to Newco one (1) CN Limited Voting Equity Share upon payment
             by Newco to CN of a sum equal to the closing trading price, per
             share, of the CN Common Shares on the TSE on the trading day

             by the Exchange Ratio.

             [NTD: References  to Newco in paragraphs (d) and (e) will be to NAR
             Subco if the parties  jointly  determine to make the exchange in
             paragraph (c) with NAR Subco.]

         (f) The holders of Newco Common Shares, other than those issued
             pursuant to the exchange provided for in paragraph 2.2(c) above,
             shall be deemed to have subscribed for and agreed to purchase at
             a purchase price of [$0.05] per share and CN shall issue to each
             such holder of Newco Common Shares, one (1) CN Voting Share for
             each Newco Common Share so held upon payment by Newco to CN of
             the aggregate subscription price therefor.

         (g) Newco shall issue to and deposit with the Trustee the Special
             Voting Share, in consideration of the payment to Newco of [$0.01]
             by CN, to be thereafter held of record by the Trustee as trustee
             for and on behalf of, and for the use and benefit of, the holders
             of the CN Exchangeable Shares in accordance with the Voting and
             Exchange Trust Agreement.

         (h) Each CN Option shall be exchanged  for an option (a "Replacement
             Option ") to purchase a number of Newco Stapled Units equal to
             the product of the Exchange Ratio multiplied by the number of CN
             Common Shares subject to such CN Option. Such Replacement Option
             shall provide for an exercise price per Newco Stapled Unit equal
             to the


<PAGE>


                                     -8-


             exercise price per CN Common Share of such CN Option immediately
             prior to the Arrangement Effective Time divided by the Exchange
             Ratio. If the foregoing calculation results in a Replacement
             Option being exerciseable for a fraction of a Newco Stapled Unit,
             then the number of Newco Stapled Units subject to such
             Replacement Option shall be rounded up to the next whole number
             of Newco Stapled Units and the total exercise price for the
             Replacement Option will be increased by the exercise price of the
             fractional Newco Stapled Unit. The term to expiry, conditions to
             and manner of exercising, vesting schedule, and all other terms
             and conditions of such Replacement Option will otherwise be
             unchanged from those which prevailed prior to the implementation
             of the Merger and the Arrangement, and any document or agreement
             previously evidencing a CN Option shall thereafter evidence and
             be deemed to evidence such Replacement Option.

         (i) The authorized share capital of CN shall be amended by the
             elimination of the CN Common Shares as a class of authorized
             shares.

         (j) The By-laws of CN shall be amended as set forth in Appendix IV.

Section 2.3  Exchange Elections and Deemed Elections.

a portion of such shares, to make an election at or prior to the Election
Deadline to exchange all or any CN Exchangeable Shares issuable to such holder
pursuant to the Arrangement for Newco Common Shares, on the basis provided for
in this Plan of Arrangement and in the Letter of Transmittal and Election
Form. Notwithstanding the foregoing, each holder of CN Common Shares who is
not a resident of Canada for purposes of the ITA will be deemed to have
elected to exchange all of the CN Exchangeable Shares issuable to such holder
pursuant to the Arrangement for Newco Common Shares on the basis provided for
in this Plan of Arrangement, and such holders' CN Exchangeable Shares shall be
deemed for all purposes to be Newco Elected Exchangeable Shares, except where
and to the extent that such non-resident holder specifically elects in a
Letter of Transmittal and Election form received prior to the Election
Deadline not to have such exchange occur.

Section 2.4  Stated Capital.

         The stated capital accounts of CN shall be dealt with as follows:

         (a) The amount of the stated capital account attributable to the CN
             Voting Shares following the Arrangement shall be equal to the sum
             of: (i) the aggregate subscription price for the CN Voting Shares

             to paragraph 2.2(f), and (ii) the product of [$0.05] multiplied
             by the number of CN Voting Shares issued upon the change of the
             CN Common Shares pursuant to paragraph 2.2(b).

         (b) The amount of the stated capital account attributable to the CN
             Exchangeable Shares initially shall be equal to the amount of the
             stated capital account attributable to the CN Common Shares
             immediately prior to the Arrangement Effective Time less the
             amount added to the stated capital account attributable to the CN
             Voting Shares under paragraph 2.4(a)(ii).

             into CN Limited Voting Equity Shares pursuant to paragraph
             2.2(d), the stated capital account attributable to the CN
             Exchangeable Shares shall be reduced by an amount (the "CN
             Limited Voting Equity Share Converted Stated Capital Amount")
             equal to the amount provided for in paragraph 2.4(b) (being the
             amount of the stated capital account initially attributable to
             the CN Exchangeable Shares) multiplied by a fraction, the
             numerator of which is the number of Newco Elected Exchangeable
             Shares and the denominator of which is the number of CN Common
             Shares outstanding immediately prior to the Arrangement Effective
             Time.

         (d) The amount of the stated capital account attributable to the CN
             Limited Voting Equity Shares following the Arrangement shall be
             the CN Limited Voting Equity Share Converted Stated Capital
             Amount plus the amount of the subscription price of the one (1)
             CN Limited Voting Equity Share issued pursuant to paragraph
             2.2(e) above.

holders of CN Common Shares pursuant to the change in share capital pursuant
to paragraph 2.2(b) shall, and shall for all purposes be deemed to, consist of

Shares are changed together with all of the rights attached to the CN Voting
Shares, the CN Exchangeable Shares and the CN Stapled Units representing same
pursuant to the Voting and Exchange Trust Agreement, this Plan of Arrangement,

in section 190 of the CBCA and this section 3.1 (the "Dissent Procedures") in
connection with the Arrangement; provided that, notwithstanding subsection
190(5) of the CBCA, the written objection to the Arrangement Resolution
referred to in subsection 190(5) of the CBCA must be received by CN not later
than [5:00 p.m. (Montreal time)] on the Business Day preceding the CN
Shareholders Meeting. Holders of CN Common Shares who duly exercise such rights
of dissent and who:

         (a) are ultimately entitled to be paid fair value for their CN
             Common Shares shall be deemed to have transferred such CN Common
             Shares to CN immediately prior to the Arrangement Effective Time
             to the extent the fair value thereof is paid by CN, and such
             shares shall be cancelled on the Arrangement Effective Date; or

         (b) are ultimately not entitled, for any reason, to be paid fair value
             for their CN Common Shares shall be deemed to have participated
             in the Arrangement on the same basis as a non-dissenting holder
             of CN Common Shares and shall receive CN Voting Shares and CN
             Exchangeable Shares, which may be deemed to be Newco Elected
             Exchangeable Shares and to have been exchanged for Newco Common
             Shares, all in accordance with sections 2.2 and 2.3,

but in no case shall CN or any other Person be required to recognize such
holders, or any other person, as holders of CN Common Shares after the
Arrangement Effective Time and the names of such holders of CN Common Shares
shall be deleted from the share register of CN in respect of the CN Common
Shares at the Arrangement Effective Time.

                           AND SETTLEMENT PROCEDURES

Section 4.1  Issuance of Unit Certificates Representing CN Exchangeable Shares
and CN Voting Shares.

         At or promptly after the Arrangement Effective Time, CN shall deposit
with the Depositary, as custodian for the benefit of the holders of CN Common
Shares who will receive CN Exchangeable Shares and CN Voting Shares pursuant
to the Arrangement, other than holders of Newco Elected Exchangeable Shares,
CN Stapled Unit certificates representing the CN Exchangeable Shares and CN
Voting Shares issued pursuant to paragraph 2.2(b) upon the change of the CN
Common Shares. Upon surrender to the Depositary for cancellation of a
certificate which immediately prior to the Arrangement Effective Time
represented one or more CN Common Shares that were so changed into CN Voting
Shares and CN Exchangeable Shares under the Arrangement (and were not Newco
Elected Exchangeable Shares), together with such other documents and
instruments as would have been required to effect the transfer of the shares
formerly represented by such certificate under the CBCA and the By-laws of CN
and such additional documents and instruments as the Depositary may reasonably
require, the holder of such surrendered certificate shall be entitled to
receive in exchange therefor, and the Depositary shall deliver to such holder,
a certificate representing that number (rounded down to the nearest whole
number) of CN Stapled Units representing the number (rounded down to the
nearest whole number) of CN Exchangeable Shares and CN Voting Shares which
such holder has the right to receive (together with any dividends or
distributions with respect thereto pursuant to section 4.3 and any cash
representing that holder's pro rata entitlement to the proceeds of the sale of
fractional CN Stapled Units pursuant to section 4.7), and the certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of CN Common Shares (except CN Common Shares that were changed into
Newco Elected Exchangeable Shares and CN Voting Shares) that is not registered
in the transfer records of CN, a certificate representing the proper number of
CN Stapled Units may be issued to the transferee if the certificate
representing such CN Common Shares is presented to the Depositary, accompanied
by all documents required to evidence and effect such transfer. Until
surrendered as contemplated by this section 4.1, each certificate which
immediately prior to the Arrangement Effective Time represented CN Common
Shares (except CN Common Shares that were changed into Newco Elected
Exchangeable Shares and CN Voting Shares) shall be deemed at all times after
the Arrangement Effective Time to represent only the right to receive upon
such surrender (i) the CN Stapled Unit certificate representing CN
Exchangeable Shares and CN Voting Shares as contemplated by this section 4.1,
(ii) a cash payment representing that holder's pro rata entitlement to the
proceeds of the sale of fractional CN Stapled Units pursuant to section 4.7,
and (iii) any dividends or


<PAGE>


                                     -12-

distributions with a record date after the Arrangement Effective Time
theretofore paid or payable with respect to CN Exchangeable Shares as
contemplated by section 4.3.

Section 4.2  Issue of Unit Certificates Representing Newco Common Shares and CN
Voting Shares.

         At or promptly after the Arrangement Effective Time, Newco, [NAR
Subco] and CN shall jointly cause to be deposited Newco Stapled Unit
certificates (representing the Newco Common Shares and the CN Voting Shares
issued pursuant to the Merger and the Plan of Arrangement) with the
Depositary, as custodian for the benefit of the: (i) former holders of BNSF
Common Shares who received Newco Common Shares pursuant to the Merger and CN
Voting Shares under the Arrangement pursuant to paragraph 2.2(f) of this Plan
of Arrangement, and (ii) former holders of CN Common Shares who received Newco
Elected Exchangeable Shares and CN Voting Shares pursuant to the Plan of
Arrangement. Upon surrender to the Depositary for cancellation of a
certificate which immediately prior to the Arrangement Effective Time
represented outstanding CN Common Shares that were changed into CN Voting
Shares and Newco Elected Exchangeable Shares, together with such other
documents and instruments as would have been required under the CBCA and CN's
By-laws, to effect the transfer of the shares formerly represented by such
certificates and such additional documents and instruments as the Depositary
may reasonably require, the holder of such a surrendered certificate shall be
entitled to receive in exchange therefor, and the Depositary shall deliver to
such holder, a certificate representing that number (rounded down to the
nearest whole number) of Newco Stapled Units representing the number (rounded
down to the nearest whole number) of Newco Common Shares and CN Voting Shares
which such holder has the right to receive (together with any dividends or
distributions with respect thereto pursuant to section 4.3 and any cash
representing that holder's pro rata entitlement to the proceeds of the sale of
fractional Newco Stapled Units pursuant to section 4.7), and the certificate
so surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of CN Common Shares which is not registered in the transfer records
of CN, a Newco Stapled Unit certificate representing the proper number of
Newco Common Shares and CN Voting Shares may be issued to the transferee if
the certificate representing such CN Common Shares is presented to the
Depositary, accompanied by all documents required to evidence and effect such
transfer. Until surrendered as contemplated by this section 4.2, each
certificate which immediately prior to the Arrangement Effective Time
represented one or more outstanding CN Common Shares that were changed into CN
Voting Shares and Newco Elected Exchangeable Shares shall be deemed at all
times after the Arrangement Effective Time to represent only the right to
receive upon such surrender (i) the Newco Stapled Unit certificate
representing Newco Common Shares and CN Voting Shares as contemplated by this
section 4.2, (ii) a cash payment representing that holder's pro


<PAGE>


                                     -13-

rata entitlement to the proceeds of the sale of fractional Newco Stapled Units
pursuant to section 4.7, and (iii) any dividends or distributions with a
record date after the Arrangement Effective Time theretofore paid or payable
with respect to Newco Common Shares as contemplated by section 4.3.

Section 4.3  Distributions with Respect to Unsurrendered Certificates.

         No dividends or other distributions declared or made after the
Arrangement Effective Time with respect to CN Exchangeable Shares or Newco
Common Shares, as applicable, with a record date after the Arrangement
Effective Time shall be paid to the holder of any unsurrendered certificate
which immediately prior to the Arrangement Effective Time represented
outstanding CN Common Shares that were changed or changed and exchanged, as
applicable, pursuant to section 2.2, unless and until the holder of record of
such certificate shall surrender such certificate in accordance with section
4.1 or 4.2, as applicable. Subject to applicable law, at the time of such
surrender of any such certificate, there shall be paid to the holder of record
of the certificates formerly representing CN Common Shares, without interest,
(i) the amount of dividends or other distributions with a record date after
the Arrangement Effective Time theretofore paid with respect to such CN
Exchangeable Share or Newco Common Share, as the case may be, and (ii) on the
appropriate payment date, the amount of dividends or other distributions with
a record date after the Arrangement Effective Time but prior to surrender and
a payment date subsequent to surrender payable with respect to such CN
Exchangeable Share or Newco Common Share, as the case may be.

Section 4.4  Stapling of CN Voting Shares.

         The Articles of Arrangement of CN shall provide as follows. Except as
expressly provided in this Plan of Arrangement and in this section 4.4, no CN
Voting Share shall be or shall be capable of being issued, transferred,
transmitted or otherwise alienated or disposed of separately from and
otherwise than as part of either: (i) a CN Stapled Unit comprised of an equal
number of CN Voting Shares and CN Exchangeable Shares, or (ii) a Newco Stapled
Unit comprised of an equal number of CN Voting Shares and Newco Common Shares.
Except as expressly provided in this Plan of Arrangement and in this section
4.4, no CN Exchangeable Share shall be or shall be capable of being issued,
transferred, transmitted or otherwise alienated or disposed of separately from
and otherwise than as part of a CN Stapled Unit comprised of an equal number
of CN Voting Shares and CN Exchangeable Shares. Notwithstanding the foregoing,
the following issuances and transfers of CN Voting Shares otherwise than as
part of a CN Stapled Unit or Newco Stapled Unit are hereby expressly
permitted:

               (i)   the issuances of CN Voting Shares provided in Section 2.2;

              (ii)   [NTD - other?]

                                     -14-



Notwithstanding the foregoing, the following issuances and transfers of CN
Exchangeable Shares otherwise than as part of a CN Stapled Unit are hereby
expressly permitted:

             (iii)   the issuances of CN Exchangeable Shares provided in
                     Section 2.2;

              (iv)   the transfers of CN Exchangeable Shares to Newco [NAR
                     Subco] and the conversion thereof to CN Limited Voting
                     Equity Shares provided in Section 2.2;

               (v)   the redemption of CN Exchangeable Shares by CN upon a
                     retraction of the CN Exchangeable Shares in accordance
                     with the CN Exchangeable Share Provisions;

              (vi)   the transfer of CN Exchangeable Shares to [NAR Subco
                     and/or] Newco, as applicable, pursuant to its exercise or
                     deemed exercise of a Retraction Call Right, the
                     Liquidation Call Right, the Exchange Right or the
                     Automatic Exchange Rights in accordance with the CN
                     Exchangeable Share Provisions, the Plan of Arrangement
                     and/or the Voting and Exchange Trust Agreement, as
                     applicable.

             (vii)   [NTD - other?]

Without limiting the generality of the foregoing, CN shall be entitled to
treat the registered holder of CN Stapled Units (or, subject to such Person
furnishing such information as is described in subsection 77(4) of the CBCA or
any replacement or successor provision therefor, the executor, administrator,
heir or legal representative of the heirs, of the estate of a deceased holder,
a guardian, committee, trustee, curator or tutor representing a holder who is
an infant, an incompetent person or a missing person, or a liquidator of or a
trustee in bankruptcy for a holder) as the owner exclusively entitled to vote,
to receive notices, to receive dividends or other payments in respect of and
otherwise to exercise all the rights and powers of the owner of the CN Voting
Shares and the CN Exchangeable Shares represented by such CN Stapled Unit. For
purposes of establishing and maintaining the share register for the
outstanding CN Voting Shares, CN and its Transfer Agent shall and shall be
entitled at all times (subject only to the exercise of the Liquidation Call
Right) to treat each registered holder of CN Stapled Units and of Newco
Stapled Units as the registered holder of a number of CN Voting Shares equal
to the aggregate number of CN Stapled Units and Newco Stapled Units held by
such Person. For purposes of establishing and maintaining the share register
for the outstanding CN Exchangeable Shares, CN and its Transfer Agent shall
and shall be entitled, at all times (subject only to the Liquidation Call
Right, the Exchange Right


<PAGE>


                                     -15-

and the Automatic Exchange Rights and except where a holder of CN Stapled
Units representing CN Exchangeable Shares has submitted a Retraction Request
in respect of CN Exchangeable Shares represented by such CN Stapled Unit
certificate) to treat each registered holder of CN Stapled Units as the
registered holder of a number of CN Exchangeable Shares equal to the number of
CN Stapled Units held by such Person. Without limiting the generality of the
foregoing, a CN Stapled Unit certificate shall be the security certificate,
and the only security certificate, that a holder of CN Voting Shares and CN
Exchangeable Shares comprising such CN Stapled Units shall be entitled to
receive in respect of his or her holding of CN Voting Shares and CN
Exchangeable Shares pursuant to the CBCA or otherwise and a Newco Stapled Unit
certificate shall be the security certificate, and the only security
certificate, that a holder of CN Voting Shares and Newco Common Shares
comprising such Newco Stapled Unit shall be entitled to receive in respect of
his or her holding of CN Voting Shares pursuant to the CBCA or otherwise.

Section 4.5  Lost Certificates.

         In the event any certificate which immediately prior to the
Arrangement Effective Time represented one or more outstanding CN Common
Shares that were changed and, if applicable, exchanged pursuant to section 2.2
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such certificate to be lost, stolen or
destroyed, the Depositary will issue in exchange for such lost, stolen or
destroyed certificate, one or more CN Stapled Unit certificates or Newco
Stapled Unit certificates representing one or more CN Exchangeable Shares and
CN Voting Shares or Newco Common Shares and CN Voting Shares (and any
dividends or distributions with respect thereto and any entitlements of the
holder thereof to the proceeds of sale of fractional CN Stapled Units or Newco
Stapled Units pursuant to section 4.7) issuable and deliverable in accordance
with the Plan of Arrangement and such holder's Letter of Transmittal and
Election Form. When authorizing such payment in exchange for any lost, stolen
or destroyed certificate, the Person to whom such unit certificates are to be
issued shall, as a condition precedent to the issuance thereof, give a bond
satisfactory to CN and/or Newco, as applicable, and their respective transfer
agents in such sum as CN and/or Newco, as applicable, may direct or otherwise
indemnify CN and Newco in a manner satisfactory to CN and/or Newco, as
applicable, against any claim that may be made against CN and/or Newco, as
applicable, with respect to the certificate alleged to have been lost, stolen
or destroyed.

Section 4.6  Withholding Rights.

         CN, Newco, [NAR Subco] and the Depositary shall be entitled to deduct
and withhold from any dividend or consideration otherwise payable to any
holder of CN Stapled Units representing CN Exchangeable Shares or Newco
Stapled Units representing Newco Common Shares such amounts as CN, Newco, [NAR
Subco] or


<PAGE>


                                     -16-

the Depositary is required or permitted to deduct and withhold with respect to
such payment under the ITA, the United States Internal Revenue Code of 1986 or
any provision of provincial, state, local or foreign tax law, in each case, as
amended. To the extent that amounts are so withheld, such withheld amounts
shall be treated for all purposes hereof as having been paid to the holder of
the shares in respect of which such deduction and withholding was made,
provided that such withheld amounts are actually remitted to the appropriate
taxing authority. To the extent that the amount so required or permitted to be
deducted or withheld from any payment to a holder exceeds the cash portion of
the consideration otherwise payable to the holder, CN, Newco, [NAR Subco] and
the Depositary are hereby authorized to sell or otherwise dispose of such
portion of the consideration as is necessary to provide sufficient funds to
CN, Newco, [NAR Subco] or the Depositary, as the case may be, to enable it to
comply with such deduction or withholding requirement and CN, Newco, [NAR
Subco] or the Depositary shall notify the holder thereof and remit any
unapplied balance of the net proceeds of such sale.

Section 4.7  No Fractional Units.

         No certificates or scrip representing fractional CN Stapled Units,
fractional Newco Stapled Units, fractional CN Exchangeable Shares, fractional
CN Voting Shares or fractional Newco Common Shares shall be issued or
delivered upon the surrender for exchange of certificates pursuant to section
4.1 or 4.2 and such fractional interests shall not entitle the owner thereof
to exercise any rights as a security holder of CN or Newco. In lieu of any
such fractional securities:

         (a) each Person  otherwise entitled to a fractional interest in a CN
             Stapled Unit (comprising a fractional interest in a CN Voting
             Share and a fractional interest in a CN Exchangeable Share) will
             receive a cash payment equal to such Person's pro rata portion of
             the net proceeds after expenses received by the Depositary upon
             the sale of whole units representing an accumulation of all
             fractional interests in CN Stapled Units to which all such
             Persons would otherwise be entitled. The Depositary will sell
             such CN Stapled Units on the TSE as soon as reasonably
             practicable following the Arrangement Effective Date. The
             aggregate net proceeds after expenses of such sale will be
             distributed by the Depositary, pro rata in relation to the
             respective fractions, among the Persons otherwise entitled to
             receive fractional interests in CN Stapled Units; and

         (b) each Person otherwise entitled to a fractional interest in a Newco
             Stapled Unit (comprising a fractional interest in a CN Voting
             Share and a fractional interest in a Newco Common Share) will
             receive a cash payment equal to such Person's pro rata portion of
             the net proceeds after expenses received by the Depositary upon
             the sale of whole units


<PAGE>


                                     -17-

             representing an accumulation of all fractional interests in Newco
             Stapled Units to which all such Persons would otherwise be
             entitled. The Depositary will sell such Newco Stapled Units on
             the NYSE as soon as reasonably practicable following the
             Arrangement Effective Date. The aggregate net proceeds after
             expenses of such sale will be distributed by the Depositary, pro
             rata in relation to the respective fractions, among the Persons
             otherwise entitled to receive fractional interests in Newco
             Stapled Units.

                                  ARTICLE 5
        CERTAIN RIGHTS OF [NAR SUBCO] TO ACQUIRE CN EXCHANGEABLE SHARES

Section 5.1  [NAR Subco] Liquidation Call Right.

         (a) [NAR Subco] shall have the overriding  right (the "Liquidation Call
             Right "), in the event of and notwithstanding the proposed
             liquidation, dissolution or winding-up of CN pursuant to Article
             5 of the CN Exchangeable Share Provisions, to purchase from all
             but not less than all of the holders of CN Stapled Units
             representing CN Exchangeable Shares (other than any holder which
             is an Affiliate of Newco as defined in the CN Exchangeable Share
             Provisions) on the Liquidation Date all but not less than all of
             the CN Exchangeable Shares held by each such holder on payment by
             [NAR Subco] of an amount per share (the "Liquidation Call
             Purchase Price ") equal to the Current Market Price of a Newco
             Stapled Unit on the last Business Day prior to the Liquidation
             Date, which shall be satisfied in full by [NAR Subco] causing to
             be issued to such holder one Newco Common Share, and, to the
             extent not paid by CN, paid to such holder an additional amount
             equivalent to the full amount of all declared and unpaid
             dividends on each such CN Exchangeable Share held by such holder
             on any dividend record date which occurred prior to the date of
             purchase by [NAR Subco] (the "Dividend Amount "). In the event of
             the exercise of the Liquidation Call Right by [NAR Subco], each
             holder shall be obligated to sell all the CN Exchangeable Shares
             represented by the CN Stapled Units held by such holder to [NAR
             Subco] on the Liquidation Date on payment by [NAR Subco] to such
             holder of the Liquidation Call Purchase Price for each such
             share, and CN shall have no obligation to redeem such shares so
             purchased by [NAR Subco].

         (b) To exercise the Liquidation Call Right, [NAR Subco] must notify
             CN's transfer agent (the "Transfer Agent "), as agent for the
             holders of CN Stapled Units representing CN Exchangeable Shares,
             and CN of [NAR


<PAGE>


                                     -18-

             Subco's] intention to exercise such right at least 45 days before
             the Liquidation Date in the case of a voluntary liquidation,
             dissolution or winding-up of CN and at least five Business Days
             before the Liquidation Date in the case of an involuntary
             liquidation, dissolution or winding-up of CN. The Transfer Agent
             will notify the holders of CN Stapled Units representing CN
             Exchangeable Shares as to whether or not [NAR Subco] has
             exercised the Liquidation Call Right forthwith after the expiry
             of the period during which the same may be exercised by [NAR
             Subco]. If [NAR Subco] exercises the Liquidation Call Right, then
             on the Liquidation Date [NAR Subco] will purchase and the holders
             will sell all of the CN Exchangeable Shares then outstanding for
             a price per share equal to the Liquidation Call Purchase Price.

         (c) For the purposes of completing the purchase of the CN Exchangeable
             Shares pursuant to the Liquidation Call Right, Newco and [NAR
             Subco] shall jointly cause to be deposited with the Transfer
             Agent, on or before the Liquidation Date, certificates
             representing the aggregate number of Newco Common Shares to which
             holders of CN Exchangeable Shares are entitled upon such exchange
             and a cheque or cheques of [NAR Subco] payable at par at any
             branch of the bankers of [NAR Subco] representing the aggregate
             Dividend Amount in payment of the total Liquidation Call Purchase
             Price, less any amounts withheld pursuant to section 4.6 hereof.
             Provided that [NAR Subco] has complied with the immediately
             preceding sentence, on and after the Liquidation Date the rights
             of each holder of CN Stapled Units representing CN Exchangeable
             Shares will be limited to receiving such holder's proportionate
             part of the total Liquidation Call Purchase Price payable by [NAR
             Subco], together with the liquidation entitlement in respect of
             the CN Voting Shares represented thereby payable by CN, upon
             presentation and surrender by the holder of certificates for CN
             Stapled Units representing the CN Exchangeable Shares and CN
             Voting Shares held by such holder and the holder shall on and
             after the Liquidation Date be considered and deemed for all
             purposes to be the holder of the Newco Common Shares to which it
             is entitled. Upon surrender to the Transfer Agent of a CN Stapled
             Unit certificate, together with such other documents and
             instruments as may be required to effect a transfer of CN Stapled
             Units under the CBCA and the by-laws of CN and such additional
             documents and instruments as the Transfer Agent may reasonably
             require, the holder of such surrendered certificate or
             certificates shall be entitled to receive in exchange therefor,
             and the Transfer Agent on behalf of [NAR Subco] shall deliver to
             such holder, certificates representing the Newco Common Shares to
             which the holder is entitled and a cheque or


<PAGE>


                                     -19-

             cheques of [NAR Subco] payable at par at any branch of the
             bankers of [NAR Subco] in payment of the remaining portion, if
             any, of the total Liquidation Call Purchase Price, less any
             amounts withheld pursuant to section 4.6 hereof. If [NAR Subco]
             does not exercise the Liquidation Call Right in the manner
             described above, on the Liquidation Date the holders of the CN

authorized but unissued shares of the Corporation, as applicable.

Section 3.2  Cheques of the Corporation payable at par at any branch of the
bankers of the Corporation shall be issued in respect of any cash dividends
contemplated by paragraph 3.1(a) hereof and the sending of such a cheque to
the holder of a CN Stapled Unit of which such CN Exchangeable Share forms part
shall satisfy the cash dividend represented thereby unless the cheque is not
paid on presentation. Certificates registered in the name of the registered
holder of CN Stapled Units of which the CN Exchangeable Share forms a part
shall be issued or transferred in respect of any stock dividends or
distributions of CN Rights contemplated by paragraph 3.1(b) or 3.1(c) hereof

satisfy the stock dividend or CN Rights distribution represented thereby. Such
other type and amount of property in respect of any dividends contemplated by
paragraph 3.1(d) hereof shall be issued, distributed or transferred by the
Corporation in such manner as it shall determine and the issuance,
distribution or transfer thereof by the Corporation to each holder of a CN
Stapled Unit shall satisfy the dividend represented thereby. No holder of a CN
Exchangeable Share shall be entitled to recover by action or other legal
process against the Corporation any dividend that is represented by a cheque
that has not been duly presented to the Corporation's bankers for payment or
that otherwise remains unclaimed for a period of six years from the date on
which such dividend was payable.

Section 3.3  The record date for the determination of the holders of CN Stapled
Units entitled to receive payment of, and the payment date for, any dividend
declared on the CN Exchangeable Shares under section 3.1 hereof shall be the
same dates as the record date and payment date, respectively, for the
corresponding dividend declared on the Newco Common Shares.

Section 3.4  If on any payment date for any dividends declared on the CN
Exchangeable Shares under section 3.1 hereof the dividends are not paid in
full on all of the CN Exchangeable Shares then outstanding, any such dividends
that remain unpaid shall be paid on a subsequent date or dates determined by
the Board of Directors on which the Corporation shall have sufficient moneys,
assets or property properly applicable to the payment of such dividends.


<PAGE>


                                     -7-



Section 3.5  The Board of Directors shall determine, in good faith and in its
sole discretion, economic equivalence for the purposes of paragraphs 3.1(d),
10.1 and 10.2 hereof, and each such determination shall be conclusive and
binding on the Corporation and its shareholders. In making each such
determination, the following factors may, without excluding other factors
determined by the Board of Directors to be relevant, be considered by the
Board of Directors:

         (a) the relationship between the fair market value (as determined by
             the Board of Directors in the manner above contemplated) of such
             property to be issued or distributed with respect to each
             outstanding Newco Common Share and the current market value (as
             determined by the Board of Directors in the manner above
             contemplated) of a Newco Stapled Unit; and

         (b) the general taxation consequences of the relevant event to holders
             of CN Stapled Units to the extent that such consequences may
             differ from the taxation consequences to holders of Newco Stapled
             Units as a result of differences between taxation laws of Canada
             and the United States (except for any differing consequences
             arising as a result of differing marginal taxation rates and
             without regard to the individual circumstances of holders of CN
             Stapled Units).

         For purposes of the foregoing determinations, the current market
value of any security listed and traded or quoted on a securities exchange
shall be the average of the closing trading or bid and ask prices of such
security during a period of not less than 20 consecutive trading days ending
not more than three trading days before the date of determination on the
principal securities exchange on which such securities are listed and traded
or quoted; provided, however, that if in the opinion of the Board of Directors
the public distribution or trading activity of such securities during such
period does not create a market which reflects the fair market value of such
securities, then the current market value thereof shall be determined by the
Board of Directors, in good faith and in its sole discretion, and provided
further that any such determination by the Board of Directors shall be
conclusive and binding on the Corporation and its shareholders.

Section 3.6  CN and the Transfer Agent shall be entitled to deduct and withhold
from any dividend or consideration otherwise payable to any holder of CN
Stapled Units representing CN Exchangeable Shares such amounts as CN or the
Transfer Agent is required or permitted to deduct and withhold with respect to
such payment under the ITA, the United States Internal Revenue Code of 1986 or
any provision of provincial, state, local or foreign tax law, in each case, as
amended. To the extent that amounts are so withheld, such withheld amounts
shall be treated for all purposes hereof as having been paid to the holder of
the shares in respect of


<PAGE>


                                     -8-


which such deduction and withholding was made, provided that such withheld
amounts are actually remitted to the appropriate taxing authority. To the
extent that the amount so required or permitted to be deducted or withheld
from any payment to a holder exceeds the cash portion of the consideration
otherwise payable to the holder, CN and the Transfer Agent are hereby
authorized to sell or otherwise dispose of such portion of the consideration
as is necessary to provide sufficient funds to CN or the Transfer Agent, as
the case may be, to enable it to comply with such deduction or withholding
requirement and CN or the Transfer Agent shall notify the holder thereof and
remit any unapplied balance of the net proceeds of such sale.

Section 3.7  Notwithstanding the foregoing provisions of this Article 3, where
the total number of voting shares held, beneficially owned or controlled,
directly or indirectly, by any one person holding CN Stapled Units together
with his or her associates exceeds the Maximum Individual Holdings, the
percentage of any and all dividends attributable to the CN Exchangeable Shares
comprising the CN Stapled Units resulting in such person exceeding the Maximum
Individual Holding shall be forfeited and the amount of the dividend so
forfeited shall not become payable thereafter to any person for any reason
whatsoever provided that notwithstanding any other provision of this Article
3:

         (a) the directors of CN may determine to pay a dividend to or to make
             any other distribution on CN Exchangeable Shares that would
             otherwise be prohibited hereby where the contravention of the
             Maximum Individual Holdings that gave rise to such prohibition
             was inadvertent or of a technical nature or it would otherwise be
             inequitable not to pay the dividend or make the distribution; and

         (b) where a dividend has not been paid or any other distribution has
             not been made on CN Exchangeable Shares comprising CN Stapled
             Units held by a person as a result of a directors' determination
             of a contravention of the Maximum Individual Holdings, the
             directors of CN shall declare and pay the dividend or make the
             distribution to the relevant person if they subsequently
             determine that no such contravention occurred.

                                   ARTICLE 4
                             CERTAIN RESTRICTIONS

             than stock dividends payable in CN Limited Voting Equity Shares
             or any such other shares ranking junior to the CN Exchangeable
             Shares, as the case may be;

         (b) redeem or purchase or make any capital distribution in respect of
             CN Limited Voting Equity Shares or any other shares ranking

             equally with the CN Exchangeable Shares with respect to the

         (d) Issue any CN Exchangeable Shares or any other shares of the

             Exchangeable Shares other than by way of stock dividends of CN
             Stapled Units to the holders of such CN Exchangeable Shares.

Section 4.2  Except as expressly provided in the Plan of Arrangement and in
this section 4.2, no CN Exchangeable Share shall be or shall be capable of

             (v) [NTD - other?]

Without limiting the generality of the foregoing, CN shall be entitled to
treat the registered holder of CN Stapled Units (or, subject to such Person
furnishing such information as is described in subsection 77(4) of the CBCA or
any replacement or successor provision therefor, the executor, administrator,
heir or legal representative of the heirs, of the estate of a deceased holder,
a guardian, committee, trustee, curator or tutor representing a holder who is
an infant, an incompetent person or a missing person, or a liquidator of or a
trustee in bankruptcy for a holder) as the owner exclusively entitled to vote,
to receive notices, to receive dividends or other payments in respect of and
otherwise to exercise all the rights and powers of the owner of the CN
Exchangeable Shares represented by such CN Stapled Unit. For purposes of
establishing and maintaining the share register for the outstanding CN
Exchangeable Shares, CN and its Transfer Agent shall and shall be entitled, at
all times (subject only to the Liquidation Call Right, the Exchange Right and
the Automatic Exchange Rights and except where a holder of CN Stapled Units
representing CN Exchangeable Shares has submitted a Retraction Request in
respect of CN Exchangeable Shares represented by such CN Stapled Unit
certificate) to treat each registered holder of CN Stapled Units as the
registered holder of a number of CN Exchangeable Shares equal to the number of
CN Stapled Units held by such Person. A CN Stapled Unit certificate shall be
the security certificate, and the only security certificate, that a holder of
CN Exchangeable Shares shall be entitled to receive in respect of his or her
holding of CN Exchangeable Shares pursuant to the CBCA or otherwise.

                                    ARTICLE 5
                          DISTRIBUTION ON LIQUIDATION

Section 5.1  In the event of the liquidation, dissolution or winding-up of the
Corporation or any other distribution of the assets of the Corporation among
its shareholders for the purpose of winding up its affairs, subject to the
exercise by Newco [NAR Subco] of the Liquidation Call Right, a holder of CN
Exchangeable Shares shall be entitled, subject to applicable law, to receive
from the assets of the Corporation in respect of each CN Exchangeable Share
held by such holder on the effective date (the "Liquidation Date") of such
liquidation, dissolution or winding-up, before any distribution of any part of
the assets of the Corporation among the holders of the CN Voting Shares, the
CN Limited Voting Equity Shares or any other shares ranking junior to the CN
Exchangeable Shares, an amount per share equal to the Current Market Price of
a Newco Stapled Unit on the last Business Day prior to


<PAGE>


                                     -11-

the Liquidation Date (the "Liquidation Amount"), which shall be satisfied in
full by the Corporation causing to be delivered to such holder one Newco
Common Share, together with all declared and unpaid dividends on each such CN
Exchangeable Share held by such holder on any dividend record date which
occurred prior to the Liquidation Date.

Section 5.2  On or promptly after the Liquidation Date, and subject to the
exercise by Newco [NAR Subco] of the Liquidation Call Right, the Corporation
shall cause to be delivered to the holders of the CN Exchangeable Shares the
Liquidation Amount for each such CN Exchangeable Share upon presentation and
surrender of the certificates representing the CN Stapled Units, together with
such other documents and instruments as may be required to effect a transfer
of CN Exchangeable Shares under the Canada Business Corporations Act and the
by-laws of the Corporation and such additional documents and instruments as
the Transfer Agent may reasonably require, at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of the CN Exchangeable Shares. Payment of
the total Liquidation Amount for such CN Exchangeable Shares shall be made by
delivery to each holder, at the address of the holder recorded in the
securities register of the Corporation for the CN Stapled Units or by holding
for pick-up by the holder at the registered office of the Corporation or at
any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of the CN Stapled Units, on behalf of the Corporation of
certificates representing Newco Common Shares (which shares shall be duly
issued as fully paid and non-assessable and shall be free and clear of any
lien, claim or encumbrance) and a cheque of the Corporation payable at par at
any branch of the bankers of the Corporation in respect of the remaining
portion, if any, of the total Liquidation Amount (in each case less any
amounts withheld on account of tax required to be deducted and withheld
therefrom). On and after the Liquidation Date, the holders of the CN
Exchangeable Shares shall cease to be holders of such CN Exchangeable Shares
and shall not be entitled to exercise any of the rights of holders in respect
thereof, other than the right to receive their proportionate part of the total
Liquidation Amount, unless payment of the total Liquidation Amount for such CN
Exchangeable Shares shall not be made upon presentation and surrender of share
certificates in accordance with the foregoing provisions, in which case the
rights of the holders shall remain unaffected until the total Liquidation
Amount has been paid in the manner hereinbefore provided. The Corporation
shall have the right at any time after the Liquidation Date to deposit or
cause to be deposited the total Liquidation Amount in respect of the CN
Exchangeable Shares represented by certificates that have not at the
Liquidation Date been surrendered by the holders thereof in a custodial
account with any chartered bank or trust company in Canada. Upon such deposit
being made, the rights of the holders of CN Exchangeable Shares after such
deposit shall be limited to receiving their proportionate part of the total
Liquidation Amount (in each case


<PAGE>


                                     -12-

less any amounts withheld on account of tax required to be deducted and
withheld therefrom) for such CN Exchangeable Shares so deposited, against
presentation and surrender of the said certificates held by them,
respectively, in accordance with the foregoing provisions. Upon such payment
or deposit of the total Liquidation Amount, the holders of the CN Exchangeable
Shares shall thereafter be considered and deemed for all purposes to be
holders of the Newco Common Shares delivered to them or the custodian on their
behalf.

Section 5.3  After the Corporation has satisfied its obligations to pay the
holders of the CN Exchangeable Shares the Liquidation Amount per CN
Exchangeable Share pursuant to section [5.1] of these share provisions, such
holders shall not be entitled to share in any further distribution of the
assets of the Corporation.

                                    ARTICLE 6
                  RETRACTION OF EXCHANGEABLE SHARES BY HOLDER

Section 6.1  A holder of CN Exchangeable Shares shall be entitled at any time,
subject to the exercise by Newco [NAR Subco] of the Retraction Call Right and
otherwise upon compliance with the provisions of this Article 6, to require
the Corporation to redeem any or all of the CN Exchangeable Shares registered
in the name of such holder for an amount per share equal to the Current Market
Price of a Newco Stapled Unit on the last Business Day prior to the Retraction
Date (the "Retraction Price"), which shall be satisfied in full by the
Corporation causing to be issued to such holder one Newco Common Share for
each CN Exchangeable Share presented and surrendered by the holder, together
with, on the payment date therefor, the full amount of all declared and unpaid
dividends on any such CN Exchangeable Share held by such holder on any
dividend record date which occurred prior to the Retraction Date. To effect
such redemption, the holder shall present and surrender at the registered
office of the Corporation or at any office of the Transfer Agent as may be
specified by the Corporation by notice to the holders of CN Stapled Units the
certificate or certificates representing the CN Stapled Units in respect of
which the holder desires to have the Corporation redeem the CN Exchangeable
Shares forming part thereof, together with such other documents and
instruments as may be required to effect a transfer of CN Stapled Units under
the Canada Business Corporations Act and the by-laws of the Corporation and
such additional documents and instruments as the Transfer Agent may reasonably
require, and together with a duly executed statement (the "Retraction
Request") in the form of Schedule A hereto or in such other form as may be
acceptable to the Corporation:

         (a) specifying that the holder desires to have all or any number
             specified therein of the CN Exchangeable Shares represented by
             such CN


<PAGE>


                                     -13-

             Stapled Unit certificate or certificates (the "Retracted Shares")
             redeemed by the Corporation;

         (b) stating the Business Day on which the holder desires to have the
             Corporation redeem the Retracted Shares (the "Retraction Date"),
             provided that the Retraction Date shall be not less than 10
             Business Days nor more than 15 Business Days after the date on
             which the Retraction Request is received by the Corporation and
             further provided that, in the event that no such Business Day is
             specified by the holder in the Retraction Request, the Retraction
             Date shall be deemed to be the 15th Business Day after the date
             on which the Retraction Request is received by the Corporation;
             and

         (c) acknowledging the overriding right (the "Retraction Call Right") of
             Newco [NAR Subco] to purchase all but not less than all the
             Retracted Shares directly from the holder and that the Retraction
             Request shall be deemed to be a revocable offer by the holder to
             sell the Retracted Shares to Newco [NAR Subco] in accordance with
             the Retraction Call Right on the terms and conditions set out in
             section 6.3 below.

Section 6.2 Subject to the exercise by Newco [NAR Subco] of the Retraction
Call Right, upon receipt by the Corporation or the Transfer Agent in the
manner specified in section 6.1 hereof of a CN Stapled Unit certificate or
certificates representing the number of CN Exchangeable Shares which the
holder desires to have the Corporation redeem, together with a Retraction
Request, and provided that the Retraction Request is not revoked by the holder
in the manner specified in section 6.7, the Corporation shall redeem the
Retracted Shares effective at the close of business on the Retraction Date and
shall cause to be delivered to such holder the total Retraction Price with
respect to such shares, provided that all declared and unpaid dividends for
which the record date has occurred prior to the Retraction Date shall be paid
on the payment date for such dividends. If only a part of the CN Exchangeable
Shares represented by any CN Stapled Unit certificate is redeemed (or
purchased by Newco [NAR Subco] pursuant to the Retraction Call Right), a new
certificate for the balance of such CN Stapled Units shall be issued to the
holder at the expense of the Corporation.

Section 6.3  Upon receipt by the Corporation of a Retraction Request, the
Corporation shall immediately notify Newco [and NAR Subco] thereof. In order
to exercise the Retraction Call Right, Newco [NAR Subco] must notify the
Corporation of its determination to do so (the "Newco [NAR Subco] Call
Notice") within five Business Days of notification to Newco [NAR Subco] by the
Corporation of the receipt by the Corporation of the Retraction Request. If
Newco [NAR Subco] does not so notify the Corporation within such five Business
Day period, the Corporation


<PAGE>


                                     -14-

will notify the holder as soon as possible thereafter that Newco [NAR Subco]
will not exercise the Retraction Call Right. If Newco [NAR Subco] delivers the
Newco [NAR Subco] Call Notice within such five Business Day period, and
provided that the Retraction Request is not revoked by the holder in the
manner specified in section 6.7, the Retraction Request shall thereupon be
considered only to be an offer by the holder to sell the Retracted Shares to
Newco [NAR Subco] in accordance with the Retraction Call Right. In such event,
the Corporation shall not redeem the Retracted Shares and Newco [NAR Subco]
shall purchase from such holder and such holder shall sell to Newco [NAR
Subco] on the Retraction Date the Retracted Shares for a purchase price (the
"Purchase Price") per share equal to the Retraction Price per share, plus, on
the designated payment date therefor, to the extent not paid by the
Corporation on the designated payment date therefor, an additional amount
equivalent to the full amount of all declared and unpaid dividends on those
Retracted Shares held by such holder on any dividend record date which
occurred prior to the Retraction Date (the "Dividend Amount"). For the
purposes of completing a purchase pursuant to the Retraction Call Right,
Newco, [NAR Subco] and the Corporation shall jointly cause to be deposited
with the Transfer Agent, on or before the Retraction Date, certificates
representing the requisite number of Newco Stapled Units and a cheque or
cheques of Newco [NAR Subco] payable at par at any branch of the bankers of
Newco [NAR Subco] representing the aggregate Dividend Amount, less any amounts
withheld on account of tax required to be deducted and withheld therefrom.
Provided that Newco [and NAR Subco] have complied with the immediately
preceding sentence, the closing of the purchase and sale of the Retracted
Shares pursuant to the Retraction Call Right shall be deemed to have occurred
as at the close of business on the Retraction Date and, for greater certainty,
no redemption by the Corporation of such Retracted Shares shall take place on
the Retraction Date. In the event that Newco [NAR Subco] does not deliver a
Newco [NAR Subco] Call Notice within such five Business Day period, and
provided that the Retraction Request is not revoked by the holder in the
manner specified in section 6.7, the Corporation shall redeem the Retracted
Shares on the Retraction Date and in the manner otherwise contemplated in this
Article 6.

Section 6.4  The Corporation, Newco [or NAR Subco], as applicable, shall
deliver or cause the Transfer Agent to deliver to the relevant holder, at the
address of the holder recorded in the securities register of the Corporation
for the CN Stapled Units comprising such CN Exchangeable Shares or at the
address specified in the holder's Retraction Request or by holding for pick-up
by the holder at the registered office of the Corporation or at any office of
the Transfer Agent as may be specified by the Corporation by notice to the
holders of CN Stapled Units, certificates representing the requisite number of
Newco Stapled Units (the Newco Common Shares included in which shares shall be
duly issued as fully paid and non-assessable and shall be free and clear of
any lien, claim or encumbrance) registered in the name of the holder or in
such other name as the holder may


<PAGE>


                                     -15-

request, and, if applicable and on or before the payment date therefor, a
cheque payable at par at any branch of the bankers of the Corporation or Newco
[NAR Subco], as applicable, representing the aggregate Dividend Amount in
payment of the total Retraction Price or the total Purchase Price, as the case
may be, in each case, less any amounts withheld on account of tax required to
be deducted and withheld therefrom, and such delivery of such certificates and
cheques on behalf of the Corporation or by Newco [NAR Subco], as the case may
be, or by the Transfer Agent shall be deemed to be payment of and shall
satisfy and discharge all liability for the total Retraction Price or total
Purchase Price, as the case may be, to the extent that the same is represented
by such share certificates and cheques (plus any tax deducted and withheld
therefrom and remitted to the proper tax authority).

Section 6.5  On and after the close of business on the Retraction Date, the
holder of the Retracted Shares shall cease to be a holder of such Retracted
Shares and shall not be entitled to exercise any of the rights of a holder in
respect thereof, other than the right to receive his proportionate part of the
total Retraction Price or total Purchase Price, as the case may be, unless
upon presentation and surrender of certificates in accordance with the
foregoing provisions, payment of the total Retraction Price or the total
Purchase Price, as the case may be, shall not be made as provided in section
6.4, in which case the rights of such holder shall remain unaffected until the
total Retraction Price or the total Purchase Price, as the case may be, has
been paid in the manner hereinbefore provided. On and after the close of
business on the Retraction Date, provided that presentation and surrender of
certificates and payment of the total Retraction Price or the total Purchase
Price, as the case may be, has been made in accordance with the foregoing
provisions, the holder of the Retracted Shares so redeemed by the Corporation
or purchased by Newco [NAR Subco] shall thereafter be considered and deemed
for all purposes to be a holder of the Newco Common Shares represented by the
Newco Stapled Unit certificates delivered to such holder.

Section 6.6  Notwithstanding any other provision of this Article 6, the
Corporation shall not be obligated to redeem Retracted Shares specified by a
holder in a Retraction Request to the extent that such redemption of Retracted
Shares would be contrary to solvency requirements or other provisions of
applicable law. If the Corporation believes that on any Retraction Date it
would not be permitted by any of such provisions to redeem the Retracted
Shares tendered for redemption on such date, and provided that Newco [NAR
Subco] shall not have exercised the Retraction Call Right with respect to the
Retracted Shares, the Corporation shall only be obligated to redeem Retracted
Shares specified by a holder in a Retraction Request to the extent of the
maximum number that may be so redeemed (rounded down to a whole number of
shares) as would not be contrary to such provisions and shall notify the
holder at least two Business Days prior to the Retraction Date as to the
number of Retracted Shares which will not be redeemed by the Corporation. In


<PAGE>


                                     -16-


any case in which the redemption by the Corporation of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law,
the Corporation shall redeem Retracted Shares in accordance with section 6.2
of these share provisions on a pro rata basis and shall issue to each holder
of Retracted Shares a new CN Stapled Unit certificate, at the expense of the
Corporation, representing the Retracted Shares not redeemed by the Corporation
pursuant to section 6.2 hereof together with a corresponding number of CN
Voting Shares. Provided that the Retraction Request is not revoked by the
holder in the manner specified in section 6.7, the holder of any such
Retracted Shares not redeemed by the Corporation pursuant to section 6.2 of
these share provisions as a result of solvency requirements or other
provisions of applicable law shall be deemed by giving the Retraction Request
to have instructed the Trustee to require Newco [NAR Subco] to purchase such
Retracted Shares from such holder on the Retraction Date or as soon as
practicable thereafter on payment by Newco [NAR Subco] to such holder of the
Purchase Price for each such Retracted Share, all as more specifically
provided in the Voting and Exchange Trust Agreement.

Section 6.7  A holder of Retracted Shares may, by notice in writing given by
the holder to the Corporation before the close of business on the Business Day
immediately preceding the Retraction Date, withdraw its Retraction Request, in
which event such Retraction Request shall be null and void and, for greater
certainty, the revocable offer constituted by the Retraction Request to sell
the Retracted Shares to Newco [NAR Subco] shall be deemed to have been
revoked.

                                    ARTICLE 7
                           PURCHASE FOR CANCELLATION

Section 7.1  Subject to applicable law and the articles of the Corporation, the
Corporation may at any time and from time to time purchase for cancellation
all or any part of the outstanding CN Exchangeable Shares together with a
corresponding number of CN Voting Shares at any price by tender to all the
holders of record of CN Exchangeable Shares and CN Voting Shares represented
by CN Stapled Units then outstanding or through the facilities of any stock
exchange on which the CN Exchangeable Shares and CN Voting Shares represented
by CN Stapled Units are listed or quoted at any price per share together with
an amount equal to all declared and unpaid dividends thereon for which the
record date has occurred prior to the date of purchase. If in response to an
invitation for tenders under the provisions of this section 7.1, more CN
Exchangeable Shares and CN Voting Shares represented by CN Stapled Units are
tendered at a price or prices acceptable to the Corporation than the
Corporation is prepared to purchase, the CN Exchangeable Shares and CN Voting
Shares represented by CN Stapled Units to be purchased by the Corporation
shall be purchased as nearly as may be pro rata according to the number of
shares


<PAGE>


                                     -17-

tendered by each holder who submits a tender to the Corporation, provided that
when CN Exchangeable Shares and CN Voting Shares represented by CN Stapled
Units are tendered at different prices, the pro rating shall be effected
(disregarding fractions) only with respect to the CN Exchangeable Shares and
CN Voting Shares represented by CN Stapled Units tendered at the price at
which more CN Exchangeable Shares and CN Voting Shares represented by CN
Stapled Units were tendered than the Corporation is prepared to purchase after
the Corporation has purchased all the CN Exchangeable Shares and CN Voting
Shares represented by CN Stapled Units tendered at lower prices. If part only
of the CN Exchangeable Shares and CN Voting Shares represented by CN Stapled
Units represented by any certificate shall be purchased, a new certificate for
CN Stapled Units representing the balance of such CN Exchangeable Shares and
CN Voting Shares not purchased shall be issued at the expense of the
Corporation.

                                   ARTICLE 8
                                 VOTING RIGHTS

Section 8.1  Except as required by applicable law and by Article 10 hereof, the
holders of the CN Exchangeable Shares, as such, shall not be entitled to
receive notice of or to attend any meeting of the shareholders of the
Corporation or to vote at any such meeting.

                                   ARTICLE 9
                            AMENDMENT AND APPROVAL

Section 9.1 The rights, privileges, restrictions and conditions attaching to
the CN Exchangeable Shares may be added to, changed or removed but only with
the approval of the holders of the CN Exchangeable Shares given as hereinafter
specified.

Section 9.2  In addition to any other approval required by the CBCA or other
applicable law, any approval given by the holders of the CN Exchangeable
Shares to add to, change or remove any right, privilege, restriction or
condition attaching to the CN Exchangeable Shares or any other matter
requiring the approval or consent of the holders of the CN Exchangeable Shares
shall be deemed to have been sufficiently given if it shall have been given in
accordance with applicable law subject to a minimum requirement that such
approval be evidenced by resolution passed by not less than two-thirds of the
votes cast on such resolution (excluding any votes cast on such resolution in
respect of CN Exchangeable Shares held by or on behalf of CN, Newco, [NAR
Subco] or any of their respective Affiliates) at a meeting of holders of CN
Exchangeable Shares duly called and held in accordance with the By-laws of the
Corporation.

          RECIPROCAL CHANGES, ETC. IN RESPECT OF Newco COMMON SHARES

Co-operation Agreement provides, in part, that Newco will not without the
prior approval of the Corporation and the prior approval of the holders of the

             exchangeable for or convertible into or carrying rights to
             acquire Newco Common Shares) to the holders of all or
             substantially all of the then outstanding Newco Common Shares by
             way of stock dividend or other distribution, other than an issue
             of Newco Common Shares to holders of Newco Common Shares who
             exercise an option to receive dividends in Newco Common Shares
             represented by Newco Stapled Units in lieu of receiving cash

         (c) issue or distribute to the holders of all or substantially all of

or distribution of CN Exchangeable Shares and CN Voting Shares comprising CN
Stapled Units or CN Rights complying with the requirements of paragraphs
3.1(b) or (c), as applicable, is made or, in the case of paragraph 10.1(c),
the economic equivalent on a per share basis of such other shares or
securities, rights, options, warrants, evidences of indebtedness or other
assets is issued or distributed simultaneously to holders of the CN
Exchangeable Shares or unless, in the case of a stock dividend payable in
Newco Common Shares represented by Newco Stapled Units, in lieu of such a
stock dividend the Corporation effects a corresponding and

         (b) reduce, combine, consolidate or change the then outstanding Newco
             Common Shares into a lesser number of Newco Common Shares; or

         (c) reclassify or otherwise change the Newco Common Shares or effect an
             amalgamation, merger, reorganization or other transaction
             affecting the Newco Common Shares,

unless the same in the case of paragraph [(a) and (b)] above or, in the case
of paragraph [(c)] above, the same or an economically equivalent change shall
simultaneously be made to, or in the rights of the holders of, the CN
Exchangeable Shares and the CN Voting Shares. The Co-operation Agreement
further provides, in part, that the aforesaid provisions of the Co-operation
Agreement shall not be changed without the approval of the holders of the CN

2.       Constraints on Issue and Transfer

         The Corporation shall not:

         (a) accept any subscription for its voting shares;

         (b) issue any of its voting shares; or

         (c) register or otherwise recognize the transfer of any of its voting
             shares;

if, as a result of such subscription, issue, transfer, purchase or
acquisition, voting shares to which are attached more than fifteen percent

controlled, directly or indirectly, by any one person together with the
associates of such person.

3.       Constraints on Ownership Rights

         No person, together with his or her associates, shall hold,
beneficially own or control, directly or indirectly, voting shares to which

Subsections 4.1 and 4.2, the Corporation shall refuse to recognize all

4.       Limitation on Voting Rights and dividend forfeiture

4.1      Where the total number of voting shares held, beneficially owned or

associates exceeds the Maximum Individual Holdings, no person shall, in person
or by proxy, exercise the voting rights attached to the voting shares held,
beneficially owned or controlled, directly or indirectly, by such person or
his or her associates. If the Corporation redeems, purchases for cancellation
or otherwise acquires voting shares, and the result of such action is that any
person and the associates of that


<PAGE>


                                     -3-


person who, prior to such action, were not in contravention of the Maximum
Individual Holdings are, after such action, in contravention, then,
notwithstanding any other provision of this Exhibit "I", the sole consequence
of such action to that person and the associates of that person, in respect of
the voting shares of that person and of the associates of that person held,
beneficially owned or controlled at the time of such action, shall be that the
number of votes attached to those voting shares shall be reduced to a number
that is the largest whole number of votes that may be attached to the voting
shares which that person and the associates of that person could hold,
beneficially own or control from time to time in accordance with the Maximum
Individual Holdings.

4.2      Where the total number of voting shares held, beneficially owned or
controlled, directly or indirectly, by any one person together with his or her
associates exceeds the Maximum Individual Holdings, the percentage of any and
all dividends attributable to the percentage of voting shares exceeding the
Maximum Individual Holding shall be forfeited including any cumulative
dividend and the amount of dividend so forfeited shall not become payable
thereafter to any person for any reason whatsoever provided that
notwithstanding any other provision of this Exhibit "I":

         (a) the directors of the Corporation may determine to pay a
             dividend or to make any other distribution on voting shares
             that would otherwise be prohibited by any other provision of
             this Exhibit "I" where the contravention of the Maximum
             Individual Holdings that gave rise to the prohibition was
             inadvertent or of a technical nature or it would otherwise
             be inequitable not to pay the dividend or make the
             distribution; and

         (b) where a dividend has not been paid or any other distribution
             has not been made on voting shares of a person as a result
             of a directors' determination of a contravention of the
             Maximum Individual Holdings, the directors of the
             Corporation shall declare and pay the dividend or make the
             distribution to the relevant person if they subsequently
             determine that no such contravention occurred.

4.3      Notwithstanding any other provision of this Exhibit "I", a
contravention of the Maximum Individual Holdings shall have no consequences
except those that are expressly provided for in this Exhibit "I". For greater
certainty but without limiting the generally of the foregoing:

         (a) no transfer, issue or ownership of, and no title to, voting shares;

         (b) no resolution of shareholders; and


<PAGE>


                                     -4-




         (c) no act of the Corporation, including any transfer of property to or
             by the Corporation;

shall be invalid or otherwise affected by any contravention of the Maximum
Individual Holdings.

5.       Sale of Constrained Shares

         Without limiting any of the provisions of this Exhibit "I" the
Corporation (but subject to Subsection 4.1) may, for the purposes of enforcing
any constraint imposed pursuant to Section 2 above, sell, as if it were the
owner thereof, any voting shares that are owned, or that the directors
determine may be owned, by any person or persons, contrary to such constraint.
Such sale shall be conducted in accordance with the procedures set forth in
Part VI of the CBCA and Part VII of the CBCA Regulations with necessary
modifications, as if such provisions applied to the sale of such voting shares
and the net proceeds of sale thereof shall be remitted to the person or
persons entitled thereto in accordance with such provisions.

6.       Associates

6.1      For the purposes of this Exhibit "I", a person is an associate of
another person if:

         (a) one is a corporation of which the other is an officer or director;

         (b) one is a corporation that is controlled by the other or by a

                  will be, to the declarant's knowledge, held in the right of,
                  for the use or benefit of or under the control of, any other
                  person of which, but for this paragraph, the declarant would
                  be an associate, and

             (ii) the declarant is not acting and will not act in concert with
                  any such other person with respect to their interests,
                  direct or indirect, in the Corporation,

                  exercised, to elect a majority of the directors of the body
                  corporate; and

         (b) a partnership or unincorporated organization is controlled
             by a person if an ownership interest therein representing
             more than fifty percent (50%) of the assets of the

Section 4.3   Mailings to Shareholders.

         With respect to each Newco Meeting and Newco Consent, the Trustee will
mail or cause to be mailed (or otherwise communicate in the same manner as Newco
utilizes in communications to holders of Newco Stapled Units) to each of the
Beneficiaries named in the List referred to in section 4.6, such mailing or
communication to commence on the same day as the mailing or notice (or other
communication) with respect thereto is commenced by Newco to holders of Newco

     (a) a copy of such notice, together with any related materials to be
         provided to holders of Newco Stapled Units;

     (b) a statement that such Beneficiary is entitled to instruct the Trustee
         as to the exercise of the Beneficiary Votes with respect to such Newco
         Meeting or Newco Consent or, pursuant to section 4.7, to attend such
         Newco Meeting and to exercise personally the Beneficiary Votes thereat;

     (c) a statement as to the manner in which such instructions may be given to
         the Trustee, including an express indication that instructions may be
         given to the Trustee to give:

         (i) a proxy to such Beneficiary or his designee to exercise personally
             the Beneficiary Votes; or

         (ii) a proxy to a designated agent or other representative of the
             management of Newco to exercise such Beneficiary Votes;

     (d) a statement that if no such instructions are received from the
         Beneficiary, the Beneficiary Votes to which such Beneficiary is
         entitled will not be exercised;

     (e) a form of direction whereby the Beneficiary may so direct and instruct
         the Trustee as contemplated herein; and

     (f) a statement of the time and date by which such instructions must be

         case of a Newco Meeting shall not be earlier than the close of business
         on the [second Business Day] prior to such meeting, and of the method
         for revoking or amending such instructions.

         For the purpose of determining Beneficiary Votes to which a Beneficiary
is entitled in respect of any Newco Meeting or Newco Consent, the number of CN
Exchangeable Shares represented by CN Stapled Units owned of record by the
Beneficiary shall be determined at the close of business on the record date
<PAGE>


established by Newco or by applicable law for purposes of determining
shareholders entitled to vote at such Newco Meeting. Newco will notify the
Trustee of any decision of the Board of Directors of Newco with respect to the
calling of any Newco Meeting and shall provide all necessary information and
materials to the Trustee in each case promptly and in any event in sufficient
time to enable the Trustee to perform its obligations contemplated by this
section 4.3.

Section 4.4   Copies of Shareholder Information.

         Newco will deliver to the Trustee copies of all proxy materials
(including notices of Newco Meetings but excluding proxies to vote Newco Common
Shares or CN Voting Shares), information statements, reports (including without
limitation, all interim and annual financial statements) and other written
communications that, in each case, are to be distributed from time to time to
holders of Newco Stapled Units in sufficient quantities and in sufficient time
so as to enable the Trustee to send those materials to each Beneficiary at the
same time as such materials are first sent to holders of Newco Stapled Units.
The Trustee will mail or otherwise send to each Beneficiary, at the expense of
Newco, copies of all such materials (and all materials specifically directed to
the Beneficiaries or to the Trustee for the benefit of the Beneficiaries by
Newco) received by the Trustee from Newco contemporaneously with the sending of
such materials to holders of Newco Stapled Units. The Trustee will also make
available for inspection by any Beneficiary at the Trustee's principal corporate
trust office in the City of Montreal all proxy materials, information
statements, reports and other written communications that are:

         (a) received by the Trustee as the registered holder of the Special
             Voting Share and made available by Newco generally to the holders
             of Newco Stapled Units; or

             the benefit of the Beneficiaries by Newco.

Section 4.5   Other Materials.

         As soon as reasonably practicable after receipt by Newco or holders of
Newco Stapled Units (if such receipt is known by Newco) of any material sent or
given by or on behalf of a third party to holders of Newco Stapled Units
generally, including without limitation, dissident proxy and information
circulars (and related information and material) and tender and exchange offer
circulars (and related information and material), Newco shall use its reasonable
efforts to obtain and deliver to the Trustee copies thereof in sufficient
quantities so as to enable the Trustee to forward such material (unless the same
has been provided directly to Beneficiaries by such third party) to each
Beneficiary as soon as possible thereafter. Immediately upon receipt thereof,
the Trustee will mail or otherwise send to each Beneficiary, at the expense of
Newco, copies of all such materials received by the

<PAGE>


Trustee from Newco. The Trustee will also make available for inspection by any
Beneficiary at the Trustee's principal corporate trust office in the City of
Montreal copies of all such materials.

Section 4.6   List of Persons Entitled to Vote.

         CN shall, (a) prior to each annual, general and special Newco Meeting
or the seeking of any Newco Consent and (b) forthwith upon each request made at
any time by the Trustee in writing, prepare or cause to be prepared a list (the
"List") of the names and addresses of the Beneficiaries arranged in alphabetical
order and showing the number of CN Exchangeable Shares represented by CN Stapled
Units held of record by each such Beneficiary, in each case at the close of
business on the date specified by the Trustee in such request or, in the case of
a List prepared in connection with a Newco Meeting or a Newco Consent, at the
close of business on the record date established by Newco or pursuant to
applicable law for determining the holders of Newco Stapled Units entitled to
receive notice of and/or to vote the Newco Common Share component thereof at
such Newco Meeting or to give consent in connection with such Newco Consent.
Each such List shall be delivered to the Trustee promptly after receipt by CN of
such request or the record date for such meeting or seeking of consent, as the
case may be. Newco agrees to give CN notice (with a copy to the Trustee) of the
calling of any Newco Meeting or the seeking of any Newco Consent, together with
the record dates therefor, sufficiently prior to the date of the calling of such
meeting or seeking of such consent so as to enable CN to perform its obligations
under this section 4.6.

Section 4.7   Entitlement to Direct Votes.

         Any Beneficiary named in a List prepared in connection with any Newco
Meeting or Newco Consent will be entitled (a) to instruct the Trustee in the
manner described in section 4.3 with respect to the exercise of the Beneficiary
Votes to which such Beneficiary is entitled or (b) to attend such meeting and
personally exercise thereat, as the proxy of the Trustee, the Beneficiary Votes
to which such Beneficiary is entitled.

Section 4.8   Voting by Trustee, and Attendance of Trustee Representative at
Meeting.

         (a) In connection with each Newco Meeting and Newco Consent, the

             with the instructions received from a Beneficiary pursuant to
             section 4.3, the Beneficiary Votes as to which such Beneficiary is
             entitled to direct the vote (or any lesser number thereof as may be
             set forth in the instructions); provided, however, that such
             written instructions are received by the Trustee from the
             Beneficiary prior to the time and date fixed by the Trustee for
             receipt of such instruction in the notice given by the Trustee to
             the Beneficiary pursuant to section 4.3.


<PAGE>


         (b) The Trustee shall cause a representative who is empowered by it to
             sign and deliver, on behalf of the Trustee, proxies for Voting
             Rights to attend each Newco Meeting. Upon submission by a
             Beneficiary (or its designee) of identification satisfactory to the
             Trustee's representative, and at the Beneficiary's request, such
             representative shall sign and deliver to such Beneficiary (or its
             designee) a proxy to exercise personally the Beneficiary Votes as
             to which such Beneficiary is otherwise entitled hereunder to direct
             the vote, if such Beneficiary either (i) has not previously given
             the Trustee instructions pursuant to section 4.3 in respect of such
             meeting or (ii) submits to such representative written revocation
             of any such previous instructions. At such meeting, the Beneficiary
             exercising such Beneficiary Votes shall have the same rights as the
             Trustee to speak at the meeting in favour of any matter, question,
             proposal or proposition, to vote by way of ballot at the meeting in
             respect of any matter, question, proposal or proposition, and to
             vote at such meeting by way of a show of hands in respect of any
             matter, question or proposition.

Section 4.9   Distribution of Written Materials.

         Any written materials distributed by the Trustee pursuant to this trust
agreement shall be sent by mail (or otherwise communicated in the same manner as
Newco utilizes in communications to holders of Newco Stapled Units) to each
Beneficiary at its address as shown on the books of CN. CN shall provide or
cause to be provided to the Trustee for this purpose, on a timely basis and
without charge or other expense:

         (a) a current List; and

         (b) upon the request of the Trustee, mailing labels to enable the
             Trustee to carry out its duties under this trust agreement.

Section 4.10  Termination of Voting Rights.

         All of the rights of a Beneficiary with respect to the Beneficiary
Votes exercisable in respect of the CN Exchangeable Shares represented by CN
Stapled Units held by such Beneficiary, including the right to instruct the
Trustee as to the voting of or to vote personally such Beneficiary Votes, shall
be deemed to be surrendered by the Beneficiary to Newco, and such Beneficiary
Votes and the Voting Rights represented thereby shall cease immediately upon the
delivery by such holder to the Trustee of the certificates for the CN Stapled
Units representing such CN Exchangeable Shares in connection with the exercise
by the Beneficiary of the Exchange Right or the occurrence of the automatic
exchange of CN Exchangeable Shares for Newco Common Shares, as specified in
Article 5 (unless, in either case, [NAR Subco] or Newco, as applicable, shall
not have caused to be issued the



<PAGE>


requisite Newco Common Shares issuable in exchange therefor and caused to be
delivered Newco Stapled Units representing same (together with the CN Voting
Shares retained by such holder) to the Trustee for delivery to the
Beneficiaries), or upon the redemption of CN Exchangeable Shares pursuant to
Article 6 of the CN Exchangeable Share Provisions, or upon the effective date
of the liquidation, dissolution or winding-up of CN pursuant to Article 5 of
the CN Exchangeable Share Provisions, or upon the purchase of CN Exchangeable
Shares from the holder thereof by [NAR Subco] pursuant to the exercise by [NAR
Subco] of the Retraction Call Right or the Liquidation Call Right.

                      EXCHANGE RIGHT AND AUTOMATIC EXCHANGE

Section 5.1   Grant and Ownership of the Exchange Right.

         Newco hereby grants to the Trustee as trustee for and on behalf of, and
for the use and benefit of, the Beneficiaries the right (the "Exchange Right"),
upon the occurrence and during the continuance of an Insolvency Event, to
require Newco to purchase from each or any Beneficiary all or any part of the CN
Exchangeable Shares held by the Beneficiary and the Automatic Exchange Rights,
all in accordance with the provisions of this trust agreement. Newco hereby
acknowledges receipt from the Trustee as trustee for and on behalf of the
Beneficiaries of good and valuable consideration (and the adequacy thereof) for
the grant of the Exchange Right and the Automatic Exchange Rights by Newco to
the Trustee. During the term of the Trust and subject to the terms and
conditions of this trust agreement, the Trustee shall possess and be vested with
full legal ownership of the Exchange Right and the Automatic Exchange Rights and
shall be entitled to exercise all of the rights and powers of an owner with
respect to the Exchange Right and the Automatic Exchange Rights, provided that
the Trustee shall:

         (a) hold the Exchange Right and the Automatic Exchange Rights and the
             legal title thereto as trustee solely for the use and benefit of
             the Beneficiaries in accordance with the provisions of this trust
             agreement; and

         (b) except as specifically authorized by this trust agreement, have no
             power or authority to exercise or otherwise deal in or with the
             Exchange Right or the Automatic Exchange Rights, and the Trustee
             shall not exercise any such rights for any purpose other than the
             purposes for which the Trust is created pursuant to this trust
             agreement.


<PAGE>


Section 5.2   Legended Unit Certificates.

         CN will cause each certificate representing CN Stapled Units to bear an
appropriate legend notifying the Beneficiaries of:

         (a) their right to instruct the Trustee with respect to the exercise of
             the Exchange Right in respect of the CN Exchangeable Shares forming
             part of the CN Stapled Units held by a Beneficiary; and

         (b) the Automatic Exchange Rights.

Section 5.3   General Exercise of Exchange Right.

         The Exchange Right shall be and remain vested in and exercisable by the
Trustee. Subject to section 7.15, the Trustee shall exercise the Exchange Right
only on the basis of instructions received pursuant to this Article 5 from
Beneficiaries entitled to instruct the Trustee as to the exercise thereof. To
the extent that no instructions are received from a Beneficiary with respect to
the Exchange Right, the Trustee shall not exercise or permit the exercise of the
Exchange Right.

Section 5.4   Purchase Price.

         The purchase price payable by Newco for each CN Exchangeable Share to
be purchased by Newco under the Exchange Right shall be an amount per share
equal to (a) the Current Market Price of a Newco Stapled Unit on the last
Business Day prior to the day of closing of the purchase and sale of such CN
Exchangeable Share under the Exchange Right, which shall be satisfied in full by
Newco causing to be issued to such holder one Newco Common Share, plus (b) to
the extent not paid by CN, an additional amount equivalent to the full amount of
all declared and unpaid dividends on each such CN Exchangeable Share held by
such holder on any dividend record date which occurred prior to the closing of
the purchase and sale. The purchase price for each such CN Exchangeable Share so
purchased may be satisfied only by Newco issuing to the relevant Beneficiary,
one Newco Common Share and delivering or causing to be delivered to the relevant
Beneficiary a Newco Stapled Unit certificate representing same (as well as the
CN Voting Shares retained by such Beneficiary) and on the applicable payment
date a cheque for the balance, if any, of the purchase price without interest
(but less any amounts withheld pursuant to section 5.13).

Section 5.5   Exercise Instructions.

         Subject to the terms and conditions herein set forth, a Beneficiary
shall be entitled, upon the occurrence and during the continuance of an
Insolvency Event, to instruct the Trustee to exercise the Exchange Right with
respect to all or any part of the CN Exchangeable Shares represented by CN
Stapled Units registered in the name of such Beneficiary on the books of CN. To
cause the exercise of the Exchange Right by the Trustee, the Beneficiary shall
deliver to the Trustee, in person or by


<PAGE>


certified or registered mail, at its principal corporate trust office in
Montreal, Quebec or at such other places in Canada as the Trustee may from time
to time designate by written notice to the Beneficiaries, the CN Stapled Unit
certificates representing the CN Exchangeable Shares which such Beneficiary
desires Newco to purchase, duly endorsed in blank for transfer, and accompanied
by such other documents and instruments as may be required to effect a transfer
of CN Exchangeable Shares under the Canada Business Corporations Act and the
by-laws of CN and such additional documents and instruments as the Trustee may
reasonably require together with (a) a duly completed form of notice of
exercise of the Exchange Right, contained on the reverse of or attached to the
CN Stapled Unit certificates, stating (i) that the Beneficiary thereby
instructs the Trustee to exercise the Exchange Right so as to require Newco to
purchase from the Beneficiary the number of CN Exchangeable Shares specified
therein, (ii) that such Beneficiary has good title to and owns all such CN
Exchangeable Shares to be acquired by Newco free and clear of all liens, claims
and encumbrances, (iii) the names in which the certificates representing Newco
Stapled Units representing the Newco Common Shares issuable in connection with
the exercise of the Exchange Right are to be issued and (iv) the names and
addresses of the persons to whom such new certificates should be delivered and
(b) payment (or evidence satisfactory to the Trustee, CN and Newco of payment)
of the taxes (if any) payable as contemplated by section 5.8 of this trust
agreement. If only a part of the CN Exchangeable Shares represented by any CN
Stapled Unit certificate or certificates delivered to the Trustee are to be
purchased by Newco under the Exchange Right, a new certificate for the balance
of such CN Stapled Units shall be issued to the holder at the expense of CN.

Section 5.6   Delivery of Newco Stapled Units; Effect of Exercise.

         Promptly after receipt of the CN Stapled Unit certificates representing
the CN Exchangeable Shares which the Beneficiary desires Newco to purchase under
the Exchange Right, together with such documents and instruments of transfer and
a duly completed form of notice of exercise of the Exchange Right (and payment
of taxes, if any, payable as contemplated by section 5.8 or evidence thereof),
duly endorsed for transfer, the Trustee shall notify Newco and CN of its receipt
of the same, which notice to Newco and CN shall constitute exercise of the
Exchange Right by the Trustee on behalf of the holder of such CN Exchangeable
Shares, and Newco shall promptly thereafter issue to the relevant Beneficiary
(or to such other persons, if any, properly designated by such Beneficiary) the
number of Newco Common Shares issuable in connection with the exercise of the
Exchange Right, and shall deliver or cause to be delivered to the relevant
Beneficiary a Newco Stapled Unit certificate representing same (as well as the
CN Voting Shares retained by such Beneficiary) and on the applicable payment
date cheques for the balance, if any, of the total purchase price therefor
without interest (but less any amounts withheld pursuant to section 5.13);
provided, however, that no such delivery shall be made unless and until the
Beneficiary requesting the same shall have paid (or provided


<PAGE>


evidence satisfactory to the Trustee, CN and Newco of the payment of) the taxes
(if any) payable as contemplated by section 5.8 of this trust agreement.
Immediately upon the giving of notice by the Trustee to Newco and CN of the
exercise of the Exchange Right as provided in this section 5.6, the closing of
the transaction of purchase and sale contemplated by the Exchange Right shall
be deemed to have occurred and the holder of the CN Stapled Units representing
the CN Exchangeable Shares so sold shall be deemed to have transferred to Newco
all of such holder's right, title and interest in and to such CN Exchangeable
Shares and the related interest in the Trust Estate and shall cease to be a
holder of such CN Exchangeable Shares and shall not be entitled to exercise any
of the rights of a holder in respect thereof, other than the right to receive
his or her proportionate part of the total purchase price therefor, unless the
requisite number of Newco Common Shares is not allotted and issued by Newco and
Newco Stapled Units representing same (as well as the CN Voting Shares retained
by such Beneficiary) shall not have been delivered for distribution by the
Trustee to such Beneficiary within five Business Days of the date of the giving
of such notice by the Trustee, in which case the rights of the Beneficiary
shall remain unaffected until such Newco Common Shares are so allotted and
issued and the Newco Stapled Units representing same have been delivered by
Newco. Upon delivery by Newco to the Trustee of certificates for Newco Stapled
Units representing such Newco Common Shares, the Trustee shall deliver such
Newco Stapled Units to such Beneficiary (or to such other persons, if any,
properly designated by such Beneficiary). Concurrently with such Beneficiary
ceasing to be a holder of CN Exchangeable Shares, the Beneficiary shall be
considered and deemed for all purposes to be the holder of the Newco Common
Shares delivered to it pursuant to the Exchange Right.

Section 5.7   Exercise of Exchange Right Subsequent to Retraction.

         In the event that a Beneficiary has exercised its right under Article 6
of the CN Exchangeable Share Provisions to require CN to redeem any or all of
the CN Exchangeable Shares held by the Beneficiary (the "Retracted Shares") and
is notified by CN pursuant to section 6.6 of the CN Exchangeable Share
Provisions that CN will not be permitted as a result of solvency requirements of
applicable law to redeem all such Retracted Shares, and provided that [NAR
Subco] shall not have exercised the Retraction Call Right with respect to the
Retracted Shares and that the Beneficiary has not revoked the retraction request
delivered by the Beneficiary to CN pursuant to section 6.1 of the CN
Exchangeable Share Provisions, the retraction request will constitute and will
be deemed to constitute notice from the Beneficiary to the Trustee instructing
the Trustee to exercise the Exchange Right with respect to those Retracted
Shares that CN is unable to redeem. In any such event, CN hereby agrees with the
Trustee and in favour of the Beneficiary promptly to forward or cause to be
forwarded to the Trustee all relevant materials delivered by the Beneficiary to
CN or to the transfer agent of the CN Stapled Units (including without
limitation, a copy of the retraction request delivered pursuant to section 6.1
of the CN Exchangeable

<PAGE>


Share Provisions) in connection with such proposed redemption of the Retracted
Shares and the Trustee will thereupon exercise the Exchange Right with respect
to the Retracted Shares that CN is not permitted to redeem and will require
Newco to purchase such shares in accordance with the provisions of this Article
5.

Section 5.8   Stamp or Other Transfer Taxes.

         Upon any sale of CN Exchangeable Shares to Newco pursuant to the
Exchange Right or the Automatic Exchange Rights, the certificate or certificates
for the Newco Stapled Units representing the Newco Common Shares issued in
payment therefor to be delivered in connection with the payment of the total
purchase price therefor shall be issued in the name of the Beneficiary or in
such names as such Beneficiary may otherwise direct in writing without charge to
such Beneficiary; provided, however, that such Beneficiary (a) shall pay (and
none of Newco, CN or the Trustee shall be required to pay) any documentary,
stamp, transfer or other taxes that may be payable in respect of any transfer
involved in the issuance or delivery of such shares to a person other than such
Beneficiary or (b) shall have evidenced to the satisfaction of the Trustee,
Newco and CN that such taxes, if any, have been paid.

Section 5.9   Notice of Insolvency Event.

         As soon as practicable following the occurrence of an Insolvency Event
or any event that with the giving of notice or the passage of time or both would
be an Insolvency Event, CN and Newco shall give written notice thereof to the
Trustee. As soon as practicable following the receipt of notice from CN and
Newco of the occurrence of an Insolvency Event, or upon the Trustee becoming
aware of an Insolvency Event, the Trustee will mail to each Beneficiary, at the
expense of Newco, a notice of such Insolvency Event, which notice shall contain
a brief statement of the rights of the Beneficiaries with respect to the
Exchange Right.

Section 5.10  Qualification of Newco Common Shares.

         Newco covenants that if any Newco Common Shares to be issued pursuant
to the Exchange Right or the Automatic Exchange Rights require registration or
qualification with or approval of or the filing of any document, including any
prospectus or similar document, or the taking of any proceeding with or the
obtaining of any order, ruling or consent from any governmental or regulatory
authority under any Canadian or United States federal, provincial or state law
or regulation or pursuant to the rules and regulations of any regulatory
authority or the fulfilment of any other Canadian or United States federal,
provincial or state legal requirement before such shares may be issued or the
Newco Stapled Units of which they form part may be delivered by Newco to the
initial holder thereof or in order that such shares and the Newco Stapled Units
representing same may be freely traded thereafter (other than any restrictions
of general application on transfer, including without limitation by reason of a
holder being a "control person"


<PAGE>


for purposes of Canadian provincial securities law or an "affiliate" of Newco
for purposes of United States federal or state securities law), Newco will in
good faith expeditiously take all such actions and do all such things as are
necessary or desirable to cause such Newco Common Shares and/or Newco Stapled
Units, as applicable, to be and remain duly registered, qualified or approved.
Newco will in good faith expeditiously take all such actions and do all such
things as are reasonably necessary or desirable to cause all Newco Common
Shares represented by Newco Stapled Units to be issued and delivered pursuant
to the Exchange Right or the Automatic Exchange Rights to be listed, quoted or
posted for trading on all stock exchanges and quotation systems on which such
shares have been listed by Newco and remain listed and are quoted or posted for
trading at such time.

Section 5.11  Newco Common Shares.

         Newco hereby represents, warrants and covenants that the Newco Common
Shares issuable as described herein and in the CN Exchangeable Share Provisions
will be duly authorized and validly issued as fully paid and non-assessable and
shall be free and clear of any lien, claim or encumbrance.

Section 5.12  Automatic Exchange on Liquidation of Newco.

         (a) Newco will give the Trustee notice of each of the following events
             at the time set forth below:

                  Newco to institute voluntary liquidation, dissolution or
                  winding-up proceedings with respect to Newco or to effect any
                  other distribution of assets of Newco among its shareholders
                  for the purpose of winding up its affairs, at least 60 days
                  prior to the proposed effective date of such liquidation,
                  dissolution, winding-up or other distribution; and

             (ii) as soon as practicable following the earlier of (A) receipt by
                  Newco of notice of, and (B) Newco otherwise becoming aware of,
                  any threatened or instituted claim, suit, petition or other
                  proceedings with respect to the involuntary liquidation,
                  dissolution or winding-up of Newco or to effect any other
                  distribution of assets of Newco among its shareholders for the
                  purpose of winding up its affairs, in each case where Newco
                  has failed to contest in good faith any such proceeding
                  commenced in respect of Newco within 30 days of becoming aware
                  thereof.

         (b) As soon as practicable following receipt by the Trustee from Newco
             of notice of any event (a "Liquidation Event") contemplated by

             pro rata basis with the holders of Newco Common Shares in the
             distribution of assets of Newco in connection with a Liquidation
             Event, on the fifth Business Day prior to the effective date (the
             "Liquidation Event Effective Date ") of a Liquidation Event all of
             the then outstanding CN Exchangeable Shares shall be automatically
             exchanged for Newco Common Shares. To effect such automatic
             exchange, Newco shall purchase on the fifth Business Day prior to
             the Liquidation Event Effective Date each CN Exchangeable Share
             then outstanding and held by Beneficiaries, and each Beneficiary
             shall sell the CN Exchangeable Shares held by it at such time, for
             a purchase price per share equal to (a) the Current Market Price of
             a Newco Stapled Unit on the fifth Business Day prior to the
             Liquidation Event Effective Date, which shall be satisfied in full
             by Newco issuing to the Beneficiary one Newco Common Share, and (b)
             to the extent not paid by CN, an additional amount equivalent to
             the full amount of all declared and unpaid dividends on each such
             CN Exchangeable Share held by such holder on any dividend record
             date which occurred prior to the date of the exchange.

         (d) On the fifth Business Day prior to the Liquidation Event Effective
             Date, the closing of the transaction of purchase and sale
             contemplated by the automatic exchange of CN Exchangeable Shares
             for Newco Common Shares shall be deemed to have occurred, and each
             Beneficiary shall be deemed to have transferred to Newco all of the
             Beneficiary's right, title and interest in and to such
             Beneficiary's CN Exchangeable Shares and the related interest in
             the Trust Estate and shall cease to be a holder of such CN
             Exchangeable Shares and Newco shall issue to the Beneficiary the
             Newco Common Shares issuable upon the automatic exchange of CN
             Exchangeable Shares for Newco Common Shares and on the applicable
             payment date shall deliver to the Trustee for delivery to the
             Beneficiary a cheque for the balance, if any, of the total purchase
             price for such CN Exchangeable Shares without interest but less any
             amounts withheld pursuant to section 5.13. Concurrently with such
             Beneficiary ceasing to be a holder of CN Exchangeable Shares, the
             Beneficiary shall be considered and deemed for all purposes to be
             the holder of the Newco Common Shares issued pursuant to the
             automatic exchange of CN Exchangeable Shares for Newco Common
             Shares and the certificates held by the Beneficiary previously
             representing the CN Stapled Units containing the CN Exchangeable
             Shares exchanged by


<PAGE>


             the Beneficiary with Newco pursuant to such automatic exchange
             shall thereafter be deemed to represent Newco Stapled Units
             containing the Newco Common Shares issued to the Beneficiary by
             Newco pursuant to such automatic exchange. Upon the request of a
             Beneficiary and the surrender by the Beneficiary of CN Stapled
             Unit certificates deemed to represent Newco Stapled Units
             representing the Newco Common Shares so acquired upon the
             exercise of such Automatic Exchange Right (as well as the CN
             Voting Share retained by such Beneficiary), duly endorsed in
             blank and accompanied by such instruments of transfer as Newco
             may reasonably require, Newco shall deliver or cause to be
             delivered to the Beneficiary certificates representing the Newco
             Stapled Units of which the Beneficiary is the holder.

Section 5.13  Withholding Rights.

         Newco, CN and the Trustee shall be entitled to deduct and withhold from
any consideration otherwise payable under this trust agreement to any holder of
CN Exchangeable Shares or Newco Common Shares such amounts as Newco, CN or the
Trustee is required or permitted to deduct and withhold with respect to such
payment under the Income Tax Act (Canada), the United States Internal Revenue
Code of 1986 or any provision of provincial, state, local or foreign tax law, in
each case as amended or succeeded. To the extent that amounts are so withheld,
such withheld amounts shall be treated for all purposes as having been paid to
the holder of the shares in respect of which such deduction and withholding was
made, provided that such withheld amounts are actually remitted to the
appropriate taxing authority. To the extent that the amount so required or
permitted to be deducted or withheld from any payment to a holder exceeds the
cash portion of the consideration otherwise payable to the holder, Newco, CN and
the Trustee are hereby authorized to sell or otherwise dispose of such portion
of the consideration as is necessary to provide sufficient funds to Newco, CN or
the Trustee, as the case may be, to enable it to comply with such deduction or
withholding requirement and Newco, CN or the Trustee shall notify the holder
thereof and remit to such holder any unapplied balance of the net proceeds of
such sale. CN and Newco represent and warrant that, based upon facts currently
known to each of them, CN has no current intention, as at the date of this
Agreement, to deduct or withhold, and Newco has no current intention, as at the
date of this Agreement to cause CN to deduct or withhold, from any dividend paid
to holders of CN Stapled Units representing CN Exchangeable Shares any amounts
under the United States Internal Revenue Code of 1986.

             trustee for and on behalf of the Beneficiaries in accordance with
             the provisions of this trust agreement;

         (b) granting proxies and distributing materials to Beneficiaries as

             Beneficiaries in accordance with the provisions of this trust
             agreement;

         (e) exercising the Exchange Right and enforcing the benefit of the

             requisite documents and distributing to such Beneficiaries Newco
             Stapled Units and cheques, if any, to which such Beneficiaries are

             Automatic Exchange Rights, as the case may be;

         (f) holding title to the Trust Estate;

         (h) taking action on its own initiative or at the direction of a
             Beneficiary or Beneficiaries to enforce the obligations of Newco
             and CN under this trust agreement; and

         (i) taking such other actions and doing such other things as are
             specifically provided in this trust agreement.

         In the exercise of such rights, powers, duties and authorities the

powers, duties and authority not in conflict with any of the provisions of this
trust agreement as the Trustee, acting in good faith and in the reasonable
exercise of its discretion, may deem necessary, appropriate or desirable to
effect the purpose of the Trust. Any exercise of such discretionary rights,
powers, duties and authorities by the Trustee shall be final, conclusive and
binding upon all persons.

         The Trustee in exercising its rights, powers, duties and authorities

interests of the Beneficiaries and shall exercise the care, diligence and skill
that a reasonably prudent trustee would exercise in comparable circumstances.

Section 7.2   No Conflict of Interest.

         The Trustee represents to Newco and CN that at the date of execution
and delivery of this trust agreement there exists no material conflict of
interest in the role of the Trustee as a fiduciary hereunder and the role of the
Trustee in any other capacity. The Trustee shall, within 90 days after it
becomes aware that such material conflict of interest exists, either eliminate
such material conflict of interest or resign in the manner and with the effect
specified in Article 10. If, notwithstanding the foregoing provisions of this
section 7.2, the Trustee has such a material conflict of interest, the validity
and enforceability of this trust agreement shall not be affected in any manner
whatsoever by reason only of the existence of such material conflict of
interest. If the Trustee contravenes the foregoing provisions of this section
7.2, any interested party may apply to the [Quebec Superior Court - NTD: unless

             registrars and transfer agents, and with any such subsequent
             registrar or transfer agent, of the CN Exchangeable Shares, the CN
             Voting Shares, the CN Stapled Units, the Newco Common Shares and
             the Newco Stapled Units; and

         (b) requisition, from time to time, (i) from any such registrar or
             transfer agent any information readily available from the records
             maintained by it which the Trustee may reasonably require for the
             discharge of its duties and responsibilities under this trust
             agreement and (ii) from the transfer agent of the Newco Common
             Shares and the Newco Stapled Units, and any subsequent transfer

             exercise from time to time of the Exchange Right and pursuant to
             the Automatic Exchange Rights.

         Newco and CN irrevocably authorize their respective registrars and
transfer agents to comply with all such requests. Newco covenants that it will
supply its transfer agent with duly executed unit certificates for the purpose
of completing the exercise from time to time of the Exchange Right and the
Automatic Exchange Rights.

             Newco of Newco Common Shares in connection with the Exchange Right,
             during the calendar year ended on such December 31; and

         (c) any action taken by the Trustee in the performance of its duties
             under this trust agreement which it had not previously reported and

             Estate.

Section 7.5   Income Tax Returns and Reports.

institute such action, suit or proceeding and furnished the Trustee with the

failed to act within a reasonable time thereafter. In such case, but not
otherwise, the Beneficiary shall be entitled to take proceedings in any court of

Shares, including any disagreement between the heirs, representatives,
successors or assigns succeeding to all or any part of the interest of any
Beneficiary in any CN Stapled Units or CN Exchangeable Shares, resulting in
conflicting claims or demands being made in connection with such interest, then
the Trustee shall be entitled, at its sole discretion, to refuse to recognize or
to comply with any such claims or demands. In so refusing, the Trustee may elect

             been furnished with an executed copy of such agreement certified to
             be in full force and effect.

         If the Trustee elects to recognize any claim or comply with any demand

claimant to furnish such surety bond or other security satisfactory to the
Trustee as it shall deem appropriate to fully indemnify it as between all
conflicting claims or demands.

Section 9.1   Indemnification of the Trustee.

         Newco and CN jointly and severally agree to indemnify and hold harmless
the Trustee and each of its directors, officers and agents appointed and acting
in accordance with this trust agreement (collectively, the "Indemnified
Parties") against all claims, losses, damages, reasonable costs, penalties,
fines and reasonable expenses (including reasonable expenses of the Trustee's
legal counsel) which, without fraud, negligence, recklessness, willful
misconduct or bad faith on the part of such Indemnified Party, may be paid,
incurred or suffered by the Indemnified Party by reason or as a result of the

Parties shall have received any such written assertion of a claim or shall have
been served with a summons or other first legal process giving information as to
the nature and basis of the claim. Subject to (ii) below, Newco and CN shall be
entitled to participate at their own expense in the defence and, if Newco and CN
so elect at any time after receipt of such notice, either of them may assume the
defence of any suit brought to enforce any such claim. The Trustee shall have
the right to employ separate counsel in any such suit and participate in the
defence thereof but the fees and expenses of such counsel shall be at the
expense of the Trustee unless: (i) the employment of such counsel has been
authorized by Newco or CN; or (ii) the named parties to any such suit include
both the Trustee and Newco or CN and the Trustee shall have been advised by
counsel acceptable to Newco or CN that there may be one or more legal defences
available to the Trustee that are different from or in addition to those
available to Newco or CN and that, in the judgment of such counsel, would
present a conflict of interest were a joint representation to be undertaken (in
which case Newco and CN shall not have the right to assume the defence of such
suit on behalf of the Trustee but shall be liable to pay the reasonable fees and
expenses of counsel for the Trustee).

Section 9.2   Limitation of Liability.

         The Trustee shall not be held liable for any loss which may occur by
reason of depreciation of the value of any part of the Trust Estate or any loss
incurred on any investment of funds pursuant to this trust agreement, except to
the extent that such loss is attributable to the fraud, negligence,
recklessness, willful misconduct or bad faith on the part of the Trustee.

                                CHANGE OF TRUSTEE

Section 10.1  Resignation.

         The Trustee, or any trustee hereafter appointed, may at any time resign
by giving written notice of such resignation to Newco and CN specifying the date
on which it desires to resign, provided that such notice shall not be given less
than one month before such desired resignation date unless Newco and CN
otherwise agree and provided further that such resignation shall not take effect
until the date of the appointment of a successor trustee and the acceptance of
such appointment by the successor trustee. Upon receiving such notice of
resignation, Newco and CN shall promptly appoint a successor trustee by written
instrument in duplicate, one copy of which shall be delivered to the resigning
trustee and one copy to the successor trustee.

Section 10.2  Removal.

         The Trustee, or any trustee hereafter appointed, may (provided a
successor trustee is appointed) be removed at any time on not less than 30 days'
prior notice by written instrument executed by Newco and CN, in duplicate, one
copy of which shall be delivered to the trustee so removed and one copy to the
successor trustee.

Section 10.3  Successor Trustee.

         Any successor trustee appointed as provided under this trust agreement
shall execute, acknowledge and deliver to Newco and CN and to its predecessor
trustee an instrument accepting such appointment. Thereupon the resignation or
removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations of its predecessor under this
trust agreement, with the like effect as if originally named as trustee in this
trust agreement. However, on the written request of Newco and CN or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of this trust agreement, execute and
deliver an instrument transferring to such successor trustee all the rights and
powers of the trustee so ceasing to act. Upon the request of any such successor
trustee, Newco, CN and such predecessor trustee shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers.

Section 10.4  Notice of Successor Trustee.

         Upon acceptance of appointment by a successor trustee as provided
herein, Newco and CN shall cause to be mailed notice of the succession of such
trustee hereunder to each Beneficiary specified in a List. If Newco or CN shall
fail to cause such notice to be mailed within 10 days after acceptance of
appointment by the

<PAGE>


successor trustee, the successor trustee shall cause such notice to be mailed
at the expense of Newco and CN.

                                Newco SUCCESSORS

Section 11.1  Certain Requirements in Respect of Combination, etc.

         Newco shall not consummate any transaction (whether by way of
reconstruction, reorganization, consolidation, merger, transfer, sale, lease or
otherwise) whereby all or substantially all of its undertaking, property and
assets would become the property of any other person or, in the case of a
merger, of the continuing corporation resulting therefrom unless, but may do so
if, in addition to any other requirements required to be satisfied pursuant to
the terms of the Co-operation Agreement or the CN Exchangeable Share Provisions:

         (a) such other person or continuing corporation (herein called the
             "Newco Successor "), by operation of law, becomes, without more,
             bound by the terms and provisions of this trust agreement or, if
             not so bound, executes, prior to or contemporaneously with the
             consummation of such transaction, a trust agreement supplemental
             hereto and such other instruments (if any) as are satisfactory to
             the Trustee, acting reasonably, and in the opinion of legal counsel
             to the Trustee are reasonably necessary or advisable to evidence
             the assumption by the Newco Successor of liability for all moneys
             payable and property deliverable hereunder and the covenant of such
             Newco Successor to pay and deliver or cause to be delivered the
             same and its agreement to observe and perform all the covenants and
             obligations of Newco under this trust agreement; and

         (b) such transaction shall, to the satisfaction of the Trustee, acting
             reasonably, and in the opinion of legal counsel to the Trustee, be
             upon such terms and conditions as substantially to preserve and not
             to impair in any material respect any of the rights, duties, powers
             and authorities of the Trustee or of the Beneficiaries hereunder.

Section 11.2  Vesting of Powers in Successor.

         Whenever the conditions of section 11.1 have been duly observed and
performed, the Trustee and, if required by section 11.1, Newco Successor and CN
shall execute and deliver the supplemental trust agreement provided for in
Article 12 and thereupon Newco Successor shall possess and from time to time may
exercise each and every right and power of Newco under this trust agreement in
the name of Newco or otherwise and any act or proceeding by any provision of
this trust agreement required to be done or performed by the Board of Directors
of Newco or


<PAGE>


any officers of Newco may be done and performed with like force and effect by
the directors or officers of such Newco Successor.

Section 11.3  Wholly-Owned Subsidiaries.

         Nothing herein shall be construed as preventing the amalgamation or
merger of any wholly-owned direct or indirect subsidiary of Newco with or into
Newco or the winding-up, liquidation or dissolution of any wholly-owned
subsidiary of Newco provided that all of the assets of such subsidiary are
transferred to Newco or another wholly-owned direct or indirect subsidiary of
Newco and any such transactions are expressly permitted by this Article 11.

purposes of:

         (a) adding to the covenants of any or all parties hereto for the
             protection of the Beneficiaries hereunder provided that the Board
             of Directors of each of CN and Newco shall be of the good faith

             or interests of the Beneficiaries;

         (b) making such amendments or modifications not inconsistent with this
             trust agreement as may be necessary or desirable with respect to
             matters or questions which, in the good faith opinion of the Board
             of Directors of each of Newco and CN and in the opinion of the
             Trustee, having in mind the best interests of the Beneficiaries it
             may be expedient to make, provided that such Boards of Directors
             and the Trustee shall be of the opinion that such amendments and
             modifications will not be prejudicial to the interests of the
             Beneficiaries; or

         (c) making such changes or corrections which, on the advice of counsel
             to Newco, CN and the Trustee, are required for the purpose of

             clerical omission or mistake or manifest error, provided that
             the Trustee and the Board of Directors of each of Newco and CN
             shall be of the opinion that such changes or corrections will
             not be prejudicial to the rights and interests of the
             Beneficiaries.

Section 12.3  Changes in Capital of Newco and CN.

         At all times after the occurrence of any event contemplated pursuant to
section 4.1, 4.2, 4.3, 4.4 and 4.5 of the Co-operation Agreement or otherwise,
as a result of which either Newco Common Shares or the CN Exchangeable Shares or
both are in any way changed, this trust agreement shall forthwith be amended and
modified as necessary in order that it shall apply with full force and effect,

             with the provisions of Article 11 and the successors of any
             successor trustee in accordance with the provisions of Article 10;

             Exchange Right or the Automatic Exchange Rights which, in the
             opinion of the Trustee, will not be prejudicial to the interests of
             the Beneficiaries or are, in the opinion of counsel to the Trustee,
             necessary or advisable in order to incorporate, reflect or comply
             with any legislation the provisions of which apply to Newco, CN,
             the Trustee or this trust agreement; and

         (c) for any other purposes not inconsistent with the provisions of this

close of business on December 31, 1999 (the "Record Date"), each Right
representing the right to purchase one one-hundredth of a Preferred Share (as
hereinafter defined), upon the terms and subject to the conditions herein set
forth, and has further authorized and directed the issuance of one Right with
respect to each Common Share that shall become outstanding between the Record
Date and the Expiration Date (as such terms are hereinafter defined).

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

         Section 1. Certain Definitions. For purposes of this Agreement, the
following terms have the meanings indicated:

         "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates and Associates (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner
(as such term is hereinafter defined) of 15% or



                                      -1-

<PAGE>


more of the Common Shares of the Company then outstanding, but shall not
include the Company, any Subsidiary (as such term is defined herein) of the
Company, any employee benefit plan of the Company or of any Subsidiary of the
Company, or any Person holding Common Shares for or pursuant to the terms of
any such plan. Notwithstanding the foregoing, no Person shall become an
"Acquiring Person" as the result of (a) an acquisition of Common Shares by the
Company which, by reducing the number of Common Shares outstanding, increases
the proportionate number of Common Shares beneficially owned by such Person to
15% or more of the Common Shares of the Company then outstanding or (b) the
acquisition by such Person of newly-issued Common Shares directly from the
Company (it being understood that a purchase from an underwriter or other
intermediary is not deemed for purposes hereof to be a purchase directly from
the Company); provided, however, that if a Person shall become the Beneficial
Owner of 15% or more of the Common Shares of the Company then outstanding by
reason of share purchases by the Company or the receipt of newly-issued Common
Shares directly from the Company and shall, after such share purchases or
direct issuance by the Company, become the Beneficial Owner of any additional
Common Shares of the Company, then such Person shall be deemed to be an
"Acquiring Person;" provided further, however, that any transferee from such
Person who becomes the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding shall nevertheless be deemed to be an "Acquiring
Person". Notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph, has become such inadvertently, and such Person divests



                                      -2-

<PAGE>


as promptly as practicable (and in any event within ten Business Days after
notification by the Company) a sufficient number of Common Shares so that such
Person would no longer be an Acquiring Person, as defined pursuant to the
foregoing provisions of this paragraph, then such Person shall not be deemed to
be an "Acquiring Person" for any purposes of this Agreement.

         "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Exchange Act, as in effect on the date of this Agreement.

         A Person shall be deemed the "Beneficial Owner" of and shall be deemed
to have "beneficial ownership" of or to "beneficially own" any securities:

          (a) which such Person or any of such Person's Affiliates or
     Associates beneficially owns, directly or indirectly;

          (b) which such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has (i) the right to acquire (whether
     such right is exercisable immediately or only after the passage of time)
     pursuant to any agreement, arrangement or understanding, whether written
     or oral (other than customary agreements with and between underwriters and
     selling group members with respect to a bona fide public offering of
     securities), or upon the exercise of conversion rights, exchange rights,
     rights (other than these Rights), warrants or options, or otherwise;
     provided, however, that a Person shall not be deemed the Beneficial Owner
     of, have "beneficial ownership" of or to beneficially own, (A) securities
     tendered pursuant to a tender or exchange offer made by or on behalf of
     such Person or any of such Person's Affiliates or Associates until such



                                      -3-

<PAGE>


     tendered securities are accepted for purchase or exchange, (B) securities
     issuable upon exercise of Rights at any time prior to the occurrence of a
     Triggering Event (as such term is hereinafter defined) or (C) securities
     issuable upon exercise of Rights from and after the occurrence of a
     Triggering Event, which Rights were acquired by such Person or any of such
     Person's Affiliates or Associates prior to the Distribution Date or
     pursuant to Section 3(a) hereof ("Original Rights") or pursuant to Section
     11(i) or Section 22 hereof in connection with an adjustment made with
     respect to Original Rights; (ii) the sole or shared right to vote or
     dispose (including any such right pursuant to any agreement, arrangement
     or understanding, whether written or oral); provided, however, that a
     Person shall not be deemed the Beneficial Owner of, or to beneficially
     own, any security if the agreement, arrangement or understanding to vote
     such security (1) arises solely from a revocable proxy or consent given to
     such Person in response to a public proxy or consent solicitation made
     pursuant to, and in accordance with, the applicable rules and regulations
     promulgated under the Exchange Act and (2) is not also then reportable on
     Schedule 13D under the Exchange Act (or any comparable or successor
     report); or (iii) "beneficial ownership" (as determined pursuant to Rule
     13d-3 (or any successor rule) of the General Rules and Regulations under
     the Exchange Act);

          (c) which are beneficially owned, directly or indirectly, by any
     other Person (or any Affiliate or Associate thereof) with which such
     Person or any of such Person's Affiliates or Associates has any agreement,
     arrangement or understanding, whether written or oral (other than
     customary agreements with and between underwriters and



                                      -4-

<PAGE>


     selling group members with respect to a bona fide public offering of
     securities) for the purpose of acquiring, holding, voting (except to the
     extent contemplated by the proviso to clause (B) of subparagraph (b) of
     this definition) or disposing of any securities of the Company; or

          (d) which are directly, indirectly or constructively owned by such
     Person or any such Person's Affiliates or Associates, within the meaning
     of Section 958 of the U.S. Internal Revenue Code of 1986, as amended.

         Notwithstanding anything in this definition of Beneficial Ownership to
the contrary, the phrase "then outstanding," when used with reference to a
Person's Beneficial Ownership of securities of the Company, shall mean the
number of such securities then issued and outstanding together with the number
of such securities not then actually issued and outstanding which such Person
would be deemed to own beneficially hereunder.

         Notwithstanding anything in this definition of Beneficial Ownership to
the contrary, for purposes of this Agreement, neither (i) any "clearing
agency," as defined in Section 3(a)(23)(A) of the Exchange Act, which is
holding securities solely in its capacity as a clearing agency, nor (ii) North
American Railways, Inc. ("Newco"), a Delaware corporation 50% owned by the
Company and 50% owned by Canadian National Railway Company ("CN"), a Canadian
corporation, shall not be deemed a "Beneficial Owner" of, or to "beneficially
own," any shares of any class of capital stock of the Company as a result of
the execution, delivery or performance of the Combination Agreement dated as of
December 18, 1999 between CN, the Company, Newco and Western Merger Sub, Inc.,
a Delaware corporation and a wholly owned subsidiary of Newco

City time, on such date; provided, however, that if such date is not a Business

         "Common Shares" when used with reference to the Company shall mean the
shares of common stock, par value $0.01 per share, of the Company (as such
shares may be constituted or designated, or as such par value may be changed,

with reference to any Person other than the Company shall mean the capital
stock (or equity interest) with the greatest voting power of such other Person
or the equity securities or other equity interest having power to control or

<PAGE>


(including any such date which is after the date of this Agreement and prior to
the issuance of the Rights; the earlier of such dates being herein referred to
as the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates for Common Shares
registered in the names of the holders thereof (which certificates shall also
be deemed to be certificates for Rights) and not by separate certificates, and
(y) the Rights will be transferable only in connection with the transfer of the
underlying Common Shares (including a transfer to the Company). The Company
shall give the Rights Agent prompt written notice of the Distribution Date. As
soon as practicable after the Distribution Date, the Company will prepare and
execute, the Rights Agent will, after receipt of written notice of the
Distribution Date from the Company, countersign, and the Company will send or
cause to be sent (and the Rights Agent will, if requested, send at the expense
of the Company) to each record holder of Common Shares as of the close of
business on the Distribution Date, at the address of such holder shown on the
records of the Company, a Right Certificate, in substantially the form of
Exhibit B hereto (a "Right Certificate"), evidencing an aggregate number of
Rights equal to one Right for each Common Share so held. As of the Distribution
Date, the Rights will be evidenced solely by such Right Certificates.

         (b) As soon as practicable after the Record Date, the Company will
send a copy of a Summary of Rights Plan, in substantially the form of Exhibit C
hereto (the "Summary of Rights Plan"), to each record holder of Common Shares
as of the close of business on the Record Date (other than any Acquiring Person
or any Associate or Affiliate of any Acquiring Person), at the address of such
holder shown on the records of the Company. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,
the Rights will



                                      -9-

<PAGE>


be evidenced by such certificates registered in the names of the holders
thereof together with the Summary of Rights Plan, and registered holders of
Common Shares shall also be the registered holders of the associated Rights.
Until the Distribution Date (or the earlier of the Redemption Date or the Final
Expiration Date), the transfer of any certificate for Common Shares outstanding
on the Record Date, with or without a copy of the Summary of Rights Plan, shall
also constitute the transfer of the Rights associated with the Common Shares
represented thereby.

         (c) Rights shall be issued in respect of all Common Shares which are
issued (whether originally issued or delivered from the Company's treasury)
after the Record Date but prior to the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date. Certificates representing such
Common Shares shall also be deemed to be certificates for Rights. Certificates
representing both Common Shares and Rights in accordance with this Section 3
which are executed and delivered (whether the Common Shares represented thereby
are originally issued, delivered from the Company's treasury or are presented
for transfer) by the Company (including, without limitation, certificates
representing reacquired Common Shares referred to in the last sentence of this
paragraph (c)) after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them a legend
substantially equivalent to the following:

         This certificate also evidences and entitles the holder hereof to
         certain rights as set forth in the Rights Agreement between BURLINGTON
         NORTHERN SANTA FE CORPORATION (the "Company") and ___________________,
         dated as of December 18, 1999 (the "Rights Agreement"), the terms of
         which are hereby incorporated herein by reference and a copy of which
         is on file at the principal offices of the Company. Under certain
         circumstances, as set forth in the Rights



                                      -10-

<PAGE>


         Agreement, such Rights will be evidenced by separate certificates and
         will no longer be evidenced by this certificate. The Company will mail
         to the holder of this certificate a copy of the Rights Agreement, as
         in effect on the date of mailing, without charge promptly after
         receipt of a written request therefor. Under certain circumstances set
         forth in the Rights Agreement, Rights issued to, or held by, any
         Person who is, was or becomes an Acquiring Person or an Affiliate or
         Associate thereof (as such terms are defined in the Rights Agreement),
         whether currently held by or on behalf of such Person or by any
         subsequent holder, shall become null and void.

Until the Distribution Date, the Rights associated with the Common Shares shall
be evidenced by the certificates representing the associated Common Shares
alone, and the transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby.
In the event that the Company purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, any Rights associated with such
Common Shares shall be deemed cancelled and retired so that the Company shall
not be entitled to exercise any Rights associated with the Common Shares which
are no longer outstanding.

         Section 4.  Form of Right Certificates.

         (a) The Right Certificates (and the forms of election to purchase
Preferred Shares and of assignment to be printed on the reverse thereof) shall
each be substantially in the form set forth in Exhibit B hereto and may have
such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the
Rights may from time to time be listed, or to conform to usage. The Right
Certificates shall be in a machine printable format and in a form



                                      -11-

<PAGE>


reasonably satisfactory to the Rights Agent. Subject to the provisions of
Sections 11, 13, 22 and 24 hereof, the Right Certificates shall entitle the
holders thereof to purchase such number of one one-hundredths of a Preferred
Share as shall be set forth therein at the price per one one-hundredth of a
Preferred Share set forth therein (the "Purchase Price"), but the amount and
type of securities purchasable upon the exercise of each Right and the Purchase
Price thereof shall be subject to adjustment as provided herein.

         (b) Any Right Certificate issued pursuant to Section 3(a) or Section
22 hereof that represents Rights beneficially owned by: (i) an Acquiring Person
or any Associate or Affiliate of an Acquiring Person, (ii) a transferee of an
Acquiring Person (or such Associate or Affiliate) who becomes a transferee
after the Acquiring Person becomes an Acquiring Person, or (iii) a transferee
of an Acquiring Person (or such Associate or Affiliate) who becomes a
transferee prior to or concurrently with the Acquiring Person becoming such and
receives such Rights pursuant to either (A) a transfer (whether or not for
consideration) from the Acquiring Person to holders of equity interests in such
Acquiring Person or to any Person with whom the Acquiring Person has any
continuing agreement, arrangement or understanding, whether written or oral,
regarding the transferred Rights or (B) a transfer which the Board of Directors
otherwise concludes in good faith is part of a plan, arrangement or
understanding, whether written or oral, which has as a primary purpose or
effect avoidance of Section 7(e) hereof, and any Right Certificate issued
pursuant to Section 6 or Section 11 hereof upon transfer, exchange, replacement
or adjustment of any other Right Certificate referred to in this sentence,
shall contain (to the extent feasible and otherwise reasonably identifiable as
such) the following legend:




                                      -12-

<PAGE>


         The Rights represented by this Right Certificate are or were
         beneficially owned by a Person who was or became an Acquiring Person
         or an Affiliate or Associate of an Acquiring Person (as such terms are
         defined in the Rights Agreement). Accordingly, this Right Certificate
         and the Rights represented hereby may become void in the circumstances
         specified in Section 7(e) of such Agreement.

The Company shall instruct the Rights Agent in writing of the Rights which
should be so legended and shall supply the Rights Agent with such legended
Right Certificates. The provisions of Section 7(e) shall apply whether or not
any Right Certificate actually contains the foregoing legend.

         Section 5. Countersignature and Registration. The Right Certificates
shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, any Vice Chairman, its President, any of its Vice
Presidents, or its Treasurer, either manually or by facsimile signature, shall
have affixed thereto the Company's seal or a facsimile thereof, and shall be
attested by the Secretary or an Assistant Secretary of the Company, either
manually or by facsimile signature. The Right Certificates shall be manually
countersigned by the Rights Agent and shall not be valid for any purpose unless
countersigned. In case any officer of the Company who shall have signed any of
the Right Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as
though the person who signed such Right Certificates had not ceased to be such
officer of the Company; and any Right Certificate may be signed on behalf of
the Company by any person who, at the actual date of the execution of such
Right Certificate, shall be a proper officer of the Company to sign such Right



                                      -13-

<PAGE>


Certificate, although at the date of the execution of this Agreement any such
person was not such an officer.

         Following the Distribution Date, the Rights Agent will keep or cause
to be kept, at its office designated for such purpose, books for registration
and transfer of the Right Certificates issued hereunder. Such books shall show
the names and addresses of the respective holders of the Right Certificates,
the number of Rights evidenced on its face by each of the Right Certificates
and the date of each of the Right Certificates.

         Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.

         (a) Subject to the provisions of Sections 4(b), 7(e), 14 and 24
hereof, at any time after the close of business on the Distribution Date, and
at or prior to the close of business on the earlier of the Redemption Date or
the Final Expiration Date, any Right Certificate or Right Certificates may be
transferred, split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a like number
of Preferred Shares (or, following a Triggering Event, Common Shares, other
securities or property, as the case may be) as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Right
Certificate or Right Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or exchanged at the office
of the Rights Agent designated for such purpose. Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect



                                      -14-

<PAGE>


to the transfer of any such surrendered Right Certificate until the registered
holder shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Right Certificate accompanied by such
documents as the Rights Agent may deem appropriate and the Company shall have
been provided with such additional evidence of the identity of the Beneficial
Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the
Company shall reasonably request. Thereupon the Rights Agent shall, subject to
Sections 4 and 7 hereof, countersign and deliver to the person entitled thereto
a Right Certificate or Right Certificates, as the case may be, as so requested.
The Company may require payment by the holders of Rights Certificates of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Right
Certificates.

         (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation
of a Right Certificate, and, in case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to them, and, at the Company's
request, reimbursement to the Company and the Rights Agent of all reasonable
expenses incidental thereto, and upon surrender to the Rights Agent and
cancellation of the Right Certificate if mutilated, the Company will make and
deliver a new Right Certificate of like tenor to the Rights Agent for
countersignature and delivery to the registered holder in lieu of the Right
Certificate so lost, stolen, destroyed or mutilated.

         Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) Subject to Section 7(e) hereof, the registered holder of any Right
Certificate may exercise the Rights



                                      -15-

<PAGE>


evidenced thereby (except as otherwise provided herein) in whole or in part at
any time after the Distribution Date upon surrender of the Right Certificate,
with the form of election to purchase on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent designated for
such purpose, together with payment of the Purchase Price with respect to each
surrendered Right for the total number of Preferred Shares (or other securities
or property, as the case may be) as to which the Rights are exercised, at or
prior to the earliest of (i) the close of business on December 18, 2009 (the
"Final Expiration Date"), (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date"), (iii) the time
immediately prior to the effective time of the merger of Merger Sub with and
into the Company in accordance with Delaware law and pursuant to the
Combination Agreement (the "Merger Date") (the earliest of (i), (ii) or (iii)
being herein referred to as the "Expiration Date") or (iv) the time at which
such Rights are exchanged as provided in Section 24 hereof.

         (b) The Purchase Price for each one one-hundredth of a Preferred Share
pursuant to the exercise of a Right shall initially be $100.00, shall be
subject to adjustment from time to time as provided in Sections 11 and 13
hereof and shall be payable in lawful money of the United States of America in
accordance with paragraph (c) below.

         (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase and the certificate on the
reverse side of the Right Certificate duly executed, accompanied by such
documents as the Rights Agent may deem appropriate, payment of the Purchase
Price for the shares (or other securities or property, as the case may be) to
be purchased and an amount equal to any applicable transfer tax required to be
paid by the holder of



                                      -16-

<PAGE>


such Right Certificate in accordance with Section 9 hereof by certified check,
cashier's check or money order payable to the order of the Company, the Rights
Agent shall thereupon promptly (i) (A) requisition from any transfer agent of
the Preferred Shares (or make available, if the Rights Agent is the transfer
agent of the Preferred Shares) certificates for the number of Preferred Shares
to be purchased and the Company hereby irrevocably authorizes its transfer
agent to comply with all such requests, or (B) if the Company shall have
elected to deposit the Preferred Shares issuable upon exercise of the Rights
with a depositary agent, requisition from the depositary agent depositary
receipts representing such number of one one-hundredths of a Preferred Share as
are to be purchased (in which case certificates for the Preferred Shares
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company will direct the depositary agent to comply
with such request, (ii) when appropriate, requisition from the Company the
amount of cash to be paid in lieu of issuance of fractional shares in
accordance with Section 14 hereof, (iii) after receipt of such certificates or
depositary receipts, cause the same to be delivered to or upon the order of the
registered holder of such Right Certificate, registered in such name or names
as may be designated by such holder and (iv) when appropriate, after receipt,
deliver such cash to or upon the order of the registered holder of such Right
Certificate. In the event that the Company is obligated to issue other
securities (including Common Shares) of the Company, pay cash and/or distribute
other property pursuant to Section 11(a) hereof, the Company will make all
arrangements necessary so that such other securities, cash and/or property are
available for distribution by the Rights Agent, if and when appropriate.

         (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be
issued by the Rights Agent and delivered to the registered holder of such Right
Certificate or to his duly authorized assigns, subject to the provisions of
Section 14 hereof.

         (e) Notwithstanding anything in this Agreement to the contrary, from
and after the occurrence of a Triggering Event, any Rights beneficially owned
by (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person,
(ii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes an
Acquiring Person, or (iii) a transferee of an Acquiring Person (or such
Associate or Affiliate) who becomes a transferee prior to or concurrently with
the Acquiring Person becoming an Acquiring Person and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding, whether written or oral, regarding the
transferred Rights or (B) a transfer which the Board of Directors otherwise
concludes in good faith is part of a plan, arrangement or understanding
(whether written or oral) which has as a primary purpose or effect the
avoidance of this Section 7(e), shall become null and void without any further
action, and any holder of such Rights shall thereupon have no rights whatsoever
with respect to such Rights, whether under any provision of this Agreement or
otherwise, from and after the occurrence of a Triggering Event. The Company
shall use all reasonable efforts to insure that the provisions of



                                      -18-

<PAGE>


this Section 7(e) hereof are complied with, but shall have no liability to any
holder of Rights for the inability to make any determinations with respect to
an Acquiring Person or its Affiliates, Associates or transferees hereunder.

         (f) Notwithstanding anything in this Agreement to the contrary,
neither the Rights Agent nor the Company shall be obligated to undertake any
action with respect to a registered holder upon the occurrence of any purported
exercise as set forth in this Section 7 unless the certificate contained in the
form of election to purchase set forth on the reverse side of the Right
Certificate surrendered for such exercise shall have been completed and signed
by the registered holder thereof and the Company shall have been provided with
such additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) or Affiliates or Associates thereof as the Company shall
reasonably request.

         (g) The Company covenants and agrees that it will cause to be reserved
and kept available out of its authorized and unissued Preferred Shares (and,
following the occurrence of a Triggering Event, Common Shares and/or other
securities) or any Preferred Shares (and, following the occurrence of a
Triggering Event, Common Shares and/or other securities) held in its treasury,
the number of Preferred Shares (and, following the occurrence of a Triggering
Event, Common Shares and/or other securities) that will be sufficient to permit
the exercise in full of all outstanding Rights.

         (h) Notwithstanding any statement to the contrary contained in this
Agreement or in any Right Certificate, if the Distribution Date or the Shares
Acquisition Date shall occur prior to the Record Date, the provisions of this
Agreement, including (without limitation) Sections 3 and



                                      -19-

<PAGE>


11(a)(ii), shall be applicable to the Rights upon their issuance to the same
extent such provisions would have been applicable if the Record Date were the
date of this Agreement.

         Section 8. Cancellation and Destruction of Right Certificates. All
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Rights Agreement. The Company shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall
deliver all cancelled Right Certificates to the Company, or shall, at the
written request of the Company, cause such cancelled Right Certificates to be
destroyed, and in such case cause a certificate of destruction to be delivered
to the Company.

         Section 9. Availability of Preferred Shares. The Company covenants and
agrees that it will take all such action as may be necessary to ensure that all
Preferred Shares (and, following the occurrence of a Triggering Event, Common
Shares and/or other securities) delivered upon exercise of Rights shall, at the
time of delivery of the certificates for such Preferred Shares (and, following
the occurrence of a Triggering Event, Common Shares and/or other securities),
subject to payment of the Purchase Price, be duly and validly authorized and
issued and fully paid and nonassessable shares.



                                      -20-

<PAGE>


         The Company further covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of the Right Certificates or of
any Preferred Shares (or Common Shares and/or other securities, as the case may
be) upon the exercise of Rights. The Company shall not, however, be required to
pay any transfer tax which may be payable in respect of any transfer or
delivery of Right Certificates to a person other than, or the issuance or
delivery of certificates or depositary receipts for the Preferred Shares (or
Common Shares and/or other securities, as the case may be) in a name other than
that of, the registered holder of the Right Certificate evidencing Rights
surrendered for exercise or to issue or to deliver any certificates or
depositary receipts for Preferred Shares (or Common Shares and/or other
securities, as the case may be) upon the exercise of any Rights until any such
tax shall have been paid (any such tax being payable by the holder of such
Right Certificate at the time of surrender) or until it has been established to
the Company's reasonable satisfaction that no such tax is due.

         Section 10. Preferred Shares Record Date. Each person (other than the
Company) in whose name any certificate for Preferred Shares (or Common Shares
and/or other securities, as the case may be) is issued upon the exercise of
Rights shall for all purposes be deemed to have become the holder of record of
the shares or securities represented thereby on, and such certificate shall be
dated, the date upon which the Right Certificate evidencing such Rights was
duly surrendered and payment of the Purchase Price (and any applicable transfer
taxes or other governmental charges) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Shares
(or Common Shares and/or other securities, as



                                      -21-

<PAGE>


the case may be) transfer books of the Company are closed, such person shall be
deemed to have become the record holder of such shares or securities on, and
such certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares (or Common Shares and/or other securities, as the case may be)
transfer books of the Company are open. Prior to the exercise of the Rights
evidenced thereby, the holder of a Right Certificate shall not be entitled to
any rights of a holder of Preferred Shares (or Common Shares and/or other
securities, as the case may be) for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled
to receive any notice of any proceedings of the Company, except as provided
herein.

         Section 11. Adjustment of Purchase Price, Number of Shares or Number
of Rights. The Purchase Price, the number and kind of shares covered by each
Right and the number of Rights outstanding are subject to adjustment from time
to time as provided in this Section 11.

          (a) (i) In the event the Company shall at any time after the date of
     this Agreement (A) declare a dividend on the Preferred Shares payable in
     Preferred Shares, (B) subdivide the outstanding Preferred Shares into a
     greater number of Preferred Shares, (C) combine the outstanding Preferred
     Shares into a smaller number of Preferred Shares or (D) issue any shares
     of its capital stock in a reclassification of the Preferred Shares, except
     as otherwise provided in this Section 11(a) and Section 7(e) hereof, the
     Purchase Price in effect at the time of the record date for such dividend
     or of the effective date of such subdivision, combination or
     reclassification, and the number and kind of shares of capital stock
     issuable on such date, shall be proportionately adjusted so that the
     holder of



                                      -22-

<PAGE>


     any Right exercised after such time shall be entitled to receive the
     aggregate number and kind of shares of capital stock which, if such Right
     had been exercised immediately prior to such date and at a time when the
     Preferred Shares transfer books of the Company were open, he would have
     owned upon such exercise and been entitled to receive by virtue of such
     dividend, subdivision, combination or reclassification; provided, however,
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right. If an event
     occurs which would require an adjustment under both Section 11(a)(i) and
     Section 11(a)(ii), the adjustment provided for in this Section 11(a)(i)
     shall be in addition to, and shall be made prior to, any adjustment
     required pursuant to Section 11(a)(ii).

          (ii) Subject to Section 24 of this Agreement, in the event any Person
     becomes an Acquiring Person, each holder of a Right, except as provided
     below and in Section 7(e) hereof, shall thereafter have a right to
     receive, upon exercise thereof at a price equal to the then current
     Purchase Price multiplied by the number of one one-hundredths of a
     Preferred Share for which a Right is then exercisable, in accordance with
     the terms of this Agreement and in lieu of Preferred Shares, such number
     of Common Shares of the Company as shall equal the result obtained by (x)
     multiplying the then current Purchase Price by the number of one
     one-hundredths of a Preferred Share for which a Right is then exercisable
     and dividing that product by (y) 50% of the then current per share market
     price of the Company's Common Shares (determined pursuant to Section 11(d)
     hereof)



                                      -23-

<PAGE>


     on the date of the occurrence of such event. In the event that any Person
     shall become an Acquiring Person and the Rights shall then be outstanding,
     the Company shall not take any action which would eliminate or diminish
     the benefits intended to be afforded by the Rights.

          (iii) In lieu of issuing Common Shares of the Company in accordance
     with Section 11(a)(ii) hereof, the Company may, in the sole discretion of
     the Board of Directors, elect to (and, in the event that the Board of
     Directors has not exercised the exchange right contained in Section 24
     hereof and there are not sufficient issued but not outstanding and
     authorized but unissued Common Shares to permit the exercise in full of
     the Rights in accordance with Section 11(a)(ii), the Company shall) take
     all such action as may be necessary to authorize, issue or pay, upon the
     exercise of the Rights, cash (including by way of a reduction of the
     Purchase Price), property, other securities or any combination thereof
     having an aggregate value equal to the value of the Common Shares of the
     Company which otherwise would have been issuable pursuant to Section
     11(a)(ii), which aggregate value shall be determined by a majority of the
     Board of Directors. For purposes of the preceding sentence, the value of
     the Common Shares shall be determined pursuant to Section 11(d) hereof and
     the value of any equity securities which a majority of the Board of
     Directors determines to be a "common stock equivalent" (including the
     Preferred Shares, in such ratio as the Board of Directors shall determine)
     shall be deemed to have the same value as the Common Shares. Any such
     election by the Board of Directors must be made and publicly announced
     within 60 days following the date on



                                      -24-

<PAGE>


     which the event described in Section 11(a)(ii) shall have occurred.
     Following the occurrence of the event described in Section 11(a)(ii), a
     majority of the Board of Directors then in office may suspend the
     exercisability of the Rights for a period of up to 60 days following the
     date on which the event described in Section 11(a)(ii) shall have occurred
     to the extent that such directors have not determined whether to exercise
     the Company's right of election under this Section 11(a)(iii). In the
     event of any such suspension, the Company shall issue a public
     announcement stating that the exercisability of the Rights has been
     temporarily suspended.

         (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares (as defined in Section 11(d)) on
such record date, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
Preferred Shares which the aggregate offering price of the total number of
Preferred Shares and/or equivalent preferred shares so to be offered (and/or
the aggregate initial



                                      -25-

<PAGE>


conversion price of the convertible securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number
of Preferred Shares outstanding on such record date plus the number of
additional Preferred Shares and/or equivalent preferred shares to be offered
for subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board
of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be binding on the Rights Agent.
Preferred Shares owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation. Such adjustment
shall be made successively whenever such a record date is fixed; and in the
event that such rights, options or warrants are not so issued, the Purchase
Price shall be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

         (c) In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of
indebtedness or assets (other than a regular quarterly cash dividend or a
dividend payable in Preferred Shares) or subscription rights or warrants
(excluding those referred to in Section 11(b) hereof), the Purchase Price to be
in effect after such record date shall be



                                      -26-

<PAGE>


determined by multiplying the Purchase Price in effect immediately prior to
such record date by a fraction, the numerator of which shall be the then
current per share market price of the Preferred Shares on such record date,
less the fair market value (as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent) of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
current per share market price of the Preferred Shares; provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right
be less than the aggregate par value of the shares of capital stock of the
Company to be issued upon exercise of one Right. Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

          (d) (i) For the purpose of any computation hereunder, other than
     under Section 11(a)(iii) hereof, the "current per share market price" of
     any security (a "Security" for the purpose of this Section 11(d)(i)) on
     any date shall be deemed to be the average of the daily closing prices per
     share of such Security for the 30 consecutive Trading Days (as such term
     is hereinafter defined) immediately prior to such date, and for the
     purpose of any computation under Section 11(a)(iii) hereof, the "current
     per share market price" of a Security on any date shall be deemed to be
     the average of the daily closing prices per share of such Security for
     thirty (30) consecutive Trading Days immediately prior to such



                                      -27-

<PAGE>


     date; provided, however, that in the event that the current per share
     market price of the Security is determined during a period following the
     announcement by the issuer of such Security of (A) a dividend or
     distribution on such Security payable in shares of such Security or
     securities convertible into such shares (other than the Rights), or (B)
     any subdivision, combination or reclassification of such Security and
     prior to the expiration of 30 Trading Days after the ex-dividend date for
     such dividend or distribution, or the record date for such subdivision,
     combination or reclassification, then, and in each such case, the "current
     per share market price" shall be appropriately adjusted to reflect the
     current market price per share equivalent (ex-dividend) of such Security.
     The closing price for each day shall be the last sale price, regular way,
     or, in case no such sale takes place on such day, the average of the
     closing bid and asked prices, regular way, in either case as reported in
     the principal consolidated transaction reporting system with respect to
     securities listed or admitted to trading on the New York Stock Exchange
     or, if the Security is not listed or admitted to trading on the New York
     Stock Exchange, as reported in the principal consolidated transaction
     reporting system with respect to securities listed on the principal
     national securities exchange on which the Security is listed or admitted
     to trading or, if the Security is not listed or admitted to trading on any
     national securities exchange, the last quoted price or, if not so quoted,
     the average of the high bid and low asked prices in the over-the-counter
     market, as reported by the National Association of Securities Dealers,
     Inc. Automated Quotation System ("NASDAQ") or such other system then in
     use, or, if on any such date the Security is not quoted by any such
     organization,



                                      -28-

<PAGE>


     the average of the closing bid and asked prices as furnished by a
     professional market maker making a market in the Security selected by the
     Board of Directors of the Company. If on any such date no market maker is
     making a market in the Security, the fair value of such Security on such
     date (as determined in good faith by the Board of Directors of the
     Company) shall be used. The term "Trading Day" shall mean a day on which
     the principal national securities exchange on which the Security is listed
     or admitted to trading is open for the transaction of business or, if the
     Security is not listed or admitted to trading on any national securities
     exchange, a Business Day.

          (ii) For the purpose of any computation hereunder, the "current per
     share market price" of the Preferred Shares shall be determined in
     accordance with the method set forth in Section 11(d)(i). If the Preferred
     Shares are not publicly traded, the "current per share market price" of
     the Preferred Shares shall be conclusively deemed to be the current per
     share market price of the Common Shares of the Company as determined
     pursuant to Section 11(d)(i) (appropriately adjusted to reflect any stock
     split, stock dividend or similar transaction occurring after the date
     hereof), multiplied by one hundred. If neither the Common Shares of the
     Company nor the Preferred Shares are publicly held or so listed or traded,
     "current per share market price" shall mean the fair value per share as
     determined in good faith by the Board of Directors of the Company, whose
     determination shall be described in a statement filed with the Rights
     Agent.

         (e) Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least



                                      -29-

<PAGE>


1% in the Purchase Price; provided, however, that any adjustments which by
reason of this Section 11(e) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Section 11 shall be made to the nearest cent or to the nearest one
one-millionth of a Preferred Share or one ten-thousandth of any other share or
security, as the case may be. Notwithstanding the first sentence of this
Section 11(e), any adjustment required by this Section 11 shall be made no
later than the earlier of (i) three years from the date of the transaction
which requires such adjustment or (ii) the date of the expiration of the right
to exercise any Rights.

         (f) If as a result of an adjustment made pursuant to Section 11(a) or
Section 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock of the Company other than
Preferred Shares, thereafter the number of such other shares so receivable upon
exercise of any Right shall be subject to adjustment from time to time in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to the Preferred Shares contained in this Section 11, and the
provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares
shall apply on like terms to any such other shares.

         (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

         (h) Unless the Company shall have exercised its election as provided
in Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Sections 11(b)



                                      -30-

<PAGE>


and (c), each Right outstanding immediately prior to the making of such
adjustment shall thereafter evidence the right to purchase, at the adjusted
Purchase Price, that number of one one-hundredths of a Preferred Share
(calculated to the nearest one one-millionth of a Preferred Share) obtained by
(i) multiplying (x) the number of one one-hundredths of a share covered by a
Right immediately prior to this adjustment by (y) the Purchase Price in effect
immediately prior to such adjustment of the Purchase Price and (ii) dividing
the product so obtained by the Purchase Price in effect immediately after such
adjustment of the Purchase Price.

         (i) The Company may elect on or after the date of any adjustment of
the Purchase Price to adjust the number of Rights, in substitution for any
adjustment in the number of one one-hundredths of a Preferred Share purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price. The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made. This record date
may be the date on which the Purchase Price is adjusted or any day thereafter,
but, if the Right Certificates have been issued, shall be at least 10 days
later than the date of the public announcement. If Right Certificates have been
issued, upon each adjustment



                                      -31-

<PAGE>


of the number of Rights pursuant to this Section 11(i), the Company shall, as
promptly as practicable, cause to be distributed to holders of record of Right
Certificates on such record date Right Certificates evidencing, subject to
Section 14 hereof, the additional Rights to which such holders shall be
entitled as a result of such adjustment, or, at the option of the Company,
shall cause to be distributed to such holders of record in substitution and
replacement for the Right Certificates held by such holders prior to the date
of adjustment, and upon surrender thereof, if required by the Company, new
Right Certificates evidencing all the Rights to which such holders shall be
entitled after such adjustment. Right Certificates so to be distributed shall
be issued, executed and countersigned in the manner provided for herein and
shall be registered in the names of the holders of record of Right Certificates
on the record date specified in the public announcement.

         (j) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-hundredths of a Preferred Share issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one
one-hundredths of a Preferred Share which were expressed in the initial Right
Certificates issued hereunder.

         (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below one one-hundredth of the then par value, if any, of
the Preferred Shares issuable upon exercise of the Rights, the Company shall
take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid
and nonassessable Preferred Shares at such adjusted Purchase Price.



                                      -32-

<PAGE>


         (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date
of the Preferred Shares and other capital stock or securities of the Company,
if any, issuable upon such exercise over and above the Preferred Shares and
other capital stock or securities of the Company, if any, issuable upon such
exercise on the basis of the Purchase Price in effect prior to such adjustment;
provided, however, that the Company shall deliver to such holder a due bill or
other appropriate instrument evidencing such holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

         (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it in its sole discretion shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to hereinabove in Section 11(b), hereafter made by the
Company to holders of its Preferred Shares shall not be taxable to such
stockholders.

         (n) The Company covenants and agrees that, after the Distribution
Date, it will not, except as permitted by Sections 23, 24 and 27 hereof, take
(nor will it permit any of its Subsidiaries to take) any action if at the time
such action is taken it is reasonably foreseeable that



                                      -33-

<PAGE>


such action will diminish substantially or otherwise eliminate the benefits
intended to be afforded by the Rights.

         (o) The Company covenants and agrees that, except for the transactions
contemplated by the Combination Agreement, it shall not, at any time after the
Distribution Date, (i) combine or consolidate with any other Person (other than
a Subsidiary of the Company in a transaction which complies with Section
11(n)), (ii) merge with or into any other Person (other than a Subsidiary of
the company in a transaction which complies with Section 11(n)), or (iii) sell
or transfer (or permit any of its Subsidiaries to sell or transfer), in one or
more transactions, assets or earning power aggregating more than 50% of the
assets or earning power of the Company and its Subsidiaries (taken as a whole)
to any other Person or Persons (other than the Company an/or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(n)) if (x) at the time of or immediately after such combination,
consolidation, merger or sale there are any rights, warrants or other
instruments or securities outstanding or agreements in effect which would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately
after such combination, combination, merger or sale, the stockholders of the
Person who constitutes, or would constitute, the "Principal Party" for purposes
of Section 13(a) hereof shall have received a distribution of Rights previously
owned by such Person or any of its Affiliates and Associates.

         (p) In the event that at any time after the date of this Agreement and
prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the



                                      -34-

<PAGE>


Common Shares (by reclassification or otherwise than by payment of dividends in
Common Shares) into a greater or lesser number of Common Shares, then in any
such case (i) the number of one one-hundredths of a Preferred Share purchasable
after such event upon proper exercise of each Right shall be determined by
multiplying the number of one one-hundredths of a Preferred Share so
purchasable immediately prior to such event by a fraction, the numerator of
which is the number of Common Shares outstanding immediately before such event
and the denominator of which is the number of Common Shares outstanding
immediately after such event, and (ii) each Common Share outstanding
immediately after such event shall have issued with respect to it that number
of Rights which each Common Share outstanding immediately prior to such event
had issued with respect to it. The adjustments provided for in this Section
11(p) shall be made successively whenever such a dividend is declared or paid
or such a subdivision, combination or consolidation is effected.

         (q) So long as the shares issuable upon the exercise of the Rights may
be listed on any national securities exchange or quotation service, the Company
shall use its best efforts to cause, from and after such time as the Rights
become exercisable, all shares reserved for such issuance to be listed on such
exchange or quotation service upon official notice of issuance upon such
exercise.

         (r) The Company shall use its best efforts to (i) file, as soon as
practicable following the first occurrence of a Triggering Event, a
registration statement under the Securities Act with respect to the securities
purchasable upon exercise of the Rights on an appropriate form, (ii) cause such
registration statement to become effective as soon as practicable after such
filing, and



                                      -35-

<PAGE>


(iii) cause such registration statement to remain effective (with a prospectus
at all times meeting the requirements of the Securities Act) until the date of
the Expiration Date. The Company will also take such action as may be
appropriate under the blue sky laws of the various states. The Company may
temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file such registration
statement or in order to comply with such blue sky laws. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended. A further public
announcement shall state the termination of such suspension.

         Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with
Section 25 hereof. The Rights Agent shall be fully protected in relying on any
such certificate and on any adjustment therein contained and may assume that no
adjustment has been made unless and until it shall have received such
certificate.

         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power.

         (a) If after the Shares Acquisition Date, directly or indirectly, (x)
the Company shall consolidate with, or merge with and into, any other Person,
(y) any Person shall consolidate with the Company, or merge with and into the
Company and the Company shall be the continuing or



                                      -36-

<PAGE>


surviving corporation of such merger and, in connection with such merger, all
or part of the Common Shares shall be changed into or exchanged for stock or
other securities of any other Person (or the Company) or cash or any other
property, or (z) the Company shall sell or otherwise transfer (or one or more
of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
Person or Persons other than the Company or one or more of its wholly-owned
Subsidiaries, then, and in each such case, proper provision shall be made so
that (i) each holder of a Right (except as otherwise provided herein) shall
thereafter have the right to receive, upon the exercise thereof at a price
equal to the then current Purchase Price multiplied by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of validly authorized and issued, fully paid, non-assessable and
freely tradeable Common Shares of the Principal Party (as hereinafter defined),
free and clear of all liens, rights of call or first refusal, encumbrances or
other adverse claims, as shall equal the result obtained by (A) multiplying the
then current Purchase Price by the number of one one-hundredths of a Preferred
Share for which a Right is then exercisable (or, if such Right is not then
exercisable for a number of one one-hundredths of a Preferred Share, the number
of such fractional shares for which it was exercisable immediately prior to an
event described under Section 11(a)(ii) hereof) and dividing that product by
(B) 50% of the then current per share market price of the Common Shares of such
Principal Party (determined pursuant to Section 11(d) hereof) on the date of
consummation of such consolidation, merger, sale or transfer; (ii)



                                      -37-

<PAGE>


such Principal Party shall thereafter be liable for, and shall assume, by
virtue of such consolidation, merger, sale or transfer, or otherwise, all the
obligations and duties of the Company pursuant to this Agreement; (iii) the
term "Company" shall thereafter be deemed to refer to such Principal Party and
(iv) such Principal Party shall take such steps (including, but not limited to,
the reservation of a sufficient number of its Common Shares in accordance with
Section 9 hereof) in connection with such consummation as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to its Common Shares thereafter deliverable upon
the exercise of the Rights.

         (b) "Principal Party" shall mean:

          (i) In the case of any transaction described in (x) or (y) of the
     first sentence of Section 13(a), the Person that is the issuer of any
     securities into which Common Shares of the Company are converted in such
     merger or consolidation, and if no securities are so issued, the Person
     that is the continuing or surviving entity of such merger or consolidation
     (including the Company if applicable); and

          (ii) in the case of any transaction described in (z) of the first
     sentence in Section 13(a), the Person that is the party receiving the
     greatest portion of the assets or earning power transferred pursuant to
     such transaction or transactions;

provided, however, that in any such case described in clauses (b)(i) and
(b)(ii): (1) if the Common Shares of such Person are not at such time and have
not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, and such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been



                                      -38-

<PAGE>


so registered, "Principal Party" shall refer to such other Person; (2) in case
such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of two or more of which are and have been so registered,
"Principal Party" shall refer to whichever of such Persons is the issuer of the
Common Shares having the greatest aggregate market value; and (3) in case such
Person is owned, directly or indirectly, by a joint venture formed by two or
more Persons that are not owned, directly or indirectly, by the same Person,
the rules set forth in (1) and (2) above shall apply to each of the chains of
ownership having an interest in such joint venture as if such party were a
"Subsidiary" of both or all of such joint venturers and the Principal Parties
in each such chain shall bear the obligations set forth in this Section 13 in
the same ratio as their direct or indirect interests in such Person bear to the
total of such interests.

         (c) The Company shall not consummate any such consolidation, merger,
sale or transfer unless the Principal Party shall have sufficient Common Shares
authorized to permit the full exercise of the Rights and prior thereto the
Company and such Principal Party shall have executed and delivered to the
Rights Agent a supplemental agreement providing for the terms set forth in
paragraphs (a) and (b) of this Section 13 and further providing that, as soon
as practicable after the date of any consolidation, merger or sale of assets
mentioned in paragraph (a) of this Section 13, the Principal Party will:

          (i) prepare and file a registration statement under the Securities
     Act, with respect to the Rights and the securities purchasable upon
     exercise of the Rights on an appropriate form, and will use its best
     efforts to cause such registration statement to (A) become effective as
     soon as practicable after such filing and (B) remain effective (with a



                                      -39-

<PAGE>


     prospectus at all times meeting the requirements of the Securities Act)
     until the Expiration Date;

          (ii) deliver to holders of the Rights historical financial statements
     for the Principal Party and each of its Affiliates which comply in all
     respects with the requirements for registration on Form 10 under the
     Exchange Act; and

          (iii) take such actions as may be necessary or appropriate under the
     blue sky laws of the various states.

The provisions of this Section 13 shall similarly apply to successive mergers
or consolidations or sales or other transfers. In the event that one of the
transactions described in this Section 13(a) shall occur at any time after the
occurrence of a transaction described in Section 11(a)(ii) hereof, the Rights
which have not theretofore been exercised shall thereafter become exercisable
in the manner described in Section 13(a).

         (d) In no event shall the Rights Agent have any liability in respect
of any such Principal Party transactions, including without limitation, the
propriety thereof. The Rights Agent may rely and be fully protected in relying
upon a certificate of the Company stating that the provisions of this Section
13 have been fulfilled. Notwithstanding anything in this Agreement to the
contrary, the prior written consent of the Rights Agent must be obtained in
connection with any supplemental agreement which alters the rights or duties of
the Rights Agent.

         Section 14. Fractional Rights and Fractional Shares. (a) The Company
shall not be required to issue fractions of Rights or to distribute Right
Certificates which evidence fractional



                                      -40-

<PAGE>


Rights. In lieu of such fractional Rights, there may be paid to the registered
holders of the Right Certificates with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of
the current market value of a whole Right. For the purposes of this Section
14(a), the current market value of a whole Right shall be the closing price of
the Rights for the Trading Day immediately prior to the date on which such
fractional Rights would have been otherwise issuable. The closing price for any
day shall be the last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices, regular
way, in either case as reported in the principal consolidated transaction
reporting system with respect to securities listed or admitted to trading on
the New York Stock Exchange or, if the Rights are not listed or admitted to
trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on
any national securities exchange, the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter
market, as reported by NASDAQ or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of
the closing bid and asked prices as furnished by a professional market maker
making a market in the Rights selected by the Board of Directors of the
Company. If on any such date no such market maker is making a market in the
Rights, the fair value of the Rights on such date as determined in good faith
by the Board of Directors of the Company shall be used.



                                      -41-

<PAGE>


         (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-hundredth of a Preferred Share). Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred
Share may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; provided, that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares
that are not integral multiples of one one-hundredth of a Preferred Share, the
Company may pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the
same fraction of the current market value of one one-hundredth of a Preferred
Share. For the purposes of this Section 14(b), the current market value of one
one-hundredth of a Preferred Share shall be one one-hundredth of the closing
price of a Preferred Share (as determined pursuant to the second sentence of
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
such exercise.

         (c) Following the occurrence of a Triggering Event, the Company shall
not be required to issue fractions of Common Shares upon exercise of the Rights
or to distribute certificates which evidence fractional Common Shares. In lieu
of fractional Common Shares, the Company may pay to the registered holders of
Right Certificates at the time such Rights are



                                      -42-

<PAGE>


exercised as herein provided an amount in cash equal to the same fraction of
the current market value of one Common Share. For purposes of this Section
14(c), the current market value of one Common Share shall be the closing price
of one Common Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

         (d) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of
the Common Shares); and any registered holder of any Right Certificate (or,
prior to the Distribution Date, of the Common Shares), without the consent of
the Rights Agent or of the holder of any other Right Certificate (or, prior to
the Distribution Date, of the Common Shares), may, in his own behalf and for
his own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Right Certificate in the manner
provided in such Right Certificate and in this Agreement. Without limiting the
foregoing or any remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Agreement and will be entitled



                                      -43-

<PAGE>


to specific performance of the obligations under, and injunctive relief against
actual or threatened violations of the obligations of any Person subject to,
this Agreement.

         Section 16. Agreement of Right Holders. Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

         (a) prior to the Distribution Date, the Rights will be transferable
only in connection with the transfer of the Common Shares;

         (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the office of the Rights Agent designated for such purposes, duly endorsed or
accompanied by a proper instrument of transfer and with appropriate forms and
certificates fully executed;

         (c) subject to Sections 6 and 7, the Company and the Rights Agent may
deem and treat the person in whose name the Right Certificate (or, prior to the
Distribution Date, the associated Common Shares certificate) is registered as
the absolute owner thereof and of the Rights evidenced thereby (notwithstanding
any notations of ownership or writing on the Right Certificates or the
associated Common Shares certificate made by anyone other than the Company or
the Rights Agent) for all purposes whatsoever, and neither the Company nor the
Rights Agent shall be affected by any notice to the contrary; and

         (d) notwithstanding anything in this Agreement to the contrary,
neither the Company nor the Rights Agent shall have any liability to any holder
of a Right or any other Person as a result of its inability to perform any of
its obligations under this Agreement by reason of any



                                      -44-

<PAGE>


preliminary or permanent injunction or other order, decree or ruling issued by
a court of competent jurisdiction or by a governmental, regulatory or
administrative agency or commission, or any statute, rule, regulation or
executive order promulgated or enacted by any governmental authority
prohibiting or otherwise restraining performance of such obligation.

         Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or
any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

         Section 18. Concerning the Rights Agent. The Company agrees to pay to
the Rights Agent such compensation as shall be agreed to in writing between the
Company and the Rights Agent for all services rendered by it hereunder and,
from time to time, on demand of the Rights Agent, its reasonable expenses and
counsel fees and other disbursements incurred in the administration and
execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless



                                      -45-

<PAGE>


against, any loss, liability, or expense, incurred without negligence, bad
faith or willful misconduct on the part of the Rights Agent, for anything done
or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including the costs and expenses of defending
against any claim of liability arising, directly or indirectly, therefrom.

         The Rights Agent shall be protected and shall incur no liability for,
or in respect of any action taken, suffered or omitted by it in connection
with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, opinion, notice, instruction,
direction, consent, certificate, statement, or other paper or document believed
by it to be genuine and to be signed, executed by the proper person or persons,
or otherwise upon the advice of counsel as set forth in Section 20 hereof.

         The provisions of this Section 18 shall survive the expiration of the
Rights and the termination of this Agreement.

         Section 19. Merger or Consolidation or Change of Name of Rights Agent.
Any Person into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to all or substantially all the
stock transfer or corporate trust business of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto;



                                      -46-

<PAGE>


provided, that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at
the time such successor Rights Agent shall succeed to the agency created by
this Agreement, any of the Right Certificates shall have been countersigned but
not delivered; any such successor Rights Agent may adopt the countersignature
of the predecessor Rights Agent and deliver such Right Certificates so
countersigned; and in case at that time any of the Right Certificates shall not
have been countersigned, any successor Rights Agent may countersign such Right
Certificates either in the name of the predecessor Rights Agent or in the name
of the successor Rights Agent; and in all such cases such Right Certificates
shall have the full force provided in the Right Certificates and in this
Agreement.

         In case at any time the name of the Rights Agent shall be changed and
at such time any of the Right Certificates shall have been countersigned but
not delivered, the Rights Agent may adopt the countersignature under its prior
name and deliver Right Certificates so countersigned; and in case at that time
any of the Right Certificates shall not have been countersigned, the Rights
Agent may countersign such Right Certificates either in its prior name or in
its changed name; and in all such cases such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

         Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations expressly imposed by this Agreement, and no implied
duties or obligations shall be read into this Agreement against the Rights
Agent, upon the following terms and conditions, by



                                      -47-

<PAGE>


all of which the Company and the holders of Right Certificates, by their
acceptance thereof, shall be bound:

         (a) The Rights Agent may consult with legal counsel satisfactory to it
(who may be legal counsel for the Company), and the opinion of such counsel
shall be full and complete authorization and protection to the Rights Agent and
the Rights Agent shall incur no liability or responsibility to the Company or
to any holder of any Right Certificate in respect of any action taken or
omitted by it in good faith and in accordance with such opinion.

         (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering or omitting
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board,
the Chief Executive Officer, any Vice Chairman, the President, any Vice
President, the Treasurer or the Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by it under the provisions
of this Agreement in reliance upon such certificate.

         (c) The Rights Agent shall be liable hereunder to the Company only
for, and shall indemnify and hold harmless the Company from and against, any
and all losses, liabilities, costs, damages and expenses (including attorney's
fees) arising out of or in connection with, the Rights Agents' gross
negligence, bad faith or willful misconduct.



                                      -48-

<PAGE>


         (d) The Rights Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained in this Agreement or in the Right
Certificates (except its countersigna ture thereof) or be required to verify
the same, but all such statements and recitals are and shall be deemed to have
been made by the Company only.

         (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including
the Rights becoming void pursuant to Section 7(e) hereof) or any adjustment in
the terms of the Rights (including the manner, method or amount thereof)
provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except
with respect to the exercise of Rights evidenced by Right Certificates after
receipt of a certificate furnished pursuant to Section 12 describing a change
or adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any
Preferred Shares or Common Shares to be issued pursuant to this Agreement or
any Right Certificate or as to whether any Preferred Shares or Common Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable, nor shall the Rights Agent be responsible for the legality of
the terms hereof in its capacity as an administrative agent.



                                      -49-

<PAGE>


         (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be
required by the Rights Agent for the carrying out or performing by the Rights
Agent of the provisions of this Agreement.

         (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, any Vice
Chairman, the President, any Vice President, the Secretary or the Treasurer of
the Company, and to apply to such officers for advice or instructions in
connection with its duties, and it shall not be liable for any action taken or
suffered by it in good faith in accordance with instructions of any such
officer or for any delay in acting while waiting for those instructions. Any
application by the Rights Agent for written instructions from the Company may,
at the option of the Rights Agent, set forth in writing any action proposed to
be taken or omitted by the Rights Agent under this Agreement and the date on
and/or after which such action shall be taken or such omission shall be
effective. The Rights Agent shall not be liable for any action taken by, or
omission of, the Rights Agent in accordance with a proposal included in any
such application on or after the date specified in such application (which date
shall not be less than five Business Days after the date such application is
given, unless any such officer shall have consented in writing to an earlier
date) unless, prior to taking any such action (or the effective date in the
case of an omission), the Rights Agent shall have received written instructions
in response to such application specifying the action to be taken or omitted.

         (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or
other securities of the Company or its Subsidiaries or become pecuniarily
interested in any transaction in which the Company or its Subsidiaries may be
interested, or contract with or lend money to the Company or its Subsidiaries
or otherwise act as fully and freely as though it were not Rights Agent under
this Agreement. Nothing herein shall preclude the Rights Agent from acting in
any other capacity for the Company or its Subsidiaries or for any other legal
entity.

         (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable
or accountable for any act, default, neglect or misconduct of any such
attorneys or agents or for any loss to the Company resulting from any such act,
default, neglect or misconduct, provided reasonable care was exercised in the
selection and continued employment thereof.

         (j) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise, transfer, split-up, combination or exchange, the
certificate attached to the form of assignment or form of election to purchase,
as the case may be, has either not been completed or indicates an affirmative
response to clause 1 and/or 2 thereof, the Rights Agent shall not take any
further action with respect to such requested exercise, transfer, split-up,
combination or exchange without first consulting with the Company.

         (k) The Rights Agent shall not be under any duty or responsibility to
insure compliance with any applicable federal or state securities laws in
connection with the issuance, transfer or exchange of Right Certificates.

         (l) The Rights Agent shall be under no obligation to institute any
action, suit or legal proceeding or to take any other action likely to involve
expense unless the Company or one or more holders of Right Certificates shall
furnish the Rights Agent with security and indemnity to its satisfaction for
any costs and expenses which may be incurred.

         (m) The Rights Agent shall not be liable for failure to perform any
duties except as specifically set forth herein and no implied covenants or
obligations shall be read into this Agreement against the Rights Agent whose
duties and obligations are ministerial and shall be determined solely by the
express provisions hereof.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer
agent of the Common Shares or Preferred Shares by registered or certified mail,
and to the holders of the Right Certificates by first-class mail. The Company
may remove the Rights Agent or any successor Rights Agent upon 30 days' notice
in writing, mailed to the Rights Agent or successor Rights Agent, as the case
may be, and to each transfer agent of the Common Shares or Preferred Shares by
registered or certified mail, and to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a



                                      -52-

<PAGE>


period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation, bank or other entity organized and doing business under the laws
of the United States or of any other state of the United States, which is
authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination by federal or state authority and
which has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $100 million or is an Affiliate of an entity having a
combined capital and surplus of at least $100 million. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and
transfer to the successor Rights Agent any property at the time held by it
hereunder, and execute and deliver any further assurance, conveyance, act or
deed necessary for the purpose. Not later than the effective date of any such
appointment the Company shall file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Common Shares or
Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect



                                      -53-

<PAGE>


the legality or validity of the resignation or removal of the Rights Agent or
the appointment of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Right Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Right Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or
change in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of Common Shares following the Distribution Date and
prior to the redemption or expiration of the Rights, the Company (a) shall,
with respect to Common Shares so issued or sold pursuant to the exercise of
options or under any employee plan or arrangement, or upon the exercise,
conversion or exchange of securities hereinafter issued by the Company, and (b)
may, in any other case, if deemed necessary or appropriate by the Board of
Directors of the Company, issue Right Certificates representing the appropriate
number of Rights in connection with such issuance or sale; provided, however,
that (i) no such Right Certificate shall be issued, if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Right Certificate would be issued, and (ii) no such Right
Certificate shall be issued, if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

         Section 23.  Redemption.

         (a) The Board of Directors of the Company may, at its option, at any
time prior to such time as any Person becomes an Acquiring Person, redeem all
but not less than all the then outstanding Rights at a redemption price of
$0.01 per Right, appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof (such
redemption price being hereinafter referred to as the "Redemption Price"). The
redemption of the Rights by the Board of Directors may be made effective at
such time on such basis and with such conditions as the Board of Directors in
its sole discretion may establish. If redemption of the Rights is to be
effective as of a future date, the Rights shall continue to be exercisable,
subject to Section 7 hereof, until the effective date of the redemption,
provided that nothing contained herein shall preclude the Board of Directors
from subsequently causing the Rights to be redeemed at a date earlier than the
previously scheduled effective date of the redemption. The Company may, at its
option, pay the Redemption Price in cash, Common Shares (based on the current
per share market price of the Common Shares at the time of redemption) or any
other form of consideration deemed appropriate by the Board of Directors.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights (or at the effective time of such
redemption established by the Board of Directors of the Company pursuant to
paragraph (a) of this Section 23), and without any further action and without
any notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
The Company shall promptly give public notice, with simultaneous written notice
to the Rights



                                      -55-

<PAGE>


Agent, of any such redemption; provided, however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such
redemption. Within 10 days after such action of the Board of Directors ordering
the redemption of the Rights or, if later, the effectiveness of the redemption
of the Rights pursuant to the last sentence of paragraph (a), the Company shall
mail a notice of redemption to all the holders of the then outstanding Rights
at their last addresses as they appear upon the registry books of the Rights
Agent or, prior to the Distribution Date, on the registry books of the transfer
agent for the Common Shares. Any notice which is mailed in the manner herein
provided shall be deemed given, whether or not the holder receives the notice.
Each such notice of redemption will state the method by which the payment of
the Redemption Price will be made. The Company may, at its option, discharge
all of its obligations with respect to the Rights by (i) issuing a press
release announcing the manner of redemption of the Rights, (ii) depositing with
a bank or trust company having a capital and surplus of at least $100,000,000,
funds necessary for such redemption, in trust, to be applied to the redemption
of the Rights so called for redemption and (iii) arranging for the mailing of
the Redemption Price to the registered holders of the Rights; then, and upon
such action, all outstanding Rights Certificates shall be null and void without
further action by the Company. Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23, in
Section 24 hereof, or in connection with the purchase of Common Shares prior to
the Distribution Date.

         Section 24. Exchange. (a) The Board of Directors of the Company may,
at its option, at any time after a Triggering Event, exchange all or part of
the then outstanding and exercisable



                                      -56-

<PAGE>


Rights (which shall not include Rights that have become void pursuant to the
provisions of Section 7(e) hereof) for Common Shares at an exchange ratio of
one Common Share per Right, appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the date hereof (such
exchange ratio being hereinafter referred to as the "Exchange Ratio").
Notwithstanding the foregoing, the Board of Directors shall not be empowered to
effect such exchange at any time after any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or any such
Subsidiary, or any entity holding Common Shares for or pursuant to the terms of
any such plan), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of the Common Shares then
outstanding.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice, with simultaneous written notice to
the Rights Agent, of any such exchange; provided, however, that the failure to
give, or any defect in, such notice shall not affect the validity of such
exchange. The Company promptly shall mail a notice of any such exchange to all
of the holders of such Rights at their last addresses as they appear upon the
registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of



                                      -57-

<PAGE>


exchange will state the method by which the exchange of the Common Shares for
Rights will be effected and, in the event of any partial exchange, the number
of Rights which will be exchanged. Any partial exchange shall be effected pro
rata based on the number of Rights (other than Rights which have become void
pursuant to the provisions of Section 7(e) hereof) held by each holder of
Rights.

         (c) In any exchange pursuant to this Section 24, the Company, at its
option, may substitute Preferred Shares (or equivalent preferred shares, as
such term is defined in Section 11(b) hereof) for Common Shares exchangeable
for Rights, at the initial rate of one one-hundredth of a Preferred Share (or
equivalent preferred share) for each Common Share, as appropriately adjusted to
reflect adjustments in the voting rights of the Preferred Shares pursuant to
the terms thereof, so that the fraction of a Preferred Share delivered in lieu
of each Common Share shall have the same voting rights as one Common Share.

         (d) In the event that there shall not be sufficient Common Shares or
Preferred Shares issued but not outstanding or authorized but unissued to
permit any exchange of Rights as contemplated in accordance with this Section
24, the Company shall take all such action as may be necessary to authorize
additional Common Shares or Preferred Shares for issuance upon exchange of the
Rights.

         (e) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares.
In lieu of such fractional Common Shares, the Company shall pay to the
registered holders of the Right Certificates with regard to which such
fractional Common Shares would otherwise be issuable an amount in cash



                                      -58-

<PAGE>


equal to the same fraction of the current market value of a whole Common Share.
For the purposes of this paragraph (e), the current market value of a whole
Common Share shall be the closing price of a Common Share (as determined
pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of exchange pursuant to this Section 24.

         Section 25.  Notice of Certain Events.

         (a) In case the Company shall propose at any time after the
Distribution Date (i) to pay any dividend payable in stock of any class to the
holders of its Preferred Shares or to make any other distribution to the
holders of its Preferred Shares (other than a regular quarterly cash dividend),
(ii) to offer to the holders of its Preferred Shares rights or warrants to
subscribe for or to purchase any additional Preferred Shares or shares of stock
of any class or any other securities, rights or options, (iii) to effect any
reclassification of its Preferred Shares (other than a reclassification
involving only the subdivision of outstanding Preferred Shares), (iv) to effect
any consolidation or merger into or with, or to effect any sale or other
transfer (or to permit one or more of its Subsidiaries to effect any sale or
other transfer), in one or more transactions, of 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to, any
other Person, (v) to effect the liquidation, dissolution or winding up of the
Company, or (vi) to declare or pay any dividend on the Common Shares payable in
Common Shares or to effect a subdivision, combination or consolidation of the
Common Shares (by reclassification or otherwise than by payment of dividends in
Common Shares), then, in each such case, the Company shall give to each holder
of a Right Certificate, and to the Rights Agent, in accordance



                                      -59-

<PAGE>


with Section 26 hereof, a notice of such proposed action, which shall specify
the record date for the purposes of such stock dividend, or distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take
place and the date of participation therein by the holders of the Common Shares
and/or Preferred Shares, if any such date is to be fixed, and such notice shall
be so given in the case of any action covered by clause (i) or (ii) above at
least 10 days prior to the record date for determining holders of the Preferred
Shares for purposes of such action, and in the case of any such other action,
at least 10 days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the Common Shares and/or
Preferred Shares, whichever shall be the earlier.

         (b) In case any of the events set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate, and to the Rights Agent, in accordance with
Section 26 hereof, a notice of the occurrence of such event, which notice shall
describe such event and the consequences of such event to holders of Rights
under Section 11(a)(ii) hereof.

purposes of issuance upon the exchange of CN Exchangeable Shares (as defined in
the Combination Agreement, dated as of December 18, 1999 (the "Combination
Agreement"), by and among CN, Burlington Northern Santa Fe Corporation, the
Corporation, North American Railways, Inc. and Western Merger Sub, Inc.), such
number of shares of Common Stock as shall then be issuable upon the conversion
of (i) all outstanding CN Exchangeable Shares and (ii) all CN Exchangeable
Shares that are issuable upon the exercise of all outstanding rights to acquire
CN Exchangeable Shares.

         3. Transfer Restrictions; Legend. (a) No shares of Common Stock of the
Corporation shall be issued or transferred, and no issuance or transfer shall be
reflected on the books of the Corporation, unless a simultaneous issuance or
transfer of a like number of CN Voting Shares (as defined in the Combination
Agreement) is made to the same holder and recorded on the books of CN or, in the
case of an exchange of CN Exchangeable Shares for shares of Common Stock, the
holder of such CN Exchangeable Shares will continue to be the

                                        2

<PAGE>


holder of the corresponding CN Voting Shares upon consummation of such exchange.
The only certificate representing shares of Common Stock that a holder of Common
Stock shall be entitled to receive shall be a certificate representing both the
shares of Common Stock held by such holder and the CN Voting Shares held by such
holder.

         (b) Each certificate representing shares of Common Stock shall contain
or have affixed thereto a legend in form and substance approved by the board of
directors of the Corporation with respect to the transfer restriction set forth
in this subsection (3).

         (c) No amendment to this Restated Certificate of Incorporation shall
amend, alter, change or repeal any of the provisions of this subsection 3 unless
such amendment shall receive (i) the affirmative vote of all of the directors of
the Corporation, other than any directors who are unable to participate in the
board of directors' deliberations due to medical reasons, and (ii) the
affirmative vote of not less than 85% of the votes cast at a meeting of
stockholders at which a quorum is present, provided that such number of
affirmative votes constitutes at least a majority of the votes entitled to be
cast on such amendment by holders of the Corporation's capital stock.

         4. Appraisal Rights. Holders of Common Stock shall be entitled to
appraisal rights under Section 262 of the Delaware General Corporation Law with
respect to any matter for which holders of CN Exchangeable Shares are entitled
to appraisal or dissenters' rights under the Canadian Business Corporations Act;
provided, however, that there shall be no appraisal rights with respect to the
Merger (as defined in the Combination Agreement) or the other transactions
contemplated by the Combination Agreement.

         5. Acknowledgments. (a) Each holder of Common Stock acknowledges that
the Co-Operation Agreement (as defined in Article NINTH) provides, in part, that
CN shall not, without the prior approval of the Corporation and the holders of
Common Stock:

                  (i) issue or distribute CN Exchangeable Shares (or securities
         exchangeable for or convertible into or carrying rights to acquire CN
         Exchangeable Shares) to the holders of all or substantially all of the
         then outstanding CN Exchangeable Shares by way of stock dividend or
         other distribution, other than an issue of CN Exchangeable Shares to
         holders of CN Exchangeable Shares who exercise an option to receive
         dividends in CN Exchangeable Shares in lieu of receiving cash
         dividends;

                  (ii) issue or distribute rights, options or warrants to the
         holders of all or substantially all of the then outstanding CN
         Exchangeable Shares entitling them to subscribe for or to purchase CN
         Exchangeable Shares; or

                  (iii) issue or distribute to the holders of all or
         substantially all of the then outstanding CN Exchangeable Shares:

                                        3

<PAGE>



                        (A) shares or securities of CN of any class other than
               CN Exchangeable Shares;

                        (B) rights, options or warrants other than those
               referred to in subsection 5(a)(ii);

                        (C) evidences of indebtedness of CN; or

                        (D) assets of CN;

unless, in the case of subsections 5(a)(i) and (ii), a corresponding issue or
distribution of units comprised of shares of Common Stock and CN Voting Shares
or rights, options or warrants to acquire units comprised of shares of Common
Stock and CN Voting Shares, as applicable, is made or, in the case of subsection
5(a)(iii), the economic equivalent on a per share basis of such other shares or
securities, rights, options, warrants, evidences of indebtedness or other assets
is issued or distributed simultaneously to holders of Common Stock or unless, in
the case of a stock dividend payable in CN Exchangeable Shares, in lieu of such
stock dividend, the Corporation and CN effect a corresponding stock dividend
payable in shares of Common Stock and CN Voting Shares.

         (b) Each holder of Common Stock acknowledges that the Co-Operation
Agreement further provides, in part, that CN shall not, without the prior
approval of the Corporation and the holders of Common Stock:

                  (i) subdivide, redivide or change the then outstanding CN
         Exchangeable Shares into a greater number of CN Exchangeable Shares;

                  (ii) reduce, combine, consolidate or change the then
         outstanding CN Exchangeable Shares into a lesser number of CN
         Exchangeable Shares; or

                  (iii) reclassify or otherwise change the CN Exchangeable
         Shares or effect an amalgamation, merger, reorganization or other
         transaction affecting the CN Exchangeable Shares;

unless, in the case of subsections 5(b)(i) and (ii) above, the same or, in the
case of subsection 5(b)(iii) above, the same or an economically equivalent
change is simultaneously made to, or in the rights of the holders of, Common
Stock and CN Voting Shares. The Co-Operation Agreement further provides, in
part, that the aforesaid provisions of the Co-Operation Agreement shall not be
changed without the approval of the holders of Common Stock.

                                        4

SECTION II:   PROVISIONS RELATING TO SPECIAL VOTING STOCK

         1. Voting Rights. At all times, the one share of Special Voting Stock
shall be entitled at any relevant date to that number of votes (including for
purposes of determining the presence of a quorum) equal to the number of CN
Exchangeable Shares outstanding as of the applicable record date of the
stockholder meeting at which any matter is to be considered. In respect of all
matters concerning the voting of shares of the Corporation, except as required
by law and except as set forth in this Article FIFTH, the Common Stock and the
Special Voting Stock shall vote as a single class and such voting rights shall
be identical in all respects.

         2. No Dividends. No dividends shall be paid to the holder of the
Special Voting Stock.

         3. Liquidation Rights. The holder of the share of Special Voting Stock
shall be entitled to receive $1.00 upon the liquidation, dissolution or
winding-up of the Corporation in preference to any shares of Common Stock of the
Corporation, but only after the liquidation preference of any shares of
Preferred Stock of the Corporation has been paid.

         4. No Conversion. Except as provided in subsection (5), the Special
Voting Stock is not convertible into any other class or series of the capital
stock of the Corporation or into cash, property or other rights, and may not be
purchased or redeemed by the Corporation.

         5. Redemption; Cancellation. At such time as the Special Voting Stock
has no votes attached to it because there are no CN Exchangeable Shares
outstanding, the Special Voting Stock shall be redeemable, and shall be
redeemed, by the Corporation for par value and canceled.

         6. Restrictions. So long as the share of Special Voting Stock is
outstanding, the Corporation shall fully comply with all contractual obligations
of the Corporation associated with such CN Exchangeable Shares. So long as any
CN Exchangeable Shares shall be outstanding, the number of authorized shares of
Special Voting Stock shall not be increased or decreased and no other term of
the Special Voting Stock shall be amended, without the affirmative vote of at
least a majority of the votes entitled to be cast on such amendment by holders
of CN Exchangeable Shares.

SECTION III:  PROVISIONS RELATING TO PREFERRED STOCK

         The board of directors is expressly authorized to provide for the issue
of all or any shares of the Preferred Stock, in one or more series, and to fix
for each such series such voting powers, full or limited, or no voting powers,
and such designations, preferences and relative, participating, optional or
other special rights and such qualifications, limitations or restrictions
thereof, as shall be stated and expressed in the resolution or resolutions
adopted by the board of directors of the Corporation providing for the issue of
such series (a "Preferred Stock Designation") and as may be permitted by the
Delaware General Corporation Law. The number

                                        5

<PAGE>


of authorized shares of Preferred Stock may be increased or decreased (but not
below the number of shares thereof then outstanding) by the affirmative vote of
the holders of a majority of the voting power of all of the then outstanding
shares of the Corporation's capital stock entitled to vote generally in the
election of directors (the "Voting Stock"), voting together as single class,
without a separate vote of the holders of the Preferred Stock, or any series
thereof, unless a vote of any such holders is required pursuant to any Preferred
Stock Designation.

         SIXTH: Restrictions on the transferability of the capital stock of the
Corporation, in addition to those restrictions set forth elsewhere in this
Amended and Restated Certificate of Incorporation, are as follows:

         1. Definitions. For purposes of this Article SIXTH, the following terms
have the following meanings:

         "Act" means An Act to provide for the continuance of the Canadian
National Railway Company under the Canada Business Corporations Act and for the
issuance and sale of shares of the Company to the public, S.C. 1995, c.24
enacted on July 13, 1995;

         "Aggregate Votes" means the aggregate of the votes attached to all
voting shares of the Corporation that may ordinarily be cast to elect directors
of the Corporation;

         "associate" has the meaning set forth in subsection 6 of this Article
SIXTH;

         "control" has the meaning set forth in subsection 7 of this Article
SIXTH;

         "corporation" includes a body corporate, partnership and unincorporated
organization;

         "Maximum Individual Holdings" means voting shares to which are attached
fifteen percent (15%) of the Aggregate Votes;

         "Minister" means the Minister of Transport or such other member of the
Queen's Privy Council for Canada as may be designated by the Governor in Council
as the Minister for the purposes of the Act;

         "Ownership Rights" means, with respect to voting shares of the
Corporation, all rights attaching thereto, including the rights to vote at any
meeting of stockholders, to receive any dividends declared thereon by the
Corporation, and to receive the remaining property of the Corporation upon
liquidation, dissolution or winding-up of the Corporation (but does not include
the right to receive proceeds of sale pursuant to subsection 5 of this Article
SIXTH);

         "person" includes an individual, corporation, government, government
agency, trustee, executor, administrator and other legal representative; and

                                        6

<PAGE>


         "voting share" means a share of the Corporation carrying voting rights
under all circumstances or under some circumstances that have occurred and are
continuing, and includes a security currently convertible into such a share and
currently exercisable options and rights to acquire such a share or such a
convertible security.

         2. Constraints on Issue and Transfer. The Corporation shall not (a)
accept any subscription for its voting shares; (b) issue any of its voting
shares; or (c) register or otherwise recognize the transfer of any of its voting
shares if, as a result of such subscription, issue, transfer, purchase or
acquisition, voting shares to which are attached more than fifteen percent (15%)
of the Aggregate Votes are or would be held, beneficially owned or controlled,
directly or indirectly, by any one person together with the associates of such
person.

         3. Constraints on Ownership Rights. No person, together with his, her
or its associates, shall hold, beneficially own or control, directly or
indirectly, voting shares to which are attached more than fifteen percent (15%)
of the Aggregate Votes. Subject to subsections 4(a) and 4(b) of this Article
SIXTH, the Corporation shall refuse to recognize all Ownership Rights that would
otherwise be attached to any voting shares held, beneficially owned or
controlled, directly or indirectly, in excess of the permitted Maximum
Individual Holdings by any person, together with such person's associates.

         4. Limitation on Voting Rights; Dividend Forfeiture. (a) Where the
total number of voting shares held, beneficially owned or controlled, directly
or indirectly, by any one person together with such person's associates exceeds
the Maximum Individual Holdings, no person shall, in person or by proxy,
exercise the voting rights attached to the voting shares held, beneficially
owned or controlled, directly or indirectly, by such person or such person's
associates. If the Corporation redeems, purchases for cancellation or otherwise
acquires voting shares, and the result of such action is that any person and the
associates of that person who, prior to such action, were not in contravention
of the Maximum Individual Holdings are, after such action, in contravention,
then, notwithstanding any other provision of this Article SIXTH, the sole
consequence of such action to that person and the associates of that person, in
respect of the voting shares of that person and of the associates of that person
held, beneficially owned or controlled at the time of such action, shall be that
the number of votes attached to those voting shares shall be reduced to a number
that is the largest whole number of votes that may be attached to the voting
shares which that person and the associates of that person could hold,
beneficially own or control from time to time in accordance with the Maximum
Individual Holdings.

         (b) Where the total number of voting shares held, beneficially owned or
controlled, directly or indirectly, by any one person together with his, her or
its associates exceeds the Maximum Individual Holdings, the percentage of any
and all dividends attributable to the percentage of voting shares exceeding the
Maximum Individual Holdings shall be forfeited, including any cumulative
dividend, and the amount of dividend so forfeited shall not become

                                        7

<PAGE>


payable thereafter to any person for any reason whatsoever; provided, however,
that, notwithstanding any other provision of this Article SIXTH:

                  (i) the directors of the Corporation may determine to pay a
         dividend or to make any other distribution on voting shares that would
         otherwise be prohibited by any other provision of this Article SIXTH
         where the contravention of the Maximum Individual Holdings that gave
         rise to the prohibition was inadvertent or of a technical nature or it
         would otherwise be inequitable not to pay the dividend or make the
         distribution; and

                  (ii) where a dividend has not been paid or any other
         distribution has not been made on voting shares of a person as a result
         of a directors' determination of a contravention of the Maximum
         Individual Holdings, the directors of the Corporation shall declare and
         pay the dividend or make the distribution to the relevant person if
         they subsequently determine that no such contravention occurred.

         (c) Notwithstanding any other provision of this Article SIXTH, a
contravention of the Maximum Individual Holdings shall have no consequences
except those that are expressly provided for in this Article SIXTH. For greater
certainty, but without limiting the generality of the foregoing, (i) no
transfer, issue or ownership of, and no title to, voting shares; (ii) no
resolution of stockholders; and (iii) no act of the Corporation, including any
transfer of property to or by the Corporation, shall be invalid or otherwise
affected by any contravention of the Maximum Individual Holdings.

         5. Sale of Constrained Shares. Without limiting any of the provisions
of this Article SIXTH (but subject to subsection 4(a) of this Article SIXTH) the
Corporation may, for the purposes of enforcing any constraint imposed pursuant
to subsection 2 of this Article SIXTH, sell, as if it were the owner thereof,
any voting shares that are owned, or that the directors determine may be owned,
by any person or persons, contrary to such constraint. Such sale shall be
conducted in accordance with the procedures set forth in Part VI of the Canadian
Business Corporations Act and Part VII of the Canadian Business Corporations
Regulations with necessary modifications, as if such provisions applied to the
sale of such voting shares, and the net proceeds of the sale thereof shall be
remitted to the person or persons entitled thereto; provided, however, that (i)
in the event the Corporation elects to transfer the proceeds of any such sale to
a trust company, the trust company may be either a United States or Canadian
trust company and (ii) in the event the proceeds of any such sale are not
claimed by a person entitled to receive such proceeds within ten years after the
date of such sale, the Corporation shall be entitled to retain such proceeds.

         6. Associates. (a) For the purposes of this Article SIXTH, a person is
an "associate" of another person if:

                  (i) one is a corporation of which the other is an officer or
         director;

                                        8

<PAGE>


                  (ii) one is a corporation that is controlled by the other or
         by a group of persons of which the other is a member;

                  (iii) one is a partnership of which the other is a partner;

                  (iv) one is a trust of which the other is a trustee;

                  (v) both are corporations controlled by the same person;

                  (vi) both are members of a voting trust that relates to voting
         shares;

                  (vii) both, in the reasonable opinion of the directors of the
         Corporation, are parties to an agreement or arrangement, a purpose of
         which is to require them to act in concert with respect to their
         interests, direct or indirect, in the Corporation or are otherwise
         acting in concert with respect to those interests; or

                  (viii) both are at the same time associates, within the
         meaning of any of clauses (i) to (viii), of the same person.

         (b) Notwithstanding subsection 6(a) of this Article SIXTH, for the
purposes of this subsection 6:

                  (i) where a person who, but for this subsection 6(b), would be
         an associate of another person submits to the Corporation such
         declaration as required by the directors stating that:

                        (A) no voting shares held or to be held by the declarant
               are or will be, to the declarant's knowledge, held in the right
               of, for the use or benefit of, or under the control of, any other
               person of which, but for this subsection 6(b), the declarant
               would be an associate, and

                        (B) the declarant is not acting and will not act in
               concert with any other person with respect to their interests,
               direct or indirect, in the Corporation,

         the declarant and that other person are not associates so long as the
         directors of the Corporation are satisfied that the statements in the
         declaration are being complied with and that there are no other
         reasonable grounds for disregarding the declaration; and

                  (ii) two corporations are not associates pursuant to
         subsection 6(a) of this Article SIXTH by reason only that, under such
         subsection 6(a), each is an associate of the same individual; and

                                        9

<PAGE>


                  (iii) where it appears from the stock ledger of the
         Corporation that any person holds, beneficially owns or controls voting
         shares to which are attached not more than the lesser of two
         one-hundredths of one percent of the votes that may ordinarily be cast
         to elect directors of the Corporation and five thousand such votes,
         that person is not an associate of anyone else and no one else is an
         associate of that person.

         (c) For greater certainty, no person is presumed to be an associate of
any other person solely by reason that one of them has given the other the power
to vote or direct the voting of voting shares at a meeting of the holders of the
voting shares pursuant to a revocable proxy where the proxy is solicited solely
by means of a proxy statement issued in a public solicitation of proxies that is
made in respect of all voting shares and in accordance with applicable law.

         7. Control. For purposes of this Article SIXTH, "control" and any
derivative thereof means control in any manner that results in control in fact,
whether directly through the ownership of securities or indirectly through a
trust, an agreement or arrangement, the ownership of any body corporate or
otherwise, and, without limiting the generality of the foregoing:

         (a) a body corporate is controlled by a person if:

                  (i) securities of the body corporate to which are attached
             more than fifty percent (50%) of the votes that may be cast to
             elect directors of the body corporate are held, otherwise than by
             way of security only, by or for the benefit of that person; and

                  (ii) the votes attached to those securities are sufficient, if
             exercised, to elect a majority of the directors of the body
             corporate; and

         (b) a partnership or unincorporated organization is controlled by a
person if an ownership interest therein representing more than fifty percent
(50%) of the assets of the partnership or organization is held, otherwise than
by way of security only, by or for the benefit of that person.

         8. Joint Ownership. For the purposes of this Article SIXTH, where
voting shares are held, beneficially owned or controlled by several persons
jointly, the number of voting shares held, beneficially owned or controlled by
any one such person shall include the number of voting shares held, beneficially
owned or controlled jointly with such other persons.

         9. Exceptions. (a) Nothing in this Article SIXTH shall be construed to
apply to such a holder in respect of voting shares that:

                  (i) are held by the Minister in trust for Her Majesty in right
             of Canada;

                                       10

<PAGE>


                  (ii) are held by one or more underwriters solely for the
         purpose of distributing the shares to the public or in connection
         therewith, which shall include, without limitation, any voting shares
         acquired through the exercise of an over-allotment option or in
         stabilization transactions and, for the purposes of calculating the
         percentage of voting shares of the Corporation held, beneficially owned
         or controlled by any underwriter during the period of any distribution
         of shares (such period not terminating for the purposes of this
         provision while any over-allotment option remains unexercised and
         unexpired), shall not include any shares owned or subject to
         acquisition by such underwriter which have at the time of such
         calculation been resold;

                  (iii) are held by any person that is acting in relation to the
         shares solely in its capacity as an intermediary in the payment of
         funds or the delivery of securities or both, in connection with trades
         in securities and that provides centralized facilities for the clearing
         of trades in securities, including, without limitation, intermediaries
         such as The Canadian Depositary for Securities Limited and The
         Depository Trust Company;

                  (iv) are held by way of security only; or

                  (v) are held by any custodian, depositary or other agent
         appointed under an instalment receipt agreement or other agreement
         pursuant to which, among other things, voting shares are purchased on
         an instalment basis.

         (b) None of the restrictions set forth in this Article SIXTH shall
apply to the Special Voting Stock; provided, however, that the voting rights of
the holder of Special Voting Stock shall be included for purposes of calculating
the number of Aggregate Votes; provided further, that any holder of voting
shares shall be deemed, for purposes of determining compliance with the
requirements of subsections 2 and 3 of this Article SIXTH, to hold an additional
number of voting shares equal to the number of votes attached to the Special
Voting Share of which such holder together with such holder's associates has the
right to direct the casting as a result of holding CN Exchangeable Shares and,
if any such holder, as a result thereof, is not in compliance with subsection 3
of this Article SIXTH, subsection 4 of this Article SIXTH shall be applicable to
the votes attached to the Special Voting Share of which such holder, together
with such holder's associates, has the right to direct.

         10. By-Laws. (a) Subject to applicable law, the board of directors of
the Corporation may make, amend or repeal any by-laws required to administer the
constrained share provisions set forth in this Article SIXTH, including any
by-laws to determine the circumstances in which any declarations are required,
their form and the times when they are to be furnished.

         (b) Where a person is required to furnish a declaration pursuant to a
by-law made under subsection 10(a) of this Article SIXTH, the board of directors
of the Corporation may refuse to register a transfer of a voting share in his,
her or its name or to issue a voting share to him, her or it until that person
has furnished the declaration.

                                       11

<PAGE>


         11. Powers of Directors. (a) Subject to applicable law, in the
administration of this Article SIXTH, the directors of the Corporation shall
enjoy, in addition to the powers set forth in this Article SIXTH, all of the
powers necessary or desirable, in their opinion, to carry out the intent or
purpose of this Article SIXTH.

         (b) If the board of directors of the Corporation, acting in good faith,
determines that any persons are parties to an agreement or arrangement, a
purpose of which is to require them to act in concert with respect to their
interest, direct or indirect, in voting shares, the board of directors shall be
entitled to treat such persons as associates for the purposes of this Article
SIXTH.

power present in person or represented by proxy and voting shall decide any
question brought before such meeting, unless the question is one upon which, by

stockholders who have not consented in writing.

shall be managed and controlled by or under the direction of its Board of
Directors, which may exercise all such powers of, and do all such acts and

things as are not by law or by the Certificate of Incorporation or by these
By-laws directed or required to be exercised or done by the stockholders.

the Corporation shall consist of not less than one (1) member and not more than
ten (10) members. Within the limit above specified, the number of directors
shall be determined from time to time by resolution of the Board of Directors.

except as pro vided in the Certificate of Incorporation or Section 3 of this
Article, and each director elected shall hold office until his or her successor

announcement at the immediately preceding regular meeting. Special meetings of
the Board may be called by the Chief Executive Officer, by the President or by
the Secretary on the written request of a majority of the Board of Directors.
Notice of any special meeting of the Board shall be given at least two days
prior thereto, either in writing, or telephonically if confirmed promptly in
writing, to each director at the address shown for such director on the records
of the Corporation.

         Section 6. Waiver of Notice; Business and Purpose. Notice of any
meeting of the Board of Directors may be waived in writing signed by the person
or persons entitled to such notice either before or after the time of the
meeting. The attendance of a director at any meeting shall constitute a waiver
of notice of such meeting, except where a director attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting is not lawfully called or convened and at the beginning of the meeting
records such objection with the person acting as secretary of the meeting and
does not thereafter vote on any action taken at the meeting. Neither the
business to be transacted at, nor the purpose of, any regular or special
meeting of the Board need be specified in the notice or waiver of notice of
such meeting, unless specifically required by the Delaware Law.

         Section 7. Quorum and Manner of Acting. At all meetings of the Board
of Directors a majority of the total number of directors shall constitute a
quorum for the transaction of business. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn
the meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present. The act of a majority of the
directors present at any meeting at which there is a quorum shall be the act of
the Board


<PAGE>


of Directors, except as may be otherwise specifically provided by the Delaware
Law or by the Certificate of Incorporation. Withdrawal of directors from any
meeting shall not cause the failure of a duly constituted quorum at such
meeting. A director who is in attendance at a meeting of the Board of Directors
but who abstains from the vote on any matter shall be counted for purposes of
constituting a quorum but shall not be deemed present at such meeting for
purposes of determining the act of a majority of the directors with respect to
such vote, but shall be deemed present at such meeting for all other purposes.

         Section 8. Organization. The Chairman of the Board, if elected, shall
act as chairman at all meetings of the Board of Directors. If the Chairman of
the Board is not elected or, if elected, is not present, the Vice Chairman, if
any, or if no such Vice Chairman is present, a director chosen by a majority of
the directors present, shall act as chairman at such meeting of the Board of
Directors.

         Section 9. Committees. The Board of Directors, by resolution adopted
by a majority of the whole Board, may designate one or more directors to
constitute an Executive Committee. The Board of Directors, by resolution
adopted by a majority of the whole Board, may create one or more other
committees and appoint one or more directors to serve on such committee or
committees. Each director appointed to serve on any such committee shall serve,
unless the resolution designating the respective committee is sooner amended or
rescinded by the Board of Directors, until the next annual meeting of the Board
or until their respective successors are designated. The Board of Directors, by
resolution adopted by a majority of the whole Board, may also designate
additional directors as alternate members of any committee to serve as members
of such committee in the place and stead of any regular member or members
thereof who may be unable to attend a meeting or otherwise unavailable to act
as a member of such committee. In the absence or disqualification of a member
and all alternate members designated to serve in the place and stead of such
member, the member or members thereof present at any meeting and not
disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another director to act at the meeting in the
place and stead of such absent or disqualified member.

         The Executive Committee shall have and may exercise all the powers and
authority of the Board of Directors in the management of the business and
affairs of the Corporation between the meetings of the Board of Directors, and
any other committee may exercise the power and authority of the Board of
Directors to the extent specified by the resolution establishing such
committee, or the Certificate of Incorporation or these By-laws; provided,
however, that no committee may take any action that is expressly required by
the Delaware Law or the Certificate of Incorporation or these By-laws to be
taken by the



<PAGE>


Board of Directors and not by a committee thereof. Each committee shall keep a
record of its acts and proceedings, which shall form a part of the records of
the Corporation in the custody of the Secretary, and all actions of each
committee shall be reported to the Board of Directors at the next meeting of
the Board.

         Meetings of committees may be called at any time by the Chairman of
the Board, if any, or the chairman of the respective committee. A majority of
the members of the committee shall constitute a quorum for the transaction of
business and, except as expressly limited by this section, the act of a
majority of the members present at any meeting at which there is a quorum shall
be the act of such committee. Except as expressly provided in this section or
in the resolution designating the committee, a majority of the members of any
such committee may select its chairman, fix its rules of procedure, fix the
time and place of its meetings and specify what notice of meetings, if any,
shall be given.

         Section 10. Action without Meeting. Unless otherwise specifi cally
prohibited by the Certificate of Incorporation or these Bylaws, any action
required or permitted to be taken at any meeting of the Board of Directors or
of any committee thereof may be taken without a meeting, if all members of the
Board of Directors or such committee, as the case may be, execute a consent
thereto in writing setting forth the action so taken, and the writing or
writings are filed with the minutes of proceedings of the Board of Directors or
such committee.

         Section 11. Attendance by Telephone. Members of the Board of
Directors, or any committee thereof, may participate in and act at any meeting
of the Board of Directors, or such committee, as the case may be, through the
use of a conference telephone or other communications equipment by means of
which all persons participating in the meeting can hear each other.
Participation in such meeting shall constitute attendance and presence in
person at the meeting of the person or persons so participating.

         Section 12. Compensation. By resolution of the Board of Directors,
irrespective of any personal interest of any of the members, the directors may
be paid their reasonable expenses, if any, of attendance at each meeting of the
Board of Directors and may be paid a fixed sum of attendance at meetings or a
stated salary as directors. These payments shall not preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor.

         Section 1. Form. The shares of the Corporation shall be represented by
certificates; provided, however, the Board of Directors may provide by

stock in the Corporation, shall be signed by or in the name of the Corporation
by the Chairman or Vice Chairman of the Board or the President or a Vice
President and by the Treasurer or an Assistant Treasurer or the Secretary or an

<PAGE>

or theft of a certificate for any stock of the Corpor ation, a new certificate
of stock or uncertificated shares in place of any certificate theretofore
issued by the Corporation may be issued upon the surrender of the mutilated
certificate or, in the case of loss, destruction or theft of a certificate,
upon satisfactory proof of such loss, destruction or theft and upon such terms
as the Board of Directors may prescribe. The Board of Directors may in its
discretion require the owner of the lost, destroyed or stolen certificate, or
his legal representative, to give the Corporation a bond, in such sum and in
such form and with such surety or sureties as it may direct, to indemnify the
Corporation against any claim that may be made against it with respect to the
certificate alleged to have been lost, destroyed or stolen.

                                   ARTICLE VI
          INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS

         Section 1. Third Party Actions. The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative, or investigative, including all appeals (other than
an action, suit or proceeding by or in the right of the Corporation) by reason
of the fact that he or she is or was a director or officer of the Corpora tion
(and the Corporation, in the discretion of the Board of Directors, may so
indemnify a person by reason of the fact that he or she is or was an employee
or agent of the Corporation or is or was serving at the request of the
Corporation in any other capacity for another corporation, partnership, joint
venture, trust or other enterprise), against expenses (including attorneys'
fees), judgments, decrees, fines, penalties, and amounts paid in settlement
actually and reasonably incurred by him or her in connection with such action,
suit or proceeding if he or she acted in good faith and in a manner which he or
she reasonably believed to be in or not opposed to the best interests of the
Corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create
a presumption that the person did not act in good faith or in a manner



<PAGE>


which he or she reasonably believed to be in or not opposed to the best
interests of the Corporation and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
Notwithstanding the foregoing, the Corporation shall be required to indemnify a
director or officer in connection with an action, suit or proceeding initiated
by such person only if such action, suit or proceeding was authorized by the
Board of Directors.

         Section 2. Actions By or in the Right of the Corporation. The
Corporation shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending, or completed action or suit,
including all appeals, by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was a director
or officer of the Corporation (and the Corporation, in the discretion of the
Board of Directors, may so indemnify a person by reason of the fact that he or
she is or was an employee or agent of the Corporation or is or was serving at
the request of the Corporation in any other capacity for another corporation,
partnership, joint venture, trust or other enterprise), against expenses
(including attorneys' fees) actually and reasonably incurred by him or her in
connection with the defense or settlement of such action or suit if he or she
acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been finally adjudged to be liable to the
Corporation unless and only to the extent that the court in which such action
or suit was brought, or any other court of competent jurisdiction, shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses as such court shall deem proper.
Notwithstanding the foregoing, the Corporation shall be required to indemnify a
director or officer in connection with an action, suit or proceeding initiated
by such person only if such action, suit or proceeding was authorized by the
Board of Directors.

         Section 3. Indemnity if Successful. To the extent that a director,
officer, employee or agent of the Corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
Section 1 or 2 of this Article, or in defense of any claim, issue or matter
therein, he or she shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him or her in connection therewith.

         Section 4. Standard of Conduct. Except in a situation governed by
Section 3 of this Article, any indemnification under Section 1 or 2 of this
Article (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of
the director, officer, employee



<PAGE>


or agent is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in Section 1 or 2, as applicable, of
this Article. Such determination shall be made (i) by a majority vote of
directors acting at a meeting at which a quorum consisting of directors who
were not parties to such action, suit or proceeding is present, or (ii) if such
a quorum is not obtainable, or even if obtainable, a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or
(iii) by the stockholders. The determination required by clauses (i) and (ii)
of this Section 4 may in either event be made by written consent of the
majority required by each clause.

         Section 5. Expenses. Expenses (including attorneys' fees) of each
director and officer hereunder indemnified actually and reasonably incurred in
defending any civil, criminal, administrative or investigative action, suit or
proceeding or threat thereof shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such person to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by
the Corporation as authorized in this Article. Such expenses (including
attorneys' fees) incurred by employees and agents may be so paid upon the
receipt of the aforesaid undertaking and such terms and conditions, if any, as
the Board of Directors deems appropriate.

         Section 6. Nonexclusivity. The indemnification and advancement of
expenses provided by, or granted pursuant to, other Sections of this Article
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may now or hereafter be entitled
under any law, by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his or her official capacity and
as to action in another capacity while holding such office.

         Section 7. Insurance. The Corporation may purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another Corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him or her and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the Corporation would
have the power to indemnify him or her against such liability under the
provisions of the Delaware Law.

         Section 8. Definitions. For purposes of this Article, references to
"the Corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed
in a consolidation or merger which, if its separate existence had continued,
would have had the power and authority to indemnify any or all of its
directors,



<PAGE>


officers, employees and agents, so that any person who is or was a director,
officer, employee or agent of such constituent corporation, or is or was
serving at the request of such constituent corporation in any other capacity
for another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as such person would have had
with respect to such constituent corporation if its separate existence had
continued.

         For purposes of this Article, references to "other capacities" shall
include serving as a trustee or agent for any employee benefit plan; references
to "other enterprises" shall include employee benefit plans; references to
"fines" shall include any excise taxes assessed on a person with respect to an
employee benefit plan; and references to "serving at the request of the
Corporation" shall include any service as a director, officer, employee or
agent of the Corporation which imposes duties on, or involves services by such
director, officer, employee, or agent with respect to an employee benefit plan,
its participants, or beneficiaries. A person who acted in good faith and in a
manner he or she reasonably believed to be in the best interests of the
participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to the best interests of the Corporation"
as referred to in this Article.

         Section 9. Continuation. The indemnification and advancement of
expenses provided by, or granted pursuant to, the Delaware Law, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such person.

         Section 10. Severability. If any provision hereof is invalid or
unenforceable in any jurisdiction, the other provisions hereof shall remain in
full force and effect in such jurisdiction, and the remaining provisions hereof
shall be liberally construed to effectuate the provisions hereof, and the
invalidity of any provision hereof in any jurisdiction shall not affect the
validity or enforceability of such provision in any other jurisdiction.

         Section 11. Amendment. The right to indemnification conferred by this
Article shall be deemed to be a contract between the Corporation and each
person referred therein until amended or repealed, but no amendment to or
repeal of these provisions shall apply to or have any effect on the right to
indemnification of any person with respect to any liability or alleged
liability of such person for or with respect to any act or omission of such
person occurring prior to such amendment or repeal.

                                  ARTICLE VII

                                   AMENDMENTS

         These By-laws may be altered, amended or repealed or new By-laws may

                                                                  EXECUTION COPY

ITEM 3.
                            CN STOCK OPTION AGREEMENT

         This STOCK OPTION AGREEMENT, dated as of December 18, 1999 (this
"Agreement"), is between CANADIAN NATIONAL RAILWAY COMPANY, a Canadian
corporation ("Issuer"), and BURLINGTON NORTHERN SANTA FE CORPORATION, a Delaware
corporation ("Grantee").

                                    RECITALS

         A. The Combination Agreement. Prior to the entry into this Agreement
and prior to the grant of the Option (as defined in Section 1(a)), Issuer,
Grantee, NORTH AMERICAN RAILWAYS, INC., a Delaware corporation owned 50% by
Issuer and 50% by Grantee ("Newco"), and Western Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Newco ("Merger Sub"), have entered
into a Combination Agreement, dated as of the date of this Agreement (the
"Combination Agreement"), pursuant to which Grantee and Issuer have agreed to
effect certain transactions upon the terms and subject to the conditions set
forth in the Combination Agreement.

         B. The Stock Option Agreement. As an inducement and condition to
Grantee's willingness to enter into the Combination Agreement, and in
consideration thereof, the board of directors of Issuer has approved the grant
to Grantee of the Option pursuant to this Agreement and the acquisition of
Common Stock (as defined below) by Grantee pursuant to this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth in this Agreement and in the Combination
Agreement, the parties agree as follows:

         1. The Option. (a) Issuer hereby grants to Grantee an irrevocable
option (the "Option") to purchase, subject to the terms and conditions of this
Agreement, up to 28,895,812 fully paid and nonassessable common shares in the
capital of Issuer ("Common Stock"), of Issuer at a price per share in cash equal
to the average of the closing price of Issuer's Common Stock on the New York
Stock Exchange (as reported in The Wall Street Journal, New York City edition)
on the five trading days ending on the last trading day preceding the Notice
Date (as defined below) (the "Option Price"); provided, however, that in no
event shall the number of shares for which the Option is exercisable exceed
12.5% of the shares of Common Stock issued and outstanding at the time of
exercise (giving effect to the shares of Common Stock issued or issuable under
the Option) (the "Maximum Applicable Percentage"). The number of shares of
Common Stock purchasable upon exercise of the Option are subject to adjustment
as set forth in this Agreement.
<PAGE>

         (b) In the event that any additional shares of Common Stock are issued
or otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement), the aggregate number of shares of Common Stock
purchasable upon exercise of the Option (inclusive of shares, if any, previously
purchased upon exercise of the Option) shall automatically be increased (without
any further action on the part of Issuer or Grantee being necessary) so that,
after such issuance, it equals the Maximum Applicable Percentage. No such
increase shall affect the Option Price.

         2. Exercise; Closing. (a) Manner of Exercise; Termination. Grantee or
any other person that shall become a holder of all or part of the Option in
accordance with the terms of this Agreement (each such person being sometimes
referred to in this Agreement as the "Holder") may exercise the Option, in whole
or in part, by delivering a written notice thereof as provided in Section 2(d)
within 18 months following the occurrence of a Triggering Event (as defined in
Section 2(b)) unless prior to such Triggering Event either the Merger Effective
Time or the Arrangement Effective Time (as such terms are defined in the
Combination Agreement) shall have occurred or the Option shall have terminated
in accordance with the following sentence. The Option shall terminate upon any
of (i) the occurrence of either the Merger Effective Time or the Arrangement
Effective Time, (ii) if no notice pursuant to the preceding sentence has been
delivered prior thereto, the close of business on the day 18 months after the
date that Grantee becomes entitled to receive the CN Termination Fee (as defined
in the Combination Agreement) under Section 10.4(c) of the Combination
Agreement, (iii) the performance of the BNSF Stock Option Agreement (as defined
in the Combination Agreement) by Grantee or the right of Issuer to purchase
shares of Grantee's common stock upon exercise of the option granted thereunder
shall have been finally enjoined or held invalid by a court of competent
jurisdiction or (iv) the execution of or the written agreement to enter into an
agreement or series of agreements relating to a Business Combination Transaction
(as defined below) with such Holder; provided, however, that in the event that
any portion of the Option is held by any other person other than the Grantee in
accordance with the terms of this Agreement, any termination pursuant to clause
(iv) above shall only apply to such portion of the Option held by such Holder
and shall not effect that portion of the Option held by the Grantee or such
other persons, as the case may be. A "Business Combination Transaction" shall
mean (i) a consolidation, exchange of shares or merger of a Holder with any
Person and, in the case of a merger, in which the Holder shall not be the
continuing or surviving corporation, (ii) any transaction (including, without
limitation, a consolidation, exchange of shares or merger) in which the Holder
shall be the continuing or surviving corporation but the then outstanding shares
of capital stock of the Holder shall be changed into or exchanged for stock or
other securities of the Holder or any other Person or cash or any other property
or the capital stock of such Holder outstanding immediately before such
transaction shall after such transaction represent less than 50% of the common
shares and common share equivalents of such Holder outstanding immediately after
the transaction or (iii) a sale, lease or other transfer of all or substantially
all the assets of the Holder to any Person.

         (b) Triggering Event. A "Triggering Event" shall have occurred if the
Combination Agreement is terminated and Grantee shall have become entitled to
receive the CN Termination Fee pursuant to Section 10.4(c) of the Combination
Agreement.

<PAGE>

         (c) Notice of Triggering Event by Issuer. Issuer shall notify Grantee
promptly in writing of the occurrence of any Triggering Event, it being
understood that the giving of such notice by Issuer shall not be a condition to
the right of the Holder to exercise the Option.

         (d) Notice of Exercise by Grantee. If the Holder shall be entitled to
and wishes to exercise the Option, it shall send to Issuer a written notice (the
date of which is referred to in this Agreement as the "Notice Date") specifying
(i) the total number of shares that the Holder will purchase pursuant to such
exercise and (ii) a place and date (a "Closing Date") not earlier than three
business days nor later than 30 business days from the Notice Date for the
closing of such purchase (a "Closing"); provided, that if the Closing cannot be
effected by reason of the application of any law or regulation, (x) the Holder
or Issuer, as required, promptly after the giving of such notice shall file the
required notice, report, filing or application for approval and shall
expeditiously process the same and (y) the Closing Date shall be extended to not
later than the tenth business day following the expiration or termination of the
restriction imposed by such law. Each of the Holder and the Issuer agrees to use
its reasonable best efforts to cooperate with and provide information to Issuer
or Holder, as the case may be, for the purpose of any required notice, report,
filing or application for approval.

         (e) Payment of Purchase Price. At each Closing, the Holder shall pay to
Issuer the aggregate purchase price for the shares of Common Stock purchased
pursuant to the exercise of the Option in immediately available funds by a wire
transfer to a bank account designated by Issuer; provided, that failure or
refusal of Issuer to designate such a bank account shall not preclude the Holder
from exercising the Option, in whole or in part.

         (f) Delivery of Common Stock. At such Closing, simultaneously with the
payment of the purchase price by the Holder, Issuer shall deliver to the Holder
a certificate or certificates representing the number of shares of Common Stock
purchased by the Holder and, if the Option shall be exercised in part only, a
new Option evidencing the rights of the Holder to purchase the balance (as
adjusted pursuant to Section 1(b)) of the shares of Common Stock then
purchasable under this Agreement.

         (g) Restrictive Legend. Certificates for Common Stock delivered at a
Closing shall be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate is
         subject to resale restrictions arising under the Securities Act of
         1933, as amended, and the applicable Canadian securities laws."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if the Holder shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission, or a written opinion of counsel, in form and substance
reasonably satisfactory to Issuer, to the effect that such legend is not
required for purposes of either the Securities Act of 1933, as amended (the
"Securities Act") or the applicable Canadian securities laws. In addition, such
certificates shall bear any other legend as may be required by applicable law.
<PAGE>

         (h) Ownership of Record; Tender of Purchase Price; Expenses. Upon the
giving by the Holder to Issuer of a written notice of exercise referred to in
Section 2(d) and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not have been delivered to the
Holder. Issuer shall pay all expenses, and any and all United States and
Canadian federal, provincial, territorial, state and local taxes and other
charges that may be payable in connection with the preparation, issue and
delivery of stock certificates under this Section 2 in the name of the Holder or
its assignee, transferee or designee.

         (i) Effect of Statutory or Regulatory Restraints on Exercise. To the
extent that, upon or following the giving by the Holder to Issuer of a written
notice of exercise referred to in Section 2(d), Issuer is prohibited under
applicable law or regulation from delivering to the Holder a certificate or
certificates representing the number of shares of Common Stock purchased by the
Holder, Issuer shall immediately so notify the Holder in writing and thereafter
deliver or cause to be delivered, from time to time, to the Holder the portion
of the Option Shares that Issuer is no longer prohibited from delivering, within
two business days after the date on which it is no longer so prohibited;
provided, however, that upon notification by Issuer in writing of such
prohibition, the Holder may, at any time after receipt of such notification from
Issuer, revoke in writing its exercise notice, whether in whole or to the extent
of the prohibition, whereupon, in the latter case, Issuer shall promptly (i)
deliver to the Holder that portion of the Option Shares that Issuer is not
prohibited from delivering pursuant to the time periods set forth in Section
2(d); and (ii) deliver to the Holder, as appropriate, with respect to the
Option, a new Stock Option Agreement evidencing the right of the Holder to
purchase that number of shares of Common Stock for which the surrendered Stock
Option Agreement was exercisable at the time of giving the written notice of
exercise referred to in Section 2(d). Notwithstanding anything to the contrary
in this Agreement, the period for exercise of rights related to the Option set
forth in Section 2(a) shall be extended, at the request of Holder, for a period
not to exceed 180 days from the date that the Option would have terminated
pursuant to Section 2(a) hereof or such shorter period necessary to permit the
delivery of all the Option Shares subject to the exercise notice.

         (j) Conditions to Exercise. The obligation of the Issuer to effect the
Closing shall be subject to the following conditions:

                  (a)      all regulatory approvals required of the Issuer in
                           connection with the issuance of the Option Shares
                           hereunder shall have been obtained, including that
                           the grant of the Option and the issuance of the
                           Option Shares shall have been approved by The Toronto
                           Stock Exchange; and

                  (b)      the issuance of the Option Shares at the Closing
                           shall not be prohibited by any law, regulation,
                           injunction or order of any Governmental Entity (as
                           defined in the Combination Agreement).
<PAGE>

         (k) Waiver of Voting Rights. The Grantee agrees that it shall have no
voting rights, and shall not exercise or permit to be exercised any voting
rights in any circumstance, in respect of the Option or the Common Stock
purchasable under the Option unless, until, and only to the extent that the
Option has been exercised and Common Stock has actually been purchased
thereunder.

         3. Covenants of Issuer. In addition to its other agreements and
covenants in this Agreement, Issuer agrees:

                  (a) Shares Reserved for Issuance. It will maintain, free from
         preemptive rights, sufficient authorized but unissued shares of Common
         Stock to issue the appropriate number of shares of Common Stock
         pursuant to the terms of this Agreement so that the Option may be fully
         exercised without additional authorization of Common Stock after giving
         effect to all other options, warrants, convertible securities and other
         rights of third parties to purchase shares of Common Stock from Issuer.

                  (b) No Avoidance. It will not avoid or seek to avoid (whether
         by amendment of its constitutive documents or through reorganization,
         consolidation, merger, issuance of rights, dissolution or sale of
         assets, or by any other voluntary act) the observance or performance of
         any of the covenants, agreements or conditions to be observed or
         performed under this Agreement by Issuer.

                  (c) Further Assurances. After the date of this Agreement, it
         will promptly take all actions as may from time to time be required
         (including (i) seeking any necessary governmental approval, exemption
         or other authorization, (ii) complying with all applicable premerger
         notification, reporting and waiting period requirements under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and
         (iii) in the event that prior notice, report, filing or approval with
         respect to any Governmental Entity is necessary under any applicable
         foreign, United States or Canadian federal, provincial, territorial,
         state or local law before the Option may be exercised, cooperating
         fully with the Holder in preparing and processing the required
         applications or notices) in order to permit each Holder to exercise the
         Option and purchase shares of Common Stock pursuant to such exercise
         and to take all action necessary to protect the rights of the Holder
         against dilution.

                  (d) Stock Exchange Listing. It will use its reasonable best
         efforts to cause the shares of Common Stock to be issued pursuant to
         the Option to be approved for listing (to the extent they are not
         already listed) on all securities exchanges on which shares of Common
         Stock of the Issuer are then listed, subject to official notice of
         issuance.

         4. Representations and Warranties of Issuer. Issuer represents and
warrants to Grantee as follows:

                  (a) Shares Reserved for Issuance; Capital Stock. Issuer has
         taken all necessary corporate action to authorize and reserve, free
         from preemptive rights, and
<PAGE>

         permit it to issue, sufficient authorized but unissued shares of
         Common Stock so that the Option may be fully exercised without
         additional authorization of Common Stock after giving effect to all
         other options, warrants, convertible securities and other rights of
         third parties to purchase shares of Common Stock from Issuer, and all
         such shares, upon issuance pursuant to the Option, will be duly
         authorized, validly issued, fully paid and nonassessable, and will be
         delivered free and clear of all claims, liens, encumbrances, and
         security interests (other than those created by this Agreement) and
         not subject to any preemptive rights.

         5. Adjustments. In addition to the adjustment to the total number of
shares of Common Stock purchasable upon exercise of the Option pursuant to
Section 1(b), the total number of shares of Common Stock purchasable upon the
exercise of the Option shall be subject to adjustment from time to time as
follows:

                  (a) In the event of any change in the outstanding shares of
         Common Stock by reason of stock dividends, split-ups, mergers,
         recapitalizations, combinations, subdivisions, conversions, exchanges
         of shares or the like, the type and number of shares of Common Stock
         purchasable upon exercise of the Option, shall be appropriately
         adjusted, and proper provision shall be made in the agreements
         governing any such transaction, so that (i) any Holder shall receive
         upon exercise of the Option the number and class of shares, other
         securities, property or cash that such Holder would have received in
         respect of the shares of Common Stock purchasable upon exercise of the
         Option if the Option had been exercised and such shares of Common Stock
         had been issued to such Holder immediately prior to such event or the
         record date therefor, as applicable and (ii) in the event any
         additional shares of Common Stock are to be issued or otherwise become
         outstanding as a result of any such change (other than pursuant to an
         exercise of the Option), the number of shares of Common Stock
         purchasable upon exercise of the Option shall be increased so that,
         after such issuance and together with shares of Common Stock previously
         issued pursuant to the exercise of the Option (as adjusted on account
         of any of the foregoing changes in the Common Stock), the number of
         shares so purchasable equals the Maximum Applicable Percentage of the
         number of shares of Common Stock issued and outstanding immediately
         after the consummation of such change. If any such change in the
         outstanding shares of Common Stock occurs at any time on or after the
         first trading day included in the calculation of the Option Price and
         prior to the Closing, equitable adjustment shall be made to the Option
         Price to reflect the effect of such change.

                  (b) Without limiting the parties' relative rights and
         obligations under the Combination Agreement, in the event that Issuer
         enters into an agreement or arrangement (i) to consolidate with or
         merge into any person, other than Grantee or one of its subsidiaries,
         and Issuer will not be the continuing or surviving corporation in such
         consolidation or merger, (ii) to permit any person, other than Grantee
         or one of its subsidiaries, to merge into Issuer and Issuer will be the
         continuing or surviving corporation, but in connection with such
         merger, the shares of Common Stock outstanding immediately prior to the
         consummation of such merger will be changed into
<PAGE>

         or exchanged for stock or other securities of Issuer or any other
         person or cash or any other property, or the shares of Common Stock
         outstanding immediately prior to the consummation of such merger will,
         after such merger, represent less than 50% of the outstanding voting
         securities of the merged company, or (iii) to sell or otherwise
         transfer all or substantially all of its assets to any person, other
         than Grantee or one of its subsidiaries, then, and in each such case,
         the agreement governing such transaction will make proper provision so
         that the Option will, upon the consummation of any such transaction
         and upon the terms and conditions set forth herein, be converted into,
         or exchanged for, an option with identical terms appropriately
         adjusted to acquire the number and class of shares or other securities
         or property that Grantee would have received in respect of the Common
         Stock if the Option had been exercised immediately prior to such
         consolidation, merger, sale or transfer or the record date therefor,
         as applicable and make any other necessary adjustments.

         6. Registration. (a) Upon the occurrence of a Triggering Event, Issuer
shall, at the request of a Holder, as promptly as practicable prepare, file and
keep current a shelf registration statement under the Securities Act covering
any or all shares issued and issuable pursuant to the Option and shall use its
best efforts to cause such registration statement to become and remain effective
for such period as may be reasonably necessary to permit the sale or other
disposition of any shares of Common Stock issued upon total or partial exercise
of the Option ("Option Shares") in accordance with any plan of disposition
requested by such Holder; provided, however, that Issuer may suspend filing of
or maintaining the effectiveness of a registration statement relating to a
registration request by a Holder under this Section 6 for a period of time (not
in excess of 60 days in the aggregate) if in its judgment such filing of such
registration statement or the maintenance of its effectiveness would require the
disclosure of nonpublic information that Issuer has a good faith business
purpose for preserving as confidential. Subject to the foregoing, Issuer will
use its reasonable best efforts to cause such registration statement to become
effective as soon as practicable. In connection with any such registration,
Issuer and the Holder requesting such registration shall provide each other with
representations, warranties, indemnities and other agreements customarily given
in connection with such registrations. If requested by such Holder in connection
with such registration, Issuer shall become a party to any underwriting
agreement relating to the sale of such shares, but only to the extent of
obligating Issuer in respect of representations, warranties, indemnities,
contribution and other agreements customarily made by issuers in such
underwriting agreements.

         (b) In the event that such Holder so requests, the closing of the sale
or other disposition of the Common Stock or other securities pursuant to a
registration statement filed pursuant to Section 6(a) shall occur substantially
simultaneously with the exercise of the Option.

         (c) Any registration statement prepared and filed under this Section 6
and any sale covered thereby, will be at Issuer's expense except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of the Holder's counsel related thereto. In connection with any
registration pursuant to this Section 6, Issuer and such Holder will provide
each other and any underwriter of the offering with customary representations,
warranties, covenants, indemnification, and contribution in connection with such
registration.
<PAGE>

         7. Extension of Exercise Periods. The periods for exercise of certain
rights under Section 2 shall be extended in each such case at the request of the
Holder to the extent necessary to avoid liability by the Holder under Section
16(b) of the Securities Exchange Act of 1934, as amended ("Section 16(b)"), by
reason of such exercise.

         8. Assignment. Neither party may assign any of its rights or
obligations under this Agreement or the Option to any other person without the
express written consent of the other party. Any attempted assignment in
contravention of the preceding sentence shall be null and void.

         9. Filings; Other Actions. The parties hereto will use their reasonable
best efforts to make all filings with, and to obtain consents of, all third
parties and governmental authorities necessary for the consummation of the
transactions contemplated by this Agreement.

         10. Specific Performance. The parties acknowledge that damages would be
an inadequate remedy for a breach of this Agreement by either party and that the
obligations of the parties shall be specifically enforceable through injunctive
or other equitable relief.

         11. Severability. The provisions of this Agreement, the Combination
Agreement and any other agreement contemplated by the Combination Agreement
shall be deemed severable and the invalidity or unenforceability of any
provision of this Agreement, the Combination Agreement or any other agreement
contemplated by the Combination Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement or any provisions of
such other agreement. Without limiting the generality of the foregoing, the
invalidity or unenforceability of any provision of any such other agreement
shall not affect the validity or enforceability of any provision of this
Agreement. If any provision of this Agreement or any such other agreement or the
application thereof to any Person or any circumstance, is invalid or
unenforceable, (i) a suitable and equitable provision shall be substituted
therefor in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid or unenforceable provision and (ii) the
remainder of this Agreement or any such other agreement and the application of
such provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction. If for any reason a Governmental Entity
determines that the Holder is not permitted to acquire the full number of shares
of Common Stock provided in Section 1(a) of this Agreement (as adjusted pursuant
to Sections 1(b) and 5 of this Agreement), it is the express intention of Issuer
to allow the Holder to acquire or to require Issuer to repurchase such lesser
number of shares as may be permissible, without any amendment or modification of
this Agreement or any other agreement executed or to be executed in connection
herewith.

         12. Notices. Notices, requests, instructions or other documents to be
given under this Agreement shall be in writing and shall be deemed given, (i)
when sent, if sent by facsimile, provided that a copy of the facsimile is
promptly sent by U.S. mail and confirmation of receipt has been delivered (ii)
when delivered, if delivered personally to the intended recipient, and (iii)


<PAGE>

one business day later, if sent by overnight delivery via an international
courier service and, in each case at the respective addresses of the parties set
forth in the Combination Agreement.

         13. Expenses. Except as otherwise expressly provided in this Agreement
or in the Combination Agreement, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated by this Agreement shall be
paid by the party incurring such expense, including fees and expenses of its own
financial consultants, investment bankers, accountants, and counsel.

         14. Entire Agreement. This Agreement, the Confidentiality Agreement (as
defined in the Combination Agreement) and the Combination Agreement (including
any other exhibits thereto and the ancillary agreements contemplated thereby)
constitute the entire agreement, and supersede all other prior agreements,
understandings, representations and warranties, both written and oral, between
the parties, with respect to the subject matter of this Agreement. The terms and
conditions of this Agreement shall inure to the benefit of and be binding upon
the parties and their respective successors and permitted assigns. Nothing in
this Agreement is intended to confer upon any person or entity, other than the
parties to this Agreement, and their respective successors and permitted
assigns, any rights or remedies under this Agreement.

         15. Governing Law and Venue; Waiver of Jury Trial.

         (a) This Agreement shall be deemed to be made in and in all respects
shall be interpreted, construed and governed by and in accordance with the laws
of the State of New York without regard to the conflict of law principles
thereof. The parties hereby irrevocably and unconditionally consent to submit to
the exclusive jurisdiction of both the courts of the State of Delaware and of
the United States of America located in Wilmington, Delaware (the "Delaware
Courts") and the Quebec Superior Court located in Montreal, Quebec (the "Quebec
Court") for any litigation arising out of or relating to this Agreement and the
transactions contemplated by this Agreement, waive any objection to the laying
of venue of any such litigation in the Delaware Courts or the Quebec Court and
agree not to plead or claim in any Delaware Court or the Quebec Court that such
litigation brought therein has been brought in an inconvenient forum; provided,
however, that the parties agree that any proceedings in the Quebec Court arising
out of or relating to this Agreement and the transactions contemplated by this
Agreement shall be conducted in English and all written documents relating to
any such proceedings shall be written in English.

         (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY
RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN THE
EVENT OF


<PAGE>

LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS
AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS
WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 15.

         16. U.S. Dollars. All amounts paid or payable hereunder, and all prices
referenced hereunder, shall be in United States Dollars.

         17. Captions. The Section and paragraph captions in this Agreement are
for convenience of reference only, do not constitute part of this Agreement and
shall not be deemed to limit or otherwise affect any of the provisions of this
Agreement.

ITEM 4.

                          BNSF STOCK OPTION AGREEMENT

         This STOCK OPTION AGREEMENT, dated as of December 18, 1999 (this
"Agreement"), is between BURLINGTON NORTHERN SANTA FE CORPORATION, a Delaware
corporation ("Issuer"), and CANADIAN NATIONAL RAILWAY COMPANY, a Canadian
corporation ("Grantee").


                                   RECITALS

         A. The Combination Agreement. Prior to the entry into this Agreement
and prior to the grant of the Option (as defined in Section 1(a)), Issuer,
Grantee, NORTH AMERICAN RAILWAYS, INC., a Delaware corporation owned 50% by
Issuer and 50% by Grantee ("Newco"), and Western Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Newco ("Merger Sub"), have
entered into a Combination Agreement, dated as of the date of this Agreement
(the "Combination Agreement"), pursuant to which Grantee and Issuer have
agreed to effect certain transactions upon the terms and subject to the
conditions set forth in the Combination Agreement.

         B. The Stock Option Agreement. As an inducement and condition to
Grantee's willingness to enter into the Combination Agreement, and in
consideration thereof, the board of directors of Issuer has approved the grant
to Grantee of the Option pursuant to this Agreement and the acquisition of
Common Stock (as defined below) by Grantee pursuant to this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth in this Agreement and in the Combination
Agreement, the parties agree as follows:

         1. The Option. (a) Issuer hereby grants to Grantee an irrevocable
option (the "Option") to purchase, subject to the terms and conditions of this
Agreement, up to 64,992,261 fully paid and nonassessable shares of common
stock, par value $0.01 per share ("Common Stock"), of Issuer at a price per
share in cash equal to the average of the closing price of Issuer's Common
Stock on the New York Stock Exchange (as reported in The Wall Street Journal,
New York City edition) on the five trading days ending on the last trading day
preceding the Notice Date (as defined below) (the "Option Price"); provided,
however, that in no event shall the number of shares for which the Option is
exercisable exceed 12.5% of the shares of Common Stock issued and outstanding
at the time of exercise (giving effect to the shares of Common Stock issued or
issuable under the Option) (the "Maximum Applicable Percentage"). The number
of shares of Common Stock purchasable upon exercise of the Option are subject
to adjustment as set forth in this Agreement.


<PAGE>


         (b) In the event that any additional shares of Common Stock are
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement), the aggregate number of shares of Common
Stock purchasable upon exercise of the Option (inclusive of shares, if any,
previously purchased upon exercise of the Option) shall automatically be
increased (without any further action on the part of Issuer or Grantee being
necessary) so that, after such issuance, it equals the Maximum Applicable
Percentage. No such increase shall affect the Option Price.

         2. Exercise; Closing. (a) Manner of Exercise; Termination. Grantee or
any other person that shall become a holder of all or part of the Option in
accordance with the terms of this Agreement (each such person being sometimes
referred to in this Agreement as the "Holder") may exercise the Option, in
whole or in part, by delivering a written notice thereof as provided in
Section 2(d) within 18 months following the occurrence of a Triggering Event
(as defined in Section 2(b)) unless prior to such Triggering Event either the
Merger Effective Time or the Arrangement Effective Time (as such terms are
defined in the Combination Agreement) shall have occurred or the Option shall
have terminated in accordance with the following sentence. The Option shall
terminate upon any of (i) the occurrence of either the Merger Effective Time
or the Arrangement Effective Time, (ii) if no notice pursuant to the preceding
sentence has been delivered prior thereto, the close of business on the day 18
months after the date that Grantee becomes entitled to receive the BNSF
Termination Fee (as defined in the Combination Agreement) under Section
10.4(b) of the Combination Agreement, (iii) the performance of the CN Stock
Option Agreement (as defined in the Combination Agreement) by Grantee or the
right of Issuer to purchase shares of Grantee's common stock upon exercise of
the option granted thereunder shall have been finally enjoined or held invalid
by a court of competent jurisdiction or (iv) the execution of or the written
agreement to enter into an agreement or series of agreements relating to a
Business Combination Transaction (as defined below) with such Holder;
provided, however, that in the event that any portion of the Option is held by
any other person other than the Grantee in accordance with the terms of this
Agreement, any termination pursuant to clause (iv) above shall only apply to
such portion of the Option held by such Holder and shall not effect that
portion of the Option held by the Grantee or such other persons, as the case
may be. A "Business Combination Transaction" shall mean (i) a consolidation,
exchange of shares or merger of a Holder with any Person and, in the case of a
merger, in which the Holder shall not be the continuing or surviving
corporation, (ii) any transaction (including, without limitation, a
consolidation, exchange of shares or merger) in which the Holder shall be the
continuing or surviving corporation but the then outstanding shares of capital
stock of the Holder shall be changed into or exchanged for stock or other
securities of the Holder or any other Person or cash or any other property or
the capital stock of such Holder outstanding immediately before such
transaction shall after such transaction represent less than 50% of the common
shares and common share equivalents of such Holder outstanding immediately
after the transaction or (iii) a sale, lease or other transfer of all or
substantially all the assets of the Holder to any Person.

         (b) Triggering Event. A "Triggering Event" shall have occurred if the
Combination Agreement is terminated and Grantee shall have become entitled to
receive the BNSF Termination Fee pursuant to Section 10.4(b) of the
Combination Agreement.


<PAGE>


         (c) Notice of Triggering Event by Issuer. Issuer shall notify Grantee
promptly in writing of the occurrence of any Triggering Event, it being
understood that the giving of such notice by Issuer shall not be a condition
to the right of the Holder to exercise the Option.

         (d) Notice of Exercise by Grantee. If the Holder shall be entitled to
and wishes to exercise the Option, it shall send to Issuer a written notice
(the date of which is referred to in this Agreement as the "Notice Date")
specifying (i) the total number of shares that the Holder will purchase
pursuant to such exercise and (ii) a place and date (a "Closing Date") not
earlier than three business days nor later than 30 business days from the
Notice Date for the closing of such purchase (a "Closing"); provided, that if
the Closing cannot be effected by reason of the application of any law or
regulation, (x) the Holder or Issuer, as required, promptly after the giving
of such notice shall file the required notice, report, filing or application
for approval and shall expeditiously process the same and (y) the Closing Date
shall be extended to not later than the tenth business day following the
expiration or termination of the restriction imposed by such law. Each of the
Holder and the Issuer agrees to use its reasonable best efforts to cooperate
with and provide information to Issuer or Holder, as the case may be, for the
purpose of any required notice, report, filing or application for approval.

         (e) Payment of Purchase Price. At each Closing, the Holder shall pay
to Issuer the aggregate purchase price for the shares of Common Stock
purchased pursuant to the exercise of the Option in immediately available
funds by a wire transfer to a bank account designated by Issuer; provided,
that failure or refusal of Issuer to designate such a bank account shall not
preclude the Holder from exercising the Option, in whole or in part.

         (f) Delivery of Common Stock. At such Closing, simultaneously with
the payment of the purchase price by the Holder, Issuer shall deliver to the
Holder a certificate or certificates representing the number of shares of
Common Stock purchased by the Holder and, if the Option shall be exercised in
part only, a new Option evidencing the rights of the Holder to purchase the
balance (as adjusted pursuant to Section 1(b)) of the shares of Common Stock
then purchasable under this Agreement.

         (g) Restrictive Legend. Certificates for Common Stock delivered at a
Closing shall be endorsed with a restrictive legend that shall read
substantially as follows:

                  "The transfer of the shares represented by this certificate
         is subject to resale restrictions arising under the Securities Act of
         1933, as amended."

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if the Holder shall have
delivered to Issuer a copy of a letter from the staff of the Securities and
Exchange Commission, or a written opinion of counsel, in form and substance
reasonably satisfactory to Issuer, to the effect that such legend is not
required for purposes of the Securities Act of 1933, as amended (the
"Securities Act"). In addition, such certificates shall bear any other legend
as may be required by applicable law.

         (h) Ownership of Record; Tender of Purchase Price; Expenses. Upon the
giving by the Holder to Issuer of a written notice of exercise referred to in
Section 2(d) and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not have been delivered to the
Holder. Issuer shall pay all expenses, and any and all United States and
Canadian federal, provincial, territorial, state and local taxes and other
charges that may be payable in connection with the preparation, issue and
delivery of stock certificates under this Section 2 in the name of the Holder
or its assignee, transferee or designee.

         (i) Effect of Statutory or Regulatory Restraints on Exercise. To the
extent that, upon or following the giving by the Holder to Issuer of a written
notice of exercise referred to in Section 2(d), Issuer is prohibited under
applicable law or regulation from delivering to the Holder a certificate or
certificates representing the number of shares of Common Stock purchased by
the Holder, Issuer shall immediately so notify the Holder in writing and
thereafter deliver or cause to be delivered, from time to time, to the Holder
the portion of the Option Shares that Issuer is no longer prohibited from
delivering, within two business days after the date on which it is no longer
so prohibited; provided, however, that upon notification by Issuer in writing
of such prohibition, the Holder may, at any time after receipt of such
notification from Issuer, revoke in writing its exercise notice, whether in
whole or to the extent of the prohibition, whereupon, in the latter case,
Issuer shall promptly (i) deliver to the Holder that portion of the Option
Shares that Issuer is not prohibited from delivering pursuant to the time
periods set forth in Section 2(d); and (ii) deliver to the Holder, as
appropriate, with respect to the Option, a new Stock Option Agreement
evidencing the right of the Holder to purchase that number of shares of Common
Stock for which the surrendered Stock Option Agreement was exercisable at the
time of giving the written notice of exercise referred to in Section 2(d).
Notwithstanding anything to the contrary in this Agreement, the period for
exercise of rights related to the Option set forth in Section 2(a) shall be
extended, at the request of Holder, for a period not to exceed 180 days from
the date that the Option would have terminated pursuant to Section 2(a) hereof
or such shorter period necessary to permit the delivery of all the Option
Shares subject to the exercise notice.

         (j) Conditions to Exercise. The obligation of the Issuer to effect
the Closing shall be subject to the condition that the issuance of the Option
Shares at the Closing shall not be prohibited by any law, regulation,
injunction or order of any Governmental Entity (as defined in the Combination
Agreement).

         (k) Waiver of Voting Rights. The Grantee agrees that it shall have no
voting rights, and shall not exercise or permit to be exercised any voting
rights in any circumstance, in respect of the Option or the Common Stock
purchasable under the Option unless, until, and only to the extent that the
Option has been exercised and Common Stock has been actually purchased
thereunder.

         3. Covenants of Issuer. In addition to its other agreements and
covenants in this Agreement, Issuer agrees:


<PAGE>


                  (a) Shares Reserved for Issuance. It will maintain, free
         from preemptive rights, sufficient authorized but unissued shares of
         Common Stock to issue the appropriate number of shares of Common
         Stock pursuant to the terms of this Agreement so that the Option may
         be fully exercised without additional authorization of Common Stock
         after giving effect to all other options, warrants, convertible
         securities and other rights of third parties to purchase shares of
         Common Stock from Issuer.

                  (b) No Avoidance. It will not avoid or seek to avoid
         (whether by amendment of its constitutive documents or through
         reorganization, consolidation, merger, issuance of rights,
         dissolution or sale of assets, or by any other voluntary act) the
         observance or performance of any of the covenants, agreements or
         conditions to be observed or performed under this Agreement by
         Issuer.

                  (c) Further Assurances. After the date of this Agreement, it
         will promptly take all actions as may from time to time be required
         (including (i) seeking any necessary governmental approval, exemption
         or other authorization, (ii) complying with all applicable premerger
         notification, reporting and waiting period requirements under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and
         (iii) in the event that prior notice, report, filing or approval with
         respect to any Governmental Entity is necessary under any applicable
         foreign, United States or Canadian federal, provincial, territorial,
         state or local law before the Option may be exercised, cooperating
         fully with the Holder in preparing and processing the required
         applications or notices) in order to permit each Holder to exercise
         the Option and purchase shares of Common Stock pursuant to such
         exercise and to take all action necessary to protect the rights of
         the Holder against dilution.

                  (d) Stock Exchange Listing. It will use its reasonable best
         efforts to cause the shares of Common Stock to be issued pursuant to
         the Option to be approved for listing (to the extent they are not
         already listed) on all securities exchanges on which shares of Common
         Stock of the Issuer are then listed, subject to official notice of
         issuance.

         4. Representations and Warranties of Issuer. Issuer represents and
warrants to Grantee as follows:

                  (a) Shares Reserved for Issuance; Capital Stock. Issuer has
         taken all necessary corporate action to authorize and reserve, free
         from preemptive rights, and permit it to issue, sufficient authorized
         but unissued shares of Common Stock so that the Option may be fully
         exercised without additional authorization of Common Stock after
         giving effect to all other options, warrants, convertible securities
         and other rights of third parties to purchase shares of Common Stock
         from Issuer, and all such shares, upon issuance pursuant to the
         Option, will be duly authorized, validly issued, fully paid and
         nonassessable, and will be delivered free and clear of all claims,
         liens, encumbrances, and security interests (other than those created
         by this Agreement) and not subject to any preemptive rights.


<PAGE>


         5. Adjustments. In addition to the adjustment to the total number of
shares of Common Stock purchasable upon exercise of the Option pursuant to
Section 1(b), the total number of shares of Common Stock purchasable upon the
exercise of the Option shall be subject to adjustment from time to time as
follows:

                  (a) In the event of any change in the outstanding shares of
         Common Stock by reason of stock dividends, split-ups, mergers,
         recapitalizations, combinations, subdivisions, conversions, exchanges
         of shares or the like, the type and number of shares of Common Stock
         purchasable upon exercise of the Option, shall be appropriately
         adjusted, and proper provision shall be made in the agreements
         governing any such transaction, so that (i) any Holder shall receive
         upon exercise of the Option the number and class of shares, other
         securities, property or cash that such Holder would have received in
         respect of the shares of Common Stock purchasable upon exercise of
         the Option if the Option had been exercised and such shares of Common
         Stock had been issued to such Holder immediately prior to such event
         or the record date therefor, as applicable and (ii) in the event any
         additional shares of Common Stock are to be issued or otherwise
         become outstanding as a result of any such change (other than
         pursuant to an exercise of the Option), the number of shares of
         Common Stock purchasable upon exercise of the Option shall be
         increased so that, after such issuance and together with shares of
         Common Stock previously issued pursuant to the exercise of the Option
         (as adjusted on account of any of the foregoing changes in the Common
         Stock), the number of shares so purchasable equals the Maximum
         Applicable Percentage of the number of shares of Common Stock issued
         and outstanding immediately after the consummation of such change. If
         any such change in the outstanding shares of Common Stock occurs at
         any time on or after the first trading day included in the
         calculation of the Option Price and prior to the Closing, equitable
         adjustment shall be made to the Option Price to reflect the effect of
         such changes.

                  (b) Without limiting the parties' relative rights and
         obligations under the Combination Agreement, in the event that Issuer
         enters into an agreement or arrangement (i) to consolidate with or
         merge into any person, other than Grantee or one of its subsidiaries,
         and Issuer will not be the continuing or surviving corporation in
         such consolidation or merger, (ii) to permit any person, other than
         Grantee or one of its subsidiaries, to merge into Issuer and Issuer
         will be the continuing or surviving corporation, but in connection
         with such merger, the shares of Common Stock outstanding immediately
         prior to the consummation of such merger will be changed into or
         exchanged for stock or other securities of Issuer or any other person
         or cash or any other property, or the shares of Common Stock
         outstanding immediately prior to the consummation of such merger
         will, after such merger, represent less than 50% of the outstanding
         voting securities of the merged company, or (iii) to sell or
         otherwise transfer all or substantially all of its assets to any
         person, other than Grantee or one of its subsidiaries, then, and in
         each such case, the agreement governing such transaction will make
         proper provision so that the Option will, upon the consummation of
         any such transaction and upon the terms and conditions set forth
         herein, be converted into, or


<PAGE>


         exchanged for, an option with identical terms appropriately adjusted
         to acquire the number and class of shares or other securities or
         property that Grantee would have received in respect of the Common
         Stock if the Option had been exercised immediately prior to such
         consolidation, merger, sale or transfer or the record date therefor,
         as applicable and make any other necessary adjustments.

         6. Registration. (a) Upon the occurrence of a Triggering Event,
Issuer shall, at the request of a Holder, as promptly as practicable prepare,
file and keep current a shelf registration statement under the Securities Act
covering any or all shares issued and issuable pursuant to the Option and
shall use its best efforts to cause such registration statement to become and
remain effective for such period as may be reasonably necessary to permit the
sale or other disposition of any shares of Common Stock issued upon total or
partial exercise of the Option ("Option Shares") in accordance with any plan
of disposition requested by such Holder; provided, however, that Issuer may
suspend filing of or maintaining the effectiveness of a registration statement
relating to a registration request by a Holder under this Section 6 for a
period of time (not in excess of 60 days in the aggregate) if in its judgment
such filing of such registration statement or the maintenance of its
effectiveness would require the disclosure of nonpublic information that
Issuer has a good faith business purpose for preserving as confidential.
Subject to the foregoing, Issuer will use its reasonable best efforts to cause
such registration statement to become effective as soon as practicable. In
connection with any such registration, Issuer and the Holder requesting such
registration shall provide each other with representations, warranties,
indemnities and other agreements customarily given in connection with such
registrations. If requested by such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement
relating to the sale of such shares, but only to the extent of obligating
Issuer in respect of representations, warranties, indemnities, contribution
and other agreements customarily made by issuers in such underwriting
agreements.

         (b) In the event that such Holder so requests, the closing of the
sale or other disposition of the Common Stock or other securities pursuant to
a registration statement filed pursuant to Section 6(a) shall occur
substantially simultaneously with the exercise of the Option.

         (c) Any registration statement prepared and filed under this Section
6 and any sale covered thereby, will be at Issuer's expense except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of the Holder's counsel related thereto. In connection with any
registration pursuant to this Section 6, Issuer and such Holder will provide
each other and any underwriter of the offering with customary representations,
warranties, covenants, indemnification, and contribution in connection with
such registration.

         7. Extension of Exercise Periods. The periods for exercise of certain
rights under Section 2 shall be extended in each such case at the request of
the Holder to the extent necessary to avoid liability by the Holder under
Section 16(b) of the Securities Exchange Act of 1934, as amended ("Section
16(b)"), by reason of such exercise.

         8. Assignment. Neither party may assign any of its rights or
obligations under this Agreement or the Option to any other person without the
express written consent of the other


<PAGE>


party. Any attempted assignment in contravention of the preceding sentence
shall be null and void.

         9. Filings; Other Actions. The parties hereto will use their
reasonable best efforts to make all filings with, and to obtain consents of,
all third parties and governmental authorities necessary for the consummation
of the transactions contemplated by this Agreement.

         10. Specific Performance. The parties acknowledge that damages would
be an inadequate remedy for a breach of this Agreement by either party and
that the obligations of the parties shall be specifically enforceable through
injunctive or other equitable relief.

         11. Severability. The provisions of this Agreement, the Combination
Agreement and any other agreement contemplated by the Combination Agreement
shall be deemed severable and the invalidity or unenforceability of any
provision of this Agreement, the Combination Agreement or any other agreement
contemplated by the Combination Agreement shall not affect the validity or
enforceability of the other provisions of this Agreement or any provisions of
such other agreement. Without limiting the generality of the foregoing, the
invalidity or unenforceability of any provision of any such other agreement
shall not affect the validity or enforceability of any provision of this
Agreement. If any provision of this Agreement or any such other agreement or
the application thereof to any Person or any circumstance, is invalid or
unenforceable, (i) a suitable and equitable provision shall be substituted
therefor in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid or unenforceable provision and (ii) the
remainder of this Agreement or any such other agreement and the application of
such provision to other Persons or circumstances shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction. If for any reason a Governmental Entity
determines that the Holder is not permitted to acquire the full number of
shares of Common Stock provided in Section 1(a) of this Agreement (as adjusted
pursuant to Sections 1(b) and 5 of this Agreement), it is the express
intention of Issuer to allow the Holder to acquire or to require Issuer to
repurchase such lesser number of shares as may be permissible, without any
amendment or modification of this Agreement or any other agreement executed or
to be executed in connection herewith.

         12. Notices. Notices, requests, instructions or other documents to be
given under this Agreement shall be in writing and shall be deemed given, (i)
when sent, if sent by facsimile, provided that a copy of the facsimile is
promptly sent by U.S. mail and confirmation of receipt has been delivered (ii)
when delivered, if delivered personally to the intended recipient, and (iii)
one business day later, if sent by overnight delivery via an international
courier service and, in each case at the respective addresses of the parties
set forth in the Combination Agreement.

         13. Expenses. Except as otherwise expressly provided in this
Agreement or in the Combination Agreement, all costs and expenses incurred in
connection with this Agreement and the transactions contemplated by this
Agreement shall be paid by the party incurring such expense, including fees
and expenses of its own financial consultants, investment bankers,
accountants, and counsel.


<PAGE>


         14. Entire Agreement. This Agreement, the Confidentiality Agreement
(as defined in the Combination Agreement) and the Combination Agreement
(including any other exhibits thereto and the ancillary agreements
contemplated thereby) constitute the entire agreement, and supersede all other
prior agreements, understandings, representations and warranties, both written
and oral, between the parties, with respect to the subject matter of this
Agreement. The terms and conditions of this Agreement shall inure to the
benefit of and be binding upon the parties and their respective successors and
permitted assigns. Nothing in this Agreement is intended to confer upon any
person or entity, other than the parties to this Agreement, and their
respective successors and permitted assigns, any rights or remedies under this
Agreement.

         15. Governing Law and Venue; Waiver of Jury Trial.

         (a) This Agreement shall be deemed to be made in and in all respects
shall be interpreted, construed and governed by and in accordance with the
laws of the State of New York without regard to the conflict of law principles
thereof. The parties hereby irrevocably and unconditionally consent to submit
to the exclusive jurisdiction of both the courts of the State of Delaware and
of the United States of America located in Wilmington, Delaware (the "Delaware
Courts") and the Quebec Superior Court located in Montreal, Quebec (the
"Quebec Court") for any litigation arising out of or relating to this
Agreement and the transactions contemplated by this Agreement, waive any
objection to the laying of venue of any such litigation in the Delaware Courts
or the Quebec Court and agree not to plead or claim in any Delaware Court or
the Quebec Court that such litigation brought therein has been brought in an
inconvenient forum; provided, however, that the parties agree that any
proceedings in the Quebec Court arising out of or relating to this Agreement
and the transactions contemplated by this Agreement shall be conducted in
English and all written documents relating to any such proceedings shall be
written in English.

         (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES
ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 15.

         16. U.S. Dollars. All amounts paid or payable hereunder, and all
prices referenced hereunder, shall be in United States Dollars.

         17. Effectiveness. This Agreement shall not be effective until, but
shall become effective automatically immediately, without any action on the
part of Issuer, Grantee or any Holder, when, the Reciprocating Event (as

The Toronto Stock Exchange of both (i) the grant of the option granted to
Issuer by Grantee under the CN Stock Option Agreement and (ii) the issuance of
the shares of Grantee's common stock issuable thereunder.

ITEM 5: PRESS RELEASE

Canadian National Logo                 Burlington Northern Santa Fe Railway Logo




FOR IMMEDIATE RELEASE

               CANADIAN NATIONAL AND BURLINGTON NORTHERN SANTA FE
                   CREATE THE LEADING NORTH AMERICAN RAILROAD

              Shippers To Benefit From Extended Single-Line Service

MONTREAL and FORT WORTH, Texas, December 20, 1999 3/4 Canadian National Railway
Company (TSE:CNR; NYSE:CNI) ("CN") and Burlington Northern Santa Fe Corporation
(NYSE:BNI) ("BNSF") today announced that their boards of directors have approved
a definitive agreement to combine their businesses. The end-to-end combination
creates North America's largest railroad and will offer shippers substantially
enhanced single-line service. Combined, the companies currently operate about
50,000 route-miles of track, employ about 67,000 people and have combined
revenues of approximately US$12.5 billion (Cdn$18.5 billion).

The combined businesses have an equity market capitalization of approximately
US$19 billion (Cdn$28 billion) based on the closing stock prices on Friday,
December 17, 1999, of US$29.75 for CN and US$28.375 for BNSF. The transaction is
expected to be accretive to earnings per share in the first year after the
combination becomes effective. The companies expect that all required regulatory
approvals can be obtained and the transaction completed by mid-2001.

Among its benefits, the combination will:

    o    Be uniquely positioned to help shippers take advantage of fast growing
         north-south trade flows within North America, while providing a fluid
         east-west transportation network serving both Canada and the United
         States. The new railroad will offer unprecedented single-line service
         with access to new markets throughout North America;

                                                                               1
                                     -more-

<PAGE>


    o    Achieve rail market share growth by generating new business
         opportunities and added efficiencies through improved asset utilization
         and service scheduling;

    o    Offer increasing employment opportunities due to the growth potential
         of the new enterprise. Because this combination is an end-to-end
         operating network, there is minimal overlap of operations and only
         minor duplication of activities, and workforce reductions are expected
         to be managed largely through normal attrition; .

    o    Maintain the culture, customer and safety focus and operational
         expertise of each railroad at the local and regional level;

    o    Combine CN's and BNSF's industry-leading service plans and CN's
         strength in forest products, automotive and chemical transportation
         with BNSF's wide geographic coverage in the western United States and
         its strong intermodal and coal businesses; and

    o    Join the two most efficient railroads in North America, each with a
         proven record of implementing previous consolidations.

CN and BNSF have principal interchanges at Chicago, Memphis, Duluth/Superior,
and Vancouver, B.C.


Terms

To implement the transaction in a tax-efficient manner, North American Railways,
Inc. will be created as the parent company for BNSF and as the companion company
for CN. The transaction will result in the shareholders of each company having
voting and ownership interests in both companies.

The shareholders of BNSF will receive for each BNSF common share a common
security consisting of one North American Railways common share and one CN
voting share that will trade together as one security.

The shareholders of CN will receive for each CN common share 1.05 CN voting
shares and, at their option, either 1.05 shares of North American Railways
common stock or 1.05 shares of CN stock exchangeable for 1.05 shares of North
American Railways common stock. The CN voting share will trade together with the
CN exchangeable share as one security and will be Canadian Property for
investment, dividend and tax purposes.

The result will be that, at all times, each company will have the same
shareholder base with each shareholder having the same economic benefits and
voting rights.

                                                                               2
                                     -more-

<PAGE>


North American Railways, by its charter, will conform to the provisions of the
CN Commercialization Act and Canadian corporate law on the composition of boards
of directors. Like CN, North American Railways shareholders will be subject to
an ownership limit whereby no single shareholder can own more than 15 percent of
North American Railways' voting shares; North American Railways will have its
head office in Montreal and will operate in both of Canada's official languages.
BNSF will continue to be headquartered in Fort Worth. Management and Board
Structure

Upon the closing of the transaction, Robert D. Krebs, Chairman and Chief
Executive Officer of BNSF, will become non-executive Chairman of North American
Railways and of CN; and Paul M. Tellier, President and Chief Executive Officer
of CN, will become President and Chief Executive Officer of North American
Railways as well as CN. E. Hunter Harrison, Executive Vice President and Chief
Operating Officer of CN, will become Chief Operating Officer of North American
Railways as well as CN; and Thomas N. Hund, Senior Vice President, Chief
Financial Officer and Treasurer of BNSF, will become Chief Financial Officer of
North American Railways and of CN. In addition, Matthew K. Rose, President and
Chief Operating Officer of BNSF, will become President and Chief Executive
Officer of BNSF.

A five-person implementation committee, consisting of Mr. Krebs, Mr. Tellier,
Mr. Harrison, Mr. Hund and Mr. Rose, will begin work immediately. The mandate of
this committee, which will operate through consensus, is to direct the
preparation of the U.S. Surface Transportation Board (STB) application and
related matters, to direct integration planning and, within regulatory limits,
to effect interim voluntary coordination agreements between CN and BNSF in such
areas as information systems, purchasing, operations and marketing.

The size and composition of the North American Railways board will be identical
to that of the CN board. The majority of directors will be Canadian residents.
The 15-member board will consist of six members drawn from each of the current
CN and BNSF boards plus three new appointees:

    o    From the current CN board: Purdy Crawford, J. V. Raymond Cyr, The
         Honorable Edward C. Lumley, David G. A. McLean, Robert Pace, and Paul
         M. Tellier;

    o    From the current BNSF board: John J. Burns, Jr., Robert D. Krebs, Roy
         S. Roberts, J. Steven Whisler, Edward E. Whitacre, Jr., and Michael B.
         Yanney;

    o    The three new appointees: Laurent Beaudoin, C.C., FCA, Chairman,
         Bombardier Inc.; Steven A. Burd, Chairman, President & Chief Executive
         Officer, Safeway Inc.; Jean C. Monty, President & Chief Executive
         Officer, BCE Inc.

Mr. Tellier and Mr. Krebs said, "This is a new railroad for a new era. We are
bringing together two highly successful railroads that share a common vision
about their role in the future - to increase revenues and earnings through
superior customer service. The benefits of a common

                                                                               3

operating plan with fully integrated single-line service; a coordinated
marketing plan; and the specific synergies available in such areas as
information technology and procurement will be fully realized.

"The combination of CN and BNSF builds the first North American railroad by
uniting the most efficient Canadian railroad with the most efficient railroad in
the United States. The new railroad, which will be the largest rail network in
North America, will have a strong balance sheet, substantial free cash flow, a
shared commitment to consistent on-time customer service, a common operating
system, and a well-balanced revenue portfolio," continued Mr. Krebs and Mr.
Tellier.

Mr. Krebs continued, "The combination uses a new model for railroad
consolidation -- one that will enable the partners to effectively integrate with
maximum efficiency and without sacrificing quality customer service. The model
carefully preserves and protects the existing identities and efficient rail
networks of each company. Revenue growth will be achieved in part through common
marketing and operating plans offering new and expanded single-line service for
shippers. Operating efficiencies will be achieved by leveraging the operating
systems of both railroads; through common purchasing to create economies of
scale; through the more productive utilization of locomotives and freight cars;
by leveraging e-commerce initiatives; and by the exchange of best practices.
Both railroads have completed successful mergers in the past four years. The
rate of growth, cash flow generation and EPS of the combined companies should be
significantly greater than what could be achieved by the companies on a
stand-alone basis."

Mr. Tellier continued, "This is good news for shareholders, employees, customers
and shippers. It gives shareholders ownership in a rail enterprise that, based
on its size and reach, is uniquely positioned to expand its market share and
improve its profitability. Employees will benefit from this end-to-end
combination, which creates a strong platform for revenue growth and the
potential for job creation in the future. It is good for customers and shippers
who, through this large single-line network, will have access to transportation
services that will provide them with the best value for their transportation
dollar. Our top priority will be to manage the process in a manner that provides
our customers with the highest quality service while continuing to ensure that
the highest standards of safety for our employees are upheld."


North American Benefits

The companies expect the combination to significantly benefit shippers across
Canada and the United States with faster and more dependable rail service and
with more routing and gateway choices.

Over 40 percent of Canada's GDP is generated by exports. Almost all of Canada's
exports now face strong competition in price and product substitution.
Increasingly, Canada's competitiveness is dependent on a transportation sector
with the efficiency required to overcome inherent disadvantages related to
distance. This combination ensures that CN is well positioned

                                                                               4
                                     -more-

to support the growth of export trade to the benefit of its customers and the
Canadian economy. It adds three more strategically located, single-line
north-south rail corridors for the movement of goods between Canada, the United
States and Mexico to the one created by CN's 1998 acquisition of Illinois
Central and marketing alliance with Kansas City Southern.

For the United States, this end-to-end combination will provide an important
rail alternative for numerous domestic markets. Moreover, the combination will
enhance U.S. efforts to be both price and product competitive in export markets
by providing an efficient rail transportation system that encourages a more even
balance of trade. America's competitiveness depends on a transportation system
that efficiently serves major markets. Customers west of Chicago will have
single-line, double-stack cleared access to the Port of Halifax, the North
American deep water port closest to Europe, trimming days of transit time to
points on BNSF. BNSF will be part of a system with single-line access to Detroit
and to key Canadian markets.


Synergies

The companies estimate that the annual impact of the revenue and cost synergies
on operating income will be between US$500 million and US$600 million (Cdn$750
million and Cdn$890 million) to be realized about evenly over the first three
years after the close of the transaction. Revenue synergies are expected to
result from the more efficient movement of goods such as automotive products
between Southern Ontario and Michigan and the southwestern and western United
States and Mexico. In addition, the network will be more competitive with trucks
and will promote growth in intermodal and merchandise traffic. Cost synergies
are expected to result primarily from asset productivity initiatives derived
from better utilization of locomotives, freight cars and facilities, purchasing
efficiencies, and economies of scale as well as combining certain administrative
activities.


Proven Track Record of Consolidations

In 1995, BNSF successfully completed the combination of Burlington Northern Inc.
and Santa Fe Pacific Corp. Since then, operating ratio has improved by more than
five percentage points and was 73 percent for the quarter ended September 30,
1999. Revenues have grown by approximately $1 billion during the past four
years, while operating expense per gross ton mile has declined by 10 percent.
BNSF also has improved on-time service dramatically to a system-wide on-time
average of 91 percent for 1999.

CN began a smooth, step-by-step integration of Illinois Central on July 1, 1999.
Today, CN spans all of Canada and mid-America, connecting the Atlantic, Pacific
and Gulf coasts. For the quarter ended September 30, 1999 the first full quarter
of combined operations following the close of the Illinois Central transaction -
CN posted an operating ratio of 71 percent, the best of any major North American
railroad for that period. Carloadings rose 10 percent over the third

                                                                               5

quarter of 1998. In the past year, CN's leading-edge service plan has generated
significantly improved on-time performance, transit times and asset utilization.

Review and Approvals

This combination is subject to, among other things, approval by the shareholders
of both companies, as well as to customary regulatory approvals. CN will proceed
with a Plan of Arrangement that will be submitted to a Canadian court to confirm
that the combination is fair to CN shareholders and complies with all relevant
Canadian statutory and0 regulatory requirements. The combination will also be
subject to approval by the STB. The combination will be accounted for as a
purchase.
