disseminated to BNSF stockholders.  The board of directors of BNSF shall
recommend approval and adoption of this Agreement and the transactions
contemplated by this Agreement by its stockholders and take all lawful action
(including the solicitation of proxies) to solicit such adoption; provided,
however, that, prior to the BNSF Stockholder Meeting, such recommendation may be
withdrawn, modified or changed to the extent that the board of directors of
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

     Stapled Unit, and the holder of each such BNSF Common Share shall cease to

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

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

                                       12
<PAGE>

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 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;

                                       13
<PAGE>

           (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.

     (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

                                       14
<PAGE>

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.

     (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

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

able to serve in that 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,

later than two business days) after the date on which the last to be fulfilled
or waived of the conditions set forth in Article VIII (other than those
conditions that by their nature are to be satisfied at the Closing, but subject
to the fulfillment or waiver of those conditions) shall be satisfied or waived
in accordance with this Agreement or such other date, time and place as the
parties may agree.  The parties shall cause the Merger Effective Time to occur
immediately prior to the Arrangement Effective Time, the Arrangement Effective
Time to occur immediately following the Merger Effective Time, and both the

                                  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 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).

                                       17
<PAGE>

     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.

     (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").

                                       18
<PAGE>

     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 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

                                       19
<PAGE>

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.

     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

                                       20
<PAGE>

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 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.

     (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.

                                       22

     (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 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

                                       23
<PAGE>

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
                    --------------------------------------

     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,

                                       24
<PAGE>

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.

     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

                                       25
<PAGE>

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.

     (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

                                       26
<PAGE>

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 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

                                       27
<PAGE>

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.

     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

                                       28
<PAGE>

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, 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.

                                       29
<PAGE>

     (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

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

or other confidentiality obligations binding upon any party or any of such
party's Subsidiaries, from the date of this Agreement until the Arrangement

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

STB, after which date access shall be granted to such information consistent

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.

     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.

in seeking any such actions, consents, approvals or waivers or making any such

meaning of Section 368(a) of the Code or to comply with the requirements of

regular and frequent basis with one or more representatives of one another to
report operational matters of significance to the transactions contemplated by
this Agreement and the general status of ongoing operations insofar as relevant

     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 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

     (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

                                       36
<PAGE>

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 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

                                       37
<PAGE>

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.

     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 exercise
all rights of ownership of the CN Common Shares purchased by BNSF upon exercise
of the option granted to BNSF under the CN Stock Option Agreement.

                                ---------------

     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

                                       38
<PAGE>

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 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

                                       39

     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;

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 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

                                       41
<PAGE>

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 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

                                       42
<PAGE>

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

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

     Customary Actions; provided, however, that any wholly owned subsidiary of

     ownership interests in any Material Subsidiary of BNSF or any securities
     convertible into or exchangeable for, or any rights, warrants or options to
     acquire, any BNSF Securities, BNSF Voting Debt or securities or ownership
     interests in any Material Subsidiary of BNSF;

     referred to in this clause (h)(ii) that is taken in the ordinary course of
     business consistent in magnitude and character with past practice (which
     shall include normal period performance reviews and related compensation
     and benefits increases and the provision of compensation and benefits

conditions:

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

           (ii) the representations and warranties of CN shall have been
     accurate both when made and at and as of the Merger 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 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 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 CN (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).

     8.3   Additional Conditions to the Obligations of CN.  The obligations of

           (ii) the representations and warranties of BNSF shall have 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

     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

                                       50
<PAGE>

     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 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,

                           -------------------------

     10.1   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
delivered by duly authorized officers of the respective parties. This Agreement
may not be assigned by any party without the consent of the other parties to
this Agreement.

     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

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

                                       52
<PAGE>

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 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

                                       53
<PAGE>

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 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

                                       54
<PAGE>

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

                                       55
<PAGE>

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

     (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

    relationships of Newco and CN and sets out the governing principles of the

                                      -2-


                                  ARTICLE 1.

                        GOVERNANCE OF THE CORPORATIONS

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"):

   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;

   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;

   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

   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.

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").

1.3.      Governance
          ----------

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

   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
<PAGE>

                                      -3-

   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.

   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:

     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;

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

     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.

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

   1.3.4. Chair. The initial Chair of the board of directors of both
   Corporations shall be [], 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.

                                      -4-

   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.

   1.3.6. Chief Executive Officer. The initial Chief Executive Officer of both
   Corporations shall be [], 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.

   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.

   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).

   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.

2.2       Record Date
          -----------

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.

          -----------------

          If dissent rights are granted to shareholders of one of the

of directors of the other Corporation shall ensure that shareholders of that
Corporation are granted equivalent dissent rights.

   effect a corresponding subdivision of the CN

   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.

   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

   Right or the Retraction Call Right, as the case may be; and

   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.

   defined in the Income Tax Act (Canada)) or does not deal at arm's length with
   such a person, Newco
<PAGE>

                                      -7-

   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

other rights, an unlimited number of CN Voting Shares to permit all future
issuances and sales of Trading Units to include a CN Voting Share.

3.5.      Notification of Certain Events

faith and in their sole discretion, economic equivalence for the purposes of

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

<PAGE>

                                      -13-

holders of the shares of the Corporation, without discrimination. Without

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).

4.10      Self-Tenders
          ------------

          Neither Corporation shall make a self-tender offer or issuer bid (a
"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.

of Newco [NAR Subco] [or to another entity controlled and wholly-owned, directly

   of its subsidiaries will, ensure that the other is in a position to comply

     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.

     Each Person who, immediately prior to the Election Deadline, is a holder of
record of CN Common Shares, will be entitled, with respect to all or 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 issued pursuant
<PAGE>

                                      -9-

     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).

 (c) Coincident with the conversion of Newco Elected Exchangeable Shares 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.

 Section 2.5  Consideration.

     For greater certainty, the consideration receivable by the former 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 the
CN Voting Shares and the CN Exchangeable Shares into which the CN Common 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, the CN
Voting Share Provisions and the CN Exchangeable Share Provisions.

 Section 2.6  Restated Articles.

     After giving effect to the Arrangement the Corporation is authorized to
file restated articles of incorporation under the CBCA.  For greater certainty
but without limiting the generality of the foregoing, the outstanding voting
shares in the capital
<PAGE>

                                      -10-

of CN shall at all times continue to be subject to the share constraints
contained in CN's articles of continuance as required pursuant to the
Commercialization Act as set forth in Exhibit "I".

                               RIGHTS OF DISSENT

 Section 3.1  Rights of Dissent.

     Holders of CN Common Shares may exercise rights of dissent ("Dissent
Rights") with respect to such shares pursuant to and in the manner set forth 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.

  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?]
<PAGE>

                                      -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 the
Depositary is required or permitted to deduct and withhold with respect to such
<PAGE>

                                      -16-

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 representing an
     accumulation of all fractional interests in Newco
<PAGE>

                                      -17-

     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 Subco's]
     intention to exercise such right at least 45 days before the Liquidation
     Date in the case of a voluntary liquidation, dissolution or
<PAGE>

                                      -18-

     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

 (a) in the case of a cash dividend declared on the Newco Common Shares, in an

<PAGE>

                                      -5-

     or the Canadian Dollar Equivalent thereof on the Newco Dividend Declaration
     Date, in each case, corresponding to the cash dividend declared on each

     CN Voting Shares; or

 (c) in the case of a dividend or other distribution of rights, options or
     warrants to subscribe for or purchase Newco Common Shares and CN Voting
     Shares represented by Newco Stapled Units (a "Newco Right"), in such number
     of rights, options or warrants to subscribe for or purchase CN Exchangeable

     Dollar Equivalent thereof) as the Newco Rights and otherwise be on the same
     terms as the Newco Rights.

 (d) in the case of a dividend or other distribution declared on the Newco
     Common Shares in property other than cash, Newco Stapled Units or Newco
     Rights, in such type and amount of property for each CN Exchangeable Share
     as is the same as or corresponds to or, in the event that it is not
     reasonably practicable in accordance with applicable legal requirements as
     determined by the Board of Directors to declare and pay the same or a
     corresponding dividend or other distribution, as is economically equivalent
     to (to be determined by the Board of Directors as contemplated by section
     3.5 hereof) the type and amount of property declared as a dividend on each

Such dividends shall be paid out of money, assets or property of the Corporation

contemplated by paragraph 3.1(b) or 3.1(c) hereof and the sending of such a
certificate to the holder of a CN Stapled Unit shall 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.

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

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.

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
<PAGE>

     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 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.

                              CERTAIN RESTRICTIONS

unless all dividends on the outstanding CN Exchangeable Shares corresponding to
dividends declared and paid to date on the Newco Common Shares shall have been

Corporation shall not at any time without, but may at any time with, the
approval of the holders of the CN Exchangeable Shares given as specified in
section 9.2 of these share provisions:

 (a) pay any dividends on the CN Limited Voting Equity Shares or any other
     shares ranking junior to the CN Exchangeable Shares, other than stock

     shares ranking junior to the CN Exchangeable Shares, as the case may be;

     dissolution, liquidation or winding-up; or

     ranking equally with, or superior to, the CN 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 being

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 Exchangeable Shares

     Exchange Rights in accordance with these share provisions, the Plan of
     Arrangement and/or the Voting and Exchange Trust Agreement, as applicable.

 (v) [NTD - other?]

Without limiting the generality of the foregoing, CN shall be entitled to treat

                          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 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
<PAGE>

                                     -11-

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 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

                                     -12-

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 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
<PAGE>

                                     -13-

     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 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
<PAGE>

                                     -14-

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 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).
<PAGE>

                                     -15-

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 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
<PAGE>

                                     -16-

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 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.

Section 8.1  Except as required by applicable law and by Article 10 hereof,

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

Section 10.1 Each holder of a CN Exchangeable Share acknowledges that the 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 Shares given in accordance with section 9.2of these share

represented by Newco Stapled Units, in lieu of such a stock dividend the
Corporation effects a corresponding and contemporaneous subdivision of the
outstanding CN Exchangeable Shares and CN Voting Shares.

Section 10.2 Each holder of a CN Exchangeable Share acknowledges that the Co-
operation Agreement further provides, in part, that Newco will not without the
prior approval of the Corporation and the prior approval of the holders of the

provision of this Exhibit "I" which may be read in a manner that is inconsistent

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 or her associates, shall hold, beneficially
own or control, directly or indirectly, voting shares to which are attached more
than fifteen (15%) of the Aggregate Votes.  Subject to Subsections 4.1 and 4.2,
the Corporation shall refuse to recognize all Ownership Rights that would

Individual Holdings by any person, together with such person's associates.

4.   Limitation on Voting Rights and dividend forfeiture
     ---------------------------------------------------

4.1  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, 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 group of
          persons of which the other is a member;

     (c)  one is a partnership  of which the other is a partner;

     (d)  one is a trust of which the other is a trustee;

     (e)  both are corporations controlled by the same person;

     (f)  both are members of a voting trust that relates to voting shares;

     (g)  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

     (h)  both are at the same time associates, within the meaning of any of
          paragraphs (a) to (g), of the same person.
<PAGE>

                                      -5-


6.2  Notwithstanding Subsection 6.1, for the purposes of this section,

     (a)  where a person who, but for this Subsection 6.2, would be an associate
          of another person submits to the Corporation a statutory declaration
          or such other declaration required by the directors stating that:

          (i)  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 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,

          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;

     (b)  two corporations are not associates pursuant to Subsection 6.1 by
          reason only that under Subsection 6.1 each is an associate of the same
          individual; and

     (c)  where it appears from the central securities register 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.

6.3  For greater certainty, no person is presumed to be an associate of any
other person for purposes of paragraph 8(4)(g) of the Act 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 an information circular
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 Exhibit "I", "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,
<PAGE>

                                      -6-

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
     ---------------

8.1  For the purposes of this Exhibit "I", 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
     ----------

9.1  Nothing in this Exhibit "I" shall be construed to apply in respect of
voting shares that:

     (a)  are held by the Minister in trust for Her Majesty in right of Canada;

     (b)  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
          share (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;
<PAGE>

                                      -7-

     (c)  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

                     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.

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>

                                      -14-

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>

                                      -15-

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>

                                      -16-

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>

                                      -17-

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.

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

             (i)  in the event of any determination by the Board of Directors of
                  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
             paragraph 5.12(a)(i) or paragraph 5.12(a)(ii) above, the Trustee
             will give notice thereof to the Beneficiaries. Such notice shall
             include a brief
<PAGE>

                                      -18-

             description of the automatic exchange of CN Exchangeable Shares for
             Newco Common Shares provided for in paragraph 5.12(c).

        (c)  In order that the Beneficiaries will be able to participate on a
             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>

                                      -19-

             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

             the provisions of this trust agreement;

        (b)  granting proxies and distributing materials to Beneficiaries as
             provided in this trust agreement;

             Exchange Rights from Newco as trustee for and on behalf of the
             Beneficiaries in accordance with the provisions of this trust
             agreement;

        (e)  exercising the Exchange Right and enforcing the benefit of the
             Automatic Exchange Rights, in each case in accordance with the

             receiving from Beneficiaries CN Exchangeable Shares and other
             requisite documents and distributing to such Beneficiaries Newco
             Stapled Units and cheques, if any, to which such Beneficiaries are

        (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 Trustee

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.

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,

Trustee hereunder.

             Voting Shares, the CN Stapled Units, the Newco Common Shares and
             the Newco Stapled Units; and

                                      -22-

        (b)  requisition, from time to time, (i) from any such registrar or
             transfer agent any information readily available from the records

             the Automatic Exchange Rights.

     Newco and CN irrevocably authorize their respective registrars and transfer

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

             on behalf of Beneficiaries in consideration of the issuance by
             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
             which, in the Trustee's opinion, materially affects the Trust
             Estate.

Section 7.5  Income Tax Returns and Reports.

     The Trustee shall, to the extent necessary, prepare and file on behalf of

institute such action, suit or proceeding and furnished the Trustee with the
security or indemnity referred to in section 7.6 and the Trustee shall have
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
competent jurisdiction such as the Trustee might have taken; it being understood
and intended that no one or more Beneficiaries shall have any right in any
manner whatsoever to affect, disturb or prejudice the rights hereby created by

to be furnished to it in the exercise of its rights, powers, duties and

the provisions of this section 7.14, it ceases to be so authorized to carry on

affected in any manner whatsoever by reason only of such event but the Trustee
shall, within 90 days after ceasing to be authorized to carry on the business of
a trust company in any Province of Canada, either become so authorized or resign

interest of any Beneficiary in any CN Stapled Units or CN Exchangeable 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 not to exercise
any Voting Rights, Exchange Rights or Automatic Exchange Rights subject to such
conflicting claims or demands and, in so doing, the Trustee shall not be or
become liable to any person on account of such election or its failure or
refusal to comply with any such conflicting claims or demands. The Trustee shall
be entitled to continue to refrain from acting and to refuse to act until:

        (a)  the rights of all adverse claimants with respect to the Voting
             Rights, Exchange Right or Automatic Exchange Rights subject to such
<PAGE>

                                      -27-

             conflicting claims or demands have been adjudicated by a final
             judgment of a court of competent jurisdiction; or

        (b)  all differences with respect to the Voting Rights, Exchange Right
             or Automatic Exchange Rights subject to such conflicting claims or
             demands have been conclusively settled by a valid written agreement
             binding on all such adverse claimants, and the Trustee shall have
             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 made
by any such adverse claimant, it may in its discretion require such 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.

negligence, recklessness or willful misconduct.

                  INDEMNIFICATION AND LIMITATION OF LIABILITY

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 Trustee's
acceptance or administration of the Trust, its compliance with its duties set
forth in this trust agreement, or any written or oral instruction delivered to
the Trustee by Newco or CN pursuant hereto.

     In no case shall Newco or CN be liable under this indemnity for any claim
against any of the Indemnified Parties unless Newco and CN shall be notified by
the Trustee of the written assertion of a claim or of any action commenced
against the Indemnified Parties, promptly after any of the Indemnified 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.

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>

                                      -30-

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

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.

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

             correcting any ambiguity or defect or inconsistent provision or
             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

             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

                               RIGHTS AGREEMENT
                               ----------------


     Rights Agreement, dated as of December 18, 1999, between BURLINGTON
NORTHERN SANTA FE CORPORATION, a Delaware corporation (the "Company"), and
_________________, a ___________ trust company (the "Rights Agent").

                              W I T N E S S E T H:
                              - - - - - - - - - -

     WHEREAS, the Board of Directors of the Company has authorized and declared
a dividend of one preferred share purchase right (a "Right") for each Common
Share (as hereinafter defined) of the Company outstanding as of the 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)
<PAGE>

of such Person, shall be the Beneficial Owner (as such term is hereinafter
defined) of 15% or 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 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

                                      -2-
<PAGE>

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

     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

     Associates until such 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

     (a) Until the earlier of (i) the close of business on the tenth day after
the Shares Acquisition Date or (ii) the close of business on the tenth Business
Day (or such later date as may be determined by action of the Board of Directors
prior to such time as any Person becomes an Acquiring Person) after the date of
the commencement by any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan of the Company or of any Subsidiary of the
Company or any entity holding Common Shares for or pursuant to the terms of any
such plan) of, or of the first public announcement of the intention of any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding Common Shares for or pursuant to the terms of any such plan) to
commence, a tender or exchange offer the consummation of which would result in
any Person becoming the Beneficial Owner of Common Shares aggregating 15% or
more of the then outstanding Common Shares (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

                                      -9-
<PAGE>

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 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

                                      -10-
<PAGE>

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 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 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

                                      -12-
<PAGE>

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:

     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

                                      -13-
<PAGE>

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 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,

                                      -14-
<PAGE>

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 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

                                      -15-
<PAGE>

to the Rights Agent for countersignature and delivery to the registered holder
in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

Certificate may exercise the Rights evidenced thereby (except as otherwise

on the reverse side thereof duly executed, to the Rights Agent at the office of

     (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

<PAGE>

     (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

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 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

                                      -17-
<PAGE>

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

                                      -18-
<PAGE>

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 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,

                                      -19-
<PAGE>

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 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

                                      -20-
<PAGE>

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.

     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

                                      -21-
<PAGE>

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 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,

                                      -22-
<PAGE>

     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 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

                                      -23-
<PAGE>

     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) 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

                                      -24-
<PAGE>

     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 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

                                      -25-
<PAGE>

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
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

                                      -26-
<PAGE>

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
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

                                      -27-
<PAGE>

     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 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

                                      -28-
<PAGE>

     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,
     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

                                      -29-
<PAGE>

     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 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.

                                      -30-
<PAGE>

     (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) 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

                                      -31-
<PAGE>

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 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

                                      -32-
<PAGE>

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.

     (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

                                      -33-
<PAGE>

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 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

                                      -34-
<PAGE>

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 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

                                      -35-
<PAGE>

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
(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 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

                                      -37-
<PAGE>

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) 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.

                                      -38-
<PAGE>

     (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 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

                                      -39-
<PAGE>

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
     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.

                                      -40-
<PAGE>

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 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

                                      -41-
<PAGE>

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.

     (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,

                                      -42-
<PAGE>

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 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 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

                                      -44-
<PAGE>

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 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

                                      -45-
<PAGE>

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
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,

                                      -46-
<PAGE>

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; 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

                                      -47-
<PAGE>

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 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

                                      -48-
<PAGE>

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.

     (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

                                      -49-
<PAGE>

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.

     (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

                                      -50-
<PAGE>

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

                                      -51-
<PAGE>

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

                                      -52-
<PAGE>

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 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

                                      -53-
<PAGE>

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 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

                                      -54-
<PAGE>

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.

                                      -55-
<PAGE>

     (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 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

                                      -56-
<PAGE>

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 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

                                      -57-
<PAGE>

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 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

                                      -58-
<PAGE>

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 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.
                  ------------------------

                                      -59-
<PAGE>

     (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 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

                                      -60-
<PAGE>

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.

     Section 26.  Notices.  Notices or demands authorized by this Agreement to
                  -------

"Series B Preferred Stock"), and the number of shares constituting such series
shall be 3,000,000.  Such number of shares may be increased or decreased by
resolution of the Board of Directors and by the filing of a certificate pursuant
to the provisions of the General Corporation Law of the State of Delaware
stating that such increase or reduction has been so authorized; provided,
                                                                --------
however, that no decrease shall reduce the number of shares of Series B
- -------
Preferred Stock to a number less than that of the shares then outstanding plus
the number of shares of Series B Preferred Stock issuable upon exercise of

outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Corporation.

     Section 2.  Dividends and Distributions.
                 ---------------------------

     (A) Subject to the prior and superior rights of the holders of any shares
of any series of Preferred Stock ranking prior and superior to the shares of
Series B Preferred Stock with respect to dividends, the holders of shares of
Series B Preferred Stock shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash to holders of record on the last business
day of March, June, September and December in each year (each such date being
referred to herein as a "Quarterly Dividend Record Date"), commencing on the
first Quarterly Dividend Record Date after the first issuance of a share or
fraction of a share of Series B Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to, subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions other than a dividend payable in
shares of Common Stock (hereinafter defined) or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock, par value $0.01 per share, of the Corporation (the "Common Stock")
since the immediately preceding Quarterly Dividend Record Date, or, with respect
to the first Quarterly Dividend Record Date, since the first issuance of any
share or fraction of a share of Series B Preferred Stock.  In the event the
Corporation shall at any time following December 31, 1999 (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Series B Preferred Stock were entitled immediately prior to such event
under the preceding sentence shall be adjusted by multiplying each such amount
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     (B) The Corporation shall declare a dividend or distribution on the Series
B Preferred Stock as provided in paragraph (A) above at the time it declares a
dividend or distribution on the Common Stock (other than a dividend payable in
shares of Common Stock).

     (C) No dividend or distribution (other than a dividend payable in shares of
Common Stock) shall be paid or payable to the holders of shares of Common Stock
unless, prior thereto, all accrued but unpaid dividends to the date of such
dividend or distribution shall have been paid to the holders of shares of Series
B Preferred Stock.

                                       2
<PAGE>

     (D) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series B Preferred Stock from the Quarterly Dividend Record Date next
preceding the date of issue of such shares of Series B Preferred Stock, unless
the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Record Date, in which case dividends on such shares shall
begin to accrue from the date of issue of such shares, or unless the date of
issue is a Quarterly Dividend Record Date or is a date after the record date for
the determination of holders of shares of Series B Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Record Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Record Date. Accrued but unpaid dividends shall not
bear interest.  Dividends paid on the shares of Series B Preferred Stock in an
amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding.  The Board of Directors may fix a
record date for the determination of holders of shares of Series B Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date fixed
for the payment thereof.

     Section 3.  Voting Rights.  The holders of shares of Series B Preferred
                 -------------
Stock shall have the following voting rights:

     (A) Subject to the provision for adjustment hereinafter set forth, each one
one-hundredth of a share of Series B Preferred Stock shall entitle the holder
thereof to one vote on all matters submitted to a vote of the stockholders of
the Corporation.  In the event the Corporation shall at any time following
December 31, 1999 (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding shares of Common Stock or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the number of votes per share to which holders of shares of
Series B Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) Except as otherwise provided herein or by law, the holders of shares of
Series B Preferred Stock and the holders of shares of Common Stock and any other
capital stock of the Corporation having general voting rights shall vote
together as one class on all matters submitted to a vote of stockholders of the
Corporation.

     (C)  (i)  Whenever, at any time or times, dividends payable on any share or
     shares of Series B Preferred Stock shall be in arrears in an amount equal
     to at least six full quarterly dividends (whether or not declared and
     whether or not consecutive), the holders of record of the outstanding
     Series B Preferred Stock shall have the exclusive right, voting separately
     as a single class, to elect two directors of the Corporation at a special



                                       3
<PAGE>

     meeting of stockholders of the Corporation or at the Corporation's next
     annual meeting of stockholders, and at each subsequent annual meeting of
     stockholders, as provided below.  At elections for such directors, the
     holders of shares of Series B Preferred Stock shall be entitled to cast one
     vote for each one one-hundredth of a share of Series B Preferred Stock
     held.

          (ii) Upon the vesting of such right of the holders of the Series B
     Preferred Stock, the maximum authorized number of members of the Board of
     Directors shall automatically be increased by two and the two vacancies so
     created shall be filled by vote of the holders of the outstanding Series B
     Preferred Stock as hereinafter set forth. A special meeting of the
     stockholders of the Corporation then entitled to vote shall be called by
     the Chairman or the President or the Secretary of the Corporation, if
     requested in writing by the holders of record of not less than 10% of the
     Series B Preferred Stock then outstanding.  At such special meeting, or, if
     no such special meeting shall have been called, then at the next annual
     meeting of stockholders of the Corporation, the holders of the shares of
     the Series B Preferred Stock shall elect, voting as above provided, two
     directors of the Corporation to fill the aforesaid vacancies created by the
     automatic increase in the number of members of the Board of Directors.  At
     any and all such meetings for such election, the holders of a majority of
     the outstanding shares of the Series B Preferred Stock shall be necessary
     to constitute a quorum for such election, whether present in person or by
     proxy, and such two directors shall be elected by the vote of at least a
     plurality of shares held by such stockholders present or represented at the
     meeting.  Any director elected by holders of shares of the Series B
     Preferred Stock pursuant to this Section may be removed at any annual or
     special meeting, by vote of the holders of a majority of the outstanding
     shares of the Series B Preferred Stock voting as a class, with or without
     cause.  In case any vacancy shall occur among the directors elected by the
     holders of the Series B Preferred Stock pursuant to this Section, such
     vacancy may be filled by the remaining director so elected, or his or her
     successor then in office, and the director so elected to fill such vacancy
     shall serve until the next meeting of stockholders for the election of
     directors.  After the holders of the Series B Preferred Stock shall have
     exercised their right to elect Directors in any default period and during
     the continuance of such period, the number of Directors shall not be
     further increased or decreased except by vote of the holders of Series B
     Preferred Stock as herein provided or pursuant to the rights of any equity
     securities ranking senior to or pari passu with the Series B Preferred
                                     ---- -----
     Stock.


                                       4
<PAGE>

          (iii) The right of the holders of the Series B Preferred Stock, voting
     separately as a class, to elect two members of the Board of Directors of
     the Corporation as aforesaid shall continue until, and only until, such
     time as all arrears in dividends (whether or not declared) on the Series B
     Preferred Stock shall have been paid or declared and set apart for payment,
     at which time such right shall terminate, except as herein or by law
     expressly provided, subject to revesting in the event of each and every
     subsequent default of the character above-mentioned.  Upon any termination
     of the right of the holders of the shares of the Series B Preferred Stock
     as a class to vote for directors as herein provided, the term of office of
     all directors then in office elected by the holders of Series B Preferred
     Stock pursuant to this Section shall terminate immediately.  Whenever the
     term of office of the directors elected by the holders of the Series B
     Preferred Stock pursuant to this Section shall terminate and the special
     voting powers vested in the holders of the Series B Preferred Stock
     pursuant to this Section shall have expired, the maximum number of members
     of the Board of Directors of the Corporation shall be such number as may be
     provided for in the By-laws of the Corporation irrespective of any increase
     made pursuant to the provisions of this Section.

     (D) Except as set forth herein, holders of Series B Preferred Stock shall
have no special voting rights and their consent shall not be required (except to
the extent they are entitled to vote with holders of Common Stock as set forth
herein) for taking any corporate action.

     Section 4.  Certain Restrictions.
                 --------------------

     (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series B Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series B Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

          (i)   declare or pay dividends on, make any other distributions on, or
     redeem or purchase or otherwise acquire for consideration any shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series B Preferred Stock;

          (ii)  declare or pay dividends on or make any other distributions on
     any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series B Preferred Stock,
     except dividends paid ratably on the Series B Preferred Stock and all such
     parity stock on which dividends are payable or in arrears in proportion to
     the total amounts to which the holders of all such shares are then
     entitled;

          (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or



                                       5
<PAGE>

     winding up) with the Series B Preferred Stock, provided that the
     Corporation may at any time redeem, purchase or otherwise acquire shares of
     any such parity stock in exchange for shares of any stock of the
     Corporation ranking junior (either as to dividends or upon dissolution,
     liquidation or winding up) to the Series B Preferred Stock; or

          (iv)  purchase or otherwise acquire for consideration any shares of
     Series B Preferred Stock, except in accordance with a purchase offer made
     in writing or by publication (as determined by the Board of Directors) to
     all holders of such shares upon such terms as the Board of Directors, after
     consideration of the respective annual dividend rates and other relative
     rights and preferences of the respective series and classes, shall
     determine in good faith will result in fair and equitable treatment among
     the respective series or classes.

     (B) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.  Reacquired Shares.  Any shares of Series B Preferred Stock
                 -----------------
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof.  All such
shares shall upon their cancellation become authorized but unissued shares of
Series B Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

     Section 6.  Liquidation, Dissolution or Winding Up.  (A)  Upon any
                 --------------------------------------
voluntary liquidation, dissolution or winding up of the Corporation, no
distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series B Preferred Stock unless, prior thereto, the holders of shares of Series
B Preferred Stock shall have received $0.01 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment (the "Series B Liquidation Preference").  Following
the payment of the full amount of the Series B Liquidation Preference, no
additional distributions shall be made to the holders of shares of Series B
Preferred Stock unless, prior thereto, the holders of shares of Common Stock
shall have received an amount per share (the "Common Adjustment") equal to the
quotient obtained by dividing (i) the Series B Liquidation Preference by (ii)
100 (as appropriately adjusted as set forth in subparagraph C below to reflect
such events as stock splits, stock dividends and recapitalizations with respect
to the Common Stock) (such number in clause (ii), the "Adjustment Number").
Following the payment of the full amount of the Series B Liquidation Preference
and the Common Adjustment in respect of all outstanding shares of Series B
Preferred Stock and Common Stock, respectively, holders of Series B Preferred
Stock and holders of shares of Common Stock shall receive their ratable and
proportionate share of the


                                       6
<PAGE>

remaining assets to be distributed in the ratio, on a per share basis, of the
Adjustment Number to 1 with respect to such Preferred Stock and Common Stock, on
a per share basis, respectively.

     (B) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series B Liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, which
rank on a parity with the Series B Preferred Stock, then such remaining assets
shall be distributed ratably to the holders of such parity shares in proportion
to their respective liquidation preferences.

     (C) In the event the Corporation shall at any time following December 31,
1999, (i) declare any dividend on Common Stock payable in shares of Common
Stock, (ii) subdivide the outstanding shares of Common Stock or (iii) combine
the outstanding Common Stock into a smaller number of shares, then in each such
case the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

     Section 7.  Consolidation, Merger, etc.  In case the Corporation shall
                 ---------------------------
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series B Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock or (iii) combine the outstanding Common Stock into a smaller number
of shares, then in each such case the amount set forth in the preceding sentence
with respect to the exchange or change of shares of Series B Preferred Stock
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

     Section 8.  Redemption.  The shares of a Series B Preferred Stock shall
                 ----------
not be redeemable by the Corporation.  The preceding sentence shall not limit
the ability of the Corporation to purchase or otherwise deal in such shares of
stock to the extent permitted by law.

     Section 9.  Ranking.  The Series B Preferred Stock shall rank junior to
                 -------
all other series of the Corporation's preferred stock (whether with or without
par value) as to the payment of dividends and the distribution of assets, unless
the terms of any such series shall provide otherwise.

<PAGE>

     Section 10.  Amendment.  The Certificate of Incorporation of the
                  ---------
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series B Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of a
majority of the outstanding shares of Series B Preferred Stock, voting
separately as a class.

     Section 11.  Fractional Shares.  Series B Preferred Stock may be issued in
                  -----------------
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series B Preferred Stock.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate to be
signed by [Name], its [Title], and the same to be attested by [Name], its
[Title], this 18th day of December, 1999.

with the appropriate Form of Election to Purchase and related Certificate duly
executed. The number of Rights evidenced by this Right Certificate (and the

Affiliate or Associate of any such Acquiring Person (as such terms are defined
in the Rights Agreement), (ii) under certain circumstances specified in the
Rights Agreement, a transferee of any such Acquiring Person, Associate or

Acquiring Person, or an Affiliate or Associate of an Acquiring Person, such
Rights shall become null and void and no holder hereof shall have any right with
respect to such Rights from and after the occurrence of any such Triggering
Event.

     As provided in the Rights Agreement, the Purchase Price and the number and
kind of Preferred Shares or other securities, which may be purchased upon the

                            SUMMARY OF RIGHTS PLAN
                            ----------------------


     On December 18, 1999, the Board of Directors of BURLINGTON NORTHERN SANTA
FE CORPORATION (the "Company") declared a dividend distribution of one Right for
each outstanding share of common stock, par value $0.01 per share (the "Common
Stock"), of the Company to stockholders of record at the close of business on
December 31, 1999 (the "Record Date").  Except as described below, each Right,
when exercisable, entitles the registered holder to purchase from the Company
one one-hundredth of a share of Junior Participating Preferred Stock, Series B,
par value $0.01 per share (the "Preferred Stock"), at a price of $100.00 per one
one-hundredth share (the "Purchase Price"), subject to adjustment.  The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and _________________________, as Rights
Agent.

     Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Right certificates will be
distributed.  Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of the outstanding shares of Common Stock (the "Shares
Acquisition Date") or (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors of the Company (the "Board of
Directors") prior to the time that any person becomes an Acquiring Person)
following the commencement of (or a public announcement of an intention to make)
a tender or exchange offer if, upon consummation thereof, such person or group
would be the  beneficial owner of 15% or more of such outstanding shares of
Common Stock (the earlier of such dates being called the "Distribution Date"),
the Rights will be evidenced by the Common Stock certificates together with a
copy of the Summary of Rights Plan and not by separate certificates.

     The Rights Agreement also provides that, until the Distribution Date, the
Rights will be transferred with and only with the Common Stock.  Until the
Distribution Date (or earlier redemption, expiration or termination of the
Rights), the transfer of any certificates for Common Stock, with or without a
copy of this Summary of Rights Plan, will also constitute the


<PAGE>

transfer of the Rights associated with the Common Stock represented by such
certificates. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date and, thereafter, such separate Right Certificates alone will
evidence the Rights.

     The Rights are not exercisable until the Distribution Date and will expire
at the earliest of (i) December 18, 2009 (the "Final Expiration Date"), (ii) the
redemption of the Rights by the Company as described below, (iii) the time
immediately prior to the effectiveness of the merger of Western Merger Sub,
Inc., a Delaware corporation with and into the Company pursuant to a Combination
Agreement dated as of December 18, 1999, as such Combination Agreement may be
amended from time to time (the "Combination Agreement"), and (iv) the exchange
of all Rights for Common Stock as described below.

     In the event that any person (other than the Company, its affiliates or any
person receiving newly-issued shares of Common Stock directly from the Company)
becomes the beneficial owner of 15% or more of the then outstanding shares of
Common Stock, each holder of a Right will thereafter have the right to receive,
upon exercise at the then current exercise price of the Right, Common Stock (or,
in certain circumstances, cash, property or other securities of the Company)
having a value equal to two times the exercise price of the Right.  The Rights
Agreement contains an exemption for any issuance of Common Stock by the Company
directly to any person (for example, in a private placement or an acquisition by
the Company in which Common Stock is used as consideration), even if that person
would become the beneficial owner of 15% or more of the Common Stock, provided
that such person does not acquire any additional shares of Common Stock.

     In the event that, at any time following the Shares Acquisition Date, the
Company is acquired in a merger or other business combination transaction or 50%
or more of the Company's assets or earning power are sold, proper provision will
be made so that each holder of a Right will thereafter have the right to
receive, upon exercise at the then current exercise price of the Right, common
stock of the acquiring or surviving company having a value equal to two times
the exercise price of the Right.

     Notwithstanding the foregoing, following the occurrence of any of the
events set forth in the preceding two paragraphs (the "Triggering Events"), any
Rights that are, or (under certain circumstances specified in the Rights
Agreement) were, beneficially owned by any Acquiring Person will immediately
become null and void.

     The Purchase Price payable, and the number of shares of Preferred Stock or
other securities or property issuable, upon exercise of the Rights, are subject
to adjustment from time to time to prevent dilution, among other circumstances,
in the event of a stock dividend on, or a



                                      2
<PAGE>

subdivision, split, combination, consolidation or reclassification of, the
Preferred Stock or the Common Stock, or a reverse split of the outstanding
shares of Preferred Stock or the Common Stock.

     At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 15% or more of the outstanding
Common Stock and prior to the acquisition by such person or group of 50% or more
of the outstanding Common Stock, the Board of Directors may exchange the Rights
(other than Rights owned by such person or group, which have become void), in
whole or in part, at an exchange ratio of one share of Common Stock per Right
(subject to adjustment).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
the Purchase Price.  The Company will not be required to issue fractional shares
of Preferred Stock or Common Stock (other than fractions in multiples of one
one-hundredths of a share of Preferred Stock) and, in lieu thereof, an
adjustment in cash may be made based on the market price of the Preferred Stock
or Common Stock on the last trading date prior to the date of exercise.

     At any time after the date of the Rights Agreement until the time that a
person becomes an Acquiring Person, the Board of Directors may redeem the Rights
in whole, but not in part, at a price of $0.01 per Right (the "Redemption
Price"), which may (at the option of the Company) be paid in cash, shares of
Common Stock or other consideration deemed appropriate by the Board of
Directors.  Upon the effectiveness of any action of the Board of Directors
ordering redemption of the Rights, the Rights will terminate and the only right
of the holders of Rights will be to receive the Redemption Price.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     The provisions of the Rights Agreement may be amended by the Company,
except that any amendment adopted after the time that a person becomes an
Acquiring Person may not adversely affect the interests of holders of Rights.

     As of December 15, 1999, there were 454,945,828 shares of Common Stock
outstanding and 30,048,057 shares of Common Stock reserved for issuance under
employee benefit plans. Each outstanding share of Common Stock on December 31,
1999 will receive one Right. Three million  (3,000,000) shares of Preferred
Stock will be reserved for issuance in the event of exercise of the Rights.

     The Rights have certain anti-takeover effects.  The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
without conditioning the offer on the



                                      3
<PAGE>

Rights being redeemed or a substantial number of Rights being acquired, and
under certain circumstances the Rights beneficially owned by such a person or
group may become void. The Rights should not interfere with the transaction
contemplated by the Combination Agreement or any other merger or other business
combination approved by the Board of Directors because, if the Rights would
become exercisable as a result of such merger or business combination, the Board
of Directors may, at its option, at any time prior to the time that any Person
becomes an Acquiring Person, redeem all (but not less than all) of the then
outstanding Rights at the Redemption Price.

     A copy of the Rights Agreement is being filed with the Securities and
Exchange Commission as an exhibit to a Registration Statement on Form 8-A.  This
summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement.

$0.01 per share ("Special Voting Stock"), and (c) [               ] shares shall

SECTION I:  PROVISIONS RELATING TO COMMON STOCK

     1.   Voting Rights.  At all times, each holder of Common Stock of the
Corporation shall be entitled to one vote for each share of Common Stock
standing in the name of such holder on the books of the Corporation.  In respect
of all matters concerning the voting of shares of the Corporation, except as
required by law or 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.   Common Stock to be Reserved.  The Corporation shall at all times
reserve and keep available out of its authorized Common Stock, solely for
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 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.

                                       2
<PAGE>

     (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:

               (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

                                       3
<PAGE>

               (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.

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.

                                       4
<PAGE>

     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 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.

currently exercisable options and rights to acquire such a share or such a

     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

                                       6
<PAGE>

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 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

                                       7
<PAGE>

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;

          (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.

                                       8
<PAGE>

     (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

          (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

                                       9

<PAGE>

          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;

          (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

                                      10

<PAGE>

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

or its name or to issue a voting share to him, her or it until that person has
furnished the declaration.

     11.  Powers of Directors.  (a)  Subject to applicable law, in the

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

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.

     (c) In administering the provisions of this Article SIXTH, the directors of
the Corporation may rely upon:

     (d) Wherever in this Article SIXTH it is necessary to determine the opinion
of the board of directors of the Corporation, such opinion shall be expressed

     13.  Amendments to this Section.  No amendment to this Restated Certificate
of Incorporation shall amend, alter, change or repeal any of the provisions of
this Article SIXTH 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

                                  STOCKHOLDERS

     Section 1.  Time and Place of Meetings.  All meetings of the stockholders
for the election of directors or for any other purpose shall be held at such
time and place, within or without the State of Delaware, as shall be designated

principal office of the Corporation.

     Section 2.  Annual Meetings.  An annual meeting of stockholders shall be
held for the purpose of electing directors and transacting such other business
as may properly be brought before the meeting.  The date of the annual meeting
shall be determined by the Board of Directors.

any purpose or purposes, unless otherwise prescribed by the Certificate of

Executive Officer, the President or the Secretary of the Corporation of
stockholders owning a majority in amount of the entire capital stock of the
Corporation issued and outstanding and entitled to vote.

     Section 4.  Notice of Meetings.  Written notice of each meeting of the
stockholders stating the place, date and time of the meeting shall be given not
less than ten nor more than sixty days before the date of the meeting, to each

<PAGE>

any special meeting of stockholders shall state the purpose or purposes for
which the meeting is called. Business transacted at any special meeting of
stockholders shall be limited to the purposes stated in the notice. Neither the
business to be transacted at, nor the purpose of, an annual or special meeting
of stockholders need be specified in any written waiver of notice.

     Section 5.  Quorum; Adjournments.  The holders of a majority of the stock
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the

of the holders of a majority of such stock, to adjourn the meeting to another
time and/or place, without notice other than announcement at the meeting, except
as hereinafter provided, until a quorum shall be present or represented.  At
such adjourned meeting, at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at the original
meeting.  If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.  Withdrawal of stockholders from any meeting shall not
cause the failure of a duly constituted quorum at such meeting.

stockholder of the Common Stock shall be entitled to vote, in person, or by
proxy appointed in an instrument in writing subscribed by the stockholder or

the meeting.  Each stockholder of the Common Stock shall be entitled to one vote
for each share of voting stock held by such stockholder, unless otherwise
provided in the Delaware Law or the Certificate of Incorporation.

     (b) When a quorum is present at any meeting, the affirmative vote of the
holders of a majority of the Common Stock having voting 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 express provision of law or
of the Certificate of Incorporation, a different vote is required, in which case
such express provision shall govern and control the decision of such question.
Any stockholder who is in attendance at a meeting of stockholders either in
person or by proxy, but who abstains from the vote on any matter, shall not be
deemed present or represented at such meeting for purposes of the preceding
sentence with respect to such vote, but shall be deemed present or represented

taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.  Prompt notice of the taking of the



<PAGE>

corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.


                                  ARTICLE III
                                   DIRECTORS

     Section 1.  General Powers.  The business and affairs of the Corporation
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 may be done by, the Corporation and do all such lawful 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.

     Section 2.  Number, Qualification and Tenure.  The Board of Directors of
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.
The directors shall be elected at the annual meeting of the stockholders, except
as provided in the Certificate of Incorporation or Section 3 of this Article,
and each director elected shall hold office until his or her successor is
elected and qualified or until his or her earlier death, termination,
resignation or removal from office.  Directors need not be stockholders.

     Section 3.  Vacancies and Newly-Created Directorships. Vacancies and newly
created directorships resulting from any increase in the number of directors may
be filled by a majority of the directors then in office, although less than a
quorum, or by a sole remaining director, and each director so chosen shall hold
office until his or her successor is elected and qualified or until his or her
earlier death, termination, resignation, retirement, disqualification or removal
from office.  If there are no directors in office, then an election of directors
may be held in the manner provided by law.

     Section 4.  Place of Meetings.  The Board of Directors may hold meetings,
both regular and special, either within or without the State of Delaware.

to be known as the annual meeting, immediately following each annual meeting of
the stockholders.  Other regular meetings of the Board of Directors shall be
held at such time and place as shall from time to time be determined by the
Board.  No notice of regular meetings need be given, other than by 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


<PAGE>

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 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



<PAGE>

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 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 specifically
prohibited by the Certificate of Incorporation or these By-laws, 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.

                    CERTIFICATES OF STOCK AND THEIR TRANSFER

     Section 1.  Form.  The shares of the Corporation shall be represented by

resolution or resolutions that some or all of any or all

<PAGE>

classes or series of the Corporation's stock shall be uncertificated shares.
Each certificate for shares shall be consecutively numbered or otherwise
identified. Certificates of 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 Assistant Secretary of the Corporation. Where a certificate
is countersigned by a transfer agent, other than the Corporation or an employee
of the Corporation, or by a registrar, the signatures of one or more officers of
the Corporation may be facsimiles. In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent or registrar
before such certificate is issued, the certificate may be issued by the
Corporation with the same effect as if such officer, transfer agent or registrar
were such officer, transfer agent or registrar at the date of its issue.

     Section 2.  Transfer.  Upon surrender to the Corporation or the transfer
agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, the Corporation shall issue a new certificate of stock or
uncertificated shares in place of any certificate theretofore issued by the
Corporation to the person entitled thereto, cancel the old certificate and

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 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), 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 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.

<PAGE>

     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 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,

<PAGE>

would have had the power and authority to indemnify any or all of its directors,
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.

     These By-laws may be altered, amended or repealed or new By-laws may be

                                                                  EXECUTION COPY

                           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.

                                       2
<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

                                       3
<PAGE>

applicable Canadian securities laws. 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 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

                                       4
<PAGE>

          (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).

     (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.

                                       5
<PAGE>

     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.

     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

                                       6
<PAGE>

     (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 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.

                                       7
<PAGE>

     (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 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

                                       8

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.

     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

                                                                  EXECUTION COPY

                          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.

                                       2
<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.

                                       3
<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.

                                       4
<PAGE>

     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 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

                                       5
<PAGE>

     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 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

                                       6
<PAGE>

     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.

     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

                                       7
<PAGE>

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

    Canadian National and Burlington Northern Santa Fe Create the
    Leading North American Railroad

    12/20/99

           Shippers To Benefit From Extended Single-Line Service

   MONTREAL and FORT WORTH, Texas, December 20, 1999 - 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:

        .  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;
        .  Achieve rail market share growth by generating new business
           opportunities and added efficiencies through improved asset
           utilization and service scheduling;
        .  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;
        .  Maintain the culture, customer and safety focus and operational
           expertise of each railroad at the local and regional level;
        .  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
        .  Join the two most efficient railroads in North America, each with a
           proven record of implementing previous consolidations.
<PAGE>

     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.

     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.
<PAGE>

     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:

        .  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;
        .  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;
        .  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 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
<PAGE>

     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 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
<PAGE>

     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 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 and
     regulatory requirements. The combination will also be subject to approval
     by the STB. The combination will be accounted for as a purchase.
