For the purposes of this Agreement the date of this Agreement shall be deemed

and subject to the provisions hereinafter set forth, approved this Agreement
and the transactions contemplated hereby and resolved to recommend the adoption
of this Agreement by the stockholders of the Company; and

    WHEREAS, the Company, Parent and Acquisition desire to amend and restate

    NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, the

subject to and upon the terms and conditions of this Agreement and the Delaware
General Corporation Law (the "Delaware Law"), Acquisition shall be merged with

Article VI, the consummation of the Merger will take place as promptly as
practicable (and in any event within one business day) after satisfaction or
waiver of the conditions set forth in Article VI, at the offices of Jones, Day,
Reavis & Pogue, Dallas, Texas, unless another date, time or place is agreed to

prior to the Effective Time, at the Effective Time the Certificate of
Incorporation of the Surviving Corporation shall be amended to become identical

Certificate of Incorporation of the Surviving Corporation shall not amend (i)
the name of the Surviving Corporation (ii) the terms of the Company Preferred
Shares (as defined in Section 1.6(a)(ii)) provided in the Certificate of
Designations with respect to the Company Preferred Shares, (iii) the voting
rights as specified in Article Fourth of the Certificate of Incorporation of

provisions regarding indemnification and insurance as described in Section

    SECTION 1.5  Directors and Officers.  The directors of Acquisition
immediately prior to the Effective Time shall be the initial directors of the

the Merger and without any action on the part of Parent, Acquisition, the
Company or the holders of any of the following securities:

         (i) Each share of common stock, par value $.01 per share of the
    Company (each a "Company Common Share" and collectively, the "Company
    Common Shares") issued and outstanding immediately prior to the Effective
    Time (excluding any Company Common Shares to be canceled pursuant to
    Section 1.6(c)) shall be converted into the right to receive $6.50 in value
    (the "Merger Consideration").  The Merger Consideration shall be payable in
    cash, subject to Parent's option in Section 1.6(b) below.

         (ii)    Each share of 8 1/2% Convertible Exchangeable Preferred Stock,

    immediately prior to the Effective Time shall remain issued and outstanding
    and have, as to the Surviving Corporation, the identical powers,
    preferences, rights, qualifications, limitations and restrictions as such
    Company Preferred Shares presently have.

    (b)  Option to Substitute Parent Common Shares.  Parent, in its sole
discretion, may elect to satisfy up to $4.00 of the Merger Consideration with
shares of common stock, no par value, of Parent ("Parent Common Shares"),
having a value determined by reference to the Parent Share Price (as defined
below) equal to the portion of the Merger Consideration to be satisfied with
such shares (the "Stock Election Value").  Parent must make such election prior
to the opening for trading on the fifth trading day prior to the date of the
Special Meeting (as defined in Section 1.12) by issuing a press release to the
Dow Jones News Service indicating such election.  Parent will substantially
simultaneously notify the Company of such election.  "Parent Share Price" shall
mean the weighted average price (rounded to the nearest one hundred thousandth)
of Parent Common Shares on the Toronto Stock Exchange (the "TSE") and the New
York Stock Exchange (the "NYSE") for the five trading days immediately
preceding the fifth trading day prior to the date of the Special Meeting.  For
purposes of determining the Parent Share Price, transactions occurring on the
TSE shall be translated into U.S. dollars based on the noon





                                       3
<PAGE>   9
buying rate in New York City for cable transfers payable in foreign currencies
as certified for customs purposes by the Federal Reserve Bank of New York on
the date of such transaction.  The number of Parent Common Shares (rounded to
the nearest one hundred thousandth) having a value equal to the Stock Election
Value is referred to as the "Stock Merger Consideration," and the amount of
cash equal to $6.50 less the Stock Election Value is referred to as the "Cash
Merger Consideration."

    (c)  Cancellation.  Each Company Common Share held in the treasury of the
Company and each Company Common Share owned by Parent, Acquisition or any
direct or indirect wholly owned subsidiary of the Company or Parent immediately
prior to the Effective Time shall, by virtue of the Merger and without any
action on the part of the holder thereof, cease to be outstanding, be canceled
and retired without payment of any consideration therefor and cease to exist.

    (d)  Capital Stock of Acquisition.  Each share of common stock, $.01 par
value, of Acquisition issued and outstanding immediately prior to the Effective
Time shall be converted into and exchanged for one validly issued, fully paid
and nonassessable share of common stock, $.01 par value, of the Surviving
Corporation.

    SECTION 1.7  Exchange of Certificates.

    (a)  Paying Agent and Procedures.  Prior to the Effective Time, a bank or
trust company shall be designated by Parent (the "Paying Agent") to act as
agent in connection with the Merger to receive the Merger Consideration to
which holders of Company Common Shares shall become entitled pursuant to
Section 1.6.  Promptly after the Effective Time, the Surviving Corporation
shall cause to be mailed to each record holder, as of the Effective Time, of a
certificate or certificates (the "Certificates") that, prior to the Effective
Time, represented Company Common Shares, a customary form of letter of
transmittal and instructions for use in effecting the surrender of the
Certificates for payment of the Merger Consideration in exchange therefor.
Upon the surrender of each such Certificate which represented Company Common
Shares, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the Paying Agent shall
deliver to the holder of such Certificate in exchange therefor (i) the Cash
Merger Consideration multiplied by the number of Company Common Shares formerly
represented by such Certificate and (ii)  if applicable, and subject to Section
1.7(f), the Stock Merger Consideration multiplied by the number of Company
Common Shares formerly represented by such Certificate, and such Certificate
shall forthwith be canceled.  Until so surrendered and exchanged, each such
Certificate (other than Certificates representing Company Common Shares
canceled pursuant to Section 1.6(c)) shall represent solely the right to
receive the Merger Consideration.  No interest shall be paid or accrue on the
Merger Consideration.  If the Merger Consideration (or any portion thereof) is
to be delivered to any person other than the person in whose name the
Certificate surrendered in exchange therefor is registered, it shall be a
condition





                                       4
<PAGE>   10
to such exchange that the Certificate so surrendered shall be properly endorsed
or otherwise be in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other taxes required by
reason of the payment of the Merger Consideration to a person other than the
registered holder of the Certificate surrendered, or shall establish to the
satisfaction of the Paying Agent that such tax has been paid or is not
applicable.

    (b)  Consideration.  At the Effective Time, Parent or Acquisition shall
deposit, or cause to be deposited, in trust with the Paying Agent for the
benefit of the holders of Company Common Shares the Merger Consideration to
which holders of Company Common Shares shall be entitled at the Effective Time
pursuant to Section 1.6 hereof.

    (c)  Investment of Merger Consideration.  The Cash Merger Consideration
shall be invested by the Paying Agent, as directed by Parent, provided such
investments shall be limited to direct obligations of the United States of
America, obligations for which the full faith and credit of the United States
of America is pledged to provide for the payment of principal and interest,
commercial paper rated of the highest quality by Moody's Investors Service,
Inc. or Standard & Poor's Corporation, or certificates of deposit issued by a
commercial bank having at least $25,000,000,000 in assets.

    (d)  Termination of Duties.  Promptly following the date which is six
months after the Effective Time, Parent will cause the Paying Agent to deliver
to the Surviving Corporation all cash and documents in its possession relating
to the transactions described in this Agreement, and the Paying Agent's duties
shall terminate.  Thereafter, each holder of a Certificate may surrender such
Certificate to Parent and (subject to applicable abandoned property, escheat
and similar laws) receive in exchange therefor the Merger Consideration,
without any interest thereon.

    (e)  No Liability.  Neither Parent, Acquisition nor the Company shall be
liable to any holder of Company Common Shares for any Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

    (f)  No Certificates For Small Lots or Fractional Shares.

         (i) No certificates or scrip representing (A) less than 100 Parent
    Common Shares or (B) fractional Parent Common Shares shall be issued upon
    the surrender for exchange of Certificates that immediately prior to the
    Effective Time represented Company Common Shares which have been converted
    pursuant to Section 1.6, and such interests will not entitle the
    surrendering Certificate holder to vote or to any rights of a shareholder
    of Parent.

         (ii)    As promptly as practicable following the Effective Time, the
    Paying Agent shall determine the aggregate number of Parent Common Shares
    with





                                       5
<PAGE>   11
    respect to which certificates or scrip will not be issued pursuant to
    Section 1.7(f)(i)(A) or (B) (after taking into account all Company Common
    Shares held at the Effective Time by such holder) (collectively, the
    "Excess Shares") and, on behalf of former holders of Certificates
    representing Company Common Shares shall sell the Excess Shares at then-
    prevailing prices on the NYSE, all in the manner provided in Section
    1.7(f)(iii).

         (iii)   The sale of the Excess Shares by the Paying Agent shall be
    executed on the NYSE through one or more member firms of the NYSE and shall
    be executed in round lots to the extent practicable.  The Paying Agent
    shall use reasonable efforts to complete the sale of the Excess Shares as
    promptly following the Effective Time as, in the Paying Agent's sole
    judgment, is practicable consistent with obtaining the best execution of
    such sales in light of prevailing market conditions.  Until the net
    proceeds of such sale or sales have been distributed to the holders of
    Certificates formerly representing Company Common Shares, the Paying Agent
    shall hold such proceeds in trust for such holders (the "Excess Shares
    Trust").  Parent shall pay all commissions, transfer taxes and other out-
    of-pocket transaction costs, including the expenses and compensation of the
    Paying Agent, incurred in connection with such sale of the Excess Shares.

         (iv)    The Paying Agent shall determine the portion of the Excess
    Shares Trust to which each former holder of Company Common Shares is
    entitled, if any, by multiplying the amount of the aggregate net proceeds
    comprising the Excess Shares Trust by the quotient (rounded to the nearest
    one hundred thousandth) of the number of Parent Common Shares such former
    holder of Company Common Shares would have been entitled to receive
    pursuant to Section 1.6 hereof but for the provisions of Section 1.7(f)
    hereof divided by the aggregate number of Excess Shares. As soon as
    practicable after such determination, the Paying Agent shall make available
    such amounts to such holders of Certificates formerly representing Company
    Common Shares subject to and in accordance with the terms of this
    Agreement.

    (g)  Withholding Rights.  Parent or the Paying Agent shall be entitled to
deduct and withhold from the Merger Consideration otherwise payable pursuant to
this Agreement to any holder of Company Common Shares such amounts as Parent or
the Paying Agent is required to deduct and withhold with respect to the making
of such payment under the Internal Revenue Code of 1986, as amended (the
"Code"), or any provision of state, local or foreign tax law.  Any such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Company Common Shares in respect of which such
deduction and withholding was made by Parent or the Paying Agent.

    SECTION 1.8  Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of





                                       6
<PAGE>   12
transfers of the Company Common Shares thereafter on the records of the Company
or the Surviving Corporation.  If, after the Effective Time, Certificates are
presented to the Surviving Corporation for any reason, they shall be canceled
and exchanged as provided in this Article I.

    SECTION 1.9  No Further Ownership Rights in Company Common Shares.  The
Merger Consideration delivered upon the surrender for exchange of Certificates
in accordance with the terms hereof shall be deemed to have been issued and/or
paid, as the case may be, in full satisfaction of all rights pertaining to the
Company Common Shares formerly represented by such Certificates.

    SECTION 1.10     Lost, Stolen or Destroyed Certificates.  In the event any
Certificates shall have been lost, stolen or destroyed, the Paying Agent shall
deliver in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, the Merger
Consideration as may be required pursuant to Section 1.6; provided, however,
that Parent may, in its discretion and as a condition precedent to the issuance
of the Merger Consideration, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably
direct as indemnity against any claim that may be made against Parent or the
Paying Agent with respect to the Certificates alleged to have been lost, stolen
or destroyed.

    SECTION 1.11     Taking of Necessary Action; Further Action.  Subject to
Sections 1.12 and 5.2 and Article VII hereof, each of Parent, Acquisition and
the Company will take all such reasonable and lawful action as may be necessary
or appropriate in order to effectuate the Merger in accordance with this
Agreement as promptly as possible.  If, at any time after the Effective Time,
any such further action is necessary or desirable to carry out the purposes of
this Agreement and to vest the Surviving Corporation with full right, title and
possession to all assets, property, rights, privileges, powers and franchises
of the Company and Acquisition, the officers and directors of the Company and
Acquisition immediately prior to the Effective Time are fully authorized in the
name of their respective corporations or otherwise to take, and will take, all
such lawful and necessary action.

    SECTION 1.12     Stockholders' Meeting.  The Company, acting through the
Board, shall in accordance with applicable law and subject to the fiduciary
duties of the Board (as determined by the Board after consultation with
counsel), as soon as practicable following the date of this Agreement:

         (a) duly call, give notice of, convene and hold an annual or special
    meeting of its stockholders on a date to be determined by the Board and
    reasonably satisfactory to Parent, but in no event later than March 31,
    1999 (the "Special Meeting") for the purpose  of considering and taking
    action upon this Agreement;





                                       7
<PAGE>   13
         (b) include in the Proxy Statement/Prospectus (as defined in Section
    4.1) the  recommendation of the Board that stockholders of the Company vote
    in favor of the adoption of this Agreement; and

         (c) use its reasonable best efforts (i) to obtain and furnish the
    information required to be included by it in the Proxy Statement/Prospectus
    and, after consultation with Parent, respond promptly to any comments made
    by the Securities and Exchange Commission (the "SEC") with respect to the
    Proxy Statement/Prospectus and any preliminary version thereof and cause
    the Proxy Statement/Prospectus to be mailed to its stockholders at the
    earliest practicable time and (ii) to obtain the necessary approvals by its
    stockholders of this Agreement.

At the Special Meeting, Parent and Acquisition will vote all Company Common
Shares owned by them in favor of the adoption of this Agreement.

    SECTION 1.13     Material Adverse Effect.  When used in connection with the
Company or any of its subsidiaries, or Parent or any of its subsidiaries, as
the case may be, the term "Material Adverse Effect" means any change, effect or
circumstance that is materially adverse to the business, financial condition or
results of operations of the Company and its subsidiaries, or Parent and its
subsidiaries, as the case may be, in each case taken as a whole, other than any
such changes, effects or circumstances:  (i) set forth or contemplated by the
written disclosure schedule delivered on or prior to the date hereof by the
Company to Parent (the "Company Disclosure Schedule") or the written disclosure
schedule delivered on or prior to the date hereof, by Parent to the Company
(the "Parent Disclosure Schedule"), as the case may be; (ii) set forth or
described in the Company Filed SEC Reports (as defined in Section 2.8) or the
Parent Filed SEC Reports (as defined in Section 3.8), as the case may be; or
(iii) affecting the scheduled intercity bus transportation  industry or the
North American economy generally.


                                   ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    Except as disclosed in the Company Filed SEC Reports or as set forth in the
Company Disclosure Schedule, the Company hereby represents and warrants to
Parent and Acquisition that:

    SECTION 2.1  Organization and Qualification; Subsidiaries.  The Company and
each of its significant subsidiaries (as that term is defined in Rule 1-02 of
Regulation S-X) is a corporation or other legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization and has the corporate or





                                       8
<PAGE>   14
similar power and authority necessary to own, lease and operate the properties
it purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power and authority would not have a Material
Adverse Effect.  The Company and each of its significant subsidiaries is duly
qualified or licensed to do business, and is in good standing (with respect to
jurisdictions that recognize such concept), in each jurisdiction where the
character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would
not in the aggregate have a Material Adverse Effect.  A true and complete list
of all of the Company's subsidiaries, together with the jurisdiction of
organization of each subsidiary and the percentage of each significant
subsidiary's outstanding capital stock owned by the Company or another
subsidiary, is set forth in Section 2.1 of the Company Disclosure Schedule.
Except as set forth in Section 2.1 of the Company Disclosure Schedule, the
Company does not directly or indirectly own any equity or similar interest in,
or any interest convertible into or exchangeable or exercisable for, any equity
or similar interest in, any corporation, partnership, joint venture or other
business association or legal entity, with respect to which interest the
Company or any of its subsidiaries has invested or is required to invest
$1,000,000 or more, excluding securities held by trusteed benefit plans and
trusts.

    SECTION 2.2  Certificate of Incorporation and By-Laws.  The Company has
heretofore furnished to Parent a complete and correct copy of its Certificate
of Incorporation and By-Laws, and has furnished or made available to Parent the
Certificate of Incorporation and By-Laws (or equivalent organizational
documents) of each of its subsidiaries (the "Subsidiary Documents"), in each
case as amended to the date of this Agreement.  Such Certificate of
Incorporation, By-Laws and Subsidiary Documents are in full force and effect.
Neither the Company nor any of its subsidiaries is in violation of any of the
provisions of such documents.

    SECTION 2.3  Capitalization.  The authorized capital stock of the Company
consists of (i) 100,000,000 Company Common Shares and (ii) 10,000,000 shares of
preferred stock, $.01 par value per share, including (A) 2,760,000 Company
Preferred Shares, and (B) 2,000,000 shares of Series A Junior Preferred Stock,
$.01 par value.  As of September 30, 1998: (i) 60,137,650 Company Common Shares
were issued and outstanding, all of which are validly issued, fully paid and
nonassessable, and 109,192 Company Common Shares were held in treasury, (ii) no
Company Common Shares were held by subsidiaries of the Company, (iii) 6,769,021
Company Common Shares were reserved for future issuance pursuant to outstanding
stock options granted under the Company Stock Option Plans (as defined in
Section 4.9), 12,307,692 Company Common Shares were reserved for issuance upon
conversion of the Company Preferred Shares and 792,242 Company Common Shares
were reserved for issuance upon conversion of the Company's 8 1/2% Convertible
Subordinated Debentures due March 31, 2007, (iv) 2,400,000 Company Preferred
Shares were issued and outstanding, and  (v) no shares





                                       9
<PAGE>   15
of the Company's Series A Junior Preferred Stock were issued and outstanding.
No material change in such capitalization has occurred between September 30,
1998 and the date hereof.  Except as set forth in this Section 2.3 or Section
2.11 or in the related sections of the Company Disclosure Schedule, there are
no options, warrants or other similar rights, agreements, arrangements or
commitments of any character relating to the issued or unissued capital stock
of the Company or any of its subsidiaries or obligating the Company or any of
its subsidiaries to issue or sell any shares of capital stock of, or other
equity interests in, the Company or any of its subsidiaries.  All of the
Company Common Shares subject to issuance as aforesaid, upon issuance on the
terms and conditions specified in the instruments pursuant to which they are
issuable, shall be duly authorized, validly issued, fully paid and
nonassessable.  Except as disclosed in Section 2.3 of the Company Disclosure
Schedule, there are no obligations, contingent or otherwise, of the Company or
any of its subsidiaries to repurchase, redeem or otherwise acquire any Company
Common Shares or Company Preferred Shares or the capital stock of any
subsidiary or to provide funds to or make any investment (in the form of a
loan, capital contribution or otherwise) in any such subsidiary or any other
entity other than guarantees of leases and bank obligations of subsidiaries
entered into in the ordinary course of business.  Except as set forth in
Sections 2.1 and 2.3 of the Company Disclosure Schedule, all of the outstanding
shares of capital stock of each of the Company's subsidiaries is duly
authorized, validly issued, fully paid and nonassessable, and all such shares
are owned by the Company or another subsidiary of the Company free and clear of
all security interests, liens, pledges, agreements, limitations in the
Company's voting rights, charges or other encumbrances of any nature
whatsoever.

    SECTION 2.4  Authority Relative to this Agreement.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to perform its obligations hereunder and to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement by the
Company and the consummation by the Company of the transactions contemplated
hereby have been duly and validly authorized by all necessary corporate action,
and no other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or to consummate the transactions so contemplated
(other than the adoption of this Agreement by the holders of at least a
majority of the outstanding Company Common Shares and the outstanding Company
Preferred Shares (voting together as one class) entitled to vote in accordance
with the Delaware Law and the Company's Certificate of Incorporation and By-
Laws).  As of the date of this Agreement, the Board of Directors of the Company
has determined that the Merger and the transactions contemplated thereby, upon
the terms and subject to the conditions of this Agreement, are fair to and in
the best interests of the Company and its stockholders.  This Agreement has
been duly and validly executed and delivered by the Company and, assuming the
due authorization, execution and delivery by Parent and Acquisition, and
adoption of the Agreement by the requisite vote of the stockholders of the
Company, constitutes a valid and binding obligation of the Company enforceable
against the Company in accordance with its terms.

Schedule, the execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, (i) conflict
with or violate the Certificate of Incorporation or By-Laws of the Company,
(ii) conflict with or violate any law, rule, regulation, order, judgment or
decree in effect as of the date of this Agreement applicable to the Company or
any of its subsidiaries or by which its or any of their respective properties

(or an event that with notice or lapse of time or both would become a default)
under, or impair the Company's or any of its subsidiaries' rights or alter the
rights or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any Material Contract,
or result in the creation of a lien or encumbrance on any of the properties or
assets of the Company or any of its subsidiaries pursuant to any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Company or any of its subsidiaries
is a party or by which the Company or any of its subsidiaries or its or any of
their respective properties is bound or affected, except in any such case for
any such conflicts, violations, breaches, defaults or other occurrences that
would not have a Material Adverse Effect.

    (c)    Except as set forth in Section 2.5(c) of the Company Disclosure
Schedule, the execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, require any

the Merger, or otherwise prevent or delay the





                                       11
<PAGE>   17
Company from performing its obligations under this Agreement, and would not
otherwise in the aggregate have a Material Adverse Effect.

    SECTION 2.6  Compliance.

    (a)   Except as disclosed in Section 2.6(a) of the Company Disclosure

where the failure to be in such compliance would not, individually or in the
aggregate, have a Material Adverse Effect.

    SECTION 2.7  SEC Filings; Financial Statements.

    (a)    Except as set forth in Section 2.7 of the Company Disclosure
Schedule, the Company has filed all forms, reports and documents required to be
filed with the SEC and has made available to Parent (i) its Annual Reports on

were filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a

consolidated financial position of the Company and its subsidiaries as at the
respective dates thereof and the consolidated results of its operations and
cash flows for the periods indicated, except that the unaudited interim
financial statements were or are subject to normal and recurring year-end
adjustments which were not or are not expected to be material in amount.

    SECTION 2.9  No Undisclosed Liabilities.  Except as is disclosed in Section

    SECTION 2.13     Restrictions on Business Activities.  Except for this
Agreement or as set forth in Section 2.13 of the Company Disclosure Schedule,
there is no agreement, judgment, injunction, order or decree binding upon and
specifically applicable to the Company or any of its subsidiaries which has or
could reasonably be expected to have the effect of prohibiting or impairing any
material business practice of the Company or any of its subsidiaries, any
acquisition of property by the Company or any of its subsidiaries or the
conduct of business by the Company or any of its subsidiaries as currently
conducted or as proposed to be conducted by the Company, except for any
prohibitions or impairments as would not in the aggregate have a Material
Adverse Effect.

    SECTION 2.14     Taxes.

    (a)  For purposes of this Agreement, (i) "Tax" or "Taxes" shall mean taxes,
fees, levies, duties, tariffs, imposts, and governmental impositions or charges
of any kind in the nature of (or similar to) taxes, payable to any federal,
state, local or foreign taxing authority, including (without limitation)
income, franchise, profits, gross receipts, ad valorem, net worth, value added,
sales, use, service, real or personal property, special assessments, capital
stock, license, payroll, withholding, employment, social security, workers'
compensation, unemployment compensation, utility, severance, production,
excise, stamp, occupation premiums, windfall profits, transfer and gains taxes
and interest, penalties, additional taxes and additions to tax imposed with
respect thereto and (ii) "Tax Returns" shall mean returns, reports, estimates
and information returns and statements with respect to Taxes required to be

    (b)  Other than as disclosed in Section 2.14(b) of the Company Disclosure
Schedule:

         (i) The Company and each of its subsidiaries (for such periods as each
    subsidiary was owned, directly or indirectly, by the Company), have filed
    all federal income Tax Returns and all other material Tax Returns required
    to be filed by it (taking into account all applicable extensions), and all
    such Tax Returns are complete and correct in all material respects, or
    requests for extensions to file such Tax Returns have been timely filed,
    granted and have not expired, except to the extent that such failures to
    file, to be complete or correct or to have extensions granted that remain
    in effect, individually or in the aggregate, would not have a Material
    Adverse Effect on the Company.  The Company and each of its subsidiaries
    has paid, or the Company has paid or caused to be paid on its subsidiaries'
    behalf, all Taxes shown as due on such Tax Returns and all material Taxes
    for which no Tax Return was required to be filed.  The most recent
    financial statements contained in the Company SEC Reports reflect an
    adequate reserve in accordance with GAAP for all Taxes payable by the
    Company and its subsidiaries





                                       16

    financial statements.

         (ii)    No material Tax Return of the Company or any of its
    subsidiaries is under audit or examination by any taxing authority or the
    subject of any pending court proceeding, and no written notice of such an
    audit or examination has been received by the Company or any of its
    subsidiaries.  Each material deficiency resulting from any audit or
    examination relating to Taxes by any taxing authority has been paid, except
    for deficiencies being contested in good faith.  No material issue relating
    to Taxes were raised in writing by the relevant taxing authority during any
    presently pending audit or examination.  None of the federal income Tax
    Returns of the Company or any of its subsidiaries consolidated in such Tax
    Returns for any period have been examined by the IRS.

         (iii)   There is no agreement or other document extending, or having
    the effect of extending, the period of assessment or collection of any
    material Taxes and no power of attorney with respect to any material Taxes
    has been executed or filed with any taxing authority.

         (iv)    No material liens for Taxes exist with respect to any assets
    or properties of the Company or any of its subsidiaries, except for
    statutory liens for Taxes not yet due.

         (v) The accruals and reserves for Taxes (including deferred taxes)
    reflected in the 1998 Company Balance Sheet are in all material respects
    adequate (and until the Closing Date will continue to be adequate) to cover
    all Taxes required to be accrued through the date thereof (including
    interest and penalties, if any, thereon and Taxes being contested) in
    accordance with generally accepted accounting principles.

         (vi)    The Company and its subsidiaries have complied in all material
    respects with all applicable laws, rules and regulations relating to the
    payment and withholding of Taxes and have timely withheld from employee
    wages and paid over to the proper governmental authorities all amounts
    required to be so withheld and paid over under all applicable laws.

         (vii)   Neither the Company nor any of its subsidiaries has engaged in
    any inter-company transactions within the meaning of Treasury Regulation
    Section 1.1502-13 for which any income or gain will be recognized (as a
    result of the Merger or otherwise) during any taxable period ending on or
    before the Closing Date.

2.15 of the Company Disclosure Schedule, neither the Company nor any of its
subsidiaries owns any material patents, trademarks, trade names, service marks,
copyrights, and any applications therefor ("Intellectual Property").  Except as
set forth in Section 2.15 of the Company Disclosure Schedule, the Company

delivery of this Agreement, the Company has taken all action necessary in order
to (i) render the Amended and Restated Rights Agreement dated as of April 18,

between the Company and Bear Stearns pursuant to which such firm would be
entitled to any payment relating to the transactions contemplated hereunder.

    SECTION 2.19     Section 203 of the Delaware Law Not Applicable.  The Board
has taken all actions so that the provisions contained in Section 203 of the
Delaware Law applicable to a "business combination" (as defined in Section 203)
will not apply to the execution, delivery or performance of this Agreement or
the consummation of the Merger or the other transactions contemplated by this
Agreement.

                                  ARTICLE III

            REPRESENTATIONS AND WARRANTIES OF PARENT AND ACQUISITION

    Except as disclosed in the Parent Filed SEC Reports or as set forth in the
Parent Disclosure Schedule, Parent and Acquisition hereby, jointly and
severally, represent and warrant to the Company that:

    SECTION 3.1  Organization and Qualification; Subsidiaries.  Parent and each
of its significant subsidiaries (as that term is defined in Rule 1-02 of
Regulation S-X) is a corporation or other legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization and has the corporate or similar power and authority necessary to
own, lease and operate the properties it purports to own, operate or lease and
to carry on its business as it is now being conducted, except where the failure
to be so organized, existing and in good standing or to have such power and
authority would not have a Material Adverse Effect.  Parent and each of its
significant subsidiaries is duly qualified or licensed to do business, and is
in good standing (with respect to jurisdictions that recognize such concept),
in each jurisdiction where the character of its properties owned, leased or
operated by it or the nature of its activities makes such qualification or
licensing necessary, except for such failures to be so duly qualified or
licensed and in good standing that would not in the aggregate have a Material
Adverse Effect.

    SECTION 3.2  Certificate and Articles of Amalgamation and By-Laws.  Parent
has heretofore furnished to the Company a complete and correct copy of its
Certificate and Articles of Amalgamation and By-Laws, in each case as amended
to the date of this Agreement.  Such Certificate and Articles of Amalgamation
and By-Laws are in full force and effect.  Parent is not in violation of any of
the provisions of  such documents.

    SECTION 3.3  Capitalization.  As of September 30, 1998, the authorized
capital stock of Parent consisted of (i) an unlimited number of Parent Common
Shares, of which 330,156,836 shares were issued and outstanding; (ii) an
unlimited  number of Preference Shares, of which 558,070 shares of 5%
Cumulative Convertible First Preference Shares Series G (the "Parent Preferred
Shares") were issued and outstanding.  As of September 30, 1998, 8,722,800
Parent Common Shares were reserved for issuance upon the exercise of stock
options, 575,999 Parent Common Shares were reserved for issuance upon the
exercise of certain warrants, and no Parent Common Shares were held by Parent
in its treasury.  No material change in such capitalization has occurred
between September 30, 1998 and the date hereof.  All outstanding Parent Common
Shares and Parent Preferred Shares are validly issued, fully paid, non-
assessable and free of preemptive rights.  Except as set forth above, there are
no options, warrants or other rights, agreements, arrangements or commitments
of any character relating to the issued or unissued capital stock of Parent or
any of its subsidiaries or obligating Parent or any of its






                                       19
<PAGE>   25
subsidiaries to issue or sell any shares of capital stock of, or other equity
interests in, Parent or any of its subsidiaries.  Except for Parent's market
support obligations to purchase up to 20,000 Parent Preferred Shares per year at
a price of up to $20 per share, there are no obligations, contingent or
otherwise, of Parent to repurchase, redeem or otherwise acquire any of the
capital stock of Parent or the capital stock of any subsidiary or to provide
funds to or make any investment (in the form of a loan, capital contribution or
otherwise) in any such subsidiary other than guarantees of bank obligations of
subsidiaries entered into in the ordinary course of business.  All of the
outstanding shares of capital stock of each of Parent's subsidiaries are duly
authorized, validly issued, fully paid and nonassessable, and all such shares
are owned by Parent or another subsidiary of Parent free and clear of all
security interests, liens, claims, pledges, agreements, limitations on Parent's
voting rights, charges or other encumbrances of any nature whatsoever.  The
Parent Common Shares issuable in connection with the Merger are duly authorized
and reserved and, when issued in accordance with the terms of this Agreement,
will be validly issued, fully paid, nonassessable and free of preemptive rights.

    SECTION 3.4  Authority Relative to this Agreement.  Each of Parent and
Acquisition has all necessary corporate power and authority to execute and
deliver this Agreement and to perform its obligations hereunder and to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by Parent and Acquisition and the consummation by Parent and
Acquisition of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of Parent and
Acquisition, and no other corporate proceedings on the part of Parent or
Acquisition are necessary to authorize this Agreement or to consummate the
transactions contemplated hereby.  As of the date of this Agreement, the Board
of Directors of Parent has determined that the Merger, upon the terms and
subject to the conditions of this Agreement, is advisable and in the best
interest of Parent's stockholders.  This Agreement has been duly and validly
executed and delivered by Parent and Acquisition and adopted by Parent as the
sole stockholder of Acquisition and, assuming the due authorization, execution
and delivery by the Company and adoption of the Agreement by the requisite vote
of the stockholders of the Company, constitutes a valid and binding obligation
of Parent and Acquisition enforceable against each of them in accordance with
its terms.

    SECTION 3.5  No Conflict, Required Filings and Consents.

    (a)  Except as set forth in Section 3.5(a) of Parent Disclosure Schedule,

conflict with or violate the Certificate and Articles of Amalgamation,
Certificate of Incorporation or By-Laws (or other constituent instruments) of
Parent or Acquisition, (ii) conflict with or violate any law, rule, regulation,
order, judgment or decree in effect as of the date of this Agreement applicable

a default (or an event that with notice or lapse of time or both would become a
default) under, or impair Parent's or any of its subsidiaries' rights or alter
the rights or obligations of any third party under, or give to others any
rights of termination, amendment, acceleration or cancellation of, any Material
Parent Contract (as defined in Section 3.6), or result in the creation of a
lien or encumbrance on any of the properties or assets of Parent or any of its
subsidiaries pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Parent or any of its subsidiaries is a party or by which Parent or any
of its subsidiaries or its or any of their respective properties are bound or
affected, except in any such case for any such conflicts, violations, breaches,
defaults or other occurrences that would not in the aggregate have a Material
Adverse Effect.

    (b)  Except as set forth in Section 3.5(b) of the Parent Disclosure
Schedule, the execution and delivery of this Agreement by Parent and
Acquisition does not, and the performance of this Agreement by Parent and
Acquisition will not, require any consent, approval, authorization or permit

the filing and recordation of appropriate merger or other documents as required
by the Delaware Law, (ii) the applicable requirements of the STB, and (iii)
where the failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, would not prevent or delay
consummation of the Merger, or otherwise prevent or delay Parent or Acquisition

not otherwise in the aggregate have a Material Adverse Effect.

respective properties is bound or affected or (ii) any agreement (A) required
to be filed as "material contracts" with the SEC pursuant to the requirements
of the Exchange Act or (B) under which the consequences of a default,
nonrenewal or termination would have a Material Adverse Effect on the Parent
(collectively, the "Material Parent Contracts") to which Parent or any of its
subsidiaries is a party or by which Parent or any of its subsidiaries or its or
any of their respective properties is bound or affected, except for any such
conflicts, defaults or violations which would not in the aggregate have a
Material Adverse Effect.

amended or superseded by a filing prior to the date of this Agreement, then on

proposed to be conducted by Parent, except for any prohibitions or impairments
as would not in the aggregate have a Material Adverse Effect.

    SECTION 3.13     No Prior Activities; Financing.

    (a)  Acquisition was formed solely for the purpose of engaging in the
transactions contemplated by this Agreement.  As of the date hereof and the
Effective Time, except for obligations or liabilities incurred in connection
with its incorporation or organization and the transactions contemplated by
this Agreement and except for this Agreement and any other agreements or
arrangements contemplated by this Agreement, Acquisition has not and will not
have incurred, directly or indirectly, through any subsidiary or affiliate, any
obligations





                                       23
<PAGE>   29
or liabilities or engaged in any business activities of any type or kind
whatsoever or entered into any agreements or arrangements with any person.

    (b)  Acquisition has (and Parent will cause Acquisition to have) available
to it funds necessary to satisfy its obligations hereunder including, without
limitation, the obligation to pay the Cash Merger Consideration pursuant to the
Merger and to pay all related fees and expenses in connection with the Merger.

    SECTION 3.14     Taxes.  Other than as disclosed in Section 3.14 of the
Parent Disclosure Schedule:

    (a)  Parent and each of its subsidiaries (for such periods as each
subsidiary was owned, directly or indirectly, by Parent), have filed all
federal income Tax Returns and all other material Tax Returns required to be
filed by it, (taking into account all applicable extensions) and all such Tax
Returns are complete and correct in all material respects, or requests for
extensions to file such Tax Returns have been timely filed, granted and have
not expired, except to the extent that such failures to file, to be complete or
correct or to have extensions granted that remain in effect, individually or in
the aggregate, would not have a Material Adverse Effect on Parent.  Parent and
each of its subsidiaries has paid, or the Parent has paid or caused to be paid
on its subsidiaries' behalf, all Taxes shown as due on such Tax Returns and all
material Taxes for which no Tax Return was required to be filed.  The most
recent financial statements contained in the Parent Filed SEC Reports reflect
an adequate reserve in accordance with Canadian generally accepted accounting
principles for all Taxes payable by Parent and its subsidiaries for all taxable
periods and portions thereof through the date of such financial statements.

    (b)  No material Tax Return of Parent or any of its subsidiaries is under
audit or examination by any taxing authority or the subject of any pending
court proceeding, and no written notice of such an audit or examination has
been received by Parent or any of its subsidiaries.  Each material deficiency
resulting from any audit or examination relating to Taxes by any taxing
authority has been paid, except for deficiencies being contested in good faith.
No material issue relating to Taxes were raised in writing by the relevant
taxing authority during any presently pending audit or examination.  None of
the federal income Tax Returns of Parent or any of its subsidiaries
consolidated in such Tax Returns for any period have been examined by the IRS.

    (c)  There is no agreement or other document extending, or having the
effect of extending, the period of assessment or collection of any Taxes and no
power of attorney with respect to any Taxes has been executed or filed with any
taxing authority.

    (d)  No material liens for Taxes exist with respect to any assets or
properties of Parent or any of its subsidiaries, except for statutory liens for
Taxes not yet due.





                                       24
<PAGE>   30
    (e)  The accruals and reserves for Taxes (including deferred taxes)
reflected in the 1998 Parent Balance Sheet are in all material respects
adequate (and until the Closing Date will continue to be adequate) to cover all
Taxes required to be accrued through the date thereof (including interest and
penalties, if any, thereon and Taxes being contested) in accordance with
Canadian generally accepted accounting principles.

    (f)  Parent and its subsidiaries have complied in all material respects
with all applicable laws, rules and regulations relating to the payment and
withholding of Taxes and have timely withheld from employee wages and paid over
to the proper governmental authorities all amounts required to be so withheld
and paid over under all applicable laws.

    (g)  Neither Parent nor any of its subsidiaries has engaged in any inter-
company transactions within the meaning of Treasury Regulation Section
1.1502-13 for which any income or gain will be recognized (as a result of the
Merger or otherwise) during any taxable period ending on or before the Closing
Date.

    SECTION 3.15     Intellectual Property.  Except as set forth in Section
3.15 of the Parent Disclosure Schedule, neither Parent nor any of its
Subsidiaries owns any material Intellectual Property.  Except as set forth in
Section 3.15 of the Parent Disclosure Schedule, Parent and/or each of its
subsidiaries owns, or is licensed or otherwise possesses legally enforceable
rights to use all Intellectual Property used in the business of Parent and its
subsidiaries as currently conducted, except as would not have a Material
Adverse Effect.

    SECTION 3.16     Brokers.  No broker, finder or investment banker (other
than Merrill Lynch, Pierce, Fenner & Smith Incorporated) is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of Parent.

    SECTION 4.12     Indemnification and Insurance.

    (a)  The Certificate of Incorporation and By-Laws of the Surviving
Corporation shall contain the provisions with respect to indemnification,
exculpation and advancement of expenses set forth in the Certificate of
Incorporation and By-Laws of the Company,





                                       29
<PAGE>   35
which provisions shall not be amended, repealed or otherwise modified for a
period of three years from the Effective Time in any manner that would
adversely affect the rights thereunder of individuals who at the Effective Time
were present or former directors, officers, employees or agents of the Company,
unless such modification is required by law.

    (b)  The Company shall, to the fullest extent permitted under applicable
law or under the Company's Certificate of Incorporation or By-Laws and
regardless of whether the Merger becomes effective, indemnify and hold
harmless, and, after the Effective Time, the Parent and the Surviving
Corporation shall, jointly and severally, to the fullest extent permitted under
applicable law or under the Surviving Corporation's Certificate of
Incorporation or By-Laws, indemnify and hold harmless, each present and former
director, officer or employee of the Company or any of its subsidiaries
(collectively, the "Indemnified Parties") against any costs or expenses
(including attorneys' fees), judgments, fines, losses, claims, damages and
liabilities incurred in connection with, and amounts paid in settlement of, any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative and wherever asserted, brought or filed, (x)
arising out of or pertaining to the transactions contemplated by this Agreement
or (y) otherwise with respect to any acts or omissions or alleged acts or
omissions occurring at or prior to the Effective Time, to the same extent as
provided in the respective Certificate of Incorporation or By-Laws of the
Company or the subsidiaries or any applicable contract or agreement as in
effect on the date of this Agreement, in each case for a period of five years
after the date hereof.  In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) any counsel retained by the Indemnified Parties for any period after
the Effective Time shall be reasonably satisfactory to the Surviving
Corporation, (ii) after the Effective Time, the Surviving Corporation shall
(and Parent shall cause the Surviving Corporation to) pay the reasonable fees
and expenses of such counsel, promptly after statements therefor are received,
and (iii) the Surviving Corporation will cooperate in the defense of any such
matter; provided, however, that the Surviving Corporation shall not be liable
for any settlement effected without its written consent (which consent shall
not be unreasonably withheld or delayed); and provided, further, that, in the
event that any claim or claims for indemnification are asserted or made within
such five-year period, all rights to indemnification in respect of any such
claim or claims shall continue until the disposition of any and all such
claims.  The Indemnified Parties as a group may retain only one law firm to
represent them with respect to any single action unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties.  The
indemnity agreements of Parent and the Surviving Corporation in this Section
4.12(b) shall extend on the same terms to, and shall inure to the benefit of
and shall be enforceable by, each person or entity who controls, or in the past
controlled, any present or former director, officer or employee of the Company
or any of its subsidiaries.

    (c)  The Surviving Corporation shall (and Parent shall cause the Surviving
Corporation to) honor and fulfill in all respects the obligations of the
Company pursuant to





                                       30
<PAGE>   36
indemnification agreements with the Company's directors and officers existing
at or before the Effective Time.

    (d)  For a period of five years after the Effective Time, Parent shall
cause the Surviving Corporation to maintain in effect, directors' and officers'
liability insurance covering those persons who are currently covered by the
Company's directors' and officers' liability insurance policy (a copy of which
has been made available to Parent) on terms (including the amounts of coverage
and the amounts of deductibles, if any) that are comparable to the terms now
applicable to directors and officers of Parent, or, if more favorable to the
Company's directors and officers, the terms now applicable to them under the
Company's current policies; provided, however, that in no event shall Parent or
the Surviving Corporation be required to expend in excess of 300% of the annual
premium currently paid by the Company for such coverage; and provided further,
that if the premium for such coverage exceeds such amount, Parent or the
Surviving Corporation shall purchase a policy if available with the greatest
coverage available for such 300% of the annual premium.

    (e)  From and after the Effective Time, Parent shall guarantee the
obligations of the Surviving Corporation under this Section 4.12.

    (f)  This Section 4.12 shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, the Surviving Corporation
and the Indemnified Parties, shall be binding on all successors and assigns of
the Surviving Corporation and shall be enforceable by the Indemnified Parties.
In the event that Parent or the Surviving Corporation or any of their
successors or assigns (i) consolidates or merges into any other person or
entity and shall not be the continuing or surviving corporation or entity in
such consolidation or merger or (ii) transfers all or substantially all of its
properties and assets  to any person or entity, then and in such case, proper
provisions shall be made so that the successors and assigns of Parent or the
Surviving Corporation (as the case may be) assume the obligations of Parent and
the Surviving Corporation set forth in this Section 4.12.

    SECTION 4.13     Continuation of Company Employee Plans.

    (a)  Except as may be otherwise required or permitted under any collective
bargaining agreement to which the Company is a party, the Surviving Corporation
will (and Parent shall cause the Surviving Corporation to), for a period of not
less than 12 months following the Effective Time, continue without amendment or
change, except changes which increase compensation or benefits paid or payable
thereunder or as may be required by law, the Company Employee Plans and other
policies, practices, programs and arrangements which provide compensation or
benefits to employees of the Company or its subsidiaries.  Notwithstanding the
foregoing, (i) the Surviving Corporation may replace any of such individual
plans, policies, practices, programs or arrangements with another





                                       31
<PAGE>   37
plan, policy, practice, program or arrangement providing, in the aggregate, not
less than a substantially equivalent level of compensation or benefits, as the
case may be, and (ii) the Surviving Corporation shall not be required to
maintain any Company Employee Plan that provides for the issuance of Company
Common Shares or any other stock-based award plan or program ("Stock Plans");
provided that Parent replaces such Stock Plans with another plan, policy,
practice, program or arrangement that the Board of Directors of the Surviving
Corporation determines in good faith provides comparable incentive compensation
opportunities.

    (b)  Except as may be expressly provided in a valid written waiver
voluntarily signed by an affected employee, the Company will honor and, on and
after the Effective Time, Parent will cause the Surviving Corporation to honor
in accordance with the terms thereof, without offset, deduction, counterclaim,
interruption or deferment (other than withholdings under applicable law) all
Company Benefit Plans, including all employment, change-in-control, severance,
termination, consulting and unfunded retirement or benefit agreements to which
the Company or any of its subsidiaries is a party.  For the purpose of any such
policy, practice, program or arrangement that contains a provision relating to
a change in control of the Company, Parent acknowledges that the consummation
of the Merger constitutes such a change in control.

    (c)  The Company and Parent will or may, as the case may be, take the
actions indicated in Section 4.13(c) of the Company Disclosure Schedule at or
prior to the times specified therein.

    SECTION 4.14     Notification of Certain Matters.  The Company shall give
prompt notice to Parent, and Parent shall give prompt notice to the Company, of
(i) the occurrence or nonoccurrence of any event the occurrence or
nonoccurrence of which would reasonably be expected to cause any representation
or warranty contained in this Agreement to be materially untrue or inaccurate,
or (ii) any failure of the Company, Parent or Acquisition, as the case may be,
materially to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; provided, however, that the
delivery of any notice pursuant to this Section 4.14 shall not limit or
otherwise affect the remedies available hereunder to the party receiving such
notice.

    SECTION 4.15     Further Action.  Upon the terms and subject to the
provisions hereof, each of the parties hereto shall use all reasonable efforts
to take, or cause to be taken, all actions, and to do, or cause to be done, all
other things necessary, appropriate or advisable to consummate and make
effective as promptly as practicable the Merger and the other transactions
contemplated by this Agreement, including (i) obtaining in a timely manner all
necessary waivers, consents and approvals from all federal, state, and foreign
courts and other governmental entities ("Governmental Entities") and to effect
all necessary registrations and filings, and the taking of all reasonable steps
as may be necessary, appropriate or advisable to obtain an approval or waiver
from, or to avoid an





                                       32
<PAGE>   38
action or proceeding by, any Governmental Entity, (ii) the obtaining of all
necessary consents, approvals or waivers from third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated by this Agreement, including seeking to have any stay
or temporary restraining order entered by any Governmental Entity vacated or
reversed, and (iv) the execution and delivery of any additional instruments
necessary to consummate the transactions contemplated by, and to fully carry
out the purposes of, this Agreement, and otherwise to satisfy or cause to be
satisfied all conditions precedent to its obligations under this Agreement,
including, on the part of Parent and Acquisition, entering into a voting trust
or similar agreement on customary terms to permit the consummation of the
Merger prior to the receipt of final approval from the STB of the transactions
contemplated by this Agreement.  The foregoing covenant shall not include any
obligations by Parent or the Company to agree to divest, abandon, license or
take similar action with respect to any assets of Parent or the Company except
such actions that would be immaterial to Parent and its subsidiaries or the
Company and its subsidiaries, in each case taken as a whole.

    SECTION 4.16      Public Announcements.  Parent and the Company shall
consult with each other before issuing any press release with respect to the
Merger or this Agreement and shall not issue any such press release or make any
similar public statement without the prior consent of the other party, which
shall not be unreasonably withheld; provided, however, that a party may,
without the prior consent of the other party, issue such press release or make
such public statement as may upon the advice of counsel be required by law or
the rules and regulations of the NYSE or the American Stock Exchange, if it has
used all reasonable efforts to consult with the other party.

    SECTION 4.17     Conveyance Taxes.  Parent and the Company shall cooperate
in the preparation, execution and filing of all returns, questionnaires,
applications, or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any
transfer, recording, registration and other fees, and any similar taxes which
become payable in connection with the transactions contemplated hereby that are
required or permitted to be filed on or before the Effective Time.

    SECTION 4.18     Company Preferred Shares.  Promptly after Effective Time,
Parent shall take such action as may be necessary to register under the
Securities Act the issuance, if any, of the Parent Common Shares issuable upon
conversion of the Company Preferred Shares after the Effective Time.

Company covenants and agrees that, during the period from the date of this

subsidiaries, (i) solicit or initiate any inquiries or proposals regarding any
merger, sale of substantial assets, sale of shares of capital stock (including

inquiries or proposals being referred to herein as an "Acquisition Proposal"),
(ii) engage in negotiations or discussions concerning, or provide any nonpublic
information to any person relating to, any Acquisition Proposal or (iii) agree
to approve or recommend any Acquisition Proposal.  Nothing contained in this

<PAGE>   42
its directors, officers, employees, representatives or agents to furnish
information, in each case pursuant to confidentiality agreements similar to the
one then in effect between the Company and Parent, and participating in
discussions or negotiations with any person or entity concerning any
Acquisition Proposal if the Board shall conclude after consultation with its
financial advisor, that such person or entity has made or is reasonably likely
to make a bona fide Acquisition Proposal for a transaction which it believes
may be more favorable to the Company's stockholders from a financial point of
view than the transactions contemplated hereby (any such Acquisition Proposal
being referred to herein as a "Superior Proposal").

    (b)  The Company shall promptly notify Parent after receipt of any written
Acquisition Proposal, or any modification of or amendment to any written
Acquisition Proposal, or any request for nonpublic information relating to the
Company or any of its subsidiaries in connection with an Acquisition Proposal

subsidiary by any person or entity that informs the Board that it is
considering making, or has made, an Acquisition Proposal. Such notice to Parent
shall be made orally and in writing, and shall indicate, if known, whether the
Company is providing or intends to provide the person making the Acquisition
Proposal with access to information concerning the Company as provided in
Section 5.2(c).

    (c)  The Company shall immediately cease and, subject to the terms hereof,
cause to be terminated any existing discussions or negotiations with any person
(other than Parent and Acquisition) conducted heretofore with respect to any
Acquisition Proposal in effect as of the date of this Agreement.  The Company

representative retained by the Company are aware of the restrictions described

prior to the Effective Time, notwithstanding adoption by the stockholders of
the Company or Parent:

    (a)  by mutual written consent duly authorized by the Boards of Directors
of Parent and the Company; or

    (b)  by either Parent or the Company if a court of competent jurisdiction
or governmental, regulatory or administrative agency or commission shall have
issued a nonappealable final order, decree or ruling or taken any other action
having the effect of permanently restraining, enjoining or otherwise
prohibiting the Merger (provided that the right to terminate this Agreement
under this Section 7.1(b) shall not be available to any party who has not
complied with its obligations under Section 4.5 and such noncompliance
materially contributed to the issuance of any such order, decree or ruling or
the taking of such action);

modify or change its approval or recommendation of this Agreement or the Merger
in a manner adverse to Parent;

<PAGE>   45
    (d)  by Parent or the Company, prior to the Effective Time (provided that
the terminating party is not then in material breach of any representation,
warranty, covenant or other agreement contained in this Agreement), (i) if any
representation or warranty of the Company or Parent, respectively, set forth in
this Agreement shall be untrue when made, or (ii) upon a breach in any material
respect of any covenant or agreement on the part of the Company or Parent,
respectively, set forth in this Agreement, in each case where such untruth or
breach would have a Material Adverse Effect on the Company or Parent, as the
case may be (either (i) or (ii) above being a "Terminating Breach"), provided,
that, if such Terminating Breach is curable by the Company or Parent, as the
case may be, through the exercise of its reasonable best efforts, then for so
long as the Company or Parent, as the case may be, continues to exercise such
reasonable best efforts, or if the Terminating Breach is cured, neither Parent
nor the Company, respectively, may terminate this Agreement under this Section
7.1(d);

    (e)  by Parent or the Company, prior to the Effective Time, if the Company
enters into a written agreement providing for the consummation of a transaction
that constitutes a Superior Proposal;

    (f)  by Parent or the Company, if the Special Meeting shall have been held
and this Agreement shall not have been adopted by the affirmative vote of the
holders of the requisite number of outstanding Company Common Shares and
outstanding Company Preferred Shares; or

    (g)  by Parent or the Company, if the Effective Time shall have not
occurred on or before March 31, 1999; provided, however, that neither Parent
nor the Company may terminate this Agreement pursuant to this Section 7.1(g) if
such party's failure to fulfill any of its obligations under this Agreement
shall be a reason that the Effective Time shall not have occurred on or before
such date.

    SECTION 7.2  Effect of Termination.  In the event of the termination of
this Agreement pursuant to Section 7.1, this Agreement shall forthwith become
void and there shall be no liability on the part of any party hereto or any of

Merger is consummated.

<PAGE>   46
    (b)  The Company shall pay Parent a fee of $20 million (the "Company Fee"),
upon the first to occur of the following events:

         (i) the termination of this Agreement pursuant to Section 7.1(e); or

         (ii)    the termination of this Agreement pursuant to Section 7.1(c)
    if prior to such termination a Superior Proposal has been made and is
    pending.

    (c)  The Company Fee payable pursuant to Section 7.3(b) shall be paid
within two (2) business days after the first to occur of any of the events
described in Section 7.3(b)(i) or (ii); provided, that, in no event shall the
Company be required to pay the Company Fee to Parent if, immediately prior to
the termination of this Agreement, the Company would have been entitled to
terminate this Agreement pursuant to Section 7.1(b), 7.1(g) or 7.1(d) on
account of a Terminating Breach by Parent.  The payment of the Company Fee
shall be Parent's sole and exclusive remedy for the event giving rise to the
payment of the Company Fee.

State of Delaware or any United States federal court sitting in the State of
Delaware, United States, and any appellate court from any thereof, and waives
any immunity from the jurisdiction of such courts over any suit, action or
proceeding that may be brought in connection with this Agreement. Parent
irrevocably waives, to the fullest extent permitted by law, any objection to
any suit, action or proceeding that may be brought in connection with this
Agreement in such courts whether on the grounds of venue, residence or domicile
or on the ground that any such suit, action or proceeding has been brought in
an inconvenient forum.  Parent agrees that final judgment in any such suit,
action or proceeding brought in such court shall be conclusive and binding upon
Parent and may be enforced in any court to the jurisdiction of which Parent is
subject by suit upon such judgment; provided that service of process is
effected upon Parent in the manner provided in this Agreement.

    (b)  Parent agrees that service of all writs, process and summonses in any
suit, action or proceeding brought in connection with this Agreement against
Parent in any court sitting in the State of Delaware, United States may be made
upon Schiff Hardin & Waite at 6600 Sears Tower, Chicago, Illinois 60606
(attention: Stephen J. Dragich), whom Parent irrevocably appoints as its
authorized agent for service for process.  Parent represents and warrants that
Schiff Hardin & Waite has agreed to act as Parent's agent for service of
process.  Parent agrees that such appointment shall be irrevocable so long as
this Agreement shall remain in effect or until the irrevocable appointment by
Parent of a successor as its authorized agent for such purpose and the
acceptance of such appointment by such successor.  Parent further agrees to
take any and all action, including the filing of any and all documents and
instruments, that may be necessary to continue such appointment in full force
and effect as aforesaid.  If Schiff Hardin & Waite shall cease to be Parent's
agent for service of process, Parent shall appoint without delay another such
agent and provide prompt written notice to the Company, to the extent known to
it, of such appointment.  With respect to any such action in any court of the
State of Delaware or any United States federal court in the State of Delaware,
United States, service of process upon Schiff Hardin & Waite, as the authorized
agent of Parent for service of process, and written notice of such service to
Parent, shall be deemed, in every respect, effective service of process upon
Parent.
