Dear Stockholder:
 
   
     You are invited to attend a very important special meeting of the
stockholders of Greyhound Lines, Inc. to be held on Tuesday, March 16, 1999.
    
 
     At the special meeting you will be asked to consider and vote upon a
proposal to adopt a merger agreement between Greyhound and Laidlaw Inc. If the
merger is completed, Greyhound will become a subsidiary of Laidlaw.
 
     Upon completion of the merger, the holders of Greyhound common stock will
receive $6.50 per share in cash. Under the terms of the merger agreement,
Laidlaw had the option to pay up to $4.00 of the merger consideration with
Laidlaw common shares. However, Laidlaw has irrevocably waived its right to do
so. As a result the merger consideration will be paid entirely in cash.
 
     The Greyhound preferred stock will remain outstanding after the merger
unless converted into Greyhound common stock prior to completion of the merger.
After the merger, the Greyhound preferred stock will no longer be convertible
into Greyhound common stock. Instead, each share of Greyhound preferred stock
will be convertible into the right to receive $33.33 in cash.
 
     The Board of Directors of Greyhound has, by the unanimous vote of the
directors present, determined that the merger is fair to and in the best
interests of Greyhound and its stockholders. ACCORDINGLY, THE BOARD HAS APPROVED
THE MERGER AGREEMENT AND RECOMMENDS THAT YOU VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT AT THE SPECIAL MEETING.
 
     In light of the importance of the proposed merger, we urge you to attend
the special meeting in person or participate by proxy. Whether or not you plan
to attend, after carefully reading and considering the accompanying materials,
please vote your shares as soon as possible. Your voting materials contain
detailed information on how to vote.
 
     The adoption of this merger agreement requires the approval of the holders
of a majority of the outstanding shares of Greyhound common stock and preferred
stock voting together as one class. Not voting is the same as a vote against the
merger. Regardless of the number of shares you own, your vote is important.
 
                                    Sincerely,
 
                                    /s/ CRAIG R. LENTZSCH
 
                                    Craig R. Lentzsch
                                    President and Chief Executive Officer
 
   
     This Proxy Statement is first being mailed to stockholders on or about
February 12, 1999.

     A special meeting of the holders of common stock and preferred stock of
Greyhound Lines, Inc., a Delaware corporation, will be held on Tuesday, March
16, 1999, at 9:00 a.m., local time, at the Hilton Dallas Parkway Hotel, 4801 LBJ
Freeway, in Dallas, Texas. The special meeting has been called for the following
purposes:
    
 
   -   To consider and vote upon a proposal to adopt the Amended and Restated
       Agreement and Plan of Merger among Greyhound, Laidlaw Inc. and Laidlaw
       Transit Acquisition Corp.
 
   -   If necessary, to approve any adjournment of the special meeting without
       further notice except by announcement at the special meeting.
 
     Following the merger, Greyhound will be a subsidiary of Laidlaw. The
proposed merger is described in detail in the accompanying Proxy Statement. A
copy of the merger agreement is attached as Appendix A to the Proxy Statement.
 
   
     Greyhound stockholders of record at the close of business on February 8,
1999 are entitled to notice of, and to vote at, the special meeting and any
adjournment or postponement of the special meeting.
    
 
     Greyhound stockholders who do not vote in favor of adopting the merger
agreement and who otherwise comply with the requirements of Delaware law will be
entitled to appraisal rights. A summary of the applicable Delaware law
provision, including the requirements a Greyhound stockholder must follow in
order to exercise his or her appraisal rights, is contained in the accompanying
Proxy Statement. A copy of the applicable Delaware law provision is attached as
Appendix C to the Proxy Statement.
 
     Please complete, date, sign and promptly mail the enclosed proxy card in
the enclosed postage-paid envelope to make sure that your vote will be counted
and your shares are represented at the special meeting. Record holders of
Greyhound common stock and preferred stock may also vote their shares by using a
toll free telephone number as described in the voting materials. If you attend
the special meeting, you may vote your shares in person even if you have
previously sent in your proxy card or voted by telephone. You may revoke your
proxy in the manner described in the Proxy Statement at any time before it is
voted at the special meeting. Signed proxies with no instructions indicated will
be voted "FOR" both the adoption of the merger agreement and the other proposal.
 
                                    By Order of the Board of Directors,

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
The following questions and answers are intended to address briefly some
commonly asked questions regarding the merger. These questions and answers may
not address all questions that may be important to you as a Greyhound
stockholder. Please refer to the more detailed information contained elsewhere
in this Proxy Statement, the Appendices and the documents referred to or
incorporated by reference.
 
Q:   IF THE MERGER IS COMPLETED, WHAT WILL I RECEIVE FOR MY GREYHOUND COMMON
     STOCK?
 
A:   You will receive $6.50 in cash for each share of Greyhound common stock you
     own.
 
Q:   HOW WILL THE MERGER AFFECT MY GREYHOUND PREFERRED STOCK?
 
A:   You may continue to own your Greyhound preferred stock after the merger.
     However, your Greyhound preferred stock will no longer be convertible into
     Greyhound common stock after the merger. Instead, each share of Greyhound
     preferred stock will be convertible into the right to receive $33.33 in
     cash. You may convert your Greyhound preferred stock into Greyhound common
     stock at any time before the merger is completed.
 
Q:   WHO IS ENTITLED TO VOTE AT THE SPECIAL MEETING?
 
   
A:   Holders of record of Greyhound common stock and Greyhound preferred stock
     as of the close of business on February 8, 1999 are entitled to vote at the
     special meeting. Each Greyhound stockholder has one vote for each share of
     Greyhound common stock and Greyhound preferred stock they own. Holders of
     Greyhound common stock and Greyhound preferred stock vote together as one
     class.
    
 
Q:   WHAT VOTE IS REQUIRED FOR THE GREYHOUND STOCKHOLDERS TO APPROVE THE MERGER?
 
A:   In order for the merger to be approved, holders of a majority of the
     outstanding Greyhound common stock and the Greyhound preferred stock,
     voting together as one class, must vote "FOR" the merger.
 
Q:   WHAT DO I NEED TO DO NOW?
 
A:   After carefully reading and considering the information contained in this
     Proxy Statement, please vote your shares as soon as possible. You may vote
     your shares either by returning the enclosed proxy or by calling the toll
     free telephone number on your proxy card. Your voting materials include
     detailed information on how to vote.
 
Q:   IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
     SHARES FOR ME?
 
A:   No. Your broker can vote your shares only if you provide instructions to
     him or her on how to vote. You should instruct your broker on how to vote
     your shares, using the instructions provided by your broker.
 
Q:   CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY PROXY CARD OR VOTED BY
     TELEPHONE?
 
A:   Yes. You can change your vote at any time before your proxy is voted at the
     special meeting. You may revoke your proxy by notifying the Secretary of
     Greyhound in writing or by submitting a new proxy dated after the date of
     the proxy being revoked. You may also revoke your proxy by calling toll
     free 1-800-840-1208, even if you did not previously vote by telephone. In
     addition, your proxy will be revoked by attending the special meeting and
     voting in person. However, simply attending the special meeting will not
     revoke your proxy. If you have instructed a broker
 
                                        1
<PAGE>   6
 
     to vote your shares, you must follow the instructions received from your
     broker to change your vote.
 
Q:   DO I NEED TO ATTEND THE GREYHOUND SPECIAL MEETING IN PERSON?
 
A:   No. It is not necessary for you to attend the special meeting in order to
     vote your shares, although you are welcome to attend.
 
Q:   WILL I HAVE APPRAISAL RIGHTS AS A RESULT OF THE MERGER?
 
A:   Yes. Both holders of Greyhound common stock and holders of Greyhound
     preferred stock have appraisal rights. If you wish to exercise your
     appraisal rights you must follow the requirements of Delaware law. A
     summary describing the requirements you must follow in order to exercise
     your appraisal rights is described in "The Merger -- Appraisal Rights" in
     this Proxy Statement.
 
Q:   WHEN WILL HOLDERS OF GREYHOUND COMMON STOCK RECEIVE THE MERGER
     CONSIDERATION?
 
   
A:   The merger is expected to be completed promptly following the special
     meeting of the Greyhound stockholders. However, it is possible that delays
     could require that the merger be completed at a later time. Following the
     merger, you will receive instructions on how to receive your cash payment
     in exchange for your shares of Greyhound common stock. You must return your
     Greyhound stock certificate as described in the instructions. You will
     receive your cash payment as soon as practicable after Laidlaw receives
     your Greyhound stock certificate.
    
 
Q:   SHOULD I SEND IN MY GREYHOUND STOCK CERTIFICATES NOW?
 
A:   No. After the merger is completed, Laidlaw will send the Greyhound
     stockholders written instructions for exchanging their Greyhound stock
     certificates.
 
Q:   WILL I OWE TAXES AS A RESULT OF THE MERGER?
 
A:   The merger will be a taxable transaction for all holders of Greyhound
     common stock and for holders of Greyhound preferred stock who exercise
     their appraisal rights. As a result, the cash you receive in the merger in
     exchange for your shares of Greyhound common stock and any cash you may
     receive from exercising your appraisal rights will be subject to federal
     income tax and also may be taxed under applicable state, local and other
     tax laws. In general, you will recognize gain (or loss) equal to the
     difference between (a) the amount of cash you receive and (b) the tax basis
     of your shares of Greyhound common stock exchanged in the merger or the tax
     basis of your shares subject to appraisal rights. Refer to the section
     entitled "The Merger -- Certain Federal Income Tax Income Consequences" in
     this Proxy Statement for a more detailed explanation of the tax
     consequences of the merger, including tax consequences to holders of
     Greyhound preferred stock. You should consult your tax advisor regarding
     the specific tax consequences of the merger applicable to you.

THE PARTIES
 
GREYHOUND. Greyhound is the only nationwide provider of scheduled intercity bus
transportation services in the United States. Greyhound also provides package
express delivery services, charter bus service and, in many terminals, food
service.
 
The principal executive offices of Greyhound are located at 15110 N. Dallas
Parkway, Suite 600, Dallas, Texas 75248, and its telephone number is (972)
789-7000.
 
LAIDLAW. Laidlaw is the largest school bus operator in North America and the
largest ambulance operator in the United States. In October 1997, Laidlaw
acquired Greyhound Canada Transportation Corp., which operates intercity buses
in Canada under the "Greyhound" trademark, but is not related to Greyhound.
Laidlaw also provides services to hospital emergency departments in the United
States.
 
The principal executive offices of Laidlaw are located at 3221 North Service
Road, Burlington, Ontario, Canada L7R 3Y8, and its telephone number is (905)
336-1800.
 
THE MERGER
 
   
GENERAL. In the merger, a subsidiary of Laidlaw will be merged into Greyhound,
with Greyhound being the surviving corporation. Upon completion of the merger,
Greyhound will become a subsidiary of Laidlaw. Subject to satisfaction or waiver
of certain conditions contained in the merger agreement, Greyhound and Laidlaw
presently intend to file a Certificate of Merger with the Secretary of State of
the State of Delaware promptly following the special meeting if a majority of
the holders of the outstanding shares of Greyhound common and preferred stock
vote to adopt the merger agreement. The merger will be effective upon the filing
of the Certificate of Merger or such later time as is specified in the
Certificate of Merger (the "Effective Time"). The total purchase price Laidlaw
will pay in the merger for the shares of Greyhound common stock it does not
presently own, including outstanding stock options, is approximately $398
million. The Greyhound preferred stock is presently convertible into Greyhound
common stock. Following the merger, the Greyhound preferred stock will be
convertible into the right to receive $33.33 in cash per share, or $80 million
in the aggregate. In addition, Laidlaw will indirectly assume Greyhound's debt
as a result of the merger. At September 30, 1998, Greyhound had outstanding debt
of $263 million.
    
 
CONDITIONS TO THE MERGER. The obligations of Greyhound and Laidlaw to complete
the merger are subject to a number of conditions, including:
 
   -   adoption of the merger agreement by the holders of a majority of the
       outstanding shares of Greyhound common stock and Greyhound preferred
       stock voting together as one class;
 
   -   no court order prohibiting the merger and no law in effect making the
       merger illegal; and
 
   -   the Bear Stearns fairness opinion not having been modified or withdrawn.
 
See "The Merger -- The Merger Agreement -- Conditions to the Merger."
                                        3
<PAGE>   8
 
TERMINATION; BREAK-UP FEE. The merger agreement may be terminated at any time
prior to the Effective Time in any one of the following circumstances:
 
   -   by the mutual written consent of the Greyhound Board and the Laidlaw
       Board;
 
   -   by Greyhound or Laidlaw, if any court or other governmental agency issues
       a nonappealable final order or ruling or has taken any action to
       permanently prevent the merger (but neither party may terminate if their
       failure to perform their obligations contained in the merger agreement
       materially contributed to the issuance of the order or ruling, or the
       taking of such action);
 
   -   by Greyhound or Laidlaw, if Greyhound enters into an agreement with
       respect to a superior proposal (which means an acquisition proposal that
       the Greyhound Board believes, after consultation with Bear Stearns, is
       more favorable, from a financial point of view, to Greyhound and its
       stockholders than the merger);
 
   -   by Laidlaw, if the Greyhound Board withdraws, modifies or changes its
       approval or recommendation of the merger agreement or the merger in a
       manner adverse to Laidlaw;
 
   -   by Greyhound or Laidlaw, if any representation or warranty made by the
       other party in the merger agreement was untrue on the date the
       representation or warranty was made, or the other party fails to comply
       in any material respect with any of the agreements made by such other
       party in the merger agreement (subject to a materiality standard and time
       to correct the error as described in the merger agreement), but neither
       party may terminate if they are in material breach of their
       representations, warranties or agreements contained in the merger
       agreement;
 
   -   by Greyhound or Laidlaw, if the special meeting was held and the merger
       agreement was not adopted by Greyhound stockholders; or
 
   -   by Greyhound or Laidlaw, if the merger is not completed by March 31,
       1999, but neither party may terminate if their failure to perform their
       obligations contained in the merger agreement is the reason the merger
       was not completed by that date.
 
Greyhound will be required to pay Laidlaw a termination fee of $20 million (the
"Termination Fee") if the merger agreement is terminated by Laidlaw because
either Greyhound entered into an agreement relating to a superior proposal or
the Greyhound Board withdraws or modifies its recommendation or approval of the
merger or merger agreement and a superior proposal has been made and is pending.
See "The Merger -- The Merger Agreement -- Termination; Break-Up Fee."
 
TREATMENT OF GREYHOUND STOCK OPTIONS. Greyhound will offer holders of an
outstanding option to purchase shares of Greyhound common stock the right to
cancel each of their Greyhound stock options in exchange for an amount in cash
equal to $6.50 less the exercise price of the Greyhound stock option. In the
event that any Greyhound stock option is not canceled prior to the Effective
Time, such Greyhound stock option will remain outstanding under the terms of the
applicable Greyhound stock option plan. This offer, however, will not be made
with respect to the Greyhound stock options issuable under a plan ("Union Option
Plan") for one of the unions that represents certain Greyhound employees.
Instead, the effects of the merger on the Greyhound stock options granted under
the Union Option Plan will be governed by the terms of the Union Option Plan.
See "The Merger -- The Merger Agreement -- Treatment of Greyhound Stock
Options."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER. Some of Greyhound's management and
directors may have interests in the merger that are different from or in
addition to the interests of stockholders of Greyhound generally. For example,
each of Greyhound's executive officers has an employment or
                                        4
<PAGE>   9
 
severance agreement with Greyhound that entitles that officer to receive a
severance payment if his employment with Greyhound is terminated under certain
circumstances within two years following a "change in control" of Greyhound. In
addition, under the terms of Greyhound's stock incentive plans, all unvested
options and unvested grants of restricted stock will vest upon a "change in
control" of Greyhound. The completion of the merger will be a "change in
control" for the purposes of both these agreements and the stock incentive
plans.
 
At Laidlaw's request, Mr. Lentzsch, Greyhound's President and Chief Executive
Officer, and Mr. Haugsland, Greyhound's Executive Vice President and Chief
Operating Officer, will enter into new employment agreements with Greyhound that
will become effective upon completion of the merger. As a result, it is not
presently anticipated that these individuals' employment will be terminated
following the merger. However, the estimated severance payments that would be
payable to Greyhound's three most highly compensated officers if their
employment is terminated immediately following the merger are as follows:

RECOMMENDATION OF THE GREYHOUND BOARD
 
The Board of Directors of Greyhound has, by the unanimous vote of all directors
present, approved the merger agreement. THE GREYHOUND BOARD BELIEVES THAT THE
MERGER IS IN THE BEST INTERESTS OF GREYHOUND AND ITS STOCKHOLDERS AND RECOMMENDS
THAT THE GREYHOUND STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE MERGER AGREEMENT.
 
OPINION OF GREYHOUND'S FINANCIAL ADVISOR
 
Bear, Stearns & Co. Inc. was retained by the Greyhound Board to act as its
exclusive financial advisor to evaluate the merger and the fairness, from a
financial point of view, of the consideration to be received by the Greyhound
stockholders. Bear Stearns has delivered its opinion dated as of October 16,
1998 to the effect that, as of the date of such opinion and based upon and
subject to the assumptions, limitations and qualifications contained in its
opinion, the consideration to be received by the Greyhound stockholders in the
merger is fair, from a financial point of view, to the Greyhound
                                        5

common and preferred stockholders. A copy of the Bear Stearns opinion is
attached as Appendix B to this Proxy Statement. Greyhound stockholders are urged
to read the Bear Stearns opinion carefully and in its entirety to understand the
procedures followed, assumptions made, matters considered and limitations on the
opinion. See "The Merger -- Opinion of Greyhound's Financial Advisor."
 
CERTAIN LITIGATION
 
Greyhound has obtained copies of two complaints filed in Delaware Chancery Court
purportedly filed by certain individual Greyhound stockholders on behalf of
themselves and all other Greyhound stockholders alleging, among other things,
that Greyhound's directors breached their fiduciary duties in approving the
merger. These suits name Greyhound, each of its directors and Laidlaw as
defendants. Greyhound has not filed answers to these suits, as the time period
for doing so was extended. However, Greyhound intends to defend these suits
vigorously. See "The Merger -- Certain Litigation."

                              THE SPECIAL MEETING
 
GENERAL
 
   
The special meeting will be held on Tuesday, March 16, 1999, starting at 9:00
a.m., local time, at the Hilton Dallas Parkway Hotel, 4801 LBJ Freeway, in
Dallas, Texas. The purpose of the special meeting is for the Greyhound
stockholders to consider and vote upon a proposal to adopt the merger agreement.
    
 
THE GREYHOUND BOARD BELIEVES THAT THE MERGER IS IN THE BEST INTERESTS OF
GREYHOUND AND ITS STOCKHOLDERS AND RECOMMENDS THAT GREYHOUND STOCKHOLDERS VOTE
"FOR" THE ADOPTION OF THE MERGER AGREEMENT.
 
Greyhound has been advised that a representative of Arthur Andersen LLP,
Greyhound's independent auditors, will be present at the special meeting. This
representative will have an opportunity to make a statement if he or she wishes
and will be available to respond to appropriate questions presented at the
special meeting.
 
VOTING AT THE SPECIAL MEETING
 
   
The holders of record of Greyhound common stock and Greyhound preferred stock as
of the close of business on the record date are entitled to receive notice of,
and to vote at, the special meeting. On the record date, there were 60,146,675
shares of Greyhound common stock outstanding held by 11,230 stockholders of
record. On the record date, there were 2,400,000 shares of Greyhound preferred
stock outstanding held by six stockholders of record.
    
 
The holders of a majority of the outstanding shares of Greyhound common stock
and Greyhound preferred stock on the record date, represented in person or by
proxy, will constitute a quorum for purposes of the special meeting. A quorum is
necessary to hold the special meeting. Any shares of Greyhound common stock held
in treasury by Greyhound or by any of its subsidiaries are not considered to be
outstanding for purposes of determining a quorum. Once a share is represented at
the special meeting, it will be counted for the purpose of determining a quorum
at the special meeting and any adjournment of the special meeting unless the
holder is present solely to object to the special meeting. However, if a new
record date is set for the adjourned meeting, then a new quorum will have to be
established.
 
REQUIRED VOTE
 
Each outstanding share of Greyhound common stock and Greyhound preferred stock
on the record date is entitled to one vote at the special meeting. The merger is
conditioned upon, among other things, the adoption of the merger agreement by
the affirmative vote of the holders of a majority of the outstanding shares of
Greyhound common stock and Greyhound preferred stock voting together as one
class. You must vote your shares either in person, by proxy or by telephone in
order for your shares to be included in the vote. Record holders of Greyhound
common stock and Greyhound preferred stock may vote by telephone by following
the instructions shown on the proxy card. Not voting has the same effect as
voting against adoption of the merger agreement. Your broker or nominee does not
have the right to vote your shares of Greyhound common and preferred stock. You
must instruct your broker on how to vote in order for your shares to be voted.
It is important that you instruct your broker or nominee on how to vote your
shares of Greyhound common and preferred stock in order for your shares to be
represented at the special meeting.

Laidlaw has agreed to vote all of their shares of Greyhound common stock "For"
the adoption of the merger agreement. As of the record date, Laidlaw and its
subsidiaries owned 1,389,700 shares of Greyhound common stock or approximately
2.3% of all outstanding shares of Greyhound common stock on such date. As of the
record date, the directors and executive officers of Greyhound and their
affiliates owned, in the aggregate, 318,234 shares of Greyhound common stock, or
less than 1.0% of the outstanding shares of Greyhound common stock on such date.
All such directors and executive officers have informed Greyhound that they
intend to vote all of their shares of Greyhound common stock "For" the adoption
of the merger agreement.
 
PROXIES; REVOCATION
 
If you vote your shares of Greyhound common and preferred stock by signing a
proxy, your shares will be voted at the special meeting as you indicate on your
proxy card. If no instructions are indicated on your signed proxy card, your
shares of Greyhound common and preferred stock will be voted "For" the adoption
of the merger agreement.
 
You may revoke your proxy at any time before the proxy is voted at the special
meeting. A proxy may be revoked prior to the vote at the special meeting by
submitting a written revocation to the Secretary of Greyhound or by submitting a
new proxy dated after the date of the proxy that is being revoked. You may also
revoke your proxy by calling toll free 1-800-840-1208, even if you did not
previously vote by telephone. In addition, a proxy may also be revoked by voting
in person at the special meeting. However, simply attending the special meeting
will not, in itself, revoke a proxy.
 
Greyhound and Laidlaw will share the costs associated with preparing this Proxy
Statement. Greyhound will pay the costs of soliciting proxies for the special
meeting. Further, certain officers and employees of Greyhound may also solicit
proxies by telephone or in person. Officers and other employees of Greyhound
will not be paid for soliciting proxies. Greyhound will also request persons and
entities holding shares in their names or in the names of their nominees that
are beneficially owned by others to send proxy materials to and obtain proxies
from such beneficial owners and will reimburse such holders for their reasonable
expenses in performing such services. Greyhound has retained Kissel-Blake Inc.
to assist it in the solicitation of proxies using the means referred to above,
at an anticipated cost of $11,500, plus reimbursement of out-of-pocket expenses.
 
ADJOURNMENTS
 
Although it is not expected, the special meeting may be adjourned for the
purpose of soliciting additional proxies or for other reasons. Any adjournment
may be made by approval of the holders of a majority of the outstanding shares
of Greyhound common and preferred stock present in person or represented by
proxy at the special meeting (whether or not a quorum exists) without notice
other than by an announcement made at the special meeting. Greyhound does not
currently intend to seek a postponement or adjournment of the special meeting.
Any postponement or adjournment of the special meeting for the purpose of
soliciting additional proxies will allow the Greyhound stockholders who have
already sent in their proxies to revoke them at any time prior to their use.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
Laidlaw owns and operates a number of passenger transportation businesses.
Laidlaw is the largest school bus operator in North America. Laidlaw also
operates municipal, intercity and charter buses, as well as ambulances. In
October 1997, Laidlaw acquired Greyhound Canada Transportation Corp., which is
unrelated to Greyhound. The Greyhound Canada acquisition significantly expanded
Laidlaw's intercity bus operations.
 
Laidlaw has pursued a strategy of acquiring companies to expand its
transportation businesses, and considered Greyhound as a potential acquisition
candidate for some time. Laidlaw's interest in acquiring Greyhound increased
following its acquisition of Greyhound Canada. At meetings of the Laidlaw Board
held in January and April 1998, James R. Bullock, Laidlaw's President and Chief
Executive Officer, reviewed with the Laidlaw Board several transportation
companies, including Greyhound, as potential acquisition candidates. Prior to
initiating discussions with Greyhound, Laidlaw purchased 1.4 million shares of
Greyhound common stock in open-market transactions.
 
Greyhound's business is capital intensive and Greyhound has pursued a
growth-oriented strategy, including acquisitions, since its reorganization in
1994. From time to time, representatives of Greyhound have considered various
acquisitions, joint ventures, recapitalizations, business combination
transactions and other strategic alternatives intended to further its growth
strategy and to maximize stockholder value, and had discussions with
representatives of other companies relating to the foregoing. While Greyhound
was not pursuing a business combination transaction or sale of Greyhound at the
time Laidlaw initiated discussions with Greyhound, the Greyhound Board was
willing to consider such a transaction if it appeared to be in the best
interests of Greyhound and its stockholders.
 
On May 21, 1998, Mr. Bullock and Craig R. Lentzsch, Greyhound's President and
Chief Executive Officer, met at Mr. Bullock's request for the stated purpose of
exchanging views on the intercity bus transportation industry. At that meeting,
Mr. Bullock also indicated to Mr. Lentzsch that Laidlaw desired to explore a
possible business combination transaction with Greyhound. However, Mr. Bullock
did not indicate a proposed price or form of consideration, although he did
indicate that he contemplated a transaction structure in which Laidlaw common
shares would be used for all or a substantial part of the consideration. Mr.
Lentzsch informed Mr. Bullock that, while Greyhound was not for sale, he would
discuss Mr. Bullock's indication of interest with Thomas G. Plaskett, the
Chairman of the Board of Greyhound.
 
From time to time over the next several weeks, Messrs. Lentzsch and Plaskett
discussed the possibility of entering into discussions with Laidlaw regarding a
possible business combination transaction. They also had informal discussions
with the members of the Executive Committee of the Greyhound Board in this
regard. A committee of the Greyhound Board was then formed to consider any
proposal that Laidlaw might make. The members of the Greyhound Board Committee
were Mr. Plaskett, A.A. Meitz and Stephen M. Peck, each of whom is a
non-employee director of Greyhound and was believed to have experience and
expertise that could be useful in considering a possible business combination
transaction. After discussions among the Greyhound Board Committee members,
Greyhound retained Bear Stearns to serve as Greyhound's financial advisor and
Jones, Day, Reavis & Pogue to act as Greyhound's legal advisor in connection
with the matter.
 
                                       11
<PAGE>   16
 
Messrs. Lentzsch and Bullock spoke by telephone on a number of occasions
following their initial meeting in May 1998. On June 26, 1998, Mr. Bullock and
other senior management personnel of Laidlaw met with the members of the
Greyhound Board Committee, Mr. Lentzsch and other senior management personnel of
Greyhound to review their respective businesses and strategic plans. The two
companies' representatives also discussed, in general terms, the manner by which
the two companies could be combined, although no specific terms of such a
transaction were proposed at this meeting. However, Mr. Bullock continued to
suggest consideration of a transaction using Laidlaw common shares for all or
part of the consideration.
 
The Greyhound Board met on June 29, 1998. At this meeting, the members of the
Greyhound Board Committee and Mr. Lentzsch reviewed the discussions to date with
Laidlaw. It was the consensus of the Greyhound Board that a possible business
combination transaction with Laidlaw should continue to be explored.
 
The parties entered into a confidentiality agreement and, over the course of the
next six weeks, representatives of the parties exchanged financial and operating
information relating to their respective businesses. During that period, the
members of the Greyhound Board Committee were kept apprised of the status of the
discussions between Greyhound and Laidlaw. In light of, among other factors, the
increasing volatility of the securities markets, it was the consensus of the
Greyhound Board Committee that it would be preferable for the consideration in
any such transaction to be cash, or if Laidlaw common shares were used, that the
transaction be structured so that Greyhound stockholders would be protected
against declines in stock market prices to the extent reasonably possible.
 
The Laidlaw Board met on July 9, 1998. At this meeting, Mr. Bullock reviewed
with the Laidlaw Board the status of discussions with Greyhound. The Laidlaw
Board agreed that Mr. Bullock should continue his discussions with Greyhound's
representatives.
 
On August 13, 1998, Messrs. Plaskett and Lentzsch met with Mr. Bullock.
Following a general discussion of recent events, including a U.S. tax court
decision adverse to Laidlaw that had received substantial coverage in the
financial media, Mr. Bullock outlined a possible business combination
transaction involving the conversion of each share of Greyhound common stock
into two-thirds of a Laidlaw common share. Laidlaw common shares were trading at
$9 5/16 per share at that time (based on the closing sale price on August 12,
1998), making the implied value of Mr. Bullock's indication $6.21 per share of
Greyhound common stock. The closing sales price of the Greyhound common stock on
August 12, 1998 was $4 13/16. Messrs. Plaskett and Lentzsch indicated that they
did not believe the Greyhound Board would be willing to continue to pursue
discussions of a possible business combination transaction on the terms
indicated by Mr. Bullock in light of, among other factors, the implicit value of
the transaction to Greyhound's stockholders as well as the recent volatility in
the market price for Laidlaw common shares, in part attributable to the adverse
U.S. tax court decision and in the securities markets generally. Mr. Bullock
indicated that he would consider the matter further.
 
On September 8, 1998, Messrs. Bullock, Lentzsch and Plaskett and other
representatives of Laidlaw and Greyhound, including representatives of Bear
Stearns, Jones Day and Laidlaw's financial advisor, Merrill Lynch, met to
determine whether there was a substantial basis to continue discussions of a
possible business combination transaction involving Laidlaw and Greyhound. In
that meeting, Mr. Bullock initially indicated a stock-for-stock transaction with
a value of $6.00 to $7.00 per share of Greyhound common stock. After further
negotiations, he modified his indication to provide for a transaction valued at
$7.00 per share of Greyhound common stock in cash, with Laidlaw having the
option to pay up to $4.00 of the purchase price with Laidlaw common shares. In
response to
 
                                       12
<PAGE>   17
 
Greyhound's continued desire for a transaction structured to preserve the dollar
value of the transaction to the extent reasonably practicable, after discussing
various alternatives, Laidlaw's representatives proposed, in principle, the
following structure:
 
   -   Laidlaw would be required to announce whether it intended to pay any
       portion of the merger consideration with Laidlaw common shares at least
       five trading days prior to the meeting of Greyhound stockholders to be
       called to vote on the transaction;
 
   -   the Laidlaw common shares would be valued based on the weighted average
       sale price of the Laidlaw common shares for the five trading days
       immediately prior to the fifth trading day before such stockholder
       meeting;
 
   -   the transaction would close promptly after the vote of the Greyhound
       stockholders; and
 
   -   the transaction would be taxable to Greyhound stockholders for U.S.
       federal income tax purposes regardless of whether Laidlaw elected to pay
       a portion of the merger consideration in Laidlaw common shares.
 
With regard to the taxable nature of the proposed transaction, Laidlaw's
representatives indicated that a tax-free structure would require that Laidlaw
substantially reduce the stated value of the merger consideration because of the
adverse effect that a tax-free transaction would have on the post-merger value
of the transaction to Laidlaw. The structure also was responsive to concerns
expressed by Messrs. Plaskett and Lentzsch at the August 13, 1998 meeting with
Mr. Bullock that they believed that the Greyhound Board would prefer a structure
in which the risk that the transaction consideration would materially decline in
value between the time of announcement and completion of a transaction was
minimized. Messrs. Plaskett and Lentzsch indicated at the September 8th meeting
that they would be willing to review Laidlaw's proposal with the Greyhound Board
Committee and the parties agreed to continue with their respective due diligence
investigations and consideration of a possible business combination transaction.
 
Over the succeeding four weeks, representatives of Greyhound and Laidlaw met, in
person and by telephone, to exchange additional information, to carry out due
diligence reviews and to negotiate the terms of the merger agreement.
 
   
At its regularly scheduled meeting on September 15, 1998, the Greyhound Board
reviewed the status of the discussions between Greyhound and Laidlaw. At this
meeting, representatives of Bear Stearns made a presentation regarding the
financial analysis they had performed to date with respect to a possible
business combination transaction with Laidlaw. Bear Stearns' presentation also
included a review of the proposed transaction with Laidlaw, a review of
Greyhound's financial results over the past several years as well as the recent
market performance of the Greyhound common stock and a discussion of its views
of Greyhound's potential opportunities and challenges. At the conclusion of this
meeting, the Greyhound Board authorized continued discussions with Laidlaw.
    
 
On September 30, 1998, the Laidlaw Board met to review the status of the
discussions between Laidlaw and Greyhound. Mr. Bullock reviewed the results of
ongoing due diligence investigations and the financial aspects of a possible
transaction. The Laidlaw Board authorized Mr. Bullock to continue the
discussions with Greyhound.
 
On October 9, 1998, Messrs. Bullock, Plaskett and Lentzsch met at Mr. Bullock's
request. Mr. Bullock informed Messrs. Plaskett and Lentzsch that, due to the
continuing volatility in the equity and debt markets, as well as recent changes
in the outlook for the economy generally, he no
 
                                       13
<PAGE>   18
 
longer believed that the Laidlaw Board would support a proposal to acquire
Greyhound valued at $7.00 per share of Greyhound common stock. At that time,
Greyhound common stock was trading at $3 5/8. Mr. Bullock indicated that he
believed that the Laidlaw Board probably would support a proposal valued at
$6.00 per share of Greyhound common stock, so long as it was structured along
the lines indicated by Mr. Bullock in the September 8, 1998 meeting. Messrs.
Lentzsch and Plaskett indicated to Mr. Bullock that they did not believe the
Greyhound Board would approve a transaction at that price level, but that some
reduction from the $7.00 price might be possible. Messrs. Bullock, Plaskett and
Lentzsch agreed to further consider the matter.
 
On October 11, 1998, Messrs. Bullock and Lentzsch again discussed a possible
business combination transaction. In that discussion, Mr. Lentzsch indicated
that, based on discussions with the members of the Greyhound Board Committee and
Mr. Plaskett's discussions with other Greyhound Board members, he believed that
the Greyhound Board Committee and the Greyhound Board might support a
transaction valued at $6.50 per share of Greyhound common stock, but that he
personally would not recommend a transaction at a lower price. Mr. Bullock
indicated that he was not certain what the Laidlaw Board would decide on this
issue, but indicated that he would discuss the transaction with the Laidlaw
Board and, if authorized, would make a definitive proposal following a Laidlaw
Board meeting scheduled for October 14, 1998. Mr. Lentzsch inferred from the
conversation that Mr. Bullock personally would support a transaction at $6.50
per share of Greyhound common stock, but it was unclear whether the Laidlaw
Board would authorize a transaction at that valuation.
 
The Greyhound Board Committee and Mr. Lentzsch considered the alternatives that
might be available to Greyhound in light of the indication by Mr. Bullock that
Laidlaw would only be willing to proceed at a price lower than its original
indication of $7.00 per share. The principal alternatives considered were the
continued pursuit of Greyhound's business plan as an independent company and the
initiation of discussions with other parties. It was the consensus of the
Greyhound Board Committee and Greyhound's senior management that the continued
pursuit of a possible business combination transaction would be desirable in
light of Greyhound's substantial capital requirements and the recent
deterioration of the capital markets. Given the nature of Greyhound's business,
it was believed that the universe of potential parties that would be willing to
consider a potential transaction with Greyhound was relatively limited and that
Laidlaw was likely to be the best potential buyer for Greyhound in light of,
among other factors, its ownership of Greyhound Canada and its school bus
business, which created possible synergies in a merger with Greyhound. The
Greyhound Board Committee and senior management of Greyhound also believed that
it was unlikely that another strategic partner would be willing to pursue a
business combination transaction on terms superior to those believed to be
available from Laidlaw. In this regard, in early October 1998, representatives
of another transportation company had indicated a preliminary interest in
pursuing discussions regarding a possible business combination transaction with
Greyhound, but had not received any confidential information relating to
Greyhound. In addition, representatives of the other party had indicated a price
range substantially below the $7.00 per share of Greyhound common stock price
indicated by Laidlaw and below the $6.50 price which, based on discussions on
October 8th and 11th, Greyhound believed would ultimately be proposed by
Laidlaw. The preliminary discussion with this party did not address whether the
consideration would be paid in cash, stock or some combination of cash and
stock. Based on the fact that this other transportation company does not have
operations in North America and management's assessment of its financial
condition, it was the consensus of the Greyhound Board Committee and Greyhound's
senior management that the other party did not have sufficient synergies and
sources of low-cost capital to make reasonably possible a proposal with a value
greater than that indicated by Laidlaw and that, if Greyhound were to pursue
substantive discussions with that party, there was a substantial risk that the
discussions with Laidlaw would be
 
                                       14
<PAGE>   19
 
adversely affected. Accordingly, it was the consensus of the Greyhound Board
Committee and Greyhound's senior management not to pursue discussions with the
other party until the negotiations with Laidlaw were concluded.
 
In order to prepare for the possibility of receiving a definitive proposal from
Laidlaw, on October 13, 1998, the Greyhound Board held a special meeting in
which certain members of Greyhound's senior management as well as
representatives of Bear Stearns and Jones Day participated. The discussions at
this meeting were wide-ranging and extensive, and included the following:
 
   -   a review by Greyhound's senior management of the recent discussions with
       representatives of Laidlaw;
 
   -   a presentation by representatives of Bear Stearns regarding the equity
       and debt markets generally; and
 
   -   presentations by Greyhound's senior management of the effects of the
       capital markets and economic conditions generally on Greyhound's
       financial condition and future prospects, as well as its potential impact
       on Greyhound's ability to meet its current business plan.
 
In that regard, representatives of Bear Stearns commented on the recent
volatility in the capital markets generally and specifically the debt markets
for non-investment grade borrowers such as Greyhound. Representatives of
Greyhound's management advised the Greyhound Board of its views on the impact of
these market conditions on Greyhound's ongoing bus financing program. It was the
consensus of the Greyhound Board that if these market conditions were to exist
for any significant period of time, there was a risk that Greyhound would be
unable to meet its business plan.
 
Representatives of Bear Stearns also reviewed, at the request of the Greyhound
Board, Bear Stearns' analysis of a possible transaction involving Laidlaw as
more fully described below under "The Merger -- Opinion of Greyhound's Financial
Advisor." The Greyhound Board also considered other strategic alternatives
available to Greyhound, including continuing to pursue its strategic plan as an
independent company, as well as pursuing merger discussions with other potential
parties. Following further discussion, the Greyhound Board agreed to meet again
on October 15, 1998, Mr. Bullock having indicated to Mr. Lentzsch that the
Laidlaw Board was expected to consider the matter by October 14, 1998.
 
On October 14, 1998, the Laidlaw Board authorized Mr. Bullock to propose a
business combination transaction with Greyhound in which each share of Greyhound
common stock would be converted into $6.50 in cash, with Laidlaw having an
option to pay up to $4.00 in Laidlaw common shares on the basis previously
proposed by Laidlaw, and with the Greyhound preferred stock receiving the same
consideration as the Greyhound common stock multiplied by the then-current
conversion ratio for the Greyhound preferred stock. Following the Laidlaw Board
meeting, Mr. Bullock informed Mr. Lentzsch of the proposal. Mr. Lentzsch
informed Mr. Bullock that Laidlaw's proposal would be considered by the
Greyhound Board the next day.
 
The Greyhound Board met on October 15, 1998, to review Laidlaw's proposal with
the assistance of Greyhound's senior management and Greyhound's financial and
legal advisors, Bear Stearns and Jones Day. All members of the Greyhound Board
were present at the meeting, except for one director who, due to prior
commitments, was able to participate by telephone in only a portion of the
meeting.
 
                                       15
<PAGE>   20
 
At the October 15, 1998 meeting, the Greyhound Board received presentations and
discussed various matters, including:
 
   -   a review by Greyhound's senior management of the course of the
       discussions with Laidlaw and other matters pertaining to the proposed
       merger, including the due diligence reviews that had been undertaken and
       management's perspective on Laidlaw's ability to finance the merger;
 
   -   a review by Greyhound's senior management of its views as to Greyhound's
       business, financial condition, results of operations and prospects;
 
   -   a presentation by Bear Stearns regarding its financial analysis of the
       proposed merger, including an analysis of Laidlaw;
 
   -   a presentation by representatives of Jones Day regarding the duties of
       directors in this context; and
 
   -   a presentation by representatives of Jones Day regarding the terms of the
       draft merger agreement and related documentation, including the so-called
       no-shop and break-up fee provisions and the provisions in the draft
       merger agreement and other aspects of the transaction in which members of
       the Greyhound Board or management could be said to have interests that
       were different from or in addition to the interests of Greyhound
       stockholders generally (see "The Merger -- Interests of Certain Persons
       in the Merger").
 
The Greyhound Board also received a presentation from representatives of Jones
Day regarding such firm's review of a U.S. tax case decided in June 1998 adverse
to Laidlaw. The review was primarily based on Jones Day's examination of the
court filings in the litigation, Laidlaw's public filings relating to the matter
and discussions with Laidlaw's representatives. Jones Day's presentation
involved a review of the factual circumstances giving rise to the litigation,
the positions of the parties in the litigation, the adverse U.S. tax court
decision and the current status of the litigation.
 
   
The Greyhound Board then discussed the proposed transaction in detail. At the
conclusion of the discussions, a representative of Bear Stearns orally informed
the Greyhound Board, which oral advice was subsequently confirmed in writing,
that, in Bear Stearns' opinion, the consideration to be received by the
Greyhound stockholders in the merger was fair to the Greyhound common and
preferred stockholders from a financial point of view. At that point, the
representatives from Bear Stearns and Jones Day were excused from the meeting
and the Greyhound Board further discussed the possible transaction. Thereafter,
the Greyhound Board, by unanimous vote of all directors present (one non-
employee director being absent from the portion of the meeting at which the vote
was taken), approved the merger agreement and the transactions contemplated
thereby. The Greyhound Board is comprised of nine directors, only one of which
is employed at Greyhound.
    
 
The Laidlaw Board approved the merger agreement on October 16, 1998. Thereafter,
the merger agreement was finalized and executed and the transaction was publicly
announced prior to the commencement of trading on October 19, 1998.
 
Following the public announcement of the merger, lawsuits were filed by certain
persons that purport to be Greyhound stockholders on behalf of themselves and
certain other Greyhound stockholders. In these lawsuits, the plaintiffs allege,
among other things, that certain provisions of the merger agreement violate
Delaware law and that the Greyhound Board breached its fiduciary duties in
approving the merger. See "The Merger -- Certain Litigation."
 
                                       16
<PAGE>   21
 
Following the announcement of the proposed merger, certain holders of Greyhound
preferred stock contacted representatives of both Greyhound and Laidlaw
requesting that the merger agreement be modified to permit the Greyhound
preferred stock to remain outstanding in the merger. While both Laidlaw and
Greyhound believe that the treatment of the Greyhound preferred stock originally
proposed was in accordance with the terms thereof and applicable law, the
parties were willing to modify the merger agreement to permit the Greyhound
preferred stock to remain outstanding following the merger. Inasmuch as such
modification did not adversely affect the common stockholders of either
Greyhound or Laidlaw, the modification was approved and publicly announced on
November 5, 1998. In connection with the approval of the modification of the
merger agreement, Bear Stearns reissued its opinion as of October 16, 1998
relating to the fairness, from a financial point of view, of the merger
consideration to the Greyhound stockholders.
 
On January 26, 1999, Laidlaw irrevocably waived its right to pay a portion of
the merger consideration with Laidlaw common shares. As a result, the merger
consideration will be paid entirely in cash.
 
GREYHOUND'S REASONS FOR THE MERGER
 
The Greyhound Board has, by the unanimous vote of all directors present (one
director being absent from the Greyhound Board meeting at which the merger
agreement was approved), determined that the merger is fair to and in the best
interests of Greyhound and its stockholders. Accordingly, the Greyhound Board
approved the merger agreement and recommended that the Greyhound stockholders
adopt the merger agreement. Prior to approving the merger, the Greyhound Board
considered the following factors that it considered material:
 
   -   Greyhound's business plan as an independent company in the context of its
       assessment of Greyhound's business, operations, financial position,
       personnel and prospects;
 
   -   the possible difficulties in continuing to increase Greyhound's revenues
       and earnings if Greyhound were to remain independent as a result of a
       number of factors, including Greyhound's ability to continue funding its
       capital expenditure requirements and acquisitions on favorable terms;
 
   -   presentations by, and discussions with, senior management of Greyhound
       and representatives of Bear Stearns and Jones Day regarding the terms of
       the merger agreement and the results of the due diligence review of
       Laidlaw conducted by Greyhound's management, Bear Stearns and Jones Day;
 
   -   the advice of Bear Stearns described below under "Opinion of Greyhound's
       Financial Advisor" and its oral opinion (which was subsequently confirmed
       in writing) to the effect that the merger consideration is fair to the
       Greyhound common and preferred stockholders from a financial point of
       view;
 
   -   that the merger consideration to be received by holders of Greyhound
       common stock was (a) 92.6% higher than the lowest closing sale price of
       the Greyhound common stock over the prior 12-month period, (b) 1.0%
       higher than the highest closing sale price of the Greyhound common stock
       over the prior 12-month period, and (c) 49% higher than the closing sale
       price of the Greyhound common stock at the close of business on October
       14, 1998;
 
   -   that the merger would be a taxable transaction to the holders of
       Greyhound common stock and that at least $2.50 of the per share merger
       consideration would be paid in cash which could be used to satisfy all or
       some portion of any tax liability resulting from the merger;
 
                                       17
<PAGE>   22
 
   -   that the merger agreement does not prohibit Greyhound from participating
       in discussions or negotiations with, or furnishing information (pursuant
       to a confidentiality agreement) to, any person or entity if the Greyhound
       Board concludes (after consultation with its financial advisor) that such
       person or entity has made or is reasonably likely to make a bona fide
       proposal for a transaction which it believes may be more favorable than
       the merger from a financial point of view (a "Superior Proposal");
 
   -   the ability of the Greyhound Board to terminate the merger agreement upon
       payment of the Termination Fee if the Greyhound Board decides to approve
       a Superior Proposal;
 
   -   the financial condition of Laidlaw and the ability of Laidlaw to complete
       the merger in a timely manner; and
 
   -   the regulatory approvals required in connection with the merger,
       including that receipt of STB approval was not a condition to the
       obligations of Laidlaw or Greyhound to complete the merger.
 
In addition, the Greyhound Board also considered that under the terms of the
merger agreement as originally negotiated Laidlaw would have had the option
(which it subsequently waived) to pay a significant part of the merger
consideration with Laidlaw common shares. Accordingly, the Greyhound Board
considered the following additional factors, assuming Laidlaw paid part of the
merger consideration with Laidlaw common shares:
 
   -   the business, operations, financial position, personnel and prospects of
       Laidlaw;
 
   -   the merger would enable the Greyhound stockholders to own shares in
       Laidlaw, which is a company with more diverse businesses than those of
       Greyhound. At the same time, ownership of Laidlaw common shares would
       afford Greyhound stockholders the opportunity to continue to participate
       in the long-term growth and appreciation of the bus transportation
       business;
 
   -   the trading volume of Laidlaw common shares, which would provide
       Greyhound stockholders with greater liquidity in their investment than
       they have had with their shares of Greyhound common stock;
 
   -   the fit between the respective businesses of Greyhound and Laidlaw;
 
   -   the potential for cost savings from combining Greyhound with Laidlaw,
       which the Greyhound Board believes would have a favorable impact on the
       long-term value for the holders of Laidlaw common shares;
 
   -   certain risks associated with Laidlaw and the merger, including an
       adverse U.S. tax court decision against Laidlaw and its possible effect
       on Laidlaw's future earnings; and
 
   -   the historical trading prices of Laidlaw common shares and in that regard
       the Greyhound Board noted that the Laidlaw common shares were then
       trading substantially below its 52-week high.
 
In light of the Greyhound Board's knowledge of the business and operations of
Greyhound and its business judgment, the Greyhound Board considered and
evaluated each of the factors listed above during the course of its
deliberations prior to approving the merger agreement. Each of the factors
listed above was believed by the Greyhound Board to support the decision to
adopt the merger agreement, except for the factor relating to the taxable nature
of the merger, which was specifically negotiated in connection with the
transaction. In view of the wide variety of factors considered in connection
with its evaluation of the merger, the Greyhound Board found it impracticable
to, and did
 
                                       18
<PAGE>   23
 
not, quantify or otherwise attempt to assign relative weights to the specific
factors considered in making its determinations.
 
After considering all of the foregoing factors, the Greyhound Board concluded
that the merger is fair to and in the best interests of Greyhound and its
stockholders. The Greyhound Board believes that the factors listed above, when
considered together, support the fairness of the merger to Greyhound and its
stockholders. THE GREYHOUND BOARD BELIEVES THAT SUCH FACTORS SUPPORT ITS
RECOMMENDATION THAT THE GREYHOUND STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT.
 
OPINION OF GREYHOUND'S FINANCIAL ADVISOR
 
Greyhound retained Bear Stearns to act as its exclusive financial advisor and to
render an opinion to the Greyhound Board as to the fairness of the merger
consideration, from a financial point of view, to the Greyhound stockholders.
Bear Stearns is an internationally recognized investment banking firm that has
previously provided investment banking services to Greyhound and Laidlaw and is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and other purposes.
 
At the Greyhound Board meeting held on October 15, 1998, Bear Stearns presented
its analysis of the merger. Bear Stearns subsequently delivered its written
opinion to the Greyhound Board dated as of October 16, 1998 to the effect that,
as of such date, the merger consideration was fair, from a financial point of
view, to the Greyhound stockholders.
 
The full text of the Bear Stearns opinion is attached as Appendix B to this
Proxy Statement. The Bear Stearns opinion is intended for the benefit and use of
the Greyhound Board in its evaluation of the merger. Greyhound stockholders are
urged to, and should, read the Bear Stearns opinion carefully in its entirety in
conjunction with this Proxy Statement for the assumptions made, matters
considered and limits of the review by Bear Stearns. The Bear Stearns opinion
addresses only the fairness of the merger consideration, from a financial point
of view, to the Greyhound stockholders and does not constitute a recommendation
to the Greyhound Board or to any Greyhound stockholder as to how to vote in
connection with the merger. The Bear Stearns opinion does not address
Greyhound's underlying business decision to pursue the merger. The summary of
the Bear Stearns opinion set forth in this Proxy Statement is qualified in its
entirety by reference to the full text of such opinion.
 
In rendering its fairness opinion, Bear Stearns met with certain members of the
senior management of each of Greyhound and Laidlaw to discuss the respective
operations, historical financial statements and future prospects of each
company. In addition, Bear Stearns reviewed the following:
 
   -   the merger agreement;
 
   -   Greyhound's Annual Reports to Shareholders and Annual Reports on Form
       10-K for the fiscal years ended December 31, 1995 through 1997, and its
       Quarterly Reports on Form 10-Q for the quarters ended March 31, 1998 and
       June 30, 1998;
 
   -   certain operating and financial information relating to Greyhound's
       business and prospects, including internal financial projections,
       provided to Bear Stearns and reviewed for Bear Stearns by Greyhound's
       management;
 
   
   -   Laidlaw's Annual Reports to Shareholders and Annual Reports on Form 10-K
       for the fiscal years ended August 31, 1995 through 1997, its Quarterly
       Reports on Form 10-Q for the quarters ended November 30, 1997, February
       28, 1998 and May 31, 1998, and a draft of its consolidated financial
       statements for the fiscal year ended August 31, 1998;
    
 
                                       19
<PAGE>   24
 
   -   certain operating and financial information relating to Laidlaw's
       business and prospects, including internal financial projections,
       provided to Bear Stearns and reviewed for Bear Stearns by Laidlaw's
       management;
 
   -   the historical prices and trading volumes of the Greyhound common stock
       and Laidlaw common shares;
 
   -   publicly available financial data, stock market performance data and
       valuation parameters of companies which Bear Stearns deemed generally
       comparable to Greyhound and Laidlaw; and
 
   -   the financial terms of recent acquisitions of companies which Bear
       Stearns deemed generally comparable to the merger.
 
Bear Stearns also conducted such other studies, analyses, inquiries and
investigations that it deemed appropriate in connection with rendering its
fairness opinion.
 
   
In the course of its review, Bear Stearns relied upon and assumed, without
assuming any responsibility for independent verification, the accuracy and
completeness of all of the financial and other information (including estimates
and projections) provided to, discussed with, or reviewed by or for Bear Stearns
by Greyhound and Laidlaw or publicly available for purposes of its opinion,
including the adequacy of Laidlaw's reserves relating to loss contingencies.
Bear Stearns further relied upon the assurances of senior management of both
Greyhound and Laidlaw that they were unaware of any facts that would make the
information, estimates and projections provided to, discussed with, or reviewed
by or for Bear Stearns incomplete, inaccurate or misleading. With respect to
Greyhound's and Laidlaw's internal financial projections and estimates of
potential synergies that could be achieved upon consummation of the merger, Bear
Stearns assumed that they had been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the senior managements of
Greyhound and Laidlaw as to the expected future performance of Greyhound and
Laidlaw. Bear Stearns expressed no view as to such information, or the
assumptions on which they were based. For purposes of rendering its opinion,
Bear Stearns further assumed, based on statements made by Laidlaw in its public
reports filed with the SEC, that the U.S. tax court decision adverse to Laidlaw
would not have a material adverse effect on Laidlaw's financial condition,
results of operations, business or prospects. In arriving at its opinion, Bear
Stearns did not perform or obtain any independent appraisal of the assets or
liabilities of Greyhound or Laidlaw, nor had Bear Stearns been furnished with
any such appraisals. For purposes of rendering its opinion, Bear Stearns
assumed, in all respects material to its analysis, that the merger will be
consummated substantially in accordance with the terms set forth in the merger
agreement, that the representations and warranties of each party contained in
the merger agreement were true and correct, that each party will perform all of
the covenants and agreements required to be performed by it under the merger
agreement and all conditions to the consummation of the merger will be satisfied
without waiver by either Greyhound or Laidlaw. Bear Stearns did not express any
opinion as to the price or range of prices at which the Laidlaw common shares
may trade following the merger. The Bear Stearns opinion is necessarily based on
economic, market and other conditions, and the information made available to it,
as of October 16, 1998, except with respect to the merger agreement which was
amended and restated as of November 5, 1998.
    
 
The following is a brief summary of all the material financial analyses used by
Bear Stearns in connection with rendering its opinion to the Greyhound Board.
 
STOCK TRADING HISTORY. Bear Stearns reviewed the historical market prices and
trading volumes of Greyhound common stock and Laidlaw common shares during the
12-month period prior to the delivery of the Bear Stearns opinion. Bear Stearns
observed that the merger consideration to be

COMPARABLE COMPANY ANALYSIS. Bear Stearns reviewed and compared the financial
and stock market performance of Greyhound to the financial and stock market
performance of certain publicly-traded companies in the surface transportation
industry that Bear Stearns believed were generally comparable to Greyhound (the
"Comparable Companies"). The Comparable Companies included Laidlaw, Coach USA,
Inc. ("Coach USA") and Ryder System, Inc. ("Ryder"). Bear Stearns also reviewed
and compared similar data for a composite of six regional airline companies (the
"Regional Airlines") including ASA Holdings, Inc., Comair Holdings, Inc., Mesa
Air Group, Inc., Mesaba Holdings, Inc., Midwest Express Holdings, Inc. and
SkyWest, Inc. While no group is directly comparable to Greyhound, regional
airlines were included given that (a) they are a transportation-related industry
with certain operating characteristics consistent with those of Greyhound, (b)
in certain markets they compete with Greyhound and (c) their financial
performance is impacted by many of the same macroeconomic factors that impact
Greyhound. For each of the Comparable Companies and the Regional Airlines, Bear
Stearns reviewed certain publicly available financial data, including revenue,
earnings before interest, taxes, depreciation and amortization ("EBITDA"),
earnings before interest and taxes ("EBIT"), net income and earnings per share
("EPS") over various time periods as well as certain valuation statistics,
financial ratios, published earnings estimates for 1998 and 1999 and stock
market information.
 
For each of the Comparable Companies and the Regional Airlines composite, Bear
Stearns calculated the ratio of their equity value plus debt less cash and cash
equivalents ("Enterprise Value") as of October 13, 1998 to their respective
EBITDA during the most recent last 12-month period ("LTM") and the ratios of
their stock prices as of October 13, 1998 to their respective LTM earnings per
share and projected 1998 and 1999 earnings per share. As shown in the table
below, Bear Stearns observed that the merger consideration produced multiples
that exceeded the trading multiples of the Comparable Companies and the Regional
Airlines composite.

Bear Stearns chose the Comparable Companies and Regional Airlines because they
have general business, operating and financial characteristics similar to those
of Greyhound. However, Bear Stearns noted that no company used in the foregoing
analysis is identical to Greyhound. Accordingly, Bear Stearns did not rely
solely on the mathematical results of the analysis, but also made qualitative
 
                                       21
<PAGE>   26
 
judgments concerning differences in financial and operating characteristics of
Greyhound, the Comparable Companies and the Regional Airlines that could affect
the values of each.
 
PRESENT VALUE OF HYPOTHETICAL STOCK PRICE ANALYSIS. Bear Stearns performed an
analysis of what a share of Greyhound common stock could be worth in the future
if Greyhound continued to operate as a stand-alone entity. Bear Stearns used
Greyhound's projected earnings per share for 2000 through 2002 based on two
financial scenarios provided by management. Bear Stearns applied a range of
assumed future price/earnings multiples based on the trading ranges of the
Comparable Companies and Regional Airlines. The resulting hypothetical future
stock prices were then discounted back to the present using a discount rate of
14.5%, reflecting Bear Stearns' estimate of Greyhound's cost of equity. As shown
in the following table, the analysis yielded a range of values of $1.98 to $6.53
per share, and Bear Stearns observed that the merger consideration was at the
upper end of this range.

COMPARABLE ACQUISITION ANALYSIS. Bear Stearns reviewed certain
publicly-available financial information related to seven merger and acquisition
transactions completed in the passenger services industry that it deemed
generally comparable to the merger (the "Comparable Transactions"). Of these
seven transactions, financial data was publicly available for the following five
transactions (acquired company/acquiring company): Greyhound Canada
Transportation Corp./Laidlaw, Valley Transit Co./ Greyhound, Carolina Coach
Company/Greyhound, 6 transportation companies/Coach USA (August, 1996) and 6
transportation companies/Coach USA (founding transactions). For each of these
five transactions, Bear Stearns reviewed certain publicly available financial
information for the acquired companies including revenue, EBITDA, EBIT and
certain valuation statistics. As shown in the table below, Bear Stearns compared
such results and observed that the merger consideration produced multiples that
compare favorably to the results of the Comparable Transactions analysis.

</TABLE>
 
Bear Stearns noted that no transaction used in the foregoing analysis is
identical to the merger. Accordingly, an analysis of the results of the
foregoing is not mathematical; rather, it involves a number of considerations
and judgments concerning differences in financial and operating characteristics
of the companies and the Comparable Transactions and other factors that could
affect the value of the companies or transactions to which Greyhound or the
merger are being compared.
 
DISCOUNTED CASH FLOW ANALYSIS. Bear Stearns performed a discounted cash flow
analysis of Greyhound based upon financial projections prepared by Greyhound's
management for the fiscal years ending December 31, 1999 through December 31,
2002. Using a range of discount rates reflecting Bear Stearns' estimate of
Greyhound's weighted average after-tax cost of capital, Bear Stearns calculated
the present value of the projected Free Cash Flows (as defined below) for each
of the fiscal years ending December 31, 1999 through 2002, the present value of
the terminal value (the "Terminal Value") of Greyhound at December 31, 2002 and
the present value of expected tax savings from Greyhound's available tax net
operating loss carryforwards. As used in Bear Stearns'
 
                                       22
<PAGE>   27
 
analysis, "Free Cash Flow" means, for each fiscal year, earnings before interest
and taxes, less estimated taxes, plus depreciation and amortization, less
capital expenditures and less incremental working capital requirements. The
Terminal Value was computed by applying a range of assumed growth rates of Free
Cash Flow into perpetuity. The following table shows the assumed range of
perpetual growth rates and discount rates, as well as the range of terminal
multiples of 2002 EBITDA and multiples of 2002 net income that are implied by
the range of equity values determined in this analysis.

                                                              ---------------------
<S>                                                           <C>      <C>   <C>
Discount Rate Assumption....................................   11.5%    --    10.5%
Perpetual Growth Rate of Free Cash Flow Assumption..........    1.5%    --     2.5%
Implied Terminal 2002 EBITDA Multiple.......................    4.2x    --     5.9x
Implied Terminal 2002 Net Income Multiple...................   11.7x    --    20.4x
Implied Equity Value per Share..............................  $ 2.57    --   $ 6.83
</TABLE>
 
To calculate the aggregate net present value of the equity of Greyhound, Bear
Stearns subtracted total debt minus cash and cash equivalents of Greyhound from
the sum of the present value of the projected Free Cash Flows, the present value
of the Terminal Value and the present value of the expected tax savings from
Greyhound's available tax net operating loss carryforwards. Based on this
analysis and the assumptions set forth above, Bear Stearns calculated the
implied equity value per fully diluted share of Greyhound Common Stock to be
between $2.57 and $6.83 per share. Bear Stearns observed that the merger
consideration was at the upper end of this value range.
 
The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary described above, without considering
the analysis as a whole, could create an incomplete view of the processes
underlying the Bear Stearns opinion. In arriving at its opinion, Bear Stearns
considered the results of all the analyses it performed. Such analyses were
prepared solely for purposes of providing its opinion as to the fairness of the
merger consideration, from a financial point of view, to the Greyhound
stockholders and do not purport to be appraisals or necessarily indicate the
prices at which businesses or securities actually may be sold. Analyses based
upon forecasts of future results are not necessarily indicative of actual future
results, which may be significantly more or less favorable than those results
suggested by such analyses. As described above, the Bear Stearns opinion and
Bear Stearns' presentation to the Greyhound Board were two of many factors taken
into consideration by the Greyhound Board in making its determination to approve
the merger. The foregoing summary does not purport to be a complete description
of the analyses performed by Bear Stearns in rendering its opinion.
 
In the ordinary course of business, Bear Stearns may actively trade the equity
securities of Greyhound and Laidlaw for its own account and for the accounts of
its customers and, accordingly, may, at any time, hold a long or short position
in such securities.
 
Under the terms of a letter dated June 18, 1998, Greyhound paid Bear Stearns a
retainer fee of $100,000 and paid Bear Stearns an additional fee of $100,000 at
the time negotiations relating to the merger began. Greyhound has also paid Bear
Stearns a fee of $1.0 million for rendering its opinion relating to the merger.
Greyhound has also agreed to pay Bear Stearns a fee equal to 0.55% of the
aggregate value of the merger, which includes the assumption of debt, capital
leases and certain other liabilities. This fee is payable upon completion of the
merger, against which all fees described above would be credited. Greyhound also
agreed to reimburse Bear Stearns for its out-of-pocket expenses, including the
reasonable fees and disbursements of counsel and to indemnify Bear Stearns and
certain
 
                                       23
<PAGE>   28
 
related persons against certain liabilities in connection with the engagement of
Bear Stearns, including certain liabilities under the federal and state
securities laws.
 
LAIDLAW'S REASONS FOR THE MERGER
 
The Laidlaw Board has unanimously determined that the merger is fair to and in
the best interests of the holders of Laidlaw common shares. Accordingly, the
Laidlaw Board approved the merger agreement. The Laidlaw Board considered a
number of factors prior to approving the merger, including:
 
   -   the merger is consistent with Laidlaw's long-term objective of delivering
       shareholder value by growth through acquisitions and internal growth;
 
   -   the merger will provide entry into significant new geographic markets for
       Laidlaw's existing scheduled intercity bus transportation business,
       enhancing the value of the Canadian Greyhound business previously
       acquired by Laidlaw and Laidlaw's strategic objective of expanding this
       business;
 
   -   the merger will add significant management expertise in Laidlaw's
       scheduled intercity bus transportation business; and
 
   -   the combined company will have the potential to realize cost savings in
       administration, insurance and in purchasing supplies and equipment, as
       compared to the two companies continuing to operate separately.
 
   
CERTAIN PROJECTED FINANCIAL INFORMATION
    
 
   
In the course of the discussions described in "The Merger  -- Background of the
Merger," Greyhound provided Laidlaw with certain financial information. This
information included financial projections prepared by Greyhound's management
for 1998 through 2002 that was not publicly available. These projections were
prepared in mid-1998 in the ordinary course of business for internal budgeting
and planning purposes only and not with a view to public disclosure. Further,
the projections were prepared assuming that Greyhound would remain an
independent public company and did not take into account any of the potential
effects of the merger, or the time and attention of management and other
employees of Greyhound devoted to the negotiations and consummation of the
merger during 1998 and 1999.

(a)  The lower end of the range for 1998 does not assume the recognition of the
     tax benefit related to prior years net operating losses which Greyhound
     subsequently recognized in the third quarter of 1998. The upper end of the
     range shown for 1998 reflects the recognition of the tax benefit.
    
 
   
A number of significant assumptions were used in preparing the projections.
Greyhound believes the following were the material assumptions:
    
 
   
   -   a sustained growth rate for the bus passenger business of between 3.9%
       and 8.6% annually;
    
 
   
   -   net income reported on a fully taxed basis beginning in 1999;
    
 
   
   -   the conversion of the Greyhound preferred stock into 12.3 million shares
       of Greyhound common stock effective May 2000;
    
 
   
   -   the completion of unidentified acquisitions representing $25 million in
       annualized revenue per acquisition for the projections at the upper end
       of the range in each of the years 1999 through 2001;
    
 
   
   -   the availability of lease, debt and equity financing on terms acceptable
       to Greyhound on an ongoing basis in order to fund capital expenditures
       and acquisitions;
    
 
   
   -   no significant change in the existing competitive or economic conditions;
       and
    
 
   
   -   the ability to recruit and retain drivers and other key personnel
       necessary to carry out its planned growth.
    
 
   
Greyhound understands that Laidlaw took into consideration historical
fluctuations in Greyhound's results of operations in evaluating Greyhound's
projections. Laidlaw reviewed these projections and developed its own internal
projections based on the information about Greyhound available to Laidlaw,
including information which was publicly available.
    
 
   
Greyhound's projections have been included in this Proxy Statement only because
this information was provided to Laidlaw, which reviewed these projections when
performing its analysis of the merger. As a matter of course, neither Greyhound
nor Laidlaw makes public projections or forecasts of its anticipated financial
position or results of operations. Accordingly, neither Greyhound nor Laidlaw
anticipates that it will, and each of them disclaims any obligation to, provide
updated projections, cause this information to be included in documents required
to be filed with the SEC or otherwise make this information public (irrespective
of whether Greyhound's projections, in light of
    
 
                                       25
<PAGE>   30
 
   
events or developments that have occurred after the date Greyhound's projections
were provided to Laidlaw or that may occur after the date of this Proxy
Statement, cease to have a reasonable basis).
    
 
   
Greyhound's projections were not prepared with a view to public disclosure or
compliance with published guidelines of the SEC or the guidelines established by
the American Institute of Certified Public Accountants. Further, while presented
with numerical specificity, Greyhound's projections were based upon a variety of
assumptions relating to general economic conditions and the business of
Greyhound which may not be realized and are subject to significant uncertainties
and contingencies, many of which are beyond the control of Greyhound and
Laidlaw. There can be no assurance that Greyhound's projections will be realized
and actual results may vary materially from those shown. The inclusion of these
projections in this Proxy Statement should not be regarded as an indication that
Greyhound considers these projections to be an accurate prediction of future
events. Furthermore, external factors, in addition to the proposed merger,
continually change and as a result, if Greyhound's management were to prepare
updated projections, those projections could vary substantially from those
provided to Laidlaw.
    
 
   
Greyhound's projections should be evaluated in conjunction with Greyhound's
historical financial statements and other information contained in reports filed
with the SEC from time to time by Greyhound.
    
 
THE MERGER AGREEMENT
 
The following is a summary of the material terms of the merger agreement. This
summary is not a complete description of the terms and conditions of the merger
agreement and is qualified in its entirety by reference to the full text of the
merger agreement, a copy of which is attached as Appendix A to this Proxy
Statement. Terms used in this section of this Proxy Statement with initial
capital letters that are not otherwise defined in the Proxy Statement have the
meaning given to those terms in the merger agreement.
 
THE MERGER. At the Effective Time, a subsidiary of Laidlaw, Laidlaw Acquisition
Transit Corp., will be merged into Greyhound in accordance with the applicable
provisions of the DGCL. Following the merger, Laidlaw will own all of the
outstanding shares of Greyhound common stock.
 
Upon the satisfaction or waiver of all the conditions contained in the merger
agreement (other than those to be satisfied at the closing), Greyhound and
Laidlaw Acquisition will file the Certificate of Merger with the Secretary of
State of the State of Delaware as required by the DGCL. The merger will become
effective immediately upon filing of the Certificate of Merger or at such later
time as is specified in the Certificate of Merger.
 
MERGER CONSIDERATION. At the Effective Time, as a result of the merger and
without any action on the part of any stockholder:
 
   -   each share of Greyhound common stock outstanding immediately prior to the
       Effective Time (other than those canceled by the terms of the merger
       agreement and any dissenting shares) will be converted into the right to
       receive $6.50 in cash;
 
   -   each share of Greyhound common stock outstanding immediately prior to the
       Effective Time and owned by Greyhound or any Greyhound subsidiary or by
       Laidlaw, Laidlaw Acquisition or any other Laidlaw subsidiary will
       automatically be canceled and retired without the payment of any
       consideration;
 
                                       26
<PAGE>   31
 
   -   each share of Greyhound preferred stock outstanding immediately prior to
       the Effective Time (other than any dissenting shares) will remain issued
       and outstanding and have the identical powers, preferences, rights,
       qualifications, limitations and restrictions as the Greyhound preferred
       stock had prior to the merger. Under the terms of the Greyhound preferred
       stock, following the merger, the Greyhound preferred stock will be
       convertible into the same merger consideration paid to the holders of
       Greyhound common stock multiplied by the number of shares of Greyhound
       common stock issuable upon conversion of one share of Greyhound preferred
       stock. Each share of Greyhound preferred stock is currently convertible
       into approximately 5.128 shares of Greyhound common stock, resulting in a
       post-merger conversion price per share of Greyhound preferred stock of
       $33.33; and
 
   -   each share of common stock of Laidlaw Acquisition outstanding immediately
       prior to the Effective Time will be converted into and exchanged for one
       share of Greyhound common stock.
 
UNDER THE TERMS OF THE MERGER AGREEMENT, LAIDLAW HAD THE OPTION TO PAY UP TO
$4.00 OF THE MERGER CONSIDERATION WITH LAIDLAW COMMON SHARES. HOWEVER, ON
JANUARY 26, 1999 LAIDLAW IRREVOCABLY WAIVED ITS RIGHT TO PAY A PORTION OF THE
MERGER CONSIDERATION WITH LAIDLAW COMMON SHARES. AS A RESULT, THE MERGER
CONSIDERATION WILL BE PAID ENTIRELY IN CASH.
 
Laidlaw will designate a bank or trust company (the "Paying Agent") to act as
the agent for the merger. The Paying Agent will receive the merger consideration
from Laidlaw and distribute the cash merger consideration to each holder of
Greyhound common stock after they have delivered their Greyhound common stock
certificates along with a signed letter of transmittal to the Paying Agent.
 
DISSENTING SHARES. In the merger, the holders of Greyhound common stock and
Greyhound preferred stock have appraisal rights under Section 262 of the DGCL
("Section 262"). If a Greyhound stockholder exercises his or her appraisal
rights and complies with the requirements of Section 262 (a "Dissenting
Stockholder"), the shares of Greyhound common stock owned by the Dissenting
Stockholder will not be converted into the right to receive the merger
consideration at the Effective Time. Instead, such Dissenting Stockholder will
receive the appraised value of his or her shares of Greyhound common stock. The
shares of Greyhound preferred stock owned by a Dissenting Stockholder will not
remain outstanding following the merger. Instead, such Dissenting Stockholder
will receive the appraised value of his or her Greyhound preferred stock. The
shares of Greyhound common stock or Greyhound preferred stock owned by a
Dissenting Stockholder are referred to as "Dissenting Shares." If, after the
Effective Time, the Dissenting Stockholder fails to comply with the requirements
of Section 262, the Dissenting Shares of such Dissenting Stockholder will be
treated as shares of Greyhound common stock or Greyhound preferred stock, as the
case may be, and will be converted into the right to receive the merger
consideration in the case of the Greyhound common stock or will remain
outstanding in the case of the Greyhound preferred stock. At the Effective Time,
a Dissenting Stockholder will not have any rights (including voting rights and
rights to dividends or distributions) with respect to his or her Dissenting
Shares other than the rights provided by Section 262. For a summary of the
requirements that a Greyhound stockholder must follow in order to exercise his
or her appraisal rights, see "The Merger -- Appraisal Rights."
 
TREATMENT OF GREYHOUND STOCK OPTIONS. Greyhound will offer holders of a
Greyhound stock option, whether or not the Greyhound stock option is
exercisable, the right to cancel his or her Greyhound stock option in exchange
for an amount in cash equal to $6.50 less the exercise price of the Greyhound
stock option. In the event that any Greyhound stock option is not canceled prior
to the Effective Time, that Greyhound stock option will remain outstanding under
the terms of the applicable Greyhound stock option plan. This offer, however,
will not be made with respect to
                                       27
<PAGE>   32
 
Greyhound stock options granted under the Union Option Plan. Instead, the
effects of the merger on the Greyhound stock options granted under the Union
Option Plan will be governed by the terms of the Union Option Plan.
 
   
REPRESENTATIONS AND WARRANTIES. The merger agreement contains various
representations and warranties of the parties including their respective
businesses and organizational documents, capital structure, authority to
execute, deliver and perform their respective obligations under the merger
agreement, required filings and consents, compliance with laws, filings with the
SEC, absence of certain changes and events, undisclosed liabilities, litigation,
employee benefit plans, labor matters, taxes, intellectual property and brokers.
    
 
The representations and warranties made by Greyhound and Laidlaw will not
survive beyond the Effective Time or the termination of the merger agreement.
However, if the merger is completed, Laidlaw's obligation to pay the merger
consideration will survive the Effective Time indefinitely and the agreements
relating to the treatment of the Greyhound stock options, indemnification and
insurance and the continuation of certain Greyhound benefits will survive for
the periods described in the merger agreement. If the merger agreement is
terminated, the obligation, if any, of Greyhound to pay the Termination Fee will
survive indefinitely.
 
CONSENTS, APPROVALS, AND FILINGS. Greyhound and Laidlaw are required to make all
governmental filings necessary to complete the merger, including with the STB.
Further, Greyhound and Laidlaw will obtain all consents, waivers, approvals,
authorizations and orders that are necessary to complete the merger. Greyhound
and Laidlaw have agreed to take, or cause to be taken, all appropriate actions,
and to do, or cause to be done, all things necessary or advisable under
applicable laws to complete the merger, including furnishing all information
required to be included in any application or filing necessary to complete the
merger. If final approval of the merger by the STB is not obtained prior to the
special meeting, Laidlaw has agreed to enter into a voting trust or similar
agreement in order to permit the completion of the merger before it receives
final approval from the STB.
 
NO SOLICITATION. Greyhound has agreed that it will not and will not permit any
of its subsidiaries or any of its or their officers, directors, employees,
agents or representatives, to solicit or initiate any inquiries or proposals
regarding or engage in negotiations or discussions concerning any merger, sale
of substantial assets, sale of capital stock (including any tender offer) or
other similar transaction involving Greyhound or its subsidiaries, other than
the transactions contemplated by the merger agreement (an "Acquisition
Proposal"). Greyhound has also agreed that it will not provide any nonpublic
information relating to Greyhound or its subsidiaries to any person who is
proposing an Acquisition Proposal, except as described below.
 
However, if the Greyhound Board concludes, after consultation with Bear Stearns
that a person has made or is likely to make a Superior Proposal, Greyhound may
provide information to and participate in discussions with the person making the
Superior Proposal. Greyhound has agreed to sign a confidentiality agreement with
any person making a Superior Proposal before Greyhound provides that person any
information or begins discussions with that person regarding the Superior
Proposal. The confidentiality agreement must be substantially similar to the
confidentiality agreement between Greyhound and Laidlaw.
 
Greyhound has agreed to notify Laidlaw immediately if it receives any written
Acquisition Proposal or if any pending Acquisition Proposal has been modified or
amended. Further, Greyhound has agreed to notify Laidlaw if it receives any
request for information relating to Greyhound or its subsidiaries or for access
to the properties, books or records of Greyhound or its subsidiaries by any
person who is considering making or who has made an Acquisition Proposal.

CONDITIONS TO THE MERGER. The merger agreement provides that the obligations of
Greyhound, Laidlaw and Laidlaw Acquisition to complete the merger are subject to
the satisfaction or written waiver on or prior to the closing date of the merger
(the "Closing Date") of the following conditions:
 
   -   the merger agreement will have been adopted by the holders of a majority
       of the outstanding shares of Greyhound common stock and Greyhound
       preferred stock, voting together as one class;
 
   -   no court order prohibiting the merger being in effect, and no action
       having been taken and no law being in effect which makes the merger
       illegal; and
 
   -   the opinion of Bear Stearns not having been modified in any material
       adverse manner or withdrawn.
 
The obligations of Laidlaw and Laidlaw Acquisition to complete the merger are
subject to satisfaction or written waiver on or prior to the Closing Date of the
following additional conditions:
 
   -   the representations and warranties made by Greyhound in the merger
       agreement were true and correct in all material respects on the date of
       the merger agreement and will be true on and as of the Closing Date
       (unless an earlier date is stated);
 
   -   Greyhound will have performed in all material respects all obligations it
       is required to perform under the merger agreement prior to the Closing
       Date; and
 
   -   Greyhound will have delivered to Laidlaw and Laidlaw Acquisition a
       certificate of Greyhound signed by an executive officer of Greyhound
       certifying to the conditions stated above.
 
The obligations of Greyhound to complete the merger are subject to satisfaction
or written waiver on or prior to the Closing Date of the following additional
conditions:
 
   -   the representations and warranties made by Laidlaw and Laidlaw
       Acquisition in the merger agreement were true and correct in all
       materials respects on the date of the merger agreement and will be true
       on and as of the Closing Date (unless an earlier date is stated);
 
   -   Laidlaw and Laidlaw Acquisition will have each performed in all material
       respects all obligations they are required to perform under the merger
       agreement prior to the Closing Date; and
 
   -   Laidlaw and Laidlaw Acquisition will have delivered to Greyhound a
       certificate of Laidlaw and Laidlaw Acquisition signed by an executive
       officer of each of them certifying to the conditions stated above.
 
TERMINATION; BREAK-UP FEE. The merger agreement may be terminated at any time
prior to the Effective Time in any one of the following circumstances:
 
   -   by the mutual written consent of the Greyhound Board and the Laidlaw
       Board;
 
   -   by Greyhound or Laidlaw, if any court or other governmental agency issues
       a nonappealable final order or ruling, or has taken any action to
       permanently prevent the merger (but neither Laidlaw nor Greyhound may
       terminate the merger agreement if they failed to perform their
       obligations under the merger agreement and their failure materially
       contributed to the issuance of the order or ruling, or the taking of such
       action);
 
   -   by Greyhound or Laidlaw, if Greyhound enters into an agreement with
       respect to a Superior Proposal;
 
   -   by Laidlaw, if the Greyhound Board withdraws, modifies or changes its
       approval or recommendation of the merger agreement or the merger in a
       manner adverse to Laidlaw;
 
                                       29
<PAGE>   34
 
   -   by Greyhound or Laidlaw (but only if the terminating party is not in
       material breach of any of the representations, warranties, covenants or
       agreements made by the terminating party in the merger agreement), if:
 
          -   the other party failed to comply in any material respect with any
              of the covenants and agreements made by such other party in the
              merger agreement; or
 
          -   any representation or warranty made by the other party in the
              merger agreement was untrue on the date the representation or
              warranty was made;
 
        in either case, if such event will have a material adverse effect on the
        other party. If, however, such event can be corrected, then the merger
        agreement may not be terminated under this provision if the breaching
        party uses its reasonable best efforts to correct the event or if the
        event is corrected;
 
   -   by Greyhound or Laidlaw, if the special meeting was held and the merger
       agreement was not adopted by a majority of the Greyhound stockholders; or
 
   -   by Greyhound or Laidlaw, if the merger is not completed by March 31,
       1999, but neither Greyhound nor Laidlaw may terminate if they failed to
       perform their obligations under the merger agreement and their failure is
       the reason the merger was not completed by that date.
 
If the merger agreement is terminated by Laidlaw because Greyhound enters into
an agreement for a Superior Proposal, Greyhound is required to pay Laidlaw the
Termination Fee. The Termination Fee is also payable to Laidlaw if the merger
agreement is terminated by Laidlaw because the Greyhound Board withdraws or
adversely modifies or changes its approval or recommendation of the merger
agreement or the merger and a Superior Proposal has been made and is pending.
The Termination Fee payable to Laidlaw is required to be paid within two
business days after the termination date. Greyhound will not be required to pay
any Termination Fee to Laidlaw if, immediately prior to such termination,
Greyhound could have terminated the merger agreement under certain
circumstances. Payment of the Termination Fee by Greyhound will be Laidlaw's
only remedy for the event giving rise to the payment of the Termination Fee.
 
SPECIAL MEETING. The merger agreement requires that Greyhound hold a meeting of
the Greyhound stockholders for the purpose of considering and voting on a
proposal to adopt the merger agreement. The merger agreement also provides that
the Greyhound Board recommend to the Greyhound stockholders that they vote "For"
the adoption of the merger agreement at the special meeting. However, the
Greyhound Board will not be required to make any recommendation to the Greyhound
stockholders if the Greyhound Board determines (after consultation with legal
counsel) that making the recommendation would be a breach of its fiduciary
duties to Greyhound and its stockholders.
 
INDEMNIFICATION AND INSURANCE. For a period of five years after the Effective
Time, Greyhound and Laidlaw have each agreed to indemnify each current and
former director, officer and employee of Greyhound or its subsidiaries (each, an
"Indemnified Party") against certain costs and expenses to the extent allowed
under Delaware law and the Greyhound Certificate or Greyhound Bylaws. The costs
and expenses may include attorneys' fees, judgments, fines, losses, claims,
damages and liabilities that relate to any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative (a)
relating to the merger or the merger agreement or (b) with respect to any acts
or omissions or alleged acts or omissions of the Indemnified Parties occurring
at or prior to the Effective Time.
 
For a period of five years after the Effective Time, Greyhound will be required
to maintain directors' and officers' liability insurance ("D&O Insurance") for
all Greyhound directors and officers who are presently covered under Greyhound's
current D&O Insurance policy. The terms of the D&O
 
                                       30
<PAGE>   35
 
Insurance to be maintained for the benefit of Greyhound's directors and officers
must be comparable to the terms of the D&O Insurance maintained by Laidlaw for
its directors and officers. However, if the terms of Greyhound's current D&O
Insurance is more favorable, then Greyhound will be required to maintain D&O
Insurance on terms similar to the current Greyhound D&O Insurance. Neither
Greyhound nor Laidlaw will be required to pay premiums on the D&O Insurance to
be maintained for the benefit of Greyhound's directors and officers in an amount
greater than of 300% of the annual premium currently paid by Greyhound for its
D&O Insurance.
 
Laidlaw will guarantee the obligations of Greyhound to indemnify the Indemnified
Parties and to provide D&O Insurance for the benefit of the Greyhound directors
and officers from and after the Effective Time. Laidlaw and Greyhound will also
require any person or entity that purchases the assets or business of Greyhound
following the merger to assume all of their obligations to indemnify, and to
provide D&O Insurance for, the Greyhound directors and officers described above.
 
EMPLOYEE BENEFIT MATTERS. Greyhound has agreed to continue, without amendment or
change (except changes which increase compensation or benefits or that may be
required by law), all Greyhound employee benefit plans and other policies and
arrangements which provide compensation or benefits to employees of Greyhound
and its subsidiaries for a period of at least one year following the merger.
Greyhound will not be required to maintain any Greyhound employee benefit plans
that conflict with any collective bargaining agreements to which Greyhound is a
party. Greyhound may replace any Greyhound employee benefit plan with any other
plan or arrangement that provides, at minimum, a substantially equivalent level
of compensation or benefits as currently provided. Greyhound will not be
required to maintain any Greyhound stock incentive plan if Laidlaw agrees to
replace that Greyhound stock incentive plan with another plan or arrangement
that the Greyhound Board determines in good faith provides comparable incentive
compensation opportunities.
 
Following the merger, Laidlaw has agreed to cause Greyhound to comply with all
employment, change-in-control, severance, termination, consulting and unfunded
retirement and benefit agreements to which Greyhound or any of its subsidiaries
is a party. Laidlaw has acknowledged that the merger constitutes a change in
control and any references to a change of control in these agreements will
include the merger.
 
FEES AND EXPENSES. All costs and expenses incurred in connection with the merger
and the merger agreement will be paid by the party incurring the expenses,
whether or not the merger is completed.
 
AMENDMENT; WAIVER. Greyhound and Laidlaw may amend the merger agreement at any
time before the Effective Time. Any amendment must be made in writing and signed
by Greyhound and Laidlaw. However, no amendment may be made after the Greyhound
stockholders have adopted the merger agreement which by law would require
further Greyhound stockholder approval. At any time prior to the Effective Time,
either party to the merger agreement may (a) extend the time for the performance
of any of the obligations or other acts of the other party, (b) waive any
inaccuracies in the representations and warranties made in the merger agreement
by the other party or (c) waive compliance with any of the agreements or
conditions contained in the merger agreement. Any extension or waiver must be
made in writing signed by the party or parties to be bound.
 
DELISTING OF GREYHOUND COMMON STOCK
 
If the merger is completed, the Greyhound common stock will cease to be listed
on the AMEX.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL. The following is a summary of the material federal income tax
consequences of the merger to Greyhound stockholders. This summary is based upon
the provisions of the Code, the applicable current and proposed Treasury
Regulations, judicial authority and administrative rulings and practice.
Legislative, judicial or administrative rules and interpretations are subject to
change, possibly on a retroactive basis, at any time and therefore could alter
or modify the following statements and conclusions. It is assumed that the
shares of Greyhound common stock or Greyhound preferred stock are held as
capital assets by a United States person (i.e., a citizen or resident of the
United States or a domestic corporation). This discussion does not address all
aspects of federal income taxation that may be relevant to a particular
Greyhound stockholder in light of such Greyhound stockholder's personal
investment circumstances, or those Greyhound stockholders subject to special
treatment under the federal income tax laws (for example, life insurance
companies, tax-exempt organizations, foreign corporations and nonresident alien
individuals), Greyhound stockholders who hold shares of Greyhound common stock
or Greyhound preferred stock as part of a conversion transaction under Section
1258 of the Code, or to Greyhound stockholders who acquired their shares of
Greyhound common stock through the exercise of employee stock options or other
compensation arrangements. In addition, the discussion does not address any
aspect of foreign, state, local or estate and gift taxation that may be
applicable to a Greyhound stockholder.
 
CONSEQUENCES OF THE MERGER TO GREYHOUND STOCKHOLDERS. The receipt of the merger
consideration in the merger (including any cash amounts received by Dissenting
Stockholders) will be a taxable transaction for federal income tax purposes (and
also may be a taxable transaction under applicable state, local and other income
tax laws). In general, for federal income tax purposes, a holder of Greyhound
common stock will recognize gain or loss equal to the difference between his or
her adjusted tax basis in the Greyhound common stock exchanged in the merger or
subject to appraisal rights, and the amount of cash received. The gain or loss
will be capital gain or loss, and will be short-term gain or loss subject to tax
at a maximum rate of 39.6% if, on the Effective Time, the shares of Greyhound
common stock so exchanged or subject to appraisal rights were held for one year
or less. If the shares were held for more than one year, the gain or loss would
be long term, subject to tax at a maximum rate of 20%.
 
The consummation of the merger will not be a taxable transaction for a holder of
Greyhound preferred stock unless that holder converts his or her shares of
Greyhound preferred stock into shares of Greyhound common stock prior to the
merger or receives cash as a result of exercising his or her appraisal rights.
Instead, gain or loss will generally be recognized for federal income tax
purposes (and also may be recognized under applicable state, local and other
income tax laws) on conversion of the Greyhound preferred stock into the merger
consideration. At the time of such conversion of the Greyhound preferred stock,
a holder of Greyhound preferred stock will recognize gain or loss equal to the
difference between his or her adjusted tax basis in the Greyhound preferred
stock, and the amount of cash received. The gain or loss will be capital gain or
loss, and will be short-term gain or loss subject to tax at a maximum rate of
39.6% if, on the conversion date, the shares of Greyhound preferred stock were
held for one year or less. If the shares were held for more than one year, the
gain or loss would be long term, subject to tax at a maximum rate of 20%. If
there is a dividend arrearage on the Greyhound preferred stock when the
conversion takes place, a portion of the merger consideration received may be
treated as a taxable dividend to the extent of such dividend arrearage.
 
Under the terms of the Greyhound preferred stock, after April 16, 1999 and
subject to certain conditions, Greyhound may exchange all, but not less than
all, of the then outstanding shares of Greyhound preferred stock into its 8 1/2%
Convertible Subordinated Debentures due 2009 (the "Greyhound Exchange
Debentures"). At the time of conversion of the Greyhound Exchange
 
                                       32
<PAGE>   37
 
Debentures, a holder of Greyhound Exchange Debentures will recognize gain or
loss in the same manner as described above on conversion of the Greyhound
preferred stock into the merger consideration. If there is accrued but unpaid
interest with respect to the Greyhound Exchange Debentures when the conversion
takes place, a portion of the merger consideration received would be taxed as a
payment of such accrued interest.
 
BACKUP TAX WITHHOLDING. Under the federal income tax backup withholding rules,
unless an exemption applies, Laidlaw is required to and will withhold 31% of all
payments to which a Greyhound stockholder or other payee is entitled in the
merger or on the conversion of Greyhound preferred stock or Greyhound Exchange
Debentures, unless the Greyhound stockholder or other payee provides a tax
identification number (social security number, in the case of an individual, or
employer identification number in the case of other stockholders) and certifies
under penalties of perjury that such number is correct. Each Greyhound
stockholder and, if applicable, each other payee, should complete and sign the
substitute Form W-9 which will be part of the letter of transmittal to be
returned to the Paying Agent (or other agent) in order to provide the
information and certification necessary to avoid backup withholding, unless an
applicable exception exists and is proved in a manner satisfactory to the Paying
Agent (or other agent). The exceptions provide that certain Greyhound
stockholders (including, among others, all corporations and certain foreign
individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, however, he or she must submit a signed statement (i.e., Certificate
of Foreign Status on Form W-8) attesting to his or her exempt status. Any
amounts withheld will be allowed as a credit against the holder's federal income
tax liability for such year.
 
THE FEDERAL INCOME TAX DISCUSSION DESCRIBED ABOVE IS INCLUDED FOR GENERAL
INFORMATION PURPOSES ONLY. GREYHOUND STOCKHOLDERS SHOULD CONSULT THEIR OWN TAX
ADVISORS TO DETERMINE THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF
THE MERGER TO THEM IN VIEW OF THEIR OWN PARTICULAR CIRCUMSTANCES.
 
GOVERNMENTAL APPROVALS
 
SURFACE TRANSPORTATION BOARD. Greyhound and Laidlaw are subject to regulation by
the STB. The current laws relating to motor carriers contain a comprehensive
system of control over corporate combinations involving motor carriers or
entities controlling motor carriers (including the merger).
 
   
On November 17, 1998, Laidlaw filed an application with the STB seeking approval
of the merger. On December 17, 1998 (the "Publication Date") the STB published a
summary of the application and provided its tentative grant of approval of the
merger. This publication also served as a notice to the general public of the
proposed merger. The tentative grant of approval became final on February 1,
1999.
    
 
OTHER GOVERNMENTAL FILINGS AND APPROVALS. Contemporaneously with the filing of
the STB application, Laidlaw filed copies of the STB application with the
Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division"). Filing of the STB application
with the FTC and the Antitrust Division and approval by the STB of the STB
application and the merger, exempts the merger from federal and state antitrust
laws. Additionally, the parties are required to make other filings with certain
governmental agencies in connection with the merger, but neither Greyhound nor
Laidlaw believe these filings are material.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
GENERAL. Some of the members of Greyhound's management and the Greyhound Board
may have certain interests in the merger that are different from or in addition
to the interests of stockholders of Greyhound generally. These additional
interests relate to provisions in the merger agreement regarding:
 
   -   certain employment agreements for two executive officers of Greyhound,
 
   -   the benefits under existing change-in-control agreements and severance
       plans,
 
   -   certain actions to be taken in respect of employee benefit plans,
 
   -   the treatment of outstanding Greyhound stock options,
 
   -   the vesting of certain benefits by reason of the merger,
 
   -   the payment of the remaining annual retainer fees for non-employee
       directors, and
 
   -   the indemnification and provision of D&O Insurance for the directors and
       officers of Greyhound.
 
All such additional interests, to the extent material, are described below.
Except as described below, such persons have, to the knowledge of Greyhound, no
material interest in the merger apart from those of the Greyhound stockholders
generally. The Greyhound Board was aware of these interests and considered them,
among other matters, in approving the merger agreement and the transactions
contemplated thereby.
 
EMPLOYMENT AGREEMENTS. Greyhound is a party to an employment agreement with
Craig R. Lentzsch, President and Chief Executive Officer of Greyhound ("Lentzsch
Agreement"). The Lentzsch Agreement has an initial term that expires in November
2001 and renews automatically for additional two-year periods unless either
party gives notice of termination at least 90 days prior to an expiration date.
The Lentzsch Agreement provides for an annual base salary of at least $469,500,
which is subject to annual review and adjustment by the Greyhound Board, annual
incentive bonuses, options to purchase Greyhound common stock and various
employee benefits. The annual incentive bonus will be provided under Greyhound's
Management Incentive Plan ("MIP") with an annual target award of at least 55% of
Mr. Lentzsch's annual base salary for the applicable year. Under the terms of
the MIP as currently in effect, Mr. Lentzsch's annual incentive bonus may not
exceed 110% of his base salary. Employee benefits to be provided include
participation in Greyhound's Section 401(k) plan, medical, dental and vision
plan coverage, participation in Greyhound's supplemental executive retirement
plan ("SERP"), reimbursement for estate, tax and financial planning expenses,
automobile allowance, country club allowance, vacation, life insurance and
long-term disability insurance. Greyhound is required to establish and fully
fund a trust for Mr. Lentzsch's benefit to secure the SERP benefits.
 
If Mr. Lentzsch is terminated by Greyhound "Without Good Cause" or by
"Non-Renewal Without Good Cause" or if Mr. Lentzsch resigns for "Good Reason"
(as such terms are defined in the Lentzsch Agreement), Mr. Lentzsch will receive
a lump-sum cash payment equal to two times the sum of (a) his annual base salary
and (b) the greater of (1) the applicable annual payout of incentive
compensation under the MIP for the plan year immediately prior to the date of
termination or (2) the full annual target award under the MIP based on Mr.
Lentzsch's annual base salary for the plan year in which the termination occurs.
In addition, certain employee benefits previously provided to Mr. Lentzsch will
continue for a two-year period. If at any time prior to a Change of Control (as
defined in the Lentzsch Agreement) Mr. Lentzsch is terminated by reason of "Good
Cause" or "Non-Renewal for Good Cause" or Mr. Lentzsch terminates his employment
"Without
 
                                       34
<PAGE>   39
 
Good Reason" (as such terms are defined in the Lentzsch Agreement), Mr. Lentzsch
has agreed that he will not compete with Greyhound in the manner specified in
the Lentzsch Agreement for a period of one year following the date of
termination.
 
If at any time within two years after a Change of Control Mr. Lentzsch is
terminated by Greyhound Without Good Cause or by Non-Renewal Without Good Cause
or if Mr. Lentzsch resigns for Good Reason or resigns (whether with or without
Good Reason) within 30 days of the first anniversary of the Change of Control
(the "walk at will right"), Mr. Lentzsch will receive a lump-sum cash payment
equal to three times the sum of the amounts described in clauses (a) and (b)
above. In addition, certain employee benefits previously provided to Mr.
Lentzsch will continue for a three-year period. Upon a Change of Control, all
stock options and other incentive awards previously granted to Mr. Lentzsch will
immediately vest and become exercisable. If any payments or benefits provided to
Mr. Lentzsch are determined to be "excess parachute payments" under the Code,
Mr. Lentzsch will be entitled to receive an additional payment (net of income
taxes) to compensate him for any excise tax imposed by the Code. Mr. Lentzsch
has agreed that he will not solicit any of Greyhound's employees to terminate
employment with Greyhound or any of its subsidiaries or to solicit any such
employees to become employed by another entity for a period of one year
following the termination of his employment.
 
Greyhound is also a party to an employment agreement with John W. Haugsland,
Executive Vice President and Chief Operating Officer of Greyhound ("Haugsland
Agreement"). The term of employment of the Haugsland Agreement is the same as
the term described in the Lentzsch Agreement. The Haugsland Agreement provides
for an annual base salary of $305,000, which is subject to annual review and
adjustment by the Greyhound Board, annual incentive bonuses, options to purchase
Greyhound common stock and various employee benefits. The annual incentive bonus
will be provided under the MIP with an annual target award of at least 45% of
Mr. Haugsland's annual base salary for the applicable year. Under the terms of
the MIP as currently in effect, Mr. Haugsland's annual incentive bonus may not
exceed 90% of his base salary. The Haugsland Agreement has provisions regarding
Change of Control, severance, employee benefits, noncompetition and
nonsolicitation substantially similar to those contained in the Lentzsch
Agreement.
 
At Laidlaw's request, prior to the merger, Greyhound and Messrs. Lentzsch and
Haugsland will enter into new employment agreements which will become effective
at the Effective Time replacing their existing employment agreements. If the
merger agreement is terminated prior to the Effective Time, the new employment
agreements will not take effect and the Lentzsch Agreement and Haugsland
Agreement will continue in effect. Mr. Lentzsch's new employment agreement will
provide for an annual base salary of $500,000 and a limitation that his maximum
annual incentive bonus under the MIP (or any successor plan) will not exceed
110% of his base salary. Mr. Haugsland's new employment agreement will provide
for continuation of an annual base salary of $305,000 and a limitation that his
maximum annual incentive bonus under the MIP (or any successor plan) will not
exceed 90% of his base salary. Both new employment agreements provide for the
following:
 
   -   the expansion of their responsibilities after the merger;
 
   -   a pro-rated annual bonus for the period beginning on the Effective Time
       and ending August 31, 1999;
 
   -   continuation of existing employee benefits (except for increases) for at
       least 12 months following the Effective Time, after which a substantially
       equivalent level of benefits must be provided;
 
   -   a revised definition of "Change of Control," which excludes the merger;
 
                                       35
<PAGE>   40
 
   -   the elimination of the walk at will right with respect to the merger;
 
   -   increased severance benefits (other than in connection with a Change of
       Control); and
 
   -   the SERP trust may be funded with a Laidlaw letter of credit.
 
In all other significant respects, the new employment agreements will be the
same as the existing employment agreements.
 
CHANGE IN CONTROL AGREEMENTS. Greyhound has entered into Change in Control
Agreements ("CIC Agreements") with all officers at the vice president level or
higher (other than Messrs. Lentzsch and Haugsland). Under the CIC Agreements, if
a "Change in Control" (as defined in the CIC Agreements) of Greyhound occurs and
the employment of the employee is terminated within two years after the Change
in Control either for "Good Reason" by the employee or "Without Cause" (as such
terms are defined in the CIC Agreements) by Greyhound (or any successor or
assignee), the employee will receive severance benefits, including:
 
   -   base salary and benefits earned and payable through the termination date;
 
   -   the dollar amount of the target payout under the MIP prorated through the
       termination date for the year in which employment is terminated; and
 
   -   a lump-sum cash payment of two times the sum of (x) the employee's
       current annual base salary and (y) the dollar amount of the annual target
       payout under the MIP in effect on the date of the Change in Control.
 
In addition, certain employee benefits (including medical, dental and vision
plan coverage) will continue for a period of two years after the date of
termination. Under the CIC Agreements, if any amount to be paid or provided is
determined to be nondeductible by reason of Section 280G of the Code, the
severance benefits will be reduced to the minimum extent necessary so that
Section 280G does not cause any amount to be nondeductible. Benefits under the
CIC Agreements replace benefits, if any, under any other Greyhound severance
plans. The merger will constitute a Change in Control under the CIC Agreements.
 
POSSIBLE SEVERANCE PAYMENTS. As discussed above, each of Greyhound's executive
officers has an employment or change in control agreement with Greyhound that
entitles that officer to receive a severance payment if his employment is
terminated under certain circumstances within two years following the merger. As
of the date of the Proxy Statement, Laidlaw has not informed Greyhound of its
intention to terminate any of its executive officers following the merger.
However, the estimated severance payments that would be payable to Greyhound's
executive officers if their employment is terminated immediately following the
merger are as follows:

EFFECT OF THE MERGER ON EMPLOYEE BENEFITS AND STOCK PLANS. In addition to the
provisions relating to employment agreements and the CIC Agreements, the merger
agreement contemplates that certain additional actions will be taken in respect
of employee benefits and stock plans in which executive officers of Greyhound
are eligible to participate. Those actions are summarized below.
 
Annual bonuses payable under the 1998 MIP for 1998 were paid to Greyhound's
officers prior to December 31, 1998. Greyhound will provide an annual bonus
program substantially similar to Greyhound's 1998 MIP for the 1999 calendar year
and for at least five calendar years thereafter.
 
Under the terms of the merger agreement, Laidlaw has agreed to continue the SERP
in effect for the 1999 calendar year and for at least five calendar years
thereafter. Under the terms of the merger agreement and as required by the
Lentzsch Agreement and the Haugsland Agreement, Greyhound is establishing and
funding a rabbi trust to secure the payment of the obligations of Greyhound
under the SERP for the benefit of all participants in the SERP. After the
merger, Greyhound will transfer to the rabbi trust an amount not less than the
present value of the SERP obligations secured by such trust and the additional
administrative expenses, in each case, attributable to each fiscal year.
 
Greyhound has agreed to continue, without any amendment or change (except
changes that will increase compensation or benefits or which may be required by
law), all Greyhound employee benefit plans and any other practices and
arrangements that provide compensation or benefits to employees of Greyhound for
a period of at least one year following the merger. See "The Merger -- The
Merger Agreement -- Employee Benefit Matters."
 
In the merger agreement, Laidlaw acknowledges that the merger will constitute a
change in control for purposes of any policy, practice, program or arrangement
that contains a provision relating to a change in control of Greyhound. In
accordance with the terms of the Greyhound stock options, as of the Effective
Time, all Greyhound stock options will vest and become fully exercisable.
 
Greyhound has agreed to use its reasonable best efforts to cause the holders of
Greyhound stock options (other than Greyhound stock options granted under the
Union Option Plan), whether or not exercisable, to cancel their Greyhound stock
options in exchange for an amount in cash equal to $6.50 less the exercise price
of the Greyhound stock options. See "The Merger -- The Merger
Agreement -- Treatment of Greyhound Stock Options."

The value of the unvested stock options is based on the difference between $6.50
per share of Greyhound common stock and the exercise price of the unvested
options.
 
PAYMENT OF REMAINING ANNUAL RETAINER FEES. Subject to approval of the Greyhound
Board, Greyhound expects to pay all of its non-employee directors their annual
retainer for each year remaining on the term of their current directorship. The
annual retainer for non-employee directors is $25,000 (other than the Chairman
of the Board of Directors who receives $45,000). As a result, the non-employee
directors of Greyhound will receive the following amounts: Thomas G. Plaskett
(Chairman), $90,000; Richard J. Caley, $25,000; Linda Chavez, $25,000; A. A.
Meitz, $25,000; Frank L. Nageotte, $50,000; Alfred E. Osborne, Jr., $0; Stephen
M. Peck, $0; and Ernest P. Werlin, $0.
 
FUTURE GRANTS OF LAIDLAW OPTIONS. At the Effective Time, Laidlaw will grant
options to purchase Laidlaw common shares to officers and other employees of
Greyhound. The options to be granted will have an exercise price equal to the
market value of Laidlaw common shares on the date of grant, vest over a
five-year period and expire on the tenth anniversary of the date of grant. The
number of options granted to each person will be comparable to the number of
options granted annually to Laidlaw's officers and employees in similar
positions and as reasonably agreed to by Greyhound and Laidlaw.
 
APPRAISAL RIGHTS
 
Under the DGCL, holders of Greyhound common stock and Greyhound preferred stock
are entitled to appraisal rights in connection with the merger. Any holder of
record of Greyhound common stock or Greyhound preferred stock who objects to the
merger may elect to have his or her shares of Greyhound common stock or
Greyhound preferred stock appraised under the procedures of the DGCL and to be
paid the appraised value of his or her shares. The appraised value of the shares
will not include any value arising from the merger but may include a fair rate
of interest. It is possible that the fair value determined may be more or less
than the merger consideration.
 
                                       38
<PAGE>   43
 
Any holder of Greyhound common stock or Greyhound preferred stock who is
considering exercising his or her appraisal rights is urged to review carefully
the provisions of Section 262 (a copy of which is attached as Appendix C to this
Proxy Statement), particularly with respect to the procedural steps required to
perfect the right of appraisal. The right of appraisal may be lost if the
procedural requirements of Section 262 are not followed exactly. The following
is a summary of the procedures relating to exercise of the right of appraisal,
which should be read in conjunction with the full text of Section 262.
 
Under Section 262, Greyhound is required to notify each Greyhound stockholder
entitled to appraisal rights at least 20 days prior to the special meeting that
such appraisal rights are available. The notice should include a copy of Section
262. THIS PROXY STATEMENT CONSTITUTES SUCH NOTICE TO THE HOLDERS OF GREYHOUND
COMMON STOCK AND GREYHOUND PREFERRED STOCK.
 
A Greyhound stockholder electing to exercise his or her appraisal rights under
Section 262 must deliver to Greyhound a written demand for appraisal before the
vote is taken at the special meeting. The written demand must identify the
Greyhound stockholder and state that the Greyhound stockholder intends to demand
appraisal of his or her shares of Greyhound common stock or Greyhound preferred
stock. A vote against the adoption of the merger agreement or an abstention will
not constitute a demand for appraisal. A Greyhound stockholder electing to take
any of those actions must do so by a separate written demand to Greyhound.
Demands should be mailed or delivered to Greyhound Lines, Inc., 15110 N. Dallas
Parkway, Suite 600, Dallas, Texas 75248, Attention: Secretary. Within 10
calendar days after the Effective Time, Greyhound will notify each Greyhound
stockholder who has made a proper written demand for appraisal and who has not
voted for the adoption of the merger agreement that the merger has been
completed. A vote "For" the adoption of the merger agreement will have the
effect of waiving all appraisal rights.
 
Within 120 calendar days after the Effective Time, Greyhound or any Greyhound
stockholder who has complied with the foregoing notice requirement and the other
requirements of Section 262 may file a petition in the Delaware Court of
Chancery (the "Court") demanding a determination of the fair value of his or her
shares of Greyhound common stock or Greyhound preferred stock. Greyhound has no
obligation to file a petition and does not currently intend to do so. As a
result, any Dissenting Stockholder who wishes to file a petition is advised to
do so on a timely basis. If a petition for appraisal is not filed during the
120-day period, all appraisal rights relating to the Greyhound common stock or
Greyhound preferred stock will terminate. Any Greyhound stockholder may withdraw
a demand for appraisal at any time within 60 calendar days after the Effective
Time (or thereafter with the written consent of Greyhound).
 
If a holder of Greyhound common stock either withdraws his or her demand for
appraisal or has his or her appraisal rights terminated as described above, the
holder of Greyhound common stock will only be entitled to receive the merger
consideration for his or her shares of Greyhound common stock as provided under
the terms of the merger agreement. If a holder of Greyhound preferred stock
either withdraws his or her demand for appraisal or has his or her appraisal
rights terminated as described above, his or her shares of Greyhound preferred
stock will remain outstanding. However, the Greyhound preferred stock will no
longer be convertible into shares of Greyhound common stock after the merger.
Instead, the Greyhound preferred stock will be convertible into the right to
receive $33.33 in cash.
 
Within 120 calendar days after the Effective Time, any stockholder who has
complied with the above-described notice requirements and the other requirements
of Section 262 may request in writing a list of the aggregate number of shares
of Greyhound common stock and Greyhound
 
                                       39
<PAGE>   44
 
preferred stock for which demands for appraisal have been made and the aggregate
number of holders demanding appraisal rights.
 
If a petition is filed by a Dissenting Stockholder, Greyhound will receive
notice from the Court of such filing. Within 20 calendar days after Greyhound
receives notice from the Court, Greyhound must file with the office of the
Register in Chancery in which the petition was filed, a list containing the
names and addresses of all Greyhound stockholders who have demanded appraisal
rights and the names of all Greyhound stockholders who have disagreements with
Greyhound regarding the value of their shares of Greyhound common stock or
Greyhound preferred stock. If a petition is filed by Greyhound, the petition
will be accompanied by a similar list. If ordered by the Court, the Register in
Chancery will give notice of the time and place of the hearing by registered or
certified mail to Greyhound and to each Greyhound stockholder shown on the list.
The notice will also be given by publishing the notice in a newspaper of general
circulation published in Wilmington, Delaware (or any other location the Court
may determine), at least one week before the hearing. The forms of the notices
to be used will be approved by the Court, and all costs related to the
distribution of the notices will be paid by Greyhound.
 
After the Court determines which of the Greyhound stockholders are entitled to
an appraisal under Section 262, the Court will appraise the shares of the
Greyhound common stock and/or Greyhound preferred stock. Following determination
by the Court of the fair value of the shares, Greyhound will pay all Dissenting
Stockholders the appraised value of their shares, together with interest, if
any, upon surrender to Greyhound of their certificates representing Greyhound
common stock or Greyhound preferred stock. The costs of the appraisal proceeding
may be determined by the Court and charged to the parties as the Court deems
equitable in the circumstances. Upon application of a Dissenting Stockholder,
the Court may order all or a portion of the expenses incurred by any Dissenting
Stockholder in connection with the appraisal proceeding, including reasonable
attorneys' fees and the fees and expenses of experts, to be charged pro rata
against the value of all of the shares entitled to an appraisal.
 
After the Effective Time, no Greyhound stockholder who has demanded his or her
appraisal rights as set forth above will be entitled to vote his or her shares
for any purpose or to receive payment of dividends or other distributions on his
shares (except dividends or other distributions payable to Greyhound
stockholders of record at a date prior to the Effective Time). However, after
either withdrawal by a holder of Greyhound preferred stock of his or her demand
for appraisal or the termination of his or her appraisal rights as described
above, such holder will be entitled to vote his or her shares and receive
payment of dividends and other distributions.
 
AMENDMENT TO GREYHOUND RIGHTS AGREEMENT
 
Greyhound amended the Amended and Restated Rights Agreement, dated April 8,
1997, between Greyhound and Mellon Securities Trust Company, as Rights Agent
(the "Greyhound Rights Plan") on October 16, 1998. The amendment provides that
neither the merger nor the merger agreement will cause the rights issued under
the Greyhound Rights Plan to become exercisable.
 
CERTAIN LITIGATION
 
Greyhound has obtained copies of two complaints filed in Delaware Chancery Court
purportedly filed by certain individual Greyhound stockholders on behalf of
themselves and all other Greyhound stockholders. These suits name Greyhound,
each of its directors and Laidlaw as defendants. In the complaints, the
plaintiffs allege, among other things, that (a) the provisions of the merger
agreement
 
                                       40
<PAGE>   45
 
permitting Laidlaw to make the election to pay a portion of the merger
consideration in Laidlaw common shares prior to the fifth trading day before the
special meeting violates Delaware law, (b) the defendant directors breached
their fiduciary duties in approving the merger, and (c) Laidlaw aided and
abetted the breach by members of the Greyhound Board of their fiduciary duties.
The plaintiffs purport to seek orders enjoining the consummation of the merger
or the rescission of the transaction if the merger is completed, damages, costs,
including attorneys' and experts' fees, and other relief. The absence of an
injunction, among other things, is a condition to Greyhound's and Laidlaw's
obligation to complete the merger. See "The Merger -- The Merger Agreement --
Conditions to the Merger." Greyhound has not filed answers to these suits, as
the time period for doing so has been extended. Greyhound intends to defend
these suits vigorously.

                    BENEFICIAL OWNERSHIP OF GREYHOUND STOCK
 
The following table sets forth the beneficial ownership of the outstanding
shares of Greyhound common stock and Greyhound preferred stock as of January 31,
1999 (except as noted below), held by persons believed by Greyhound to
beneficially own more than 5% of the outstanding shares of the Greyhound common
stock or Greyhound preferred stock, by directors of Greyhound, by Greyhound's
chief executive officer and its other four most highly compensated executive
officers and by all the directors and executive officers of Greyhound as a
group, and the percentage of the outstanding shares of Greyhound common stock
and Greyhound preferred stock represented thereby. Except as otherwise noted
below, each of the directors, executive officers and 5% stockholders has sole
voting and investment power with respect to all shares beneficially owned by
them.

     THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER (this "Agreement"),
dated as of October 16, 1998 and amended and restated as of November 5, 1998, is
among Greyhound Lines, Inc., a Delaware corporation (the "Company"), Laidlaw
Inc., a Canadian corporation ("Parent"), and Laidlaw Transit Acquisition Corp.,
a Delaware corporation and a wholly owned subsidiary of Parent ("Acquisition").
For the purposes of this Agreement, the date of this Agreement shall be deemed
to be October 16, 1998.
 
     WHEREAS, the Boards of Directors of Parent and Acquisition have each
approved the merger of Acquisition with and into the Company (the "Merger") upon
the terms and subject to the conditions set forth herein;
 
     WHEREAS, the Board of Directors of the Company (the "Board") (i) determined
that the Merger and the transactions contemplated thereby are fair to and in the
best interests of the Company and its stockholders and (ii) on the terms 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
the Agreement on the terms and subject to the conditions set forth below.
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, the
Company, Parent and Acquisition hereby agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     SECTION 1.1  The Merger.
 
     (a) Effective Time. At the Effective Time (as defined below), and 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 and into
the Company, the separate corporate existence of Acquisition shall cease, and
the Company shall continue as the surviving corporation. The Company as the
surviving corporation after the Merger is hereinafter sometimes referred to as
the "Surviving Corporation."
 
     (b) Closing. Unless this Agreement shall have been terminated and the
transactions herein contemplated shall have been abandoned pursuant to Section
7.1, and subject to the satisfaction or waiver of the conditions set forth in
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
in writing by the parties hereto (the "Closing Date").
 
     SECTION 1.2  Effective Time. As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the parties
hereto shall cause the Merger to be consummated by filing a certificate of
merger as contemplated by the Delaware Law (the "Certificate of Merger"),
together with any required related certificates, with the Secretary of State of
the State of Delaware,
 
                                       A-6
<PAGE>   56
 
in such form as required by, and executed in accordance with the relevant
provisions of, the Delaware Law (the time of such filing being the "Effective
Time").
 
     SECTION 1.3  Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of the Delaware Law. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time all the property,
rights, privileges, powers and franchises of the Company and Acquisition shall
vest in the Surviving Corporation, and all debts, liabilities, obligations and
duties of the Company and Acquisition shall become the debts, liabilities,
obligations and duties of the Surviving Corporation.
 
     SECTION 1.4  Certificate of Incorporation, By-Laws.
 
     (a) Certificate of Incorporation. Unless otherwise determined by Parent
prior to the Effective Time, at the Effective Time the Certificate of
Incorporation of the Surviving Corporation shall be amended to become identical
to the Certificate of Incorporation of Acquisition, as in effect immediately
prior to the Effective Time; provided, however, that such amendment to the
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 the
Company with respect to the Company Preferred Shares and (iv) the provisions
regarding indemnification and insurance as described in Section 4.12.
 
     (b) By-Laws. The By-Laws of Acquisition, as in effect immediately prior to
the Effective Time, shall be the By-Laws of the Surviving Corporation until
thereafter amended as provided by the Delaware Law, the Certificate of
Incorporation of the Surviving Corporation and such By-Laws.
 
     SECTION 1.5  Directors and Officers. The directors of Acquisition
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation, and, except as set forth
in Section 1.5 of the Company Disclosure Schedule, the officers of the Company
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, in each case until their respective successors are duly
elected or appointed and qualified.
 
     SECTION 1.6  Effect on Capital Stock. At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Acquisition, the
Company or the holders of any of the following securities:
 
          (a) Conversion of 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, par value $.01 per share, of the Company (each a "Company
        Preferred Share" and collectively, the "Company Preferred Shares")
        issued and outstanding immediately prior to the Effective Time shall
        remain issued and outstanding and have, as to the Surviving Corporation,
        the
 
                                       A-7
<PAGE>   57
 
        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 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
 
                                       A-8
<PAGE>   58
 
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 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 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).
 
                                       A-9
<PAGE>   59
 
          (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 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.
 
                                      A-10
<PAGE>   60
 
     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;
 
          (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 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 of the Company's Series A
Junior Preferred Stock were issued
 
                                      A-12
<PAGE>   62
 
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.
 
     SECTION 2.5  No Conflict; Required Filings and Consents.
 
     (a) Section 2.5(a) of the Company Disclosure Schedule includes a list of
all agreements to which the Company or any of its subsidiaries is a party or by
which any of them is bound which, as of the date of this Agreement: (i) are
required to be filed as "material contracts" with the SEC pursuant to the
requirements of the Exchange Act; (ii) under which the consequences of a

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

     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

<PAGE>   67

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

     (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 for all taxable periods and portions thereof through the date
     of such 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.
 
     SECTION 2.15  Intellectual Property. Except as set forth in Section 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 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 the Company and
its subsidiaries as currently conducted, except as would not have a Material
Adverse Effect.
 
     SECTION 2.16  Rights Agreement. Concurrently with the execution and
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,
1997 between the Company and Mellon Securities Trust Company, as Rights Agent
(the "Rights Agreement") inapplicable to the Merger and the other transactions
contemplated by this Agreement and (ii) ensure that (a) neither Parent or
Acquisition is an Acquiring Person (as defined in the Rights Agreement) pursuant
to the Rights Agreement and (b) a Distribution Date (as defined in the Rights
Agreement) does not occur solely by reason of the execution of this Agreement,
the consummation of the Merger or the consummation of the other transactions
contemplated by this Agreement.
 
     SECTION 2.17  Opinion of Financial Advisor. The Board has received the
opinion of the Company's financial advisor, Bear, Stearns & Co. Inc. ("Bear
Stearns"), to the effect that, as of the date of this Agreement, the Merger
Consideration to be received by the holders of Company Common Shares and Company
Preferred Shares (other than Parent and its affiliates) pursuant to the Merger
is fair, from a financial point of view, to such holders.
 
     SECTION 2.18  Brokers. No broker, finder or investment banker (other than
Bear Stearns) 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 the Company. The Company has heretofore
furnished to Parent a complete and correct copy of all agreements 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 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,
the execution and delivery of this Agreement by Parent and Acquisition do not,
and the performance of this Agreement by Parent and Acquisition will not, (i)
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
to Parent or any of its subsidiaries or by which its or any of their respective

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

     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.
 
     (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
 
                                      A-24

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.

     (a) The Certificate of Incorporation and By-Laws of the Surviving

exculpation and advancement of expenses set forth in the Certificate of
Incorporation and By-Laws of the Company, which provisions shall not be amended,
repealed or otherwise modified for a period of three years from the Effective

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

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
 
                                      A-28
<PAGE>   78
 
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,

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

in the past controlled, any present or former director, officer or employee of
the Company or any of its subsidiaries.

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.

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 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 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
 
                                      A-30
<PAGE>   80
 
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.

covenants hereunder.
 
     SECTION 5.2  No Solicitation.

merger, sale of substantial assets, sale of shares of capital stock (including

subsidiaries of the Company other than the Merger (any of the foregoing
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
Section 5.2(a) shall prevent the Company or any representative thereof from
furnishing or causing to be furnished, information and directing the Company,
its directors, officers, employees, representatives or agents to furnish
information, in each case pursuant

<PAGE>   83

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 or
for access to the properties, books or records of the Company or any 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

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

confidentiality agreement to which the Company is a party.

representative retained by the Company are aware of the restrictions described

<PAGE>   85
 
     (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

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);

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

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

upon the first to occur of the following events:
 
          (i) the termination of this Agreement pursuant to Section 7.1(e); or

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

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

                            BEAR STEARNS LETTERHEAD
 
As of October 16, 1998
 
Board of Directors
Greyhound Lines, Inc.
15110 North Dallas Parkway, Suite 600
Dallas, TX 75248
 
             Attention:  Thomas G. Plaskett, Chairman of the Board
            Craig R. Lentzsch, Chief Executive Officer
 
Ladies and Gentlemen:
 
We understand that Greyhound Lines, Inc. ("Greyhound") and Laidlaw Inc.
("Laidlaw") have entered into an Agreement and Plan of Merger dated October 16,
1998 (as amended and restated as of November 5, 1998, the "Agreement"), pursuant
to which a wholly-owned subsidiary of Laidlaw will acquire Greyhound in a merger
transaction (the "Transaction") whereby each share of Greyhound common stock
will be converted into the right to receive $6.50 in aggregate value (the
"Transaction Consideration"), and whereby each share of Greyhound 8.5%
convertible exchangeable preferred stock will remain outstanding pursuant to the
terms of such securities. The Transaction Consideration shall be payable in
cash, subject to Laidlaw's option to satisfy up to $4.00 of the Transaction
Consideration with shares of Laidlaw common stock. The amount, if any, of
Laidlaw common stock to be offered as part of the Transaction Consideration will
be determined in a manner set forth in the Agreement.
 
You have asked us to render our opinion as to whether the Transaction
Consideration is fair, from a financial point of view, to the stockholders of
Greyhound.
 
In the course of our analyses for rendering this opinion, we have:
 
      1.  reviewed the Agreement;
 
      2.  reviewed Greyhound's Annual Reports to Shareholders and Annual Reports
          on Form 10-K for the fiscal years ended December 31, 1995 through
          1997, and its Quarterly Reports on Form 10-Q for the periods ended
          March 31, 1998 and June 30, 1998;
 
      3.  reviewed certain operating and financial information, including
          internal financial projections, provided to us and reviewed for us by
          management relating to Greyhound's business and prospects;
 
      4.  met with certain members of Greyhound's senior management to discuss
          its operations, historical financial statements and future prospects;
 
                                       B-1

      5.  reviewed Laidlaw's Annual Reports to Shareholders and Annual Reports
          on Form 10-K for the fiscal years ended August 31, 1995 through 1997,
          its Quarterly Reports on Form 10-Q for the periods ended November 30,
          1997, February 28, 1998 and May 31, 1998, and a draft of its
          consolidated financial statements for the fiscal year ended August 31,
          1998;
 
      6.  reviewed certain operating and financial information, including
          internal financial projections, provided to us and reviewed for us by
          management relating to Laidlaw's business and prospects;
 
      7.  met with certain members of Laidlaw's senior management to discuss its
          operations, historical financial statements and future prospects;
 
      8.  reviewed the historical prices and trading volumes of the common
          shares of Greyhound and Laidlaw;
 
      9.  reviewed publicly available financial data, stock market performance
          data and valuation parameters of companies which we deemed generally
          comparable to Greyhound and Laidlaw;
 
     10.  reviewed the financial terms of recent acquisitions of companies which
          we deemed generally comparable to the Transaction; and
 
     11.  conducted such other studies, analyses, inquiries and investigations
          as we deemed appropriate.
 
In the course of our review, we have relied upon and assumed, without assuming
any responsibility for independent verification, the accuracy and completeness
of all of the financial and other information (including estimates and
projections) provided to, discussed with, or reviewed by or for us by Greyhound
and Laidlaw or publicly available for purposes of this opinion, including,
without limitation, the adequacy of Laidlaw's reserves relating to loss
contingencies. We have further relied upon the assurances of the senior
managements of Greyhound and Laidlaw that they are unaware of any facts that
would make the information, estimates and projections provided to, discussed
with, or reviewed by or for us incomplete, inaccurate or misleading. With
respect to Greyhound's and Laidlaw's internal financial projections and
estimates of potential synergies that could be achieved upon consummation of the
Transaction, we have assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the senior
managements of Greyhound and Laidlaw as to the expected future performance of
Greyhound and Laidlaw, respectively. We express no view as to such information,
or the assumptions on which they were based. For purposes of rendering our
opinion, we have further assumed that the current matter before the United
States Tax Court will not have a material adverse effect on Laidlaw's financial
condition, results of operations, business or prospects. In arriving at our
opinion, we have not performed or obtained any independent appraisal of the
assets or liabilities of Greyhound or Laidlaw, nor have we been furnished with
any such appraisals. Our opinion is necessarily based on economic, market and
other conditions, and the information made available to us, as of October 16,
1998 (except with respect to the Agreement which is amended and restated as of
November 5, 1998).
 
For purposes of rendering our opinion we have assumed, in all respects material
to our analysis, that the representations and warranties of each party contained
in the Agreement are true and correct, that each party will perform all of the
covenants and agreements required to be performed by it under
 
                                       B-2
<PAGE>   94
Greyhound Lines, Inc.
As of October 16, 1998
Page  3
 
the Agreement and all conditions to the consummation of the Transaction will be
satisfied without waiver thereof.
 
We do not express any opinion as to the price or range of prices at which shares
of common stock of Laidlaw may trade subsequent to the consummation of the
Transaction.
 
Bear Stearns is a nationally recognized investment banking firm and has
previously provided investment banking services to Greyhound and Laidlaw. In the
ordinary course of business, Bear Stearns may actively trade the equity
securities of Greyhound and Laidlaw for its own account and for the accounts of
its customers and, accordingly, may at any time hold a long or short position in
such securities.
 
It is understood that this letter is intended for the benefit and use of the
Board of Directors of Greyhound in its evaluation of the Transaction. This
letter does not constitute a recommendation to the Board of Directors of
Greyhound or any stockholders of Greyhound as to how to vote in connection with
the Transaction. This opinion does not address Greyhound's underlying business
decision to pursue the Transaction. This letter is not to be used for any other
purpose, or reproduced, disseminated, quoted from or referred to at any time, in
whole or in part, without our prior written consent; provided, however, that
this letter may be included in its entirety in any proxy statement/prospectus to
be distributed to the stockholders of Greyhound in connection with the
Transaction.
 
We have acted as a financial advisor to Greyhound in connection with the
Transaction and will receive a fee for such services.
 
Based on and subject to the foregoing, it is our opinion that as of the date
hereof the Transaction Consideration is fair, from a financial point of view, to
the stockholders of Greyhound.
 
Very truly yours,
 
BEAR, STEARNS & CO. INC.

                        Delaware General Corporation Law
                                  Section 262
 
(a) Any stockholder of a corporation of this State who holds shares of stock on
    the date of the making of a demand pursuant to subsection (d) of this
    section with respect to such shares, who continuously holds such shares
    through the effective date of the merger or consolidation, who has otherwise
    complied with subsection (d) of this section and who has neither voted in
    favor of the merger or consolidation nor consented thereto in writing
    pursuant to sec. 228 of this title shall be entitled to an appraisal by the
    Court of Chancery of the fair value of the stockholder's shares of stock
    under the circumstances described in subsections (b) and (c) of this
    section. As used in this section, the word "stockholder" means a holder of
    record of stock in a stock corporation and also a member of record of a
    nonstock corporation; the words "stock" and "share" mean and include what is
    ordinarily meant by those words and also membership or membership interest
    of a member of a nonstock corporation; and the words "depository receipt"
    mean a receipt or other instrument issued by a depository representing an
    interest in one or more shares, or fractions thereof, solely of stock of a
    corporation, which stock is deposited with the depository.
 
(b) Appraisal rights shall be available for the shares of any class or series of
    stock of a constituent corporation in a merger or consolidation to be
    effected pursuant to sec. 251 (other than a merger effected pursuant to
    sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263
    or sec. 264 of this title:
 
     (1) Provided, however, that no appraisal rights under this section shall be
         available for the shares of any class or series of stock, which stock,
         or depository receipts in respect thereof, at the record date fixed to
         determine the stockholders entitled to receive notice of and to vote at
         the meeting of stockholders to act upon the agreement of merger or
         consolidation, were either (i) listed on a national securities exchange
         or designated as a national market system security on an interdealer
         quotation system by the National Association of Securities Dealers,
         Inc. or (ii) held of record by more than 2,000 holders; and further
         provided that no appraisal rights shall be available for any shares of
         stock of the constituent corporation surviving a merger if the merger
         did not require for its approval the vote of the stockholders of the
         surviving corporation as provided in subsection (f) of sec. 251 of this
         title.
 
     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
         under this section shall be available for the shares of any class or
         series of stock of a constituent corporation if the holders thereof are
         required by the terms of an agreement of merger or consolidation
         pursuant to sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title
         to accept for such stock anything except:
 
        a. Shares of stock of the corporation surviving or resulting from such
           merger or consolidation, or depository receipts in respect thereof;
 
        b. Shares of stock of any other corporation, or depository receipts in
           respect thereof, which shares of stock (or depository receipts in
           respect thereof) or depository receipts at the effective date of the
           merger or consolidation will be either listed on a national
           securities exchange or designated as a national market system
           security on an interdealer quotation system by the National
           Association of Securities Dealers, Inc. or held of record by more
           than 2,000 holders;
 
                                       C-1
<PAGE>   96
 
        c. Cash in lieu of fractional shares or fractional depository receipts
           described in the foregoing subparagraphs a. and b. of this paragraph;
           or
 
        d. Any combination of the shares of stock, depository receipts and cash
           in lieu of fractional shares or fractional depository receipts
           described in the foregoing subparagraphs a., b. and c. of this
           paragraph.
 
     (3) In the event all of the stock of a subsidiary Delaware corporation
         party to a merger effected under sec. 253 of this title is not owned by
         the parent corporation immediately prior to the merger, appraisal
         rights shall be available for the shares of the subsidiary Delaware
         corporation.
 
(c) Any corporation may provide in its certificate of incorporation that
    appraisal rights under this section shall be available for the shares of any
    class or series of its stock as a result of an amendment to its certificate
    of incorporation, any merger or consolidation in which the corporation is a
    constituent corporation or the sale of all or substantially all of the
    assets of the corporation. If the certificate of incorporation contains such
    a provision, the procedures of this section, including those set forth in
    subsections (d) and (e) of this section, shall apply as nearly as is
    practicable.
 
(d) Appraisal rights shall be perfected as follows:
 
     (1) If a proposed merger or consolidation for which appraisal rights are
         provided under this section is to be submitted for approval at a
         meeting of stockholders, the corporation, not less than 20 days prior
         to the meeting, shall notify each of its stockholders who was such on
         the record date for such meeting with respect to shares for which
         appraisal rights are available pursuant to subsection (b) or (c) hereof
         that appraisal rights are available for any or all of the shares of the
         constituent corporations, and shall include in such notice a copy of
         this section. Each stockholder electing to demand the appraisal of such
         stockholder's shares shall deliver to the corporation, before the
         taking of the vote on the merger or consolidation, a written demand for
         appraisal of such stockholder's shares. Such demand will be sufficient
         if it reasonably informs the corporation of the identity of the
         stockholder and that the stockholder intends thereby to demand the
         appraisal of such stockholder's shares. A proxy or vote against the
         merger or consolidation shall not constitute such a demand. A
         stockholder electing to take such action must do so by a separate
         written demand as herein provided. Within 10 days after the effective
         date of such merger or consolidation, the surviving or resulting
         corporation shall notify each stockholder of each constituent
         corporation who has complied with this subsection and has not voted in
         favor of or consented to the merger or consolidation of the date that
         the merger or consolidation has become effective; or
 
     (2) If the merger or consolidation was approved pursuant to sec. 228 or
         sec. 253 of this title, each constituent corporation, either before the
         effective date of the merger or consolidation or within ten days
         thereafter, shall notify each of the holders of any class or series of
         stock of such constituent corporation who are entitled to appraisal
         rights of the approval of the merger or consolidation and that
         appraisal rights are available for any or all shares of such class or
         series of stock of such constituent corporation, and shall include in
         such notice a copy of this section; provided that, if the notice is
         given on or after the effective date of the merger or consolidation,
         such notice shall be given by the surviving or resulting corporation to
         all such holders of any class or series of stock of a constituent
         corporation that are
 
                                       C-2
<PAGE>   97
 
        entitled to appraisal rights. Such notice may, and, if given on or after
        the effective date of the merger or consolidation, shall, also notify
        such stockholders of the effective date of the merger or consolidation.
        Any stockholder entitled to appraisal rights may, within 20 days after
        the date of mailing of such notice, demand in writing from the surviving
        or resulting corporation the appraisal of such holder's shares. Such
        demand will be sufficient if it reasonably informs the corporation of
        the identity of the stockholder and that the stockholder intends thereby
        to demand the appraisal of such holder's shares. If such notice did not
        notify stockholders of the effective date of the merger or
        consolidation, either (i) each such constituent corporation shall send a
        second notice before the effective date of the merger or consolidation
        notifying each of the holders of any class or series of stock of such
        constituent corporation that are entitled to appraisal rights of the
        effective date of the merger or consolidation or (ii) the surviving or
        resulting corporation shall send such a second notice to all such
        holders on or within 10 days after such effective date; provided,
        however, that if such second notice is sent more than 20 days following
        the sending of the first notice, such second notice need only be sent to
        each stockholder who is entitled to appraisal rights and who has
        demanded appraisal of such holder's shares in accordance with this
        subsection. An affidavit of the secretary or assistant secretary or of
        the transfer agent of the corporation that is required to give either
        notice that such notice has been given shall, in the absence of fraud,
        be prima facie evidence of the facts stated therein. For purposes of
        determining the stockholders entitled to receive either notice, each
        constituent corporation may fix, in advance, a record date that shall be
        not more than 10 days prior to the date the notice is given, provided,
        that if the notice is given on or after the effective date of the merger
        or consolidation, the record date shall be such effective date. If no
        record date is fixed and the notice is given prior to the effective
        date, the record date shall be the close of business on the day next
        preceding the day on which the notice is given.
 
(e) Within 120 days after the effective date of the merger or consolidation, the
    surviving or resulting corporation or any stockholder who has complied with
    subsections (a) and (d) hereof and who is otherwise entitled to appraisal
    rights, may file a petition in the Court of Chancery demanding a
    determination of the value of the stock of all such stockholders.
    Notwithstanding the foregoing, at any time within 60 days after the
    effective date of the merger or consolidation, any stockholder shall have
    the right to withdraw such stockholder's demand for appraisal and to accept
    the terms offered upon the merger or consolidation. Within 120 days after
    the effective date of the merger or consolidation, any stockholder who has
    complied with the requirements of subsections (a) and (d) hereof, upon
    written request, shall be entitled to receive from the corporation surviving
    the merger or resulting from the consolidation a statement setting forth the
    aggregate number of shares not voted in favor of the merger or consolidation
    and with respect to which demands for appraisal have been received and the
    aggregate number of holders of such shares. Such written statement shall be
    mailed to the stockholder within 10 days after such stockholder's written
    request for such a statement is received by the surviving or resulting
    corporation or within 10 days after expiration of the period for delivery of
    demands for appraisal under subsection (d) hereof, whichever is later.
 
(f) Upon the filing of any such petition by a stockholder, service of a copy
    thereof shall be made upon the surviving or resulting corporation, which
    shall within 20 days after such service file in the office of the Register
    in Chancery in which the petition was filed a duly verified list containing
    the names and addresses of all stockholders who have demanded payment for
    their shares and with whom agreements as to the value of their shares have
    not been reached by the
 
                                       C-3
<PAGE>   98
 
    surviving or resulting corporation. If the petition shall be filed by the
    surviving or resulting corporation, the petition shall be accompanied by
    such a duly verified list. The Register in Chancery, if so ordered by the
    Court, shall give notice of the time and place fixed for the hearing of such
    petition by registered or certified mail to the surviving or resulting
    corporation and to the stockholders shown on the list at the addresses
    therein stated. Such notice shall also be given by 1 or more publications at
    least 1 week before the day or the hearing, in a newspaper of general
    circulation published in the City of Wilmington, Delaware or such
    publication as the Court deems advisable. The forms of the notices by mail
    and by publication shall be approved by the Court, and the costs thereof
    shall be borne by the surviving or resulting corporation.
 
(g) At the hearing on such petition, the Court shall determine the stockholders
    who have complied with this section and who have become entitled to
    appraisal rights. The Court may require the stockholders who have demanded
    an appraisal for their shares and who hold stock represented by certificates
    to submit their certificates of stock to the Register in Chancery for
    notation thereon of the pendency of the appraisal proceedings; and if any
    stockholder fails to comply with such direction, the Court may dismiss the
    proceedings as to such stockholder.
 
(h) After determining the stockholders entitled to an appraisal, the Court shall
    appraise the shares, determining their fair value exclusive of any element
    of value arising from the accomplishment or expectation of the merger or
    consolidation, together with a fair rate of interest, if any, to be paid
    upon the amount determined to be the fair value. In determining such fair
    value, the Court shall take into account all relevant factors. In
    determining the fair rate of interest, the Court may consider all relevant
    factors, including the rate of interest which the surviving or resulting
    corporation would have had to pay to borrow money during the pendency of the
    proceeding. Upon application by the surviving or resulting corporation or by
    any stockholder entitled to participate in the appraisal proceeding, the
    Court may, in its discretion, permit discovery or other pretrial proceedings
    and may proceed to trial upon the appraisal prior to the final determination
    of the stockholder entitled to an appraisal. Any stockholder whose name
    appears on the list filed by the surviving or resulting corporation pursuant
    to subsection (f) of this section and who has submitted such stockholder's
    certificates of stock to the Register in Chancery, if such is required, may
    participate fully in all proceedings until it is finally determined that
    such stockholder is not entitled to appraisal rights under this section.
 
(i) The Court shall direct the payment of the fair value of the shares, together
    with interest, if any, by the surviving or resulting corporation to the
    stockholders entitled thereto. Interest may be simple or compound, as the
    Court may direct. Payment shall be so made to each such stockholder, in the
    case of holders of uncertificated stock forthwith, and the case of holders
    of shares represented by certificates upon the surrender to the corporation
    of the certificates representing such stock. The Court's decree may be
    enforced as other decrees in the Court of Chancery may be enforced, whether
    such surviving or resulting corporation be a corporation of this State or of
    any state.
 
(j) The costs of the proceeding may be determined by the Court and taxed upon
    the parties as the Court deems equitable in the circumstances. Upon
    application of a stockholder, the Court may order all or a portion of the
    expenses incurred by any stockholder in connection with the appraisal
    proceeding, including, without limitation, reasonable attorney's fees and
    the fees and expenses of experts, to be charged pro rata against the value
    of all the shares entitled to an appraisal.
 
(k) From and after the effective date of the merger or consolidation, no
    stockholder who has demanded appraisal rights as provided in subsection (d)
    of this section shall be entitled to vote
 
                                       C-4
<PAGE>   99
 
    such stock for any purpose or to receive payment of dividends or other
    distributions on the stock (except dividends or other distributions payable
    to stockholders of record at a date which is prior to the effective date of
    the merger or consolidation); provided, however, that if no petition for an
    appraisal shall be filed within the time provided in subsection (e) of this
    section, or if such stockholder shall deliver to the surviving or resulting
    corporation a written withdrawal of such stockholder's demand for an
    appraisal and an acceptance of the merger or consolidation, either within 60
    days after the effective date of the merger or consolidation as provided in
    subsection (e) of this section or thereafter with the written approval of
    the corporation, then the right of such stockholder to an appraisal shall
    cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
    of Chancery shall be dismissed as to any stockholder without the approval of
    the Court, and such approval may be conditioned upon such terms as the Court
    deems just.
 
(l) The shares of the surviving or resulting corporation to which the shares of
    such objecting stockholders would have been converted had they assented to
    the merger or consolidation shall have the status of authorized and unissued
    shares of the surviving or resulting corporation.
