                     GREYHOUND LINES, INC. AND SUBSIDIARIES
               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 2000
                                   (UNAUDITED)

1.  INTERIM CONSOLIDATED FINANCIAL STATEMENTS

In the opinion of management, the unaudited Interim Consolidated Financial
Statements of Greyhound Lines, Inc. and Subsidiaries (the "Company") include all
adjustments, consisting of only normal recurring adjustments, necessary to
present fairly the Company's financial position as of June 30, 2000, the results
of its operations for the three and six months ended June 30, 2000 and 1999 and
cash flows for the six months ended June 30, 2000 and 1999 and have been
prepared on a going concern basis which contemplates the realization of assets
and the settlement of liabilities and commitments in the normal course of
operations. Due to the seasonality of the Company's operations, the results of
its operations for the interim period ended June 30, 2000 may not be indicative
of total results for the full year. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to the
rules and regulations promulgated by the Securities and Exchange Commission. The
unaudited Interim Consolidated Financial Statements should be read in
conjunction with the audited Consolidated Financial Statements of Greyhound
Lines, Inc. and Subsidiaries and accompanying notes for the year ended December
31, 1999. Certain reclassifications have been made to the prior period
statements to conform them to the current year presentation. For the three and
six months ended June 30, 2000 and 1999, the Company's comprehensive income
(loss) approximated its' net income (loss).

2.  COMMITMENTS AND CONTINGENCIES

The Company's principal sources of liquidity are cash flow from operations and,
previously, funds provided by the Company's parent, Laidlaw Inc. ("Laidlaw"). In
its Quarterly Report on Form 10-Q for the period ended May 31, 2000 (the
"Laidlaw Form 10-Q"), Laidlaw reported that it had declared an interest payment
moratorium on all advances under its syndicated banking facility (the "Laidlaw
Facility") and on certain of its debentures totaling $1.954 billion (the
"Laidlaw Debentures"). As a consequence of the Laidlaw Facility covenant
violations and interest payment moratorium, the Laidlaw Facility and the Laidlaw
Debentures have become due on demand. Laidlaw is endeavoring to renegotiate and
restructure the Laidlaw Facility and Laidlaw Debentures. In the Laidlaw Form
10-Q, Laidlaw further reported that should repayment be demanded for the Laidlaw
Facility and/or the Laidlaw Debentures, Laidlaw may not be able to satisfy these
obligations, nor other obligations which become due in the normal course of
operations and may not be able to continue to operate as a going concern.
Additionally, Laidlaw has advised the Company that cash funding, after August 1,
2000, would be limited to the cash flow generated by the Company from its
operations and that additional funds from Laidlaw would not be available.
Laidlaw further requested and authorized the Company to seek additional funding
from outside financing sources for its seasonal cash requirements and capital
expenditure programs. The Company is in the early stages of seeking this
financing and there can be no assurances that alternate sources of financing, in
amounts necessary to meet Company's needs, will be available, and if available,
that the cost of such financing will not materially exceed the cost currently
experienced by the Company. Should alternate sources not be available or not be
sufficient to meet the Company's needs, the Company may be required to curtail
or defer non-essential or essential capital and operating expenditures and may
not be able to satisfy its obligations as they become due in the normal course
of operations and may not be able to continue to operate as a going concern. As
a result, the Company may not be able to realize its assets and settle its
liabilities in the normal course of operations.

The Company's primary uses of cash are for operating activities, capital
expenditures and debt service. As of June 30, 2000, the Company had $176.1
million of long-term indebtedness (including a current portion of $6.1 million,
excluding $29.3 in payments due to former holders of the Company's Redeemable
Preferred Stock, discussed below), principally, its 11-1/2% Senior Notes due
2007 in the amount of $150 million. Interest on the Senior Notes is payable in
semi-annual installments of $8.6 million, each April and October. The Company
has ordered ninety (90) new motor coaches from Motor Coach Industries
International, of which 33 were delivered as of the date of this report, with
the remaining buses to be delivered this fall. Payment for the buses, totaling
$27.5 million, is payable to Motor Coach in December 2000. As indicated above,
the Company will be seeking interim and permanent lease or purchase money
financing for these buses.

At March 31, 2000, the Company had 1,344,850 shares of Redeemable Preferred
Stock outstanding. Each share of Redeemable Preferred Stock is convertible, at
the option of the holder, into $33.33 in cash. On April 19, 2000, Laidlaw
instructed the Company that due to the limitation of funding available to
Laidlaw from its bank syndicate, it was not practical to make payment for



                                       8
<PAGE>   9


Redeemable Preferred Stock presented for conversion. Accordingly, Laidlaw
advised the Company's transfer agent to reject shares that have been presented
for conversion and to return them to the holders.

On May 9, 2000, a lawsuit was filed by two holders of Redeemable Preferred Stock
alleging: (i) that the Company, in violation of federal securities laws,
materially misrepresented facts, and omitted reference to material facts, with
respect to the conversion rights of holders of the Redeemable Preferred Stock
and (ii) that the Company was in breach of the rights of holders of Redeemable
Preferred Stock as contained in the Company's Restated Certificate of
Incorporation. The suit sought recovery from the Company of the conversion
payments relating to the Redeemable Preferred Stock held by the plaintiffs,
totaling $17.4 million, costs, attorneys' fees and interest. Laidlaw was also
named as a defendant in the suit. Plaintiffs alleged that Laidlaw tortiously
interfered with the Company's obligations to the plaintiffs and sought
injunctive relief, actual and punitive damages, costs, attorneys' fees and
interest. The suit, Reliant Trading and Deutsche Bank AG, London Branch v.
Greyhound Lines, Inc. and Laidlaw Inc., is pending in the United States District
Court for the Eastern District of Wisconsin, Civil Action 00-C-0656. On May 31,
2000, another holder of Redeemable Preferred Stock, Silverado Arbitrage Trading
Ltd., filed a motion with the Court seeking to intervene in the lawsuit.
Silverado sought recovery of conversion payments totaling $4.9 million, costs,
attorneys' fees and interest from the Company and sought injunctive relief,
actual and punitive damages, costs, attorneys' fees and interest as to Laidlaw.

On June 8 and 15, 2000, the Company and Laidlaw reached separate confidential
settlements with the plaintiffs and Silverado whereby they will receive payments
from the Company of the conversion amounts for their Redeemable Preferred Stock,
together with interest accruing from May 1, 2000, in weekly installments through
August 31, 2000. Pending fulfillment of the Company's obligations under the
settlements, the foregoing litigation has been stayed.

Subsequently, the Company and Laidlaw entered into agreements or otherwise made
payment arrangements with additional holders of the Redeemable Preferred Stock
that had previously tendered their shares for conversion whereby such parties
would receive their conversion proceeds in installment payments through August
31, 2000. During the three-month period ending June 30, 2000, the Company made
$8.3 million in conversion payments to the converting holders and, as of June
30, 2000, recorded the remaining amounts payable under the agreements, totaling
$29.3 million, as a current liability.

Since June 30, 2000, the Company has made $19.7 million in additional conversion
payments to these parties and, as of August 11, 2000, $9.6 million remained
payable. As of the date of this report, the Company has made all required
payments called for under the agreements.

On August 1, 2000, the Company paid a quarterly dividend to holders of the
Redeemable Preferred Stock.

ITEM 2. MANAGEMENT'S NARRATIVE ANALYSIS OF RESULTS OF OPERATIONS

GENERAL

Greyhound is the only nationwide provider of scheduled intercity bus
transportation services in the United States. The Company's primary business
consists of scheduled passenger service, package express service and food
services at certain terminals. The Company's consolidated operations include a
nationwide network of terminal and maintenance facilities, a fleet of
approximately 2,900 buses and approximately 1,800 sales outlets.

The Company's business is seasonal in nature and generally follows the pattern
of the travel industry as a whole, with peaks during the summer months and the
Thanksgiving and Christmas holiday periods. As a result, the Company's operating
cash flows are also seasonal with a disproportionate amount of the Company's
annual operating cash flows being generated during the peak travel periods. The
day of the week on which certain holidays occur, the length of certain holiday
periods, and the date on which certain holidays occur within the fiscal quarter,
may also affect the Company's quarterly results of operations.

RESULTS OF OPERATIONS

The following table sets forth the Company's results of operations as a
percentage of total operating revenue for the three and six months ended June
30, 2000 and 1999:

THREE AND SIX MONTHS ENDED JUNE 30, 2000 AND 1999 RESULTS OF OPERATIONS

The Company's results of operations include the operating results of On-Time
Delivery and LSX Delivery (collectively the "acquisitions"). The purchase of
On-Time Delivery occurred during the first quarter of 1999 and the acquisition
involving LSX Delivery occurred during the second quarter of 1999. The results
for the acquisitions are included as of their respective purchase dates.

Operating Revenues. Total operating revenues increased $29.9 million, up 13.1%,
and $49.7 million, up 11.7% for the three and six months ended June 30, 2000,
compared to the same periods in 1999.

Passenger services revenues increased $26.1 million, up 13.7%, and $41.9
million, up 11.8%, for the three and six months ended June 30, 2000, compared to
the same period in 1999. The increases in regular route revenues reflect the
impact of a 6.9% and 5.6% increase in the number of passengers carried for the
three and six months ended June 30, 2000, combined with 5.4% and 3.7% increases
in yield and 1.1% and 2.0% increases in average trip length.

Package express revenues increased $0.1 million, up 0.6%, and $1.3 million, up
6.5%, for the three and six months ended June 30, 2000, compared to the same
periods in 1999 (including $0.4 million and $1.7 million related to the
acquisitions). Excluding the acquisitions, the Company experienced a slight
decrease due to reduced standard product deliveries (the traditional, low value,
terminal to terminal market segment) offset somewhat by gains in same day and
priority product deliveries.

Food services revenues increased $1.1 million, up 10.8%, and $2.8 million, up
15.7%, for the three and six months ended June 30, 2000, compared to the same
periods in 1999. Food services revenues increased over the prior year due
primarily to the increase in passenger traffic and the addition of eight
in-terminal restaurants that were previously concessionaire-operated Burger King
locations.

Other operating revenues, consisting primarily of revenue from charter and
in-terminal sales and services, increased $2.6 million, up 15.2%, and $3.7
million, up 11.7%, for the three and six months ended June 30, 2000, compared to
the same periods in 1999. The increases are attributable to higher tenant
income, subsidy income and long distance commissions somewhat offset by a
reduction in interest income.

Operating Expenses. Total operating expenses increased $21.9 million, up 9.9%,
and $38.7 million, up 9.0%, for the three and six months ended June 30, 2000,
compared to the same periods in 1999. The increase is attributable to 5.7% and
4.7% increases in bus miles operated for the three and six months ended June 30,
2000, increased fuel cost, higher driver wages, increased terminal salaries,
increased ticket and express commissions due to higher sales and $0.4 million
and $1.6 million for the three and six months ended June 30, 2000 related to the
operations of the acquisitions.

Maintenance costs increased $2.2 million, up 10.4%, and $3.0 million, up 7.1%,
for the three and six months ended June 30, 2000, compared to the same periods
in 1999, due to increased bus miles and higher labor costs.

Transportation expenses which consist primarily of fuel costs and driver
salaries, increased $8.8 million, up 16.1%, and $17.5 million, up 16.7%, for the
three and six months ended June 30, 2000, compared to the same periods in 1999,
due primarily to increased bus miles, fuel costs, and higher driver wages.
Transportation expenses increased on a per-mile basis by 10.1% and 11.6%, for
the three and six months ended June 30, 2000, due largely to higher fuel prices
in 2000 compared to the prior year, and to the impact of the driver wage
increases. For the three and six months ended June 30, 2000, the average cost
per gallon of fuel increased to $0.842 and $0.861 per gallon, compared to $0.576
and $0.531 per gallon during the same periods in 1999, resulting in increased
fuel cost of $4.1 million and $9.5 million.

Agents' commissions and station costs increased $3.6 million, up 8.3%, and $6.2
million, up 7.4%, for the three and six months ended June 30, 2000, compared to
the same periods in 1999. The increase is primarily due to commissions from
increased ticket sales, terminal salaries associated with staffing for the
increase in passengers, terminal salary raises and the inclusion of the
acquisitions.

Marketing, advertising and traffic expenses increased $1.0 million, up 14.2%,
and $1.5 million, up 10.7%, for the three and six months ended June 30, 2000,
compared to the same periods in 1999, due to an increase in spending to support
the increase in revenues.

Insurance and safety costs increased $1.3 million, up 10.2%, and $1.1 million,
up 4.6%, for the three and six months ended June 30, 2000, compared to the same
periods in 1999. The increase is principally due to the increase in revenues and
bus miles operated.

General and administrative expenses decreased $1.1 million, down 3.6%, and $0.4
million, down 0.7%, for the three and six months ended June 30, 2000, compared
to the same periods in 1999 due a reduction in expenses associated with
remediation of the Company's computer systems related to the Year 2000
preparation mostly offset by higher costs related to the increase in revenues
and higher health insurance costs in the year 2000. For the three and six months
ended June 30, 1999, Year 2000 expenses totaled $1.4 million and $2.7 million,
respectively.

Depreciation and amortization increased slightly during the three months ended
June 30, 2000 and increased by $0.8 million, or 3.8%, for the six months ended
June 30, 2000, compared to the same periods in 1999. The increases are primarily
due to higher capital expenditures in prior periods, and goodwill amortization
attributable to the acquisitions.

Operating taxes and licenses expense increased $1.2 million, up 8.5%, and $1.8
million, up 6.1%, for the three and six months ended June 30, 2000, compared to
the same periods in 1999 due to increased payroll taxes resulting from increased
salaries and head-counts related to higher business volume (including increased
miles operated) and increased fuel taxes resulting from increased miles.

Operating rents increased $3.1 million, up 17.2%, and $5.0 million, up 13.5%,
for the three and six months ended June 30, 2000, compared to the same periods
in 1999 due to the increase in revenues and an increase in the number of buses
financed under operating leases.

Food services cost of goods sold increased $0.7 million, up 10.4%, and $1.6
million, up 13.5%, for the three and six months ended June 30, 2000, compared to
the same periods in 1999, primarily due to the increases in food services
revenues.

Other operating expenses increased $1.0 million, up 144.7%, and $0.7 million, up
40.6%, for the three and six months ended June 30, 2000, compared to the same
periods in 1999 primarily due to losses on disposal of property, plant and
equipment experienced during the second quarter of 2000.



                                       12

Interest expense increased $0.5 million, up 9.2%, for the three months ended
June 30, 2000 and decreased $0.6 million, down 5.4%, for the six months ended
June 30, 2000, compared to the same periods in 1999. For the three month period,
the increase is attributable to interest on the installment conversion payments
to certain preferred stockholders. For the six-month period, the decreased
expense is due to a reduction in the average debt outstanding.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal sources of liquidity are cash flow from operations and,
previously, funds provided by the Company's parent, Laidlaw Inc. ("Laidlaw"). In
its Quarterly Report on Form 10-Q for the period ended May 31, 2000 (the
"Laidlaw Form 10-Q"), Laidlaw reported that it had declared an interest payment
moratorium on all advances under its syndicated banking facility (the "Laidlaw
Facility") and on certain of its debentures totaling $1.954 billion (the
"Laidlaw Debentures"). As a consequence of the Laidlaw Facility covenant
violations and interest payment moratorium, the Laidlaw Facility and the Laidlaw
Debentures have become due on demand. Laidlaw is endeavoring to renegotiate and
restructure the Laidlaw Facility and Laidlaw Debentures. In the Laidlaw Form
10-Q, Laidlaw further reported that should repayment be demanded for the Laidlaw
Facility and/or the Laidlaw Debentures, Laidlaw may not be able to satisfy these
obligations, nor other obligations which become due in the normal course of
operations and may not be able to continue to operate as a going concern.
Additionally, Laidlaw has advised the Company that cash funding, after August 1,
2000, would be limited to the cash flow generated by the Company from its
operations and that additional funds from Laidlaw would not be available.
Laidlaw further requested and authorized the Company to seek additional funding
from outside financing sources for its seasonal cash requirements and capital
expenditure programs. The Company is in the early stages of seeking this
financing and there can be no assurances that alternate sources of financing, in
amounts necessary to meet Company's needs, will be available, and if available,
that the cost of such financing will not materially exceed the cost currently
experienced by the Company. Should alternate sources not be available or not be
sufficient to meet the Company's needs, the Company may be required to curtail
or defer non-essential or essential capital and operating expenditures and may
not be able to satisfy its obligations as they become due in the normal course
of operations and may not be able to continue to operate as a going concern. As
a result, the Company may not be able to realize its assets and settle its
liabilities in the normal course of operations.

The Company's primary uses of cash are for operating activities, capital
expenditures and debt service. As of June 30, 2000, the Company had $176.1
million of long-term indebtedness (including a current portion of $6.1 million,
excluding $29.3 in payments due to former holders of the Company's Redeemable
Preferred Stock, discussed below), principally, its 11-1/2% Senior Notes due
2007 in the amount of $150 million. Interest on the Senior Notes is payable in
semi-annual installments of $8.6 million, each April and October. The Company
has ordered ninety (90) new motor coaches from Motor Coach Industries
International, of which 33 were delivered as of the date of this report, with
the remaining buses to be delivered this fall. Payment for the buses, totaling
$27.5 million, is payable to Motor Coach in December 2000. As indicated above,
the Company will be seeking interim and permanent lease or purchase money
financing for these buses.

Net cash provided by operating activities for the six months ended June 30, 2000
was $18.2 million, an increase of $9.5 million from the $8.7 million generated
during the same period of 1999. The increase is due primarily to the improvement
in operating income. Net cash used for investing activities for the first half
of 2000 was $12.7 million compared to $85.1 million for the first half of 1999.
The decrease is due to $44.0 million in sale-leaseback proceeds received in the
first half of 2000, compared to no sale-leaseback proceeds during the same
period of 1999, reduced capital expenditures and no acquisition spending during
the first half of 2000 compared to the same period of 1999. Net cash used for
financing activities in the first half of 2000 was $5.5 million versus $77.8
million cash provided by financing activities during the same period in 1999.
The $83.4 million reduction in cash provided from financing activities is
primarily due to the improved operating income in 2000, as well as reduced
capital expenditures and increased sale-leaseback proceeds during 2000.

At March 31, 2000, the Company had 1,344,850 shares of Redeemable Preferred
Stock outstanding, which shares were convertible into $44.8 million in cash in
the aggregate. Following the presentation of a significant number of these
shares for conversion, the Company and Laidlaw entered into agreements or
otherwise made payment arrangements with converting holders representing $37.6
million of aggregate value whereby such parties would receive their conversion
proceeds in installment payments through August 31, 2000. During the three-month
period ending June 30, 2000, the Company made $8.3 million in conversion
payments to the converting holders and, subsequent to June 30 through August 11,
2000 the Company has made an additional $19.7 million in conversion payments. As
of August 11, 2000, $9.6 million remained payable under these agreements. As of
June 30, 2000, excluding the shares for which conversion payments were being
made, the Company had 217,550 shares of Redeemable Preferred Stock outstanding,
which shares are convertible into $7.3 million in cash in the aggregate.

On May 9, 2000, a lawsuit was filed by two holders of Redeemable Preferred Stock
alleging: (i) that the Company, in violation of federal securities laws,
materially misrepresented facts, and omitted reference to material facts, with
respect to the conversion rights of holders of the Redeemable Preferred Stock
and (ii) that the Company was in breach of the rights of holders of Redeemable
Preferred Stock as contained in the Company's Restated Certificate of
Incorporation. The suit sought recovery from the Company of the conversion
payments relating to the Redeemable Preferred Stock held by the plaintiffs,
totaling $17.4 million, costs, attorneys' fees and interest. Laidlaw was also
named as a defendant in the suit. Plaintiffs alleged that Laidlaw tortiously
interfered with the Company's obligations to the plaintiffs and sought
injunctive relief, actual and punitive damages, costs, attorneys' fees and
interest. The suit, Reliant Trading and Deutsche Bank AG, London Branch v.
Greyhound Lines, Inc. and Laidlaw Inc., is pending in the United States District
Court for the Eastern District of Wisconsin, Civil Action 00-C-0656. On May 31,
2000, another holder of Redeemable Preferred Stock, Silverado Arbitrage Trading
Ltd., filed a motion with the Court seeking to intervene in the lawsuit.
Silverado sought recovery of conversion payments totaling $4.9 million, costs,
attorneys' fees and interest from the Company and sought injunctive relief,
actual and punitive damages, costs, attorneys' fees and interest as to Laidlaw.

On June 8 and 15, 2000, the Company and Laidlaw reached separate confidential
settlements with the plaintiffs and Silverado whereby they will receive payments
from the Company of the conversion amounts for their Redeemable Preferred Stock,
together with interest accruing from May 1, 2000, in weekly installments through
August 31, 2000. Pending fulfillment of the Company's obligations under the
settlements, the foregoing litigation has been stayed. As of the date of this
report, the Company has made all required payments called for under the
settlement agreements.
